Before you build or modify unit verify rules and regulations.

Codes vary by local health departments, not state.
We are not aware of the codes or rules. We are not aware of what tanks or items you need.


Not sure what you need? Forward all water tank information to your local health department before purchasing to be sure these tanks will pass your local inspection, this is your responsibility.


Tanks no longer have the NSF logo molded into them due to changes NSF made regarding the use of the NSF logo. The NSF Company does not allow for end users to use the NSF logo unless each item has been inspected and a certification paid for, the material that all of our tanks are made from are still the same NSF Certified Material, adding this extra step of certification is an unnecessary step but generates revenues.

The NSF Company does not allow vendors/manufacturers to link to the NSF paperwork unless verified NSF products are being used, our company has been verified and links to the NSF Certified Materials. If needed your inspector can check on this regarding our company and website as we have already provided this information to the NSF company and have been advised on how to correctly use/link to the certification information on our website.

Mobile Build To Do List



What to ask on Fresh and Gray Water Tanks
Size (Gallons / Measurements / Fresh to Gray ratio)
Fittings (Size / Placement / Materials)
Filling Procedure (Lockable Fill Dish / Materials)
Tank Placement (Inside / Outside of unit)
Clean Out Requirements



Water Tank Percent Calculation Examples
Multiply (fresh tank size) x 1.15 (1 . 15%) = Tank needed
30 x 1.15 (15%) = 34.50
30 x 1.50 (50%) = 45



Do you have a"plug and play" or "concession kit"?
No, due to the facts that you will need to verify what size tanks will fit in your available space, length of hose needed, fill dish style, and verify regulations. Examples of Fittings you could use, depending on your application.


Items we carry that you may be able to use, verify before purchasing.

Fresh/Gray Tanks

Fittings & Hoses

Water Fill Dishes

12 Volt Water Pumps

Water Monitors



I have only so much room how many gallons can I get in that space?
We do not recommend sizes or verbally give measurements please look at the Water Tank List located at the top of each webpage to see all tanks Class A Customs currently manufactures. You would need to compare the measurements of the tank with your available space and determine the best tank for your needs and application.


What fittings will I need for my plumbing

This will depend on how you are setting-up your tank and will vary by application, we are not aware of what items you will be needing, please view the Plumbing Examples & Available Products


Be sure to Sanitize Tank before installing.





My health department doesn't care, they won't look... my builders said it is ok...
We hear this and then get the call needing a different tank sent overnight to meet a deadline. It takes very little time to verify requirements, this saves you time and money.
Forward the Water Tank List to your local health department before purchasing to be sure these tanks will pass your local inspection, this is your responsibility.

~ Fittings ~








At this time Class A Customs only installs the following fittings into our Fresh / Gray tanks

.5" NPT Female - fitting is open

1.5" NPT Female - fitting is closed, use a razor knife to cut membrane out - easiest when cut in halves

1.25" Outer Diameter x 2" Long Smooth Pipe / Boss Fitting (glues does not stick to pipe, it can not be sealed or capped)


If you are a manufacturer or OEM needing custom fittings please contact sales for more information, minimum quantity of 50 tanks will apply.






Where are the fittings located on the tanks?

Are there fittings on both ends of the tanks?

Please look at the photos of each tank as fitting placement can vary by tank, typically fittings are all located on one end of the tank.










What fittings will I need for my plumbing?

We are not aware of how to set-up your tank, set-up will vary by each application this is something you need to research. Have a certified technician install all parts to prevent product damage and personal injury. Please view our Plumbing Category for information on loose fittings we carry. Examples of Fittings you could use, depending on your application.





Each tank will come with at least one vent hole made during the manufacturing process, a permanently mounted patch is placed over this hole, this is not a fitting and does not unscrew.






There is glue flaking on my tank!

No glues or sealants are used to install the fittings, the residue left by putting the fittings in place is part of the material the tanks and fittings are made from and may spider crack or flake off over time, this in no way harms the tank or causes any usage issues.






Can I cut a hole in the tank and glue another fitting in?

No, fitting are spun welded into the tank, friction between the fitting and the tank causes both to melt and permanently seal, no additional glues or sealants are used to install the fittings. To add fittings or repair a damaged fitting we now offer Uniseal Fittings, please watch the included video for information.






