I just bought this house which is a fixer upper. After draining the pool, acid washing it. I now see that I have a crack near the deep in. I have read other threads indicating to use Hydraulic cement to fix this. I used my angle grinder to open up the crack, and used the hydraulic cement to fill the crack. some parts of the crack have stopped leaking. However I still have two parts where I still have a leak. I can not move on to replastering the pool until this is fixed.
Any ideas on what I can try next to stop this leak? Any help is greatly appreciated.
