I have an in ground pool and we are supposed to reach temps in the single digits. Do I need to do anything to protect my equipment when I have the aqua link system with freeze protect mode? Will it handle single digit temps?
I’d try heat tape (or sometimes called heat cable). It’s flexible so you can wrap it around different size pipes, etc.
You can just plug it in when you need it or add a thermostat that turns it on automatically when temperatures reach a certain point.
The specifications for this one says it’s good down to -40F.
In my area pealing poles the round fence posts left over from making veneer ate painted black and floated in the pool to keep ice from damaging the pool, keeping the pump room warm usually protects the pump and filter with no pressurized or trapped water we have never had our pipes break due to freezing, before someone suggested the pealing poles painted black I used to use a large thermal blanket but snow and ice on top ruined them fairly quickly, I have been using the same poles for 8 years and have had no tile damage since doing this. But our negative F temps only last for a few days and it warms up in the day time usually.