How do I add fittings to my tank?
Uniseal Fittings allow you to put a fitting in any location, sizes range from .5" - 3"







I need a clean-out hole for my tank.
We do not offer clean-out ports at this time but there are many options online that allow you to install the needed clean-out port. Examples of Fittings you could use, depending on your application.







What fittings will I need for my plumbing?

We are not aware of how to set-up your tank, set-up will vary by each application this is something you need to research. Have a certified technician install all parts to prevent product damage and personal injury. Please view our Plumbing Category for information on loose fittings we carry. Examples of Fittings you could use, depending on your application.


Be sure to Sanitize Tank before installing.


It is recommended to use plastic NPT male fittings with plastic female NPT fittings to avoid damaging the threads, metal thread fittings can crush the plastic threads.

Very little, if any, pipe thread tape is needed using too much pipe tape will damage the threads. We do not recommend pipe dope as you can not remove the fitting later, if used be sure to use a food safe brand.
Do not over-tighten fittings as damage will occur.



All water tanks we carry must be vented, they are not pressurized tanks.
Have a certified technician install all parts to prevent product damage and personal injury.

Tank must have a large enough opening for air to freely move in and out of tank, this is called "venting" the tank. If tank is not properly vented tank will explode when filled or implode when emptied.


A garden hose is a pressurized water line, do not make a secured connection to the water tank with a pressurized line. Tanks need to be gravity feed, this allows for air to escape while the water is going into the tank. Our Basic Plumbing Diagram shows how an RV or food unit can be set-up using a gravity fill dish.




For my application I am going to use a pressurized line to the tank.

This will void any warranty on the tank. Turning a garden hose on half way does not work because you can control the amount of water flowing but not the pressure in the line, leaving the tank to fill risks exploding the tank. Examples of Fittings you could use, depending on your application.






What is a fill dish?

The fill dish is located on the outside of your unit so that you can easily add water to your tank without the need of opening a compartment or climbing under your unit. You can find the fill dishes in the Plumbing Category.


For adding water to the Water Tank you need a Gravity Fill Dish, the hose rests in the port it does not screw onto the port this allows you to place a garden hose into the Gravity Fill Dish port without making a sealed connection so the supply is not pressurized.

For using Water Directly from a garden hose you need a City Fill Dish, the hose makes a sealed connection and the water supply is pressurized, you can not hook this to your water tank and you do not need to go through your water pump.

We carry Gravity Fill Dishes, City Fill Dishes and Combo Fill Dishes that have both gravity and city, the benefit of having both is you can have a water tank of fresh water but if you go to a location that supplies pressurized water (campground - fair - etc.) you do not need to use your water tank supply of water you can simply use the water provided. Be sure to look at the provided example plumbing diagram for more reference.











 







For my application I am not using a fill dish.

For gravity feeding you can place a larger fitting such as a PVC elbow in the tank and allow your hose to rest in this when filling, not making a secured connection as this would then be pressurized.

You would still need to vent the tank, this can be as easy as placing a fitting with a screen secured over it. Be aware that if you overfill the tank the excess water will exit the vent fitting, placing the vent fitting overflow to an outside location is recommended.

Be sure to screen over the vent fitting overflow to prevent anything from entering the tank. Do not over-tighten fittings as damage will occur. Examples of Fittings you could use, depending on your application.

Can I hook more than one tank together?

Yes, sometimes this is called to "daisy chain" the tanks together. You will need to check with a certified plumber to see what fittings and set-up will work best for your unit, remember to vent each tank.










I bought a fitting from my local hardware store and it won't fit.

Be sure you are using NPT fittings and getting the correct sizes. Do not over-tighten fittings as damage will occur. It is recommend to use plastic fittings with the plastic fittings installed in the tank to prevent damage to the fitting threads.




National Pipe Threads (NPT)
Pipe sizes do refer to physical dimensions, but the plumbing industry standard for the sizes of pipe is not always as straight-forward as measuring the pipe. Measuring the pipe will oftentimes mislead you into choosing the wrong pipe, so do take care. The "pipe thread size" as shown in column 3 of the table below is measured and based on the inside of the pipe. But, to actually determine the size of a pipe, the outside diameter of each pipe or fitting must be measured and compared to the table for size identification. For example, a 3/4" NPT pipe thread has an outside diameter of 1.050 inches. Each thread size has a defined number of threads per inch (TPI). The 3/4" NPT pipe thread has 14 threads per inch. Both the TPI (threads per inch) and OD (outside diameter) of the thread are required for positive identification of thread size because several sizes have the same TPI.

