Won't vacuum loses prime

[Stellabell]

My filter seems to be working fine until I start to vacuum. It will work for. Few minutes then loses suction and prime. I went and bought a new hose today thinking it was getting air in the line. Any suggestions would be appreciated because my husband is wanting to order a load if dirt to fill it in

Hi Stella,

Do you have a valve that controls suction between the main drain and the skimmer? If you are completely closing off the drain, sometimes too much suction can collapse the hose and cause restriction in the suction line. Open that valve up a bit and see if that helps.

I had the same problem

All I had to do was lubricate the pump basket lid "O" ring with silicone grease or Vaseline
