Keep your water systems flowing safely and efficiently with the 247Garden 2-Pack 1-1/2 in. Schedule 40 PVC In-Line Spring Check Valves. These heavy-duty one-way valves are designed to stop backflow and maintain unidirectional water movement—perfect for use in irrigation, hydroponics, aquaponics, pools, water features, and other plumbing applications that demand consistent, controlled flow.

Each check valve features a corrosion-resistant stainless-steel spring housed inside a tough Schedule 40 PVC body. When water flows in the correct direction, the spring opens to allow full flow. When flow stops or reverses, the spring shuts the valve automatically, protecting pumps, filters, and other sensitive equipment from pressure damage and contamination.

How to Use a Spring Check Valve:

Spring check valves are installed in-line with the flow of water in your system:

1. Locate the flow direction arrow printed on the body of each valve.

2. Cut your 1-1/2" PVC pipe to insert the valve where one-way flow is needed.

3. Dry-fit the valve to ensure proper alignment (flow arrow pointing in the correct direction).

4. Use PVC primer and solvent cement to securely connect the slip/socket ends to your Schedule 40 piping.

5. Allow time to cure according to the cement manufacturer's instructions before restoring system pressure.

These valves can be mounted horizontally or vertically, but for vertical installations, water flow must be upward to work correctly with the internal spring.
