  • Look for a depression in the ground a couple of feet in diameter and located between the septic tank and the drainfield. The D-box is normally not very deep, often between 6″ and two feet to the top of the box. You may also see a pattern of parallel depressions, typically about 5 feet apart, that mark the individual drainfield leach lines.

Where is the distribution box in a septic system?

If your layout consists of a rectangular and level drain site, your distribution box is likely to be located near the edge of the drain field, closest to the septic tank. You can also look for a depression in the ground between the septic tank and drain field a couple of feet in diameter.

What is the minimum safe distance from the septic tank?

At least 15m from the nearest water supply. This is a minimum and should be more if the ground is rocky and fissures could take the outflow further. It should be at least 3m from the nearest building. Avoid areas where rainwater would stand or flow over the tank or vehicles could drive over it.

Can you pump septic from distribution box?

Your distribution box does not need to be pumped as your septic tank does. The distribution box will be down from the septic tank, close to the leach or drain field.

Does every leach field have a distribution box?

Distribution Box: Most, but not all, systems have a d-box. Once the effluent is separated in the septic tank, the distribution box, located in the leach field, dispenses the effluent into the leach field.

How much does it cost to replace a distribution box on a septic system?

Septic Distribution Box Replacement Cost Replacing a septic distribution box costs between $500 and $1,500. This component is also called the D-box. It is very important, responsible for controlling the even distribution of wastewater into the leach field.

Can you have a dishwasher if you have a septic tank?

DON’T. use your dishwasher, shower, washing machine and toilet at the same time. All the extra water will really strain your septic system. put items down your sink or toilet that can easily be thrown into the trash.

Can you build a deck over a septic tank?

You should never build a deck over a septic field; doing so will prevent the natural draining and dissipation of the effluent. This can ruin the septic system, not to mention releasing foul smells into the air all around your deck. The dissipating effluent can also rot the deck from underneath.

How far down is a leach field?

A typical drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36 inches.

Should my septic distribution box have water in it?

A septic system distribution box should not be full of water. As effluent water leaves the septic tank towards the drain field, it first enters the distribution box. If the distribution box is full, there is a problem with clogged leach lines or a failing drain field.

Does a septic tank always have water in it?

A septic tank should always be “filled” to its normal liquid level, or the bottom of the outlet pipe which carries effluent to the absorption area. This normal liquid level is usually between 8” to 12” from the top of the tank on average (see picture at right).

What soap is safe for septic systems?

Whether you are handwashing dishes or using a dishwasher, these are safe choices:

  • Aldi Foaming Dish Soap.
  • Amway Home Dish Drops Automatic Dishwashing Powder.
  • Dropps Dishwasher Pods.
  • ECOS Dishmate Dish Soap.
  • Method Dish and Dishwasher Soaps.
  • Seventh Generation Dish Liquid.

How far down is a distribution box?

The D-box is normally not very deep, often between 6″ and two feet to the top of the box. You may also see a pattern of parallel depressions, typically about 5 feet apart, that mark the individual drainfield leach lines. The D-box will at or near end of the drainfield area that is closest to the septic tank.

How far should leach field be from house?

Local codes and regulations that stipulate the distance of the septic tank from the house vary depending on the locale, but the typical minimum distance is 10 feet.

Can a distribution box get clogged?

One of the most common septic tank problems arises when the distribution box is damaged or clogged, preventing the flow of water from the septic tank into the drainfield. In most cases, a qualified plumber can fix this problem quickly and easily before it becomes a serious issue for the household septic tank system.

How far is D box from septic tank?

You can identify your septic tank without assistance from a professional, but it is a good idea to have someone who is properly educated in septic tank maintenance examine and maintain your septic tank on an ongoing basis for you. If your tank is equipped with an effluent filter, it should be rinsed into the open septic tank rather than on the ground in your yard. In addition, it may be beneficial to make a note of the position of the septic tank after it has been discovered. The information provided here will be useful to anybody else who may require access to the septic tank in the future.

The presence of septic tanks in the open is required due to the release of combustible and hazardous gases.

