I am installing a Hayward Heat Pro, calls for a 1/3 lb checkvalve, will this one work?
Yes, this check valve should be sufficient.
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.
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?
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?

Great check valve...no chlorine can backflow to your multiport or filter when the pump shuts off. Being clear is also a huge advantage so you can see if anything gets into the check valve on the inflow side. The fact that you can then remove the valve and eliminate any foreign material because of the unions makes this the best check valve we have ever had. Extremely sturdy and well built. Highest recommendation.

Pros: Cost, Accessable for minor maintenance
My order arrived on time and the product worked as advertised. The union connections have already proved useful to facilitate the removal of a minor blockage to the diaphragm.

Pros: Unions on both end allows for quick replacement if needed
The check valve arrived within 5 days. I had already previously purchased a check valve to put in line, but this one I thought would be better as it had the unions on each end thus allowing me more flexibility on installing it.
