    Draining pool

    I have a spigot right above my pump, on the line between the pump and the filter. Can I use this to drain the pool? I need to lower my CYA.

    Thanks.

    Yes. That's why it's there.

    Be aware that if the main drain is not separately plumbed, you'll only be able to drain down to the skimmer, and then it will start sucking air and loseprime.

    Do I need to do anything on the simmer baskets so they don't suck air?

    If you have valves to shut off the skimmers and open the main drain, that's what you want to do. If you don't have a way to draw water only from the main drain, your best bet is to rent a submersible pump.

    Thanks. My only values are after the filter so I guess I will be using a sump pump.
