Can you see your drain yet? I've put in 32 gal. of chlorine since fri. This morning I can finally see my drain and the CL is holding at 20 ppm. Finally! On the down side my new pump sprang a leak at the housing gasket. So I'm off to throw some money at my pool store this morning. I would think hayward would replace it for free, but I can't have my pump down at this stage. Good luck
