frozen-pool-equipmentThis was one of the worst winters in recent history – here in Chicago, we’ve had nearly 70 inches of snow, with an average temperature of 18.8 degrees. According to the Tribune, this is the third worst winter ever recorded!

Cold winters like this have the unfortunate side effect of freeze damage to unwinterized pool pipes and equipment.

Underground pipes rarely freeze if they are deep enough, however, this winter had more days below freezing than any year on record! Every consecutive day of freezing cold increases the depth of permafrost in the soil, and can reach even the deepest pipes. When pipes are more than half full of water, they crack, usually in a tell-tale spider web fashion.

If you prime up the pump this spring, and notice water pouring out of your heater, first check that the drain plugs are tightly in place and the pressure switch is connected. If water still pours out under the heater, remove the side access plates, if you cannot see a visible crack.

The repair involves removing the heater top, and side plates to gain access to the header bolts. Remove and replace, with new header gaskets.


In many cases, pool filter tanks can withstand the pressure of frozen water, and the external valve will crack first, allowing the tank to drain. In the case of top mounted sand filters, the valve can pop off the top, cracking the tank flange.

Filter tanks, flanges or clamp bands that show any sign of leaking or damage should be replaced immediately, for safety reasons.


Pool pumps typically have two drain plugs, one for the basket pot, and one for the volute. A cracked pool pump may not be immediately evident, due to small cracks in thick plastic, or in other cases, you can spot a cracked pump housing right away.frozen-pool-pump

In most cases, a frozen pool pump doesn’t need complete replacement, but repair to one or two pump parts. The usual repair for a frozen pump is to replace either the hair & lint pot, or the volute – the impeller and other pump parts are not usually harmed.
