Average tank thickness

Average tank thickness: .219 or 7/32" thick (just under 1/4")

All Class A Customs Water Tanks are one-piece seamless construction.

Rotatable

You can rotate the tank on any side, fitting placement will vary by tank, please be sure to view the tank photos provided.

*If you have fittings sitting on the floor you must recess or remove the floor for the fittings to sit in and piping/hoses to clear.

Installed Fittings See Photos

Two) 1.5" Female NPT Fitting - fitting is sealed to use remove membrane with razor knife

Two) .5" Female NPT Fitting - fitting is open

The fittings are not glued into the tanks, you will see residue from the installation process, this is where the tank and fitting melted together. Over time this will flake or crack, this in no way damages the tank or causes useage issues.

To add or repair fittings we sell Uniseal fittings, we do not sell spin weld fittings (fitting that are built into the tank).

We do not take orders for custom fitting placements or custom fitting sizes unless bulk ordering, 100 or more of each tank per order.

Can I get this tank with no fittings installed?

Yes, Class A Customs calls these Blank Tanks.

You will need to verify the lead time on Blank Tanks as we spin the fittings into our tanks as soon as they are made.

If we are currently making a tank we can get you a Blank Tank very quickly, shipping the next business day, however, if we are not currently making a tank it can take up-to several weeks to get a tank.

You can use the Contact Us Form to ask about lead times on the Blank Tanks.

When ordering a Blank Tank place the tank(s) you are needing in your cart and at check-out in the Customer Comments specify what tanks are to be Blank:

EXAMPLE:

Part # is a BLANK TANK

All Tanks Are BLANK

Manufacturing Vent Patch

Each tank will come with at least one permanently mounted patch, it is from the manufacturing process, this is not a fitting and does not unscrew and is water tight.

Non-Pressurized Tank

All tanks we carry must be vented, we carry Water Fill Dishes that allow you to fill the tank with fresh water and have a built-in vent (this is not used on a Gray Tank - Fresh Tank Only)

Bracing and Securing

Tank must be braced and supported, secure tanks to prevent movement.

Due to the variety of installations we do not carry brackets or bracing systems for our fresh/gray tanks

Sanatize Tank Before Use

Sanitize each tank prior to use to remove any debris from the manufacturing process. When tanks are manufactured they do not have the holes for the fittings so holes are drilled and fittings installed, the tanks will have shavings from drilling the holes. We do not flush the tanks due to wanting tanks to be completely new and unused.

Tanks are made in a warehouse so maybe dusty or scuffed, this does not effect the use or safety of the tank, wipe with a damp cloth to remove surface dust or scuffs.

Freshly made tanks may smell like plastic or a candle, but it will disappear over time with exposure to air and water.

If you have a strange taste in your water supply be sure you have used all food safe fittings and sealants or pipe tape, the tank will not give any taste to the water supply.

Water Temperature Tolerance

The temperature used during testing is 60 +/- 2°C (140 +/- 4 °F) and appears in NSF Listings Page as "D. Hot". This is intended to apply to product applications where the product is used for either cold (ambient temperatures) or hot water up to domestic hot temperatures.

You can not put boiling water into the tank, boiling water is 212 °F (100 °C)

The side of the tank is dented / bulged / bowed.

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.

Can you make me a Custom Water Tank?

Class A Customs can make a custom tank, however, this might be too expensive for most customers needing just one item, we recommend viewing all the tanks located on our Water Tank List to see if one of the tanks will fit your need.

The following is typical of making a new style tank.

You would need to prepay to have a mold made this ranges from $9,000 and up, lead time can be 8 weeks or more.

You would need to place a prepaid PO of a qty of tanks per month/per year, your sales associate would confirm this number, before the mold would be made.

You can use the Contact Us Form to provide the needed information on making a custom water tank.

Asked by: Mark D - 5/7/2024

A: All tanks Class A Customs manufactures must be vented (allow air in/out during use).
Do not make a sealed pressurized connection to the water tank (garden hose screwed to fitting that fills tank), tanks must be gravity filled.
We recommend using a gravity fill dish to fill the fresh water tanks, view below.

