Options For A Black Tank Leaking Near The Discharge And Dump Valve
Question:
We have had an ongoing problem with our 3 2017 3760el bighorn whete the black tamk leaking all over the underbelly. Its been repaired at least 6 times only making the problem worse. We ended up getting a new tank including fittings washers rubber gaskets and new dump valve. The repair was done and im yold i needed to let the glue for the piping connections dry few hours before filling the tank. I had a question regarding the glue used which was oatley purple. I was understanding you had to use 2 different types of glue for abs, pvc and cpvc. The picyure shows 2 different colors of pipe. White piece attached to dump valve and abs to the tank. Was this job done correctly?

Helpful Expert Reply:
Using PVC (white pipe) between ABS fittings (black) is not usually an optimal setup on a trailer because of the movement during transport and colder temperatures can cause PVC to break more easily.
The Oatey Purple is a PVC primer and not a glue so it wouldn't adhere correctly. Using a green transition glue as well as the purple primer on the PVC pipe could have worked however. Ideally they should have used black ABS pipe between the fittings and used ABS cement like LaSalle Bristol ABS Solvent Cement # 3447530889.
