Protect your home from backflow with our PVC drainage check valves!
The check valve is the essential safety component of your drainage system. Its role is crucial: letting wastewater flow to the sewer or septic tank while preventing any accidental return of liquid or bad odours into the house. At Jardiboutique, we have selected high-performance grey PVC drainage check valves, designed to instantly block backflow caused by public sewer overload or heavy storms. It's the ultimate protection for your basement installations, garages or low-point sanitary fittings.
Available in standard diameters (from 32 mm for a washbasin to 100 mm for a main drain), our check valves are fitted with a movable flap providing a perfect seal. Made of high-strength PVC, they withstand domestic wastewater and repeated use without loss of efficiency. With Jardiboutique, secure your plumbing for the long term and avoid damage from network flooding.
Jardiboutique's technical tip: A check valve must remain accessible to ensure it works properly. Installation tip: Always install your check valve perfectly horizontal so the flap can close properly by gravity. Strictly follow the direction of flow indicated by the arrow on the fitting body. Maintenance: We recommend checking the valve once a year. Residue (grease, hair) can sometimes build up on the flap seat; a simple rinse with clean water is enough to restore a perfect seal. Did you know? Some of our models feature a manual locking lever to shut off the drain during an extended absence for total security.
