Thus far it has been a very mild fall/winter. With that being said, tonight we will get our first hard freeze with a projected low of 23 degrees. It is important that your pool equipment is prepared to handle the freeze.
Most pool equipment has been programmed so that the pumps are switched on by a freeze sensor when the ambient air temperature approaches freezing, but it is still important to make sure.
Following is what you need to be looking for:
Main pump—The main pump should definitely be operating when the temperature is freezing. This helps prevent damage to other components as well—such as the filter, heater, etc.
Booster pump (for automatic cleaners)—The booster pump does not need to be operating, since water from the main pump is circulating thru the booster pump.
Pumps for waterfalls, fountains, spa jets, etc.—Pumps for waterfalls, fountains, spa jets, etc. should either be operating or should be drained. Some might be on a freeze sensor, therefore if these pumps are drained the freeze sensors need to be deprogrammed.
Until temperatures reach the mid to high 20’s, it is unlikely that it is cold enough to do any damage.
If temperatures reach the single digits or will be under freezing for an extended period of time, oftentimes extra precautions must be taken. If that is the case, please contact us and we will be glad to advise you on how to avoid freeze damage.
