Recently we had an instance where the overnight temperature was forecast to drop below freezing. Rarely does this occur here in the “Sunshine” state, but when it does, it always triggers calls from customers asking what should they do to safeguard their pool equipment.
Fortunately, the temperature here rarely stays below 32 degrees for more than an hour, so the water in the pipes probably won’t freeze. The question still remains, at what point could it freeze? I don’t have a definitive answer, so when in doubt, I suggest you do what I do here at my home – simply run your pool pump overnight. Moving water will not freeze as readily as standing water, reducing the chance of damage to your equipment.
