When my pump is running, air is in the bottom filter. Bleeding it off works for a while but the air returns. Also, when we turn the pump off, water shoots up the pool filter. PSI's are fine. We are novices at this. The troubleshooting guide in your manual does not address this. In fact, I am wondering if the gasket on this filter is allowing air to seep in but I can't find where or how to order it on your website. Basket in filter is clean. Any help is appreciated.

A  Answered on 8/4/2017 by InyoPools Product Specialist Alex V.

Mikki, If you suspect an air leak, it will come from the suction side (pump). I would check the hose in between the pump and skimmer and the pump lid o-ring. You can find replacement parts for your system on this parts page.

I'M looking for a sand filter and pump system for a 600-1200 gallons of salt water more or less to keep lobsters alive. Will this work?

A  Answered on 10/12/2016 by InyoPools Product Specialist Alan M.

This system would be more than enough to circulate and filter 600-1200 gallons of water.

how do you remove the sand drain plug on a Pentair SD-40 sand filter?

A  Answered on 6/25/2016 by InyoPools Product Specialist Lennox H.

Hi Steve, The drain plug assembly simply unscrews from the filter tank.

we have an above ground 28' round pool with a pentair water sand filter system ; when the filter is running a water leak generates from the valve flange/plastic clamp area - is there a specific size O ring that we should replace?

A  Answered on 6/17/2015 by InyoPools Product Specialist Lennox H.

Deb, You will need to replace the TA30D,35D,40D,50D,60D Valve Body O-ring (350) to keep the filter from leaking.
