Restore optimal performance to your Wirquin Jollyfill or Topy inlet valve with this genuine Wirquin Pro Diaphragm Washer Seal (Part No. 10717797). If your cistern is continuously filling or won’t shut off correctly, a worn diaphragm washer is often the culprit.
Over time, repeated opening and closing of the valve can cause the diaphragm washer to develop small tears or lose flexibility, compromising its ability to create a watertight seal. Additionally, debris in the water supply—especially following plumbing works in the area—can accelerate wear and tear on the washer.
Rather than replacing the entire inlet valve, swapping out this small but vital part can be a quick, cost-effective fix. It's an easy solution that can save both time and money while extending the life of your valve.