Male threads: Measure the outside diameter of the large portion of the thread at "A"; Find figure nearest this dimension in column 1 or 2 of chart. The dimension in column 3 will be your nominal pipe thread size.


Female Threads: Measure top diameter of thread at "B"; Find figure nearest this dimension in column 1 or 2 of chart. The dimension in column 3 will be your nominal pipe thread size.


Q."What does 'nominal' mean?"
A. Nominal is the term used to describe pipe and fitting measurements in plumbing. Nominal refers to the inside diameter of the pipe which varies by wall thickness of the pipe.

Q."Ok, so IPS pipe sizing isn't actually a dimension. So what about the fittings?"
A. Pipe fittings are "sized" by the "size" pipe they fit. So, for example, a 1/2" IPS fitting would fit 1/2" IPS pipe.


National Pipe Threads (NPT) have tapered threads. These are the most common threads used for general purposes. NPT threads are designed with a 60 degree thread angle, and are used for joining and sealing pipe to fittings in low pressure air or liquids and also mechanical applications. The tapered thread is 3/4" over one foot of length. Tapered threads are deeper at the end of the pipe and are increasingly shallower the further they are from the end of the pipe. The taper on the pipe only allows the pipe to screw inside the fitting until it is forced to stop because of the taper. The distance the pipe can be screwed into the fitting is specified by the ANSI standard. After tightening with a wrench the threads may have slight spaces between the pipe and fitting which could cause a leak so a pipe sealant must be used to ensure any gaps are filled.

The Dry-seal thread (NPTF) also have tapered threads. NPTF threads are used when the application is such that pipe sealing compounds may fail due to higher heat or pressure than normal NPT threads can withstand. The threads are designed to seal mechanically by slightly, but sufficiently, crushing the threads when tightened with a wrench. This allows for joining the pipe and fitting without sealants.

The NPT and NPTF threads can be interchanged if sealants such as PTFE tape or suitable pipe joint compounds are used. None of the other thread standards are fully interchangeable (GHT, NST, BSPT, NPSI, etc.) Female NPT threads can be designated as "FPT" or "FIP" and male NPT threads can be designated as "MPT" or "MIP".

National Standard Free-Fitting Straight Mechanical Pipe Threads (NPSM) have straight threads which are only used for joining. A washer or gasket is needed to seal this type of threaded connection.

There are also three less common thread types used in the plumbing industry. The Garden Hose Thread (GHT) and the Fire Hose Thread (NST) have coarse threads. The seal is made with a gasket or washer and are used mainly for attaching (joining) hoses to valves quickly, without the use of a wrench. The British Standard Taper Pipe Thread (BSPT) has a 55 degree thread angle (NPT are 60 degree) and is used internationally as a standard thread for joining steel pipes.







~ Installing & Bracing ~






Can I install the tank under the trailer?

Tanks can be installed inside or outside of unit, for food vendors verify requirements before purchasing as some areas do not allow tanks to be outside of the unit and others do not allow the tank to be inside of the unit.
Be sure to Sanitize Tank before installing.

All tanks must be braced and secured to prevent any movement of the tank while in transit and to prevent possibility of tank tipping or falling.
Due to the manufacturing process all the tanks especially the larger in size will have a bowing to the walls, when the tank is filled the tank will expand out removing the inward bow, we recommend laying all tanks on a level surface (this can be angled to help with drainage) and bracing the tanks. For larger tanks it is recommended to brace all side walls with plywood or metal, we do not recommend using ratchet straps on the tanks alone as this is a large amount of weight on a thin strip and may cause cutting into the tank. For tanks placed outside it is also recommend to enclose tanks using sheet metal / plywood or some other type of weather proof material to prevent damage from road debris and speed bumps, be sure to check your clearance before ordering.

Brackets or Strap Systems Due to the variety of installations we do not carry brackets or bracing systems.
