I am new to this website and to owning a pool. I couldn't find anything on here that definitively answers my question nor do I know how to make a signature with my info so here it is. I have a 14000 gallon inground fiberglass bromine pool with a 1 hp pentair superflow pump I believe and a Cristal flow 2 sand filter. I live in a place with a very high water table in fact the previous owner must've drained to much water because one side of my pool is bowing in. I have 2 questions really I guess. The first is how can I convert from bromine to saltwater without draining the pool? the bromine is just to hard to deal with. I can never keep the level up and the water must be shocked all the time. Secondly my pool goes from 3ft to 8ft and has 2 jets on the shallow side with 1 skimmer on the deep end. It has a dedicated suction port on the side. I do we a drain near the bottom of the deep end but apparently it does not work because the other hole in the skimmer has been plugged which a pool company told me there must've been a leak or something. I think this is why my deep end turns bad so quickly because there just isn't enough circulation to turn the water over without that drain. Can this drain be fixed without tearing up all the concrete?
