Check valve

Check valves: water moves forward, never back

The check valve forces a single direction on the water. Its purpose: to let the flow pass one way and block it the instant it tries to flow back. It is the key protection to stop a pump losing prime, a pool draining or dirty water climbing the network. This general range gathers every type of check valve, threaded, brass or spring. Our Piscine-SAV experts point you to the mechanism suited to your flow.

Our range of check valves

• Spring check valve: its spring shuts the passage instantly when the flow stops.
• Swing check valve: a simple, reliable tilting flap for high flow rates.
• Brass threaded valve: sturdy and compact, it connects to metal or PVC threads.
• Ball check valve: a ball lifts to open and drops to close, with no maintenance.

Choosing the right check valve

• Respect the fitting direction shown by the arrow engraved on the body.
• Check the diameter and connection type, threaded or glued.
• Choose the mechanism (spring, swing, ball) according to flow and position.

The Piscine-SAV technical tip: a valve fitted backwards blocks the whole circuit. Find the flow-direction arrow and check the diameter; if in doubt, send us the reference and we will confirm the right valve for you.
