Terry plumbing questions

[flyweed]

HI all. We have a 2004 Fleetwood Terry travel trailer. Anyway, some red squirrels got up above the grey water tank this winter, chewed enough of the floor away and nested in a cupboard drawer above the grey water tank. Anyway....while chewing the hole, they managed to chew a hole into the grey water waste line that goes from the bathroom sink and shower drain, and down into the top of the grey water tank..now..the straight piece of PVC will be easy to replace,but they also chewed a portion of the "T" that the upper side connects to the air vent in the roof, and the lower portion leads down into the grey water tank is...SO, I'll need to replace this T as well. Only problem is a portion of the T is down past floor level. I have no idea is this pipe is just a "slip" fitting into the greywater tank, or how it's connect, so I thought about dropping the grey water tank, but I don't want to do that, as I don't know how the drains are connected....any idea on how to replace these pieces would be MOST welcome.

Thanks

Westend..thanks for the reply. That's what I figured, either dropping the tank, which I DON'T want to do if at all possible. I guess I'll do the "cut a larger access door" method around the pipe into the floor, so I can get my hands in there to work. Repair the pipe connections, and then replace the floor with maybe some sheetmetal, so the WON'T be able to chew in that way again.

You'll need to cut the pipe past the chewed pieces. You can then use new pieces, glued in, or use a straight piece of pipe with a repair coupling and establish a new configuration. Either way, you will most likely have to drop the tank or cut the floor to accomplish the work. You may get lucky and find a slip fitting into the top of the tank and be able to push pipes around to glue up new pipe.

Remember to save a few choice words for vermin.
