Most standard domestic pillar taps in the UK and many other regions use 1/2 inch washers, but it is best to measure the diameter of the old washer or the valve seat before purchase.
Generally, no, but a small amount of plumbers' grease can help the washer seat correctly if the tap is particularly difficult to turn.
Yes, this washer is designed to withstand standard domestic hot and cold water temperatures.
The lifespan depends on water quality and how often the tap is used, but typically they last several years before hardening and requiring replacement.
Yes, it is essential to shut off the water supply to the specific tap you are working on to prevent flooding during the repair.
The valve seat may be pitted or damaged. You may need to use a tap reseating tool to smooth the surface before installing a new washer.
Verify that your tap size is exactly 1/2 inch, as some older or specialty taps may require metric or non-standard sizes.
To install, first isolate the water supply by turning off the local or mains stopcock. Unscrew the tap headgear using an adjustable wrench, remove the old washer, and clean the valve seat of any lime scale or mineral deposits. Insert the new 1/2" dome washer into the jumper, and reassemble the tap carefully. Always ensure the tap is fully closed while tightening to prevent over-compression. Store unused washers in a dry, cool place away from direct sunlight to maintain the integrity of the rubber.
