Opella / Fluidmaster Toilet Syphon Diaphragm

Approx 148mm x 87mm

Application :

If your toilet won't flush or requires several pressings on the handle to make it flush properly (or at all), then the chances are that the large diaphragm washer (membrane) inside the syphon is damaged. They can crack, disintegrate or fold over and any one of these faults can stop the WC flush mechanism from working properly.
