allow you to monitor the amount of fluid in your water and waste tanks
along with the battery power level. Typically only one monitor panel (2
tank or 3 tank) is needed per vehicle/unit and 4 Probes per tank.
To check fluid levels, press and hold the button designated for the tank and read the level indicators on the panel. Sometimes, residue on the sides of a tank, or water with a low mineral content will give a false reading.

Check the levels occasionally when you are sure of a tank’s contents and compare it to the reading on the monitor panel.
4 Probes per tank needed
3/8" drill bit needed Measure
and mark installation points before drilling. After drilling be sure to
remove any burs from hole. Do not over-tighten probes.
Tank
harnesses included with monitor panel. Customer will need to provide
the extra wiring to run from the tank harness to the monitor panel. View

NSF LOGO
Class A Customs was required to remove the NSF logo from all water tanks 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 for 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 we make, even though they are made using the same NSF Certified Materials, made in the same process, made on the same machine, we would need to pay to use the logo on each item every year.
All of Class A Customs Fresh/Gray water tanks are manufactured using DOW NSF International NSF/ANSI Std 61 approved Medium Density Polyethylene (MDPE) Resin Because Class A Customs was verified to used and continues to use NSF Certified Materials to build our tanks we are allow to link directly to the NSF website materials page and are allowed to state the tanks are made from NSF Certified Materials.

Ask your local Health Department to provide you with a list of water tank manufacturers that have the NSF logo built into the water tank.
To see the tanks in an easier format with measurements and fittings view our Water Tank List (located at the top of each page).
Can I get an NSF logo on my tank?
No. Customer say they will pay to have the logo in a tank however, this would require a mold change, an inspection fee for the specific tank and a yearly inspection fee due to the mold of the tank being changed.

NO INLET & NO VENT
Class
A Customs Waste Water Tanks only come with the ABS outlet installed,
the end user will determine where the inlet and vent will need to be
placed and install (parts are not included). End user will need to determine size of grommets/Uniseal to be used based on piping and/or toilet flange pipe size.

are available in sizes 1.5" and 3", no adhesives are needed for use, can be used with hose clamp.
are food safe and can be used for Fresh, Gray, or Waste Water use, they
are available in size .5" to 3", no adhesives are needed for use.
INSTALLED OUTLET
Outlet can not be moved on the tanks.
We sell ABS Outlets that you can replace a damaged Outlet or change an outlet if desired.
3” ABS Female Pipe
1.5" ABS Female Pipe
Due to the smaller outlet a 1.5" ABS is typically used for dirty water from shower, handwashing, dish-washing, but not human waste.
You can use a 3" ABS Outlet and reduce it down to a 1.5" to use a 1.5" pipe.
do not
hook directly to the ABS fittings, the ABS Outlets are female fittings
and the dump valves are also female fittings, you will need a pipe to
fit inside of the outlet and dump valve in order to make the connection.
From the ABS outlet that is installed in the tank run PVC Pipe or ABS Pipe to the outside of the trailer, a dump valve is added to the piping.
We do not sell glues, example only Oatey 4-fl oz Green PVC/Abs Transition Cement
MOUNTING & BRACING
How do you brace the tanks?
Do you sell mounting straps?
Do you sell mounting brackets?
Some of the Class A Customs Waste Water Tanks are built with a "lip" on the tank. Tanks can be hung by this lip, it is recommended to make a shelf to slide the tank lip into.
You will need to brace the tank on all sides to prevent movement of the tank.
Due to the variety of installations we do not carry brackets or bracing systems. Do Not hang by ratchet strap, this is too thin and will not adequately support tank.

DO NOT HANG TANKS BY STRAPS - DO NOT HANG BY CLOTH STRAPS
Can I stack the water tanks on top of each other?
Can I put weight on the tanks?
No, do not place anything on the tanks, if you need to stack the tanks you will need a weight bearing shelf between them. A gallon of water weighs roughly 8.34 pounds, so a 40 gallon water tank when full is over 335 pounds in weight.
