I have a 30 ft keystone passport i want to re-plumb my tt with pvc pipe i was wondering if anyone has done that before and if so how hard is it to do . Taking in consideration i am not a plumber.
Here's another vote for keeping the PEX in there. It's nearly trouble free, stretches more than PVC (in case of light freeze) and increases RV allowable water pressure to 60 PSI rather than the older 40 PSI.
