I need a new one of these but mine is vertical and flows down is this correct. It's on the spill over spa line.

A     Answered on 7/4/2017 by InyoPools Product Specialist Alex V.

Bernie, The check valve can be installed vertically or horizontally.

How is the rubber o ring inside the check valve suppose to work; in that should the o ring slide back up into the body of the check valve once the pool pump shuts off?

A     Answered on 4/25/2017 by InyoPools Product Specialist Lennox H.

Hi, Jimmy. The black rubber inside of the valve seals the spring shaft so that water does not seep through that part of the valve.

I'm losing my prime on pump. How far from the suction side inlet should I place a check valve? Most of the line is under concrete, I only have about a foot of line to access. Will that work?

A     Answered on 3/20/2015 by InyoPools Product Specialist Robert M.

Hello Bill - The check valve can be installed within a few inches of the intake of the pump. A foot of pipe will be sufficient for the check valve install.

Is it possible to purchase just the insert part of this as a replacement?

There is no replacement part for that and you would need to replace the whole unit.
