Where should a pool check valve be installed?
Where should a pool check valve be installed?
As such, a common location for a check valve is on the incoming suction pipe, in front of the filter pump. For best results with pump priming, especially for pumps lifting more than 24” from the water surface, the check valve should not be installed directly against the pump intake, but 12”-18” in front of the pump.

Does a check valve go before or after a pump?
On booster pump applications, a check valve can be placed on the suction or discharge of a centrifugal pump. If an additional check valve is required, it should be placed after the pressure tank to allow the pump and discharge pipe to remain pressurized.
How long do pool check valves last?
between 5-7 years
Pool valves tend to last between 5-7 years before the exterior plastic parts need to be replaced. As long as the internal parts are working handles can be replaced. If the valves are older than 10 years you may want to replace the whole thing versus replacing just handles.
Does my pool need a backflow preventer?
Backflow preventers are an important component to your backyard sprinkling system. Without these, municipality drinking water would become contaminated.
Do you need a backflow preventer for a pool?
Underground swimming pools also require a testable backflow preventer (PVB). To ensure water quality and for the protection of our customers, the BRWCD reserves the right to inspect all connections to our system for possible cross connections.
How far should a check valve be from a pump?
In submersible pump applications, the first check valve should be installed directly on the discharge head of the pump or maximum one pipe length (20 feet) above pump. Water pumped and flowing through a piping system has a certain amount of energy (weight x velocity).
How much does a check valve reduce flow?
Two, they are prone to jamming in the closed position, preventing water flow in any direction. And three, they can restrict water flow. In experiments I’ve conducted I’ve measured as much as a 50% reduction of water flow when a check valve is installed and working properly, i.e., it’s fully open.
Will a check valve increase water pressure?
Check valves do not reduce pressure, they actually help maintain it. In the setup you describe, it might work. However you will DEFINITELY need another check valve on the outlet of the tank to prevent the high pressure flow from backwashing in through the bottom, since there is no shuttoff/float valve there.
