Roca Dual Flush Toilet Cistern Flush Valve Base Sealing Washer AH0007100R
If your Roca dual flush valve won't seal properly and is constantly passing water into the toilet pan but there is no sign of an inlet valve failure, it could very well be that the base sealing washer needs to be changed.
Over time as the flush valve is opened and closed, small imperfections tend to occur in the surface of the rubber washer causing the washer to be warped and not providing an adequate seal.
Many make the mistake of purchasing a full replacement flush valve at the first sign of any issue, replacing just this washer may save you a lot time and money in the long-term.
We advise purchasing a couple of these washers at a time so you've got one readily available in the event that the washer fails again in future.
Suitability: Suitable only for Roca D1D and D2D dual flush valves.
Internal Diameter: 16mm
External Diameter: 68mm
