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. Dead easy to replace, instantly stopped toilet constantly self flushing slightly, didnt even need any tools that's how easy it was to replace, saved me a small sum of money ( plumbers labour) watched you tube for self tutorial, job done in 2 minutes. This replacement seal is built to suit the SV range of valves fitted to many Armitage Shanks and Ideal Standard WC Toilet cisterns.

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. NOTE: Replacing the diaphragm may not always resolve your problem as the fault could be with the valve itself but it is a cheap way to try and resolve and is usually successful. Ideal Standard have only ever manufactured one type of seal and clip, so if you have a seal and clip like this, then this listing will be the replacement you require. The Ideal Standard dual flush valve seal and clip (SV01967) is a genuine, brand new Ideal Standard product, covered by a minimum 1 year Ideal Standard manufacturer's guarantee. New part fitted in less than 5 minutes, and all i needed was a flat head screwdriver to pop the old on out.TEST: If you turn the water off (from the stop cock bringing water into the house OR an isolating valve on the cistern), leave it for up to an hour, does the cistern empty? If you have water running into the toilet pan continuously and are not sure if you need to purchase a spare part / replace the flush valve or inlet/fill valve you can try this simple test to determine.

I cut off the old ring using a fine junior hacksaw because I couldn't easily prise out the clip tangs with a screwdriver. The Ideal Standard SV01967 Dual Flush Valve Seal is a genuine Ideal Standard product, covered by a manufacturer's guarantee.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.
