pex pipe winter

PEX pipe can freeze, but its flexibility means it typically expands rather than cracks — unlike copper or rigid PVC. The bigger risk in LA isn’t freezing: it’s when a PEX fitting or connection fails during a cold snap, releasing water inside a wall cavity. This guide covers the real freeze risk for LA homes, which fittings are most vulnerable, how to insulate exposed pipes, and what to do when water damage has already occurred. Call (818) 336-1800.