  • Is there enough room for septic fields? Is there enough space on this site to accommodate a typical tank and drainfield? The presence of a septic tank and drainfield is improbable on a tiny property, although it is possible that a cesspool is being used instead. It’s important to remember that when it comes to septic repair, it may not be possible to employ a cesspool or other non-conforming septic system since it has been “grandfathered.” Does the property have any site encumbrances that could make the installation or replacement of the septic system difficult or expensive, such as nearby streams or lakes or storm drains and trees, rocky or steep site conditions (see our septic failure case examples), or restricted distances from a well or property boundary? During and after the dye test, make sure to examine surrounding streams and lakes for contamination. Whether or if there are pipelines flowing from the property into a neighboring stream, perhaps discharging septage, should be investigated.

  • We observed water, most likely septic effluent, rushing over a rock right below the claimed (new) septic tank when we arrived for our inspection. That it came from the septic system was established by the color we used. Once again, this is the identical granite ledge that enhanced effluent flow as soon as we began our septic testing. Septic wastewater from this system had been discharging to the surface through an overflow pipe or from the bottom of a tiny, home-made seepage pit, which itself was lying on solid rock for decades, delivering septic effluent downstream to Wappingers Creek and then to the Hudson River. The agent advised us that the system was in fine operating order, but that the owners had just added a new septic tank solely for the purpose of improving the “curb appeal” of the property. Unfortunately, a whole steep slope system was required to handle the wastewater, which proved to be too expensive. The money spent by the vendor was a poor investment.

  • What is a distribution box
  • Why should you look for one
  • And how to locate one

When your septic tank is operating well, it is out of sight and out of mind, and you may not be aware of all of the subterranean components, such as the distribution box, until something goes wrong. One of the numerous septic tank inquiries that many homeowners have is where the various pieces are located.

The ability to understand what this little but critical component performs, where to find it, and what sort of care it required can assist you in keeping your septic tank in good working order.

What Is a Distribution Box?

Distribution box is a tiny box that is installed after the septic tank but before the drain field to distribute wastewater. In most cases, they are composed of either polymer plastic or concrete, and they have many apertures on various sides where the drain field lines are connected to the box. As an example, consider it to be a connection point for the lines that go throughout the leach field. The actual size and style of your system will be determined by your system. In order to ensure that the effluent from the septic tank is distributed uniformly over the drain field, it has been designed to do the following: In order to take advantage of gravity, the distribution box is often placed slightly downhill from the septic tank.

  1. In addition, the box is often equipped with spinning components that aid in the distribution of consistent volumes of wastewater in different sections of the leach field.
  2. The wastewater might gather in an uneven manner if this is not done, with some portions of the leach field receiving all of the wastewater and other regions receiving none.
  3. Regular inspections of the distribution box as part of normal septic tank maintenance can help to verify that everything is going well.
  4. You may also inspect the distribution box for damage and assess whether it is necessary to replace it.
  5. Things such as driving over the box, tree roots growing into it, heavy sludge accumulation, and other damage to the box might compel you to replace it sooner than you would have otherwise thought necessary.
  6. Due to its role in moving effluent from the septic system’s tank to the septic drain field, it seems logical that the box should be installed between them.
  7. Distribution boxes are typically just 6 inches to 2 feet deep, depending on the manufacturer.
  8. Site plans or a drawing of the authorized system design should still be available if you have them, and the distribution box should be clearly noted on them.
  9. Be aware that some smaller systems may not have distribution boxes, while most systems do have distribution boxes.
  10. It is possible to notice parallel depressions that represent the leach lines and can direct you to the distribution box in rare occasions.

By running a plumbing snake from the septic tank outlet to where it stops, which should be the distribution box, you may get a general estimate of how far it is to the distribution box.

How far from septic tank is distribution box?

Distribution box is a tiny box that is installed after the septic tank but before the drain field to collect wastewater. They’re often composed of plastic or concrete, and they feature many ports on various sides through which the drain field lines may be connected to the box. Consider it to be a nexus for the lines that run throughout the leach field, bringing them all together. According on your system, the precise size and design will differ. In order to ensure that the effluent from the septic tank is distributed uniformly over the drain field, it has been designed to do the following.

