My pool is open 12 months per year, but I live in a part of Florida that gets some very cold nights in January and February.
On freezing nights I keep the pump running, but want to add some protection to the 2 1/2 inch diameter water pipes that supply the pool. I have seen pipe sleeve at HD and Lowes, but only for smaller PVC pipe. It is a spongy type insulation material.
So, how do you protect the larger pool supply pipes from cold weather? What do you use?
