I have a cracked coupler on the gray water drain pipe which threads under the tub and towards the gray water valve and outside. It won’t stop leaking. My RV mechanic here in California cannot find the part because he doesn’t have a part number. He called the manufacturer and they’re not calling him back. He tried ordering two parts So far and all were wrong. Would anyone know which part I’m talking about? It’s a 2019 Riverside Whitewater Retro 189r.   He says it’s different because it has a swivel on one side that attaches to a P drain, which he’s never seen before. He can remove it as a unit and make it so it won’t leak, but I’m afraid of that. Can anyone help?

Ps. I should clarify, the coupler  is under the tub, inside the trailer, and before the gray water drain valve outside.

Thanks. I finally got thru and they basically told me they don’t have a specific part number, that people buy some type of rubber boot to fix the problem I have. Hmmmmm. Then they tell me that my model and year had these issues, and the P trap they use now is different. Hence, my mechanic would have to add an extender to the newer P trap to stop my coupler from leaking. Huh?
