We have had no problems with the PVC piping other than it will shrink a little on the really cold night and cause some of the fittings to loosen. This only happens when the pumps haven't been running. Once the water is flowing they swell again and seal.

If the pumps stop they will melt on the contact point against the heaters. But that is not a bad thing. Easy fix and it lets the steam out.

We just take them down when the season changes.

>>Chris how does the PVC piping hold up? I worried about that when we put ours together and opted for the metal piping. Ours is set to run at an output of 120 degrees, of course losing temp as it flows through the pipes. I woried about how the pipe cement would do with prolonged temps like that. Plus, ours is set up set up permanent.
