I finally bit the bullet this weekend. I heated up the old tee and took it out, no problem. Somehow I was able to get enough indirect heat on the new copper fitting (from the extremely small access...

I have two fifties in series for my hot water.

I think I will try to change this small section of pipe, just to be safe.

I will try to get to the tee in the wall without disturbing the adjacent...

Did I mention the shower will be running 7.5 GPM (three heads)? Any change in opinion?

So, it'll work relatively the same, but.....it'll be loud as all get out, huh?

If I put split foam insulation around the 1/2" part and pack the stud cavity with fiberglass will the velocity noise...

Okay heres the setup:

3/4 supply......~1 ft. of 1/2".......~15 ft. of 3/4"........tee 1/2" to thermo. shower valve and 1/2" to tub filler.

This is just the hot, the cold supply comes further...

3/4 supply, tee 1/2 to thermo, 1/2 to diverter, 1/2 to all stubs...

let me...

Do you think that the smaller i.d. of PEX will have have a direct effect on the pressure or flow I get from any given head? (1/2" PEX vs. 1/2" copper). Here is a crude sketch. No more than 2...

Thanks for the prompt reply Racer!

I have to use two exterior walls for this shower and just for my own piece of mind (of course I will insulate excessively) I would like the added freeze...

Anyone ever plumb a custom shower (thermostatic, diverter, shower head, body sprays, hand-held) with PEX? Pros? Cons?

If you have, how did you stub out the body spray heads in the balancing...

What about Danze? I have a whole house full of Danze fixtures with no problems...yet. (knock, knock....ouch;) ) They seem to be well built (all brass, no plastic, ceramic valves, etc.) Just...
