I was told I need a Pentair 2" check valve 263042. is this it? Also need Hayward tank adapter de2400pac2cs. Do you have one?

A  Answered on 5/7/2015 by InyoPools Product Specialist Patrick P.

Hi Gretchen, this particular valve is not the Pentair 263042 Check Valve however we do carry the Pentair 263042 Check Valve. We also carry a Generic Version of the Pentair 263042 which will save you some money. For the Hayward tank adapter part # of de2400pac2cs can you double check this number as this is not showing as a good prat # with Hayward, please email us back with what you come up with.

Can this be installed vertically or only horizontally?

A  Answered on 8/5/2017 by InyoPools Product Specialist Alex V.

Rich, Yes, the valve can be mounted vertically. The flow of the water must be moving up. The flow of the water cannot be moving down.

I have a variable speed pump that runs at low RPM most of the time. This reduces check valve flow and causes spa waterfall to run at a trickle. Would the 2 lb spring pressure be too much to overcome at low pump speeds? Is a 0.5 lb spring available in this model?

A  Answered on 12/12/2017 by InyoPools Product Specialist Lennox H.

Hi, Tim.  A 2Lb check valve can be too strong for a variable speed pump running at low rpm's to engage completely. A 1/2 lb spring check valve will require less water flow than the 2lb.

Is this good for 1.5" pipe on both the inlet and outlet side. Thanks!

A  Answered on 5/8/2019 by InyoPools Product Specialist Joe S.

Yes, this would be perfect for 1.5" pipe.
