The Covered Pool
As stated above, the covered dormant pool offers protection from debris and additional safety depending on the cover installed. It is usually recommended to do a final filter cleaning or backwash before winterizing. Depending upon the type of pool, usually the water level is lowered below the skimmers and skimmer freeze protection is added. Following this, the pump, filter, and heater (if present) are drained and the lines are winterized. The cover is then installed per the manufacturer’s instructions.
