How do you guys deal with expansion of pex in your basements? I have over 2ft of expansion over approx 30 ft. of pex line in my basement going to heat exchanger. The total line in 260ft. My original set up leaked on start up this year and I made some modifications and they seem to be working.

My line from OWB to house is 160 ft. Inside the house it runs another 15 or 20 ft and there are a couple of lazy 90 deg bends that allow for expansion and contraction.
-
If I don't want it to move I fasten it down before we fire the furnace up.
-
Where does the expansion occur if you fasten it down? In the buried section of the PEX?
-
I assume so, I just know if I attach it securely in the basement it doesn't expand into there.

When I installed my furnace, I had prior knowledge of the pex expansion issue. With this in mind, I decided to leave a service loop on the wall so that it could expand there. This way the expansion didn't torque a fitting or bind up in an area that couldn't handle it.
