I need to drain a significant amount of water from my pool to lower the cya. I do don't have a sump pump on hand. So I just want to make sure I don't burn up the pump motor my husband just had rebuilt. I have cartridge filters so there is a drain on the bottom of the egg or there is a three way handle /valve. I have read about putting the vacuum in and letting the head sit at the deep end. What's the best way to do this? I will need to drain below the skimmer basket.
Any suggestions appreciated,
