Preparation & Installation

3" ABS Hub used in Class A Customs Black Water Tanks

Due to the size, this can be used for Human Waste or Shower - Dish Washing - Hand Washing Tank.

Do Not over-tighten fittings damage will occur

Dump valves do not hook directly to the 3" ABS fitting, from the outlet run PVC or ABS piping to the outside of the trailer, a dump valve is added to the piping.

Please note that Class A Customs Waste Water Tanks ABS fittings are installed during the manufacturing process, this will be difficult to remove if you are needing to replace this item.

We recommend seeking a certified technician for removal and installation of ABS fitting.

Class A Customs uses a speciality adhesive during installation, we do not sell this. You will need to do an online search for available ABS/PVC adhesives to use if replacing the outlet fitting.

EXAMPLE ONLY

&amp;lt;br>

Installed Outlet Options

3” ABS Female Pipe - outlet can not be moved

1.5" ABS Female Pipe - outlet can not be moved - Due to the smaller outlet this tank is for dirty water from shower, handwashing, dish-washing - DO NOT use for human waste

Connecting Pipe & Dump Valve

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.

Pipe is connected to the ABS installed fitting in the tank with glue. You do not need to tighten the clamp that is on the ABS Fitting, this is used when the ABS fitting is installed into the tank and does not help secure your piping, over-tightening this clamp will damage ABS fitting and tank

Dump Valves

Dump Valves 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.

We do not sell glues, example only Oatey 4-fl oz Green PVC/Abs Transition Cement

Inlet & Vent Installation

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.

Grommets are not food safe so can only be used for Gray or Waste Water use they are available in sizes 1.5" and 3", no adhesives are needed for use.

Uniseal Fittings 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.

Use correct size hole saw bit in order to drill a hole in the tank, smooth tank edges, and place Grommet or Uniseal in hole. Piping is then placed into fitting with no glues or adhesives necessary.

Mounting & Bracing

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.

Brackets or Strap Systems 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.

Water Tank Monitor System

RV Monitor Panels 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.

Installation Help Step-by-Step

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 wiring diagram for wire gauges ( 20 AWG / 14 AWG)
