Color Black in color so tank is easily identified as a waste tank

Made With Recycled Medium Density Polyethylene (MDPE) Resin - glues do not stick to this material and easily cleaned. - Because product is recycled and intended for waste use it is not tested for safety of drinking or gardening water supply.

Installed Outlet Options

3” ABS Female Pipe - outlet can not be moved

Inlet & Vent

Class A Customs Waste Water Tanks only come with the outlet the end user will determine where the inlet and vent will need to be placed and install.

Overall Measurements - See Photos

54.75" x 28.38" x 6.63"

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)

PLUMBING A GRAY WATER TANK

Gray Water Tanks are used to hold used water from handwashing sinks, dish sinks, and showers.

Black Water Tanks are used to hold Human Waste and/or used water from handwashing sinks, dish sinks, and showers.

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 can only be used for Waste or Gray Water use, do not use a black tank for fresh or drinking water.

If you want to place your tank directly under your sink or shower you can use a Uniseal Fitting to install a fitting directly where needed to allow the pipe to go into the tank.

Waste Water Tank Installed Outlet
Black Waste Tanks - 3” ABS Female Pipe - outlet can not be moved -
Gray Waste Tanks - 1.5" ABS Female Pipe - outlet can not be moved - smaller outlet this tank is for dirty water from shower, handwashing, dish-washing

The installed ABS outlet in Class A Customs water tanks uses a speciality adhesive and clamp for extra security.

It is highly recommended to get a tank with the correct ABS outlet size rather than trying to replace it. If you are needing to change out and ABS outlet you can seal it with and ABS/PVC adhesive and clamp, we do not have an adhesive we sell for this application.

Waste Water Tank Inlet & Vent

Class A Customs Black Water Tanks only come with the outlet fitting installed, the end user will determine where the inlet and vent will need to be placed and install.

Grommet (not food safe - waste tank use only) or Uniseal (food safe - fresh/gray/waste use) will secure inlet/vent pipe with no adhesives needed.

Use correct size hole saw bit (listed on item page) in order to drill a hole in the tank and place Grommet or Uniseal in hole, piping is then placed in fitting with no glues or adhesives necessary.

Do Not over-tighten fittings damage will occur.

Dump Valves are not connected directly to the Waste Tank ABS Outlet Fitting, the ABS Outlet Fittings are female fittings and the dump valves are also female fittings, they do not connect.

Use PVC or ABS pipe to connect to the 3" ABS Outlet Fitting installed on the waste tank, the dump valve is then connected to the pipe.

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

You will 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 Items to Vent Tanks - We do not sell these products they can be found online
Oatey® 1.5 in. NPT ABS In-Line Vent
Straight, Black Plastic Tank Vent

GROMMET INFORMATION

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, many customers use adhesive just as an added precaution.

3" Rubber Grommet used in Black Water Holding Tank

Hole Saw Needed 4"

1.5" Rubber Grommet used for Black Waste Tanks

Hole Saw Needed 2.5"

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.

After installation of grommet into tank hole, drain pipe goes inside tank grommet and is sealed.

Customer will measure and determine where inlet will be placed on Black Waste Tank.

Use correct size hole saw bit in order to drill a hole in the tank and place grommet in hole. Grommet will secure inlet pipe with no adhesives needed.

UNISEAL FITTINGS INFORMATION

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

Uniseal® Pipe-to-Tank Seals

Uniseal® is the world's best seal, and installing it is a simple process. After cutting a hole in the wall of a tank or other surfaces, the seal is inserted. Then the pipe is coated with a slippery detergent and pushed into the seal. The Du Pont Alcryn® is the key to the liquid-tight seal. When the pipe is pushed through the rubber-like Uniseal® from the outside, the inside Alcryn® wall becomes thin enough to allow the pipe to squeeze through and then forms a liquid-tight seal. The coefficient of friction with the plastic pipe is roughly three times higher than any other material, which allows it to create a better seal than with any other material.

• Alcryn® melt-processable rubber
• Long-lasting
• Resistant to acids, oils, greases, gasoline & sewage
• Withstands pressure & suction
• Withstands heat & cold
• Easy installation
• Reduced labor & material costs
• In static conditions, the seal is good up to 65 psi

*1 - Uniseals U025 and U0312, Uniseals U050 and U075, Uniseals U275 and U300, Uniseals U400 and U400-SDR35 require the same sizes of holes.

The difference is made up in the thickness of the Sarlink 4165 rubber.

*2 - Always measure the Outside Diameter (O.D.) of your pipe. This is the most important size to match into the Pipe O.D. hole size of the Uniseal to create your seal.

Instructions

1. Be sure to have recommended hole saw for selected fitting, check chart before cutting.
2. Using hole saw cut hole in wall, ensure that the hole is cut clean. Irregular holes could cause poor seating and possible leaks. File or sand the edges so there are no rough or sharp edges be sure to remove any remaining debris.
3. Insert the Uniseal with the wide surface facing out.
4. Make certain the pipe to be inserted is cut clean and square, file or sand the edges so there are no rough or sharp edges to cut the Uniseal surface.
5. Use liquid soap or Teflon lube on the pipe to be inserted. Insert the pipe into the Uniseal as far as needed to clear the inside of the seal by about 2".

6. Be sure to clean tank thoroughly prior to using removing any debris and lubricant residue.
