We have a 17000 gal pool . What size pump should we have
 Reply

A  Answered on 7/23/2016 by InyoPools Product Specialist Scott W.

It's going to depend on the feet of head, or the distance between your pump and the main drain and the size of your filter. You don't want a pump that has too high of flow rate that your filter can't handle.

I re-installed the cover with the bump handle on my EC40 after it was cleaned and stored from last season, tightening the bolts by alternating opposite sides of the cover, and applying even torque to all bolts. Turn on the filter, and surprise, the whole cover is leaking like Niagara Falls. Water coming out evenly from all around the cover. What happened?
 Reply

A  Answered on 6/21/2018 by InyoPools Product Specialist Lennox H.

Hi, Lou, I would recommend that you check the installation of the Diaphragm Gasket. That is the only reason you filter will leak as described.

Is there a sealant/ lubricant recommend for installing this part?
 Reply

A  Answered on 6/12/2018 by InyoPools Product Specialist Hector F.

You do not need to use lubricant or sealant on this gasket but you can use a small amount of magic lube in order to help keep the gasket from dry rotting.
