I'm trying to drain my IG to drop the CYA level...does every IG pool have a drain at the bottom of the deepest part? And should it be draining water if the pump is on waste? FYI, there is only 1 valve on the inflow side of the pump.
I'm currently vacuuming through the skimmer on waste trying to drop the level. When the water dropped below the other skimmer the output dropped drastically too.
Thank you in advance