  1. Consequently, the effluent may flow more readily into the distribution container.
  2. It is critical that the distribution box in your septic system is in excellent functioning order.
  3. Because of this, the drain field may become oversaturated in that particular location.
  4. You may detect minor problems before they become serious enough to cause a full failure with this method of checking for problems.
  5. If your distribution box is composed of concrete, it should last around 20 years.
  6. It is beneficial to have a broad concept of where the distribution box is located while looking for it.
  7. In most cases, it’s on the border of your drain field, at the end of the field that’s closest to your septic tank.
  8. This can help you narrow down your search, but you’ll still need some further information to pinpoint the precise position of the place.
  9. In the event that you are certain that you have a concrete distribution box, you might use a probing rod to locate the subsurface distribution box.
  10. An occasional little dip in the earth, generally a few of feet broad, can be found above the distribution tank.

You may also acquire an approximate measurement to the distribution box by running a plumbing snake from the septic tank outlet until it comes to a halt, which should be the location of the distribution box.

How far from septic tank is distribution box? – Related Questions

These distribution boxes are available in three different sizes: Distribution boxes with four holes can handle up to three field lines, distribution boxes with six holes can handle up to five field lines, and distribution boxes with eight holes can handle up to seven field lines.

Is it OK to have a dishwasher with a septic tank?

Contemporary dishwashers, like newer washing machines, operate more effectively and consume significantly less water, which is beneficial to the septic tank system. Having said that, the detergent used in the dishwasher is frequently the source of septic tank issues as well. Septic tank microorganisms are at risk from the presence of such diluted detergent.

Is it OK to have a dishwasher with a septic system?

The Use of Dishwasher Pods with Septic Tanks When non-toxic, organic produced detergent pods are used, septic systems are not harmed in any way. They are easily dissolved in aqueous solutions. They do not clog the pipes and do not have an effect on the staining process.

How much does it cost to replace a distribution box?

a concrete distribution box (also known as a D-box for short) is a smaller tank that is responsible for distributing liquids out to the leach field. The typical cost of replacing a distribution box is between $600 and $1300 dollars.

Can a distribution box get clogged?

Openings that are clogged As a result of clogged or broken pipes in the distribution box, wastewater may only be released into the leach field through one or two of the ports on the distribution box.

How does septic distribution box work?

The distribution box, like the majority of your septic system, is powered by gravity. It is known that liquid waste enters the box through a single pipe and is split equally in order to escape the box through the drain system. Due to the fact that the leach field and box are placed below the septic tank, the wastewater flows downhill as it approaches the container.

How long do septic systems last?

Septic systems have a lifespan of 15-40 years, with the length of time varying depending on a variety of conditions, including those described above. Is it necessary to get your Sand Filter Septic System serviced? Allow our septic system professionals to assist you.

Are garbage disposals bad for septic systems?

While it performs a good job of chopping up food and other big items into tiny bits, the particles it produces will not decompose in the septic system. Eventually, they make their way into your leach field, clogging it up with debris. In the event that you have a trash disposal as well as a septic tank, you should arrange servicing right away.

Why is my leach field sinking?

The surplus water will puddle around the pipes if the soil around them is incapable of absorbing it. Eventually, a piece of the septic system may actually sink, or the soil may wash away, giving the area a sunken appearance.

How do you clean out a septic tank drain line?

Cleansing Agent – White vinegar is a preferable choice since it is a natural cleaning agent that may help keep septic drains free of mold development and foul odors. The American Plumbing Association recommends that you pour one cup of vinegar down the drains once a week and allow it to soak for around half an hour before flushing it through the system with water.

Is Dawn dish soap safe for septic?

For these reasons, Dawn is a safe product for use in septic systems, and it does not include any of the potentially dangerous components listed above.

How long do distribution boxes last?

A concrete D-box may normally endure for up to 20 years in most conditions. Nevertheless, if sludge accumulation, tree root invasions, bad maintenance, heavy gear on top of the box, or other concerns result in permanent damage to your distribution box, you may be required to replace it entirely.

Can a leach field be restored?

A blocked drain and the spilling of raw sewage into the ground surface are both possible consequences of a malfunctioning drainfield. A faulty drainfield may and should be repaired as soon as possible in order to minimize lasting harm. Drainfield additives, including biological, organic, and inorganic components, can be employed to restore the functionality of a failing drainfield.

How do I know if my drain field is failing?

It is possible for sewage to back up into the residence when the drainfield collapses or becomes saturated with water. It is possible that wet, soggy regions could form above or around the drainfield, and that spongy brilliant green grass will cover the whole area. Additionally, smells may be present around the tank or drainfield.

Should my distribution box be full of water?

