RV waste tanks are made in a range of shapes, sizes, and valve arrangements. Please have information on the size, dimensions and 3 inch outlet valve handy of your existing tank. We can supply over 75 different sizes, dimensions and outlet valve placements. 8 common waste tanks with manufacturer's numbers are illustrated at this link to RV waste tank replacements. After viewing these drawings, simply close the 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.
