PVC check valve

PVC check valves: the backflow stop built into your glued network

The PVC check valve is a non-return valve designed for PVC pressure pipe: it glues straight into the line like a standard fitting, with no thread involved. Its PVC body blends with your elbows and couplers for a perfectly continuous network. It is the cleanest solution when the whole circuit is already solvent-weld PVC. Our Piscine-SAV experts prefer it for discreet, durable inline assemblies.

Our range of PVC check valves

• Female-female glue valve: it fits between two PVC pipes by simple solvent welding.
• PVC spring valve: its stainless spring shuts the passage as soon as flow stops.
• PVC ball valve: an internal ball blocks backflow, ideal in the vertical position.
• Clear-body valve: its translucent body lets you check the flap works.

Choosing the right PVC check valve

• Confirm your network is solvent-weld PVC pressure, not threaded.
• Respect the flow-direction arrow before gluing permanently.
• Check the diameter for a perfectly tight socket and bond.

The Piscine-SAV technical tip: unlike a threaded valve, the PVC valve is glued and cannot be removed, so aim the arrow correctly first. Check the diameter; if in doubt, send us the reference and we will confirm the right PVC valve for you.