The distribution box of a septic system should not be completely filled with water. After leaving the septic tank and making its way to the drain field, effluent water first passes through the distribution box. An overflowing distribution box indicates blocked leach lines or an overflowing drain field as the cause of the overflow.

Does a septic tank always have water in it?

A septic tank should always be “filled” to its normal liquid level, which is the level at which the effluent exits the tank and flows to the absorption area, according to the manufacturer. On average, this typical liquid level is between 8″ and 12″ below the tank’s maximum capacity, depending on the model (see picture at right).

What is a septic design?

Inspect and pump the water Frequently Inspection of the ordinary residential septic system should be performed by a septic service specialist at least once every three years. Household septic tanks are normally pumped every three to five years, depending on how often they are used.

How Far Down is My D-Box Lid?

When you have nothing better to do on a leisurely Saturday afternoon than sit around in your yard and just relax, you should do it. However, just as you are about to fall asleep, your wife walks up to you and reminds you that you have an errand that has been outstanding for more than a month. Yes, it is now your responsibility to identify and examine your distribution box, often known as a “d-box.” If you haven’t completed your planned self-maintenance for your septic system by now, you will end up like your neighbor, whose entire yard has been turned into a sewage kiddie pool due to a clogged drain.

  • What method will you use to locate your d-box lid, and how far down should you look?
  • A septic system’s drain field is an important component that you must identify in order to be able to do routine maintenance on your septic pipes.
  • The first step is determining the best location for excavation.
  • It is critical that you obtain accurate information on your septic system installation.
  • However, you should not rely on this since the diagram or viewpoint that you can obtain from the permission office may very well be the original plan and may differ from the real buried object in your yard.
  • If you have already acquired the diagram but believe that it will not be of much use, simply check around your yard for dark green grass that grows on top of your drain field and you will be able to tell.
  • If you can figure out where these lush green strips are coming from, it will be the location of your d-box, and it would be great if you started excavating there right away.

Using a fine metal dowel, slowly press your way around the tank area until you find the outflow line that is exiting the tank, then stop.

Tap down on the exit line with the probe and walk a few feet to the right.

The “finder” approach will take you right to the d-box, and it may also be handy for mapping out your whole field, including its depth, after you grow accustomed to utilizing it.

Once you’ve discovered the location of the d-box lid, experts estimate that you’ll have to dig two to four feet below the surface.

They make an attempt to locate the metal reinforcement of the d-box with a metal detector, but are unsuccessful.

The concrete container, or a wayward pebble, might be the source of the problem.

Of course, the greater the distance between the d-box and the tank, the deeper the tank will be.

You must be aware of the depth to which you are going to have a section of your yard dug before you proceed.

Once you’ve obtained that initial and critical information, you’ll want to make sure the it is easily available for future maintenance work.

Even though it might be difficult for those who have an underground septic system to discover their distribution box, it is possible to locate, check and service them with a little effort.

Installing D-Boxes

A drop box should be positioned level and should include an inspection port on the side for easy access.

Interested in Distribution?

Receive articles, stories, and videos about Distribution sent directly to your email! Now is the time to sign up. Distribution+ Receive Notifications Septic wastewater is delivered to the soil treatment area by gravity in two basic ways: through the distribution box and through the drop box (see illustration). Generally speaking, distribution boxes are employed in subsurface bed systems as well as in a succession of trenches on flat terrain. Parallel distribution is the term used to describe this sort of distribution.

Basic definitions

Distribution boxes are built with an intake at the highest level and several exits at a single lower elevation, as shown in the illustration. It is theoretically possible that the box will then distribute the effluent evenly amongst the trenches. As a result, most state and municipal rules require that every trench supplied by a distribution box be the same length as the preceding trench. Equitable distribution is extremely unusual, if ever, to occur in the real world. Usually, one of the exits is somewhat lower than the others, or organic material development in the box or the pipe causes the flow to concentrate in a single trench, as seen in the illustration.

Distribution boxes should thus only be used on level sites or in bed systems that have been created on a level surface.

The trench outlet pipes are positioned at the bottom of the box, towards the bottom of the box.

When the effluent flows via a supply pipe that is laid with at least a one-inch drop to the next box in the sequence, it is considered to be clean.

