So after reading through a bunch of posts i still have a few questions regarding closing the pool. This will be my first time doing it and everything seems pretty straight forward but still have a few questions.
1. When draining the pool, i have 2 skimmers and a main drain. Can put the sand filter on waste and close the 2 skimmer valves and just use the main drain to drop the water 4" below the returns?
2. When blowing out the lines, i plan to use a compressor attached to my pentair vs pump and add into the system at 10PSI using a craftsmen pancake compressor. What setting should the valve be set to? recirculate or backwash or filter?
3. Once i go along and cap each port as the water is blown out, how do you add anti freeze into the system? Do you do this after all the lines are blown? Uncap the skimmer and pour straight in How do get anti freeze in the returns? Assume you keep the main drain valve closed so water isn't reintroduced into the system. Just not sure about returns and skimmers.
