Lisalou Posted July 19, 2018 Report Share Posted July 19, 2018 Looking for information. I haven't used the recirculation option on my sand filter, but recently when shocking the direction was to run on recirculate. When I do that, the pool is draining???? any suggestions? as I don't think this is supposed to happen..... Quote Link to comment Share on other sites More sharing options...
Pool Clown Posted July 27, 2018 Report Share Posted July 27, 2018 Correct, the pool should only "drain" when the valve is in backwash. Recirculate should merely just by-pass the filter and return to the pool. Do you get some water back through the returns in recirculate? If so, you may have a ripped or damaged spider gasket in the valve body causing water to leak into the backwash port and drain out. I'm also assuming that when you say the pool is draining that you are getting water out of the backwash line, yes? Quote Link to comment Share on other sites More sharing options...
