MAINTAIN PROPER WATER LEVEL IN YOUR POOL
Your water should be maintained at the center of the tile (vertically) or halfway up the skimmer opening. This is the number one cause of freeze
damage on pools. If the pump loses prime, then the water stops moving in the equipment and everything can freeze.The evaporation rate increases as the temperature decreases. The evaporation rate is directly correlated to the temp differential between the pool water and the air.
MAKE SURE YOUR POOL IS RUNNING IN FREEZING WEATHER
Freeze protection can fail. Make sure all your pumps come on (except your pool sweep pump) when the weather drops below freezing. On variable
speed pumps, they will cycle on and off if you are depending on the freeze protection on the pump. If the temp gets really low (below 15) then turn the pump on manually and let it run 24/7 at a speed of at least 2000 RPM. If you see your flow diminished, your filter might need to be backwashed. If you backwash, make sure your backwash line is not blocked by ice or it could blow up the filter.
Normally, keeping the pump running should keep you out of danger, but this is an extreme freeze that we have not seen in DFW in many years. A tarp will keep the wind from supercooling your equipment and will preserve a little ground heat.
