noisey pex

Unknown

PEX-AL-PEX expands less... more like copper. Of course, you can get noise with copper too, so long runs still need expansion loops.

noisey pex

My brother has a HW BB set up in his home and is complaining about the Pex tubing clicking when the system heats and cools. He is using thin line baseboard. Is there a better way to run pipe or a diferent type of tubing that makes less noise? Is the nature of this thin line BB to be noisey? With the supply side pressed into the top of the aluminum extrusion and the return pressed into the bottom, I would wxpect it to "tick" by design. Any experiance with this stuff would be great Thanks.

BB not pex

I'd believe the BB is making noise - probably when the loop heats up and cools down (Fins expanding)

I've never heard PEX go "click/tink"

with Cooper if you use copper bell hangers and run the copper to close to the floor Joice. the copper will bang and crack when it heats up if you hang your copper just below the Joice and use plastic hangers you wont get any noise.

also if your holes are not lined up your baseboard fins could be pushing on the back of the baseboard backing and that may make noise. or if the hole is not lined up the pex could be pushed against the hole and that will make noise when it heats up

good luck

The Pex can rub on wood and make noise. This can happen if the holes in the wood are too small or the pipe was placed in such a way that the pex will rub on the wood.

these baseboards look like piece of base molding and have a pair of copper pipes pressed into channels in the back. No fins just a rather large aluminum extrusion. Thanks for the input.
