RV Waste Holding Tanks

RV Waste Holding Tanks Picture

RV Waste Holding Tank

RV waste holding tanks come in many different shapes, sizes, and valve arrangements.  When ordering your replacement motor home, travel trailer, or other RV Waste water or gray water holding tank, please make sure to have information handy on the size (gallons), dimensions (overall length, width and height ) and 3 inch dump valve location.

Drawings of two common ones with manufacturer's numbers are shown in this link to RV waste holding tanks.  A new window will open; therefore, simply close this new window to return here.

As these tanks are made of polyethylene plastic, the following products are not compatible: Sealants, pipe dope, greases, petroleum jellies, glues or other adhesives. Required plumbing include a 3" inlet and 1.5" or 2" vent in the highest part of the tank. You must drill these holes in the proper places to suit your plumbing situation. Installation of the piping is most easily accomplished by use of rubber grommets as shown.

Part #88-1259 - 3" rubber grommet

Part #88-1257 - 1.5" rubber grommet

The example RV waste holding tanks shown in the above link are listed below:

PPL Product #  Manufacturers #  Gallons  Overall Dimensions  Valve Location
23726  H086  27  9" x 19 7/8" x 56 1/2"  end center

Also you should have the existing dimensions: length, width, and height and you should also know the position of the 3" discharge valve. Is it on the middle end, middle side, left end, right end, left side, right side, etc.? It is suggested that you make a sketch and put detailed dimensions on the drawing similar to the drawings of these sample rv waste water tanks. (Note that the drawing does not have to be neat as long as the information is noted. Fax your ugly drawing to PPL's RV Parts Superstore at 713-995-8697. Include your name and phone number so that we can help you find a replacement tank. For faster service, simply call the Parts Superstore at 1-800-755-4775 with needed information and we will work hard to find a suitable replacement for you.

Even though we stock a large number of different replacement units, installation of the product might require creating inlets and in some cases redoing the plumbing to properly connect.
