supermanotorious Posted June 27, 2016 Report Share Posted June 27, 2016 I hate that little mesh basket that sits on snorkel above the grid manifold. It's always getting clogged and tearing, then letting unfiltered water enter the manifold. Why is it there? When the pump is running and the filter is in "filtering" mode, there would be suction on that outlet. So if there was air in the filter, it would be sent back in to the pool via the returns. The only time air could escape from this outlet would be when the pump is not running or the filter is in backwash mode. In either case, I do not see why it is important. Please help me understand so I don't just plug it! Quote Link to comment Share on other sites More sharing options...
