Spring Loaded Check Valve (Female Bonded x Female Bonded) - White Schedule 40 PVC

The Schedule 40 PVC spring-loaded check valve is designed to prevent water flow from reversing in your hydraulic systems. With its female glued x female glued connections, it is easy to install and guarantees a reliable seal.

It is particularly useful when the filtration system is located below the water line , as it prevents water from flowing back when pumps or equipment are opened for maintenance. It is also found in pools with overflowing spas or coping stones , where it blocks the flow of water from the high point to the low point when the pump stops.

Made of white and transparent PVC , it allows a quick visual inspection of the internal mechanism and ensures excellent resistance to chemicals and pressure.
