My pool has 5 returns tied to a loop. The 2 returns closest to the pump have much stronger flow, as expected. In order to balance all 5 returns with similar flow, do I need to decrease the eye ball size of those 2 fittings from 1" to 3/4"?
I notice there is a vertical crack line in the grout between two waterline tiles at a corner of the pool. Water seems to sip up to the coping stone. What is the best way to stop that leak?
