Plumbing advice for Crestline homeowners
Crestline plumbing lives and dies by winter prep. If your cabin sits empty through cold stretches, the safe move is to shut off and drain the system rather than trust a thermostat — a burst in an unoccupied cabin near Lake Gregory can run for days. If you use the cabin through winter, insulate exposed lines and keep minimum heat on.
Either way, know where your main shut-off is and have vulnerable runs insulated before the first hard freeze. We winterize on your schedule in the fall, which is far cheaper than a burst-pipe repair and cleanup after a January cold snap.