Keeping it level

It is critical to put distribution or drop boxes on a level surface, regardless of their purpose. Depending on the soil stability, they can be planted directly on level natural soil or over three to six inches of coarse sand or washed pea rock if there is worry about the stability of the natural soil. The support and bedding of the inlet and output pipes must be adequate. One typical issue we notice with drop boxes is that the trenches where the supply pipes are put are excavated to an excessive depth.

Backfilling without sufficient support can cause the boxes to get out of level, or even worse, it can cause the supply lines to break or crack.

Installers who fail to locate their boxes at the right altitudes risk over-excavating their trenches, resulting in their not having the required separation distance from limiting circumstances after they are finished.

It is critical that the boxes remain waterproof and resistant to root penetration.

If you are responsible for making a concrete box waterproof, you should use a flexible rubber boot rather than attempting to seal the box with concrete or mortar. The concrete will fracture over time and during the backfilling process, allowing roots and water to seep through.

Regulating flow

There are a variety of flow-control mechanisms that may be fitted in each type of box to allow the flow to be adjusted to the specific trenches. Those responsible for system administration and biomat production are referred to as “supervisors.” They are not designed to make up for improper installation techniques! There are also several patented items on the market that employ the notion of a “tipping bucket” to dose and rest the gravity trenches, which are available for purchase. When using these technologies, both you and the homeowner must know that they require a greater degree of maintenance and care than is currently available.

  1. An additional effective installation technique that enables for easy inspection and administration of the system is to run solid pipe from the box to the surface of the ground.
  2. Poor practice includes the use of earthen dams and pipe layouts to carry wastewater between trenches without the use of a drop box, which is an example of terrible practice.
  3. We have also discovered that at each stepdown or crossing point, there is a region where effluent is likely to re-enter the atmosphere.
  4. This next month, we’ll take a look at the right methods for constructing trenches and beds for gravity distribution.

Should a Septic Tank Distribution Box be Full of Water?

When we initially moved into our present home, which included a septic tank, I knew I wanted to learn everything I could about septic systems before we could utilize it. I was aware that they are buried underground, that they must be pumped out on a regular basis, and that they may be pricey. That was pretty much the extent of my knowledge. However, the distribution box has suddenly emerged as one of the components that is strangely intriguing. I honestly have no idea why this is happening. It took us a couple of years to realize that we even had a distribution box in the first place.

If you’re wondering whether or not a distribution box should be filled with water, keep reading.

After leaving the septic tank and making its way to the drain field, effluent water first passes through the distribution box.

An overflowing distribution box indicates blocked leach lines or an overflowing drain field as the cause of the overflow.

Of course, the bad news is that it is possible that there will be a serious problem with the leach field. Allow me to go into further detail about what the D-box is meant to perform and some of the issues you can have if yours is clogged with water.

What is a Septic System Distribution Box?

First and foremost, it should be noted that not all septic systems are equipped with a distribution box. Older systems may not be able to do so. Given that you’re asking why one would be full, I’m going to presume you’re aware that you have one, correct? Despite its importance, the distribution box is one of the most underappreciated components of a sewage system. Basic systems include one pipe running from the home to the septic tank on one side, with all of the waste water from the house going into the tank.

  • Meanwhile, microorganisms are hard at work breaking down all of the unpleasantness around the clock.
  • (These are the same item, yet some people refer to it as one and others as the other.) (It’s pronounced Potahto.) The drain field is comprised of a number of long plastic tubes (usually 2–6) that have holes in them.
  • The distribution box is responsible for ensuring that the effluent water is distributed uniformly amongst all of the leach lines.
  • The pipe from the septic tank is linked to one end of the pipe, and then each of the leach lines is attached to the other end of the pipe.
  • This movie provides a very succinct review of everything.

Why is My Distribution Box Full of Water?

It’s clear now that you understand how the distribution box works (assuming you didn’t already know how it worked, that is), why it shouldn’t be filled with water. Maybe if you were experiencing a really strong rain that had been going on for hours and then did a load of laundry, the D-box would momentarily be full since the leach field was saturated from the heavy rains and adding a washing machine full of water would make the D-box temporarily full. But even if it were, I’m not convinced it would be completely packed.

So, what may be the source of your D-overflowing box’s water supply?

