'm curious ... for those of you who installed an RV toilet shutoff valve in your rig - why did you do it?
So far none of you have reported leaks from your RV toilet fresh water inlet valves due to them developing hairline cracks in the plastic material. Am I the only one to notice this manufacturing/design flaw?
------------------
That's exactly what happened when I decided to replace the toilet. Hairline cracks can develop by overtightening the fitting that goes into toilet. It could create stress on the threaded port opening.
It doesn't matter whether you are using metal or plastic fitting. Over a period of time plastic shrink. It's because of this "phenomenon" that things like this develop.
I installed a shutoff valve because the DW wanted a "bidet" like we have at home. Thetford calls it "extended hose rinse" feature or something like it. It tees off after the valve before going into the toilet port fitting.
Picture a hose rinse in your kitchen sink. European hotels have this in all bathrooms.
