I have water coming into pool under steps in shallow end. My liner need replaced and thinking of changing this spring. my floor in shallow is concrete and deep end is port-land mix. This leak you notice after a month of using the pool the seam from the middle of the steps in the shallow lifts slightly when vacuuming the pool. Only have this problem in shallow in area about width of step and length of shallow end. I have used die and steps are not leaking including return from water side of return. I have had problems with return into steps and could be source of water. My water level is low after winter. (Still have cover on) will check to see level and maybe additional source of leaks. How do you stop water leaking into pool under steps? Any way to repair return into steps with out removing concrete?
