plumbing

I'm curious why you'd want to do that. PEX plumbing is much more flexible that PVC, and is the preferred material for RV plumbing.

Its not the easiest thing to do but if the TT is open and everything is easy to get at it should work ok with some trial and error. While you are at it go ahead and replace the water lines with pex and put shut offs on every fixture you will be happy you did.

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.

actually i through pvc would be better than the lines that came with my tt, so i guess i leave it the way it came from the factory. thanks for your advice .

2008 Passport?

If so it came with PEX
PEX is used not only in RVs but residential/commercial plumbing.

PEX (or crosslinked polyethylene) is part of a water supply piping system that has several advantages over metal pipe (copper, iron, lead) or rigid plastic pipe (PVC, CPVC, ABS) systems. It is flexible, resistant to scale and chlorine.
PEX is much more resistant to freeze-breakage than copper or rigid plastic pipe.

Wise decision.

True, very wise.

Somebody paid a fortune to send their little boy or girl to engineering school to learn how to use the best material, for the best job, creating satisfaction for the consumer and a profit for the company and you want to re-invent the wheel.

I always say, "GO FOR IT"

but don't come complaining about your results.

Mistakes deserve sympathy, big mistakes deserve a camera and You tube.

You could consider CPVC , regular PVC isn't hot water rated .

If you have Pex , going to PVC or cpvc is going backwards in time.

Would be nice if we all had those nice brass elbows and T fittings instead of the flair-it and other cheap plastic stuff.

Still probably not worth replacing the fittings unless a problem develops.
