Terrified customer
After my temperature sensor said it was 28° and oh hey let’s turn on the freeze protection on even though we are all sweating in 99° temps this July. I decided to buy a new sensor. Seriously terrified to do this. Oh so easy to do and yes it works. I’ve earned my pool girl tool belt!! I’m so proud lol
Thanks Pool Guy Supply for having a great price on this.
