Is braided supply hose as long-lasting and indestructible as PEX tubing?
This line into the toilet water supply valve will be pressurized whenever the water pump is turned ON which, overall, results in thousands of total hours of pressure in the line as the RV is used year after year. I assume that's the reason for PEX tubing in all of the RV's interior wall fresh water plumbing ... extremly long life under pressure. Is there any type of tubing more flexible than PEX that will hold up with this kind of use? Tubing price is almost no object for me in order to stop this irritating and trip-changing failure.
Adding a shutoff valve just for the toilet fresh water line is a must-have for us. However, valves themselves introduce a potential leakage point over time ... any suggestions on what small valve to use in the PEX or additional piece of flexible line that I install?
Millions of homes with multiple supply hoses and my trailer are left under pressure every day. If you're really paranoid about it get one of those "landlord" supply hoses that automatically shut if broken. I just buy the stainless braided hoses and have never had a problem. For a shutoff valve, I'd buy a brass ball valve.
Not knowing your plumbing skills, I'd suggest to visit the Sharkebite section at the big box store. It will probably have a valve in 1/2" to fit your pex pipe and it is a simple push onto the pipe. Make sure your cut pipe has no burrs.
