lrodptl Posted June 16, 2017 Report Share Posted June 16, 2017 My neighbor complained to me her pump basket would fill with all air in 15 minutes. She had 2 pool companies pressure test the suction lines and they were good. Is 45 minutes of holding pressure good enough? I went over there and checked the impeller,basket gasket,basket drains and fittings and they are all good. I snaked out the line for an obstruction and it was good. It is a 40 year old gunite pool with original DE filter,that had the elements and Valpak backwash valve changed last year. When I ran the pump,it never got to more than 75% water in the basket. Any ideas? Quote Link to comment Share on other sites More sharing options...
Pool Clown Posted June 19, 2017 Report Share Posted June 19, 2017 Is this a variable speed pump? It is not uncommon for a basket to not completely fill up on a variable speed pump. Quote Link to comment Share on other sites More sharing options...