Preparation

Sanitize Tank Before Use

Tanks are made in a warehouse so maybe dusty or scuffed, this does not effect the use or safety of the tank, wipe with a damp cloth to remove surface dust or scuffs.

How do I sanitize my Waste or Gray Water Tank after use?

There are many products online that are to dedorize or sanatize your Waste and Gray tanks, you can search online for terms like "RV Holding Tank Treatment", "RV Tank Cleaner" and more.Online RV Forums are a great way to hear about tips and tricks others have used.Always remember to only use items that are safe for your materials and safe for the environment when dumping.

Installation & Plumbing
Non-Pressurized Tank all tanks we carry must be vented allowing air in and out when in use, Plumbing Examples
Do Not hook a garden hose directly to tank damage will occur, it is recommended to use a fill dish or other gravity process
Do Not over-tighten fittings as damage will occur.

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.

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

Class A Customs NSF Letter can be printed or forwarded to Health Department before purchasing any items, to verify that items will pass inspection. This is your responsibility.

Letter has all fresh/gray tank sizes, part #'s, measurements and fittings, along with material tank is made from.

Ask your inspector BEFORE purchasing any items - more information below

NFS Logo Requirements: Does the water tank have to have an NSF Logo? Class A Customs Tanks have NO NSF LOGO

Non-Pressurized Tank: All of Class A Customs water tanks must be vented and can not be pressurized.

Size Requirements: How many gallons is the fresh water tank required to be? How many gallons is the gray water tank required to be?

Shape Requirements: Does the bottom need to be slanted? Can I place the tank on a slanted surface as this would make the tank then slanted?

Fittings Requirements: Do you have requirement on the fittings sizes, placement or materials?

Filling Procedure Requirements: Does the fill dish for the fresh water tank need to have a lockable fill dish? Are there certain materials I must use?

Tank Placement Requirements: Does tank need to be mounted inside or outside of unit

Class A Customs Tanks that are white in color can be used for either Fresh or Gray Water use.

Class A Customs Tanks that are black in color are used to hold Human Waste and/or used water from handwashing sinks, dish sinks, and showers - they are NOT for fresh water use.

Why is there no NSF logo in the tank?

Can I get an NSF logo on my tank?

Class A Customs was required to remove the NSF logo from all water tanks we manufacture in June 2020, the tanks continue to be made from the same NSF Certified Materials, built in the same way, built on the same machines, and built in the same building here at Class A Customs.

The NSF Company does not allow end users of NSF Certified Materials to use the NSF logo unless each kind of item that is produced has a certification paid for each year. This would mean every style of tank Class A Customs makes, even though they are made using the same NSF Certified Materials and made using the same process, we would need to pay to use the logo on each item, every year at a substantial cost.

All Class A Customs Fresh/Gray Water Tanks are manufactured using

DOW NSF International NSF/ANSI Std 61 approved Medium Density Polyethylene (MDPE) Resin

Material is safe for Potable Water Materials – Class A Customs Fresh/Gray tanks are safe to be used for fresh or drinking water storage or gray water storage.

The temperature used during testing is 60 +/- 2°C (140 +/- 4 °F) and appears in Listings as "D. Hot". This is intended to apply to product applications where the product is used for either cold (ambient temperatures) or hot water up to domestic hot temperatures.

Because Class A Customs was verified to use and continues to use NSF Certified Materials to build our tanks,

Class A Customs is allowed to link directly to the NSF Website Materials Page and

Class A Customs is allowed to state the tanks are made from NSF Certified Materials.

The NSF associate Class A Customs was contacted by and worked with was;

25% Large Gray Tank Than Fresh: Multiply (fresh tank size) x 1.25 = Tank needed

50% Large Gray Tank Than Fresh: Multiply (fresh tank size) x 1.50 = Tank needed

I have only so much room how many gallons can I get in that space?
