P-trap repair (1999 RT 190V)
I recently suffered a broken shower p-trap on my 1999 Roadtrek 190 Versatile and discovered to my dismay that it's not a standard plumbing part. Not only are the female threaded hubs on the u-bend side rather than the pipe side, the p-trap itself is 1-1/4" instead of the standard 1-1/2".
To make a long story short, I cut off the busted hub, bought a new female threaded connector to attach to the shower drain, and joined it to the p-trap with a rubber Fernco coupler. The rubber coupler was just big enough to stretch over the end of the p-trap. I also had to file the raised lettering off the p-trap to allow it to seal properly.
Just thought I'd post this fix, since it seems these oddball p-traps are fairly common especially on older RVs.
