Compression fitting in wall and water heater connection

mtnbkr · Sep 24, 2007, 12:56 PM

So from what I gather, it sounds like it's not recommended for in wall application. I guess I don't really need it to be in wall, and can just leave it unfinished. Just trying to hear what people think. Any code problems in Maryland?

Now for the water heater. What I'm trying to do is move my hot water heater about 4 feet over from where it currently is. I currently have all sweat connections w/ copper. I'm moving the hot water heater closer to where the copper is coming from, so will need to cut it down (does that make sense...I won't need to extend it out or anything). Therefore, what I'm thinking is I'll cut off about 4 feet, roughly the distance I want to move, then put compression to 3/4 cpvc adapters on. I don't want to make any sweat connections, since I've never done that before. Then I was going to run CPVC down from the ceiling where the copper is, down close to the water heater. From there, solvent on some npt threads (using roughly 2 wraps of teflon tape...right?), then get some flexible water heater connectors to go from there to the heater, then back out. Anything wrong with this?

Thanks.

With propane you can throttle the flame with the valve.

I've never soft soldered pipe with MAPP. I've silver soldered with MAPP and Oxygen and Acetelene and Oxygen and MAPP.

I've done some quartz glass work with Oxygen/Hydrogen.

My vote is for Propane.

Reminder: Don't solder anywhere near the inlet/outlet of the water heater. There are plastic inserts that will be damaged.

The mapp is mighty expensive at my local stores. I might end up with propane...still not 100% decided.

Thanks for the tip on the inlet/outlet for the water heater. I read that on another forum as well.
