I am running a solar powered radiant floor using pex.
My pex says its rated at 100psi at 180f. how does it fail if temps go higher. Does it soften and blow out at swedged fittings? I have pex tubing starting maybe 30 feet from collectors (copper tubing to and from collectors), And the system runs at 10 psi. Could I be looking at problems if I have a power failure to pump? I have never read anything about pex failure at lower press with higher temps.
