Last year I bought a house with an old inground pool that uses a Hayward Super Pump and a Hayward 270T sand filter.
This year, after changing the sand (350 lbs.), I've encountered a problem. When I go to suction the bottom of the pool, the suction on the pump decreases significantly, until there is no water flow whatsoever--there is water in the pump system (because the basket section is full to the lid with water), it's just not moving. After that, I have to switch the pump off and on a couple of times, which starts the water moving again.
It appears to me that the problem is with the pump not having enough strength, so that when it's tasked with suction duties, it slows down to a halt. (Note that the motor is still running). Do I need to replace the impeller? Seals? Can anyone make a recommendation?
Thanks.
