Securing PEX to Wood ?

Hello,

A plumber put a 20' run of PEX that had been supported by some wood cross beams that were recently removed. I now need to secure this pipe and wanted to know whether it's appropriate to secure PEX to wood using a copper van hanger? Given the location of the pipe and the wood, this should work well. Is there any issue with using a copper plated clamp with PEX? Thanks in advance.

Welcome to the forums. Use Sharkbite talon clips. Made for this application. I would not use a metal strap. SharkBite 1/2 in. x 3/4 in. Plastic Talon Clamps (10-Pack)-23220 at The Home Depot

Why not? I'm assuming there is no movement of the pex along the metal.

PEX expands and contracts greatly as it's temperature changes. This movement over metal will eventually cut through PEX. Trust me, I learned that one the hard way. The plastic hangers designed for PEX are very inexpensive and easy to use so there's really no excuse not to.

Thank you for the reply. I saw those, I need something I can screw into the wood as there is really no room to hammer anything. It's a very tight space and there is copper pipe that's in close proximity. Are there are other styles of PEX clamps.

Would this work? It has rubber: http://www.elecdirect.com/images/pag...ableClamps.jpg

Yes, you can use those clamps or you can pull the nail out of the plastic PEX clamps and replace with a screw.

I think I missed something ? Hot Water or Cold Water ? I have never used PEX . Is it approved for HW ?

If for HW , are you going to insulate it ? If so , get a large enough strap / clamp to accomidate the insulation .

I have been using

Plastic Hanger Strap | Pipe Support | Oatey

to hang my new HW lines + the insulation . And an appropriate screw for the floor joists .

God bless

Yes Pex is good for both hot and cold water. Much easier to use than copper, cpvc, or other traditional materials. Insulating the Pex would require a different clamp, and what you show is viable.

Thanks , I will remember that . Is there a different " color " PEX for HW or is it the same as for CW ?

If it is like the old Quest pipe , the price of the fittings is where they " got you " ? I think they took it off the market ?

I have been using copper for my project .

God bless

Pex comes on opaque white, red (hot) and blue (cold). Totally different from polybutelyne, or Quest.
