Forum Title: Copper vs Pex
I am renovating bathrooms in my house and wish to use PEX (expanding kind). I have the materials already. My question is this... There seems to be differing opinions on running PEX from the shower valve to the shower head and tub spout. Some say why not go with PEX and others say ALWAYS use copper here, PEX is OK to supply the valve. What is the consensus on this and what is the rationale?

Feed 3/4 as close as you can to the shower control, reduce to 1/2. Pex is fine for your standard shower (no body sprays or wands).

Most valve manufacturers specify to NOT use PEX to the tubspout.

i would take it a step further. no pex on the shower riser either. why?????? down the road, when mr homeowner wants to change out the spout or shower head. try's to remove the old. and does nothing but twist off the plastic tubing. also. the pex is a smaller id of pipe than copper on a spout or head you want volume of water pexhttp://screencast.com/t/NVUpUnSrdPzZ copperhttp://screencast.com/t/6bT6cal3B4
