Built for performance and durability, these check valves are an essential component in any system where preventing reverse flow is critical—whether it’s irrigation, aquaponics, hydroponics, pools, or general plumbing. Each valve features a corrosion-resistant stainless-steel spring mechanism inside a heavy-duty Schedule 40 PVC body. The spring allows water to flow freely in one direction, and automatically closes when flow stops, effectively preventing backflow and helping to protect sensitive equipment such as pumps, filters, and pressure tanks.
How to Use a Spring Check Valve: A spring check valve should be installed in-line on a pressurized water line where you want to ensure one-way flow. These valves work automatically—no manual operation is needed. Simply: Identify the flow direction (marked with an arrow on the valve body).
Cut your PVC pipe and dry-fit the valve in place, making sure the flow arrow points in the direction you want water to move. Use PVC primer and solvent cement to glue the slip/socket ends of the valve to your 1-inch Schedule 40 PVC pipe. Allow curing time as recommended by the cement manufacturer before pressurizing the system.
These valves can be installed in either horizontal or vertical positions, but for vertical applications, make sure the flow is upward to ensure proper function of the spring mechanism.,Built for performance and durability, these check valves are an essential component in any system
