Tim,

Looks like you used PVC on your rerun of H2O lines. I just ripped out all of the old (split & coroded) copper. Any words of wisdom?

Secondly, has anyone figured out why A/S would install the furnace directly under the kitchen sink? Mine is completed rusted out. I hope to remove next week and try to salvage it!

I used CPVC. It's made for potable hot and cold water.

The common replacment is to use PEX so you should look into that as an option.

I chose CPVC because it was locally available, cheaper than PEX, and the various joints, 90's, t's etc... are smaller. I also like the idea of glued joints as opposed to crimp or compression.

So far it has worked great. No problems.

Good idea to change out all of your supply lines at once. Sure does take the worry out of having leaks on the road

I believe it to be significant that no manufacturer of RVs use CPVC for fresh water plumbing. Most, perhaps all use PEX.

Yep, this ALWAYS comes up when CPVC is mentioned. That's why the first thing I said was:

Okay I'm game, What are the Pro's and Cons.

PEX-
Pro's- Flexibility, install time, maximize space
Con's-Cost, clamp connections, pinched lines (potential)

CPVC-
Pro's- Cost, sealed connections
Con's- Install time, larger space required

Missed one...CPVC will crack wide open if frozen, PEX will take a light freeze

For fittings for the PEX you can't beat SharkBite Fittings and they will work on copper to PEX too for those pesky repairs.

I bought a REALLY nice used/refurbished one from Colaw's RV Salvage for $275.00 Works great and I now have the piezo lighter on it. I try to run it once a month to check on it. So far it has worked flawlessly.
