On our last trip I noticed the 4 year old Thetford toilet was failing. When the water pump was on water would continuously flow into the bowl, potentially overflowing. We got by OK for a couple of days by just shutting off the pump but it was a PITA.
I assumed the internal valve had failed and bought a repair kit several weeks ago. Day before yesterday I finally got around to installing the new valve as we are headed out on Monday to Patagonia Lake for a few days. The new valve kit went in easily enough but I failed to notice that the male threads on the water line inlet were stripped. Probably overtightened at some point in the past.
I tried to repair them by chasing the threads with a female coupler and did manage to clean them up a bit but they still made me nervous. At this point I just bit the proverbial bullet and bought a new Dometic 310 series that was on sale at CW for $170.
Installed it successfully today but did have to overcome a couple of challenges. The water inlet on the new Dometic was 3" lower than the original Thetford. Nexus uses the Pex water lines and while they are top of the line in terms of quality/durability when it comes to flexibility... not so much.
I bought a couple of fittings at Ace Hardware - a threaded male with a half inch hose barb that went into the feed line and a threaded female with half inch hose barb that attached to the toilet. By aligning and connecting them using a 2' piece of half inch PVC tubing looped to give a clean connection at each end I was able to make it all work.
A double wrap of Teflon Tape on each fitting and SS hose clamps secured both connections without any leaks. Most of the connecting was done by Braille back behind the toilet but by sanding down the hose barbs, adding a squirt of teflon spray and a fair amount of profanity (I was working alone), managed to seat the hose barbs securely .
Wasn't much fun but we now have a nice new (as in better), toilet and saved about $150 on the install.
