Leaky Thetford Outlet Connection--How to fix?
I have a 1998 31' Excella in generally very good condition (I purchased it about 6 months ago).
I've noticed that the drain hose that came with it will need to be replaced sooner than later--it has some pin prick holes (I can hear air rushing in and out of it).
I've also observed very minor leaking out the outlet connection. The whole thing connects to a Y or something, b/c I drain both black and grey at the some outlet.
The outlet connection and hose bayonet appear to be original Thetford parts. I purchased a new Rhino hose but the bayonet did not fit the outlet connection on the trailer (the connection was too big and the bayonet simply didn't fit onto it--i.e., the bayonet is too small to go over the outlet connection).
The outside of the outlet is 3 and 3/4" (not counting the pegs for bayonet). The inside is 3".
Can I use a coupler directly on the inside and then a new outlet with pegs so I can adapt for a new Rhino or other hose?
I tried the Thetford hose system (Smart Drain or something like that), but it was too small for the outlet too.
If I try the coupler should I just glue it with proper adhesives (looks like the outlet pipe is ABS, but I'll check with Airstream before I do anything)...
