A range of rubber washers to service/repair a variety of toilet cistern inlet valves.
In the majority of cases, when a toilet cistern is either not filling or continually filling, the inlet valve requires either replacing or servicing.
In most cases the structure of the valve is fine, it's the perishable washer that has failed and replacing a cistern inlet valve washer is generally a simple job and well within the realms of the average householder.
Please visit our 'how to' section on the home page for a link to video describing the sequence.
Instead of incurring the unnecessary expense of replacing a cistern inlet valve, just replace the washer, after all you wouldn't replace your car if it run out of petrol!