You could have a clog

If the distribution box is consistently full, it is reasonable to conclude that there is a problem with the water departing or entering the system. This means there might be an obstruction in one or more of the leach lines, preventing water from flowing into them or draining out of them at a rapid rate. Roots from adjacent trees (which shouldn’t really be nearby) might be growing into the leach lines, and this could be the cause of the problem. It should not be choked by grass or wildflowers growing above the area, as the leach lines should be at least 18″ below the surface of the ground.

Alternatively, it might be clogged with debris from the septic tank, particularly from the sludge or scum layers.

If only the effluent water is present at the level of the outlet pipe, then the tank has not been pumped or treated frequently enough, and either the scum layer (fats, oils, floating things) has become too thick to allow it to drain too far down into the tank, or the sludge layer (poo) has become too thick to allow it to drain all the way up to the outlet level.

The Drain Field is Failing

I believe this is the most likely possibility, however it is not encouraging news for the time being. If the drain field is failing, it indicates that the water is not draining as rapidly as it should, and as a result, the water is pooling in the leach lines, leaving the water in the distribution box with nowhere else to go. Drainfields are susceptible to failure if the earth underneath them has become compacted as a result of vehicles driving over or parking on them. Aside from that, if you have an above-ground pool over the leach field, this can also cause the earth to be compacted.

I recall a homeowner whose neighbor had a lot of water overflow from his land, which I found to be a nuisance.

Fixing a Failing Drainfield

I don’t want to dive too much into the details of how to repair a failing drainfield at this point, but there are a variety of methods available depending on the situation. The land may be fractured if you put large amounts of air into it at high pressures and speeds. It’s possible that you’ll have to replace the complete drainfield or only a few lines. It depends, which I realize is not a very helpful response. They live next door to us, and their drainfield was wrongly placed long before they purchased the property.

It was a flop.

Catywumpus D-Box

The only other thing that may be causing the distribution box to remain full is if it is extremely slanted up in some way, such that the pipes leading to the leach field are angled up and the water is just having a difficult time getting into the distribution box. It would take a significant movement in the D-box to create that type of a complication. It is not impossible, but it is extremely unlikely.

Can I Fix My Clogged Leach Lines?

It is quite possible to check for and attempt to remove a blockage on your own if you are physically capable of doing so. If you’re not sure, give a septic company a call and inquire about how much it could cost for them to come out and inspect it. That alone could be enough to spur you on!

A septic system is a type of on-site recycling system that processes wastewater and recycles it back into the environment. A septic system may perform its functions safely and efficiently for a long period of time if it is properly planned, constructed, and maintained. Failure due to improper design, installation, usage, and/or maintenance can result in a premature and expensive failure. To safeguard your investment and the environment, we encourage you to learn how your system works, to use it appropriately, and to keep it in good working order.

  1. Septic Tank (also known as a septic tank): Waste water is channeled from the residence to the septic tank by gravity.
  2. Bacteria breakdown a portion of the solids, resulting in the formation of sludge.
  3. Baffles fitted at the tank’s inlet and exit help to prevent scum and particles from escaping through the openings.
  4. There will be no non-biodegradable items in a well kept septictank; the sludge, scum, and grease levels will be less than one-third the total liquid level in the tank; baffles will be installed and correctly designed; and the filter, if applicable will be generally clean and unobstructed.
  5. This is accomplished by the use of a pump or siphon.
  6. The operation of an effluent pump is dependent on power.
  7. When an effluent pump is used, the pump’s operation is triggered by on and offfloats that are linked to the pump.

An alarm system, as well as the control box, are frequently installed in the house.

As soon as the effluent has been separated in the septic tank, it is dispensed into the leach field via thedistribution box, which is placed inside the leach field.

Drain field: A solid pipe travels from the septic tank to the drain field where wastewater is routed into one or more perforated pipes arranged in trenches or beds of gravel, as well as a perforated concrete structure, to be disposed of properly.

Here, the water gently seeps into the dirt beneath the surface.

The cleaned wastewater then either travels into the groundwater or evaporates from the soil, depending on the circumstances.

Planting trees, on the other hand, is not recommended since the roots of huge plants might choke or damage the pipes.

Cracking pipes, causing the distribution box to settle and effluent to flow unevenly into the drain field, and/or compacting soils, smothering the leach field are all possible consequences of these operations.

Author:hj (AZ)There is no hard and fast rule, but the distribution box would normallybe straight out from the tank’s outlet within ten feet. It will also be down at the level of the outlet opening on the tank.
