The PEPTE Dome Tap Washers are essential maintenance components for homeowners and plumbers looking to repair leaking 3/4-inch tap cartridges. These durable washers provide a reliable seal to stop drips and extend the life of your plumbing fixtures, though it is important to note that the 3/4-inch designation refers specifically to cartridge compatibility rather than the washer's physical dimensions.

No, the 3/4-inch designation refers to the compatible tap cartridge size. The physical outer diameter of the washer is 23mm.
Check your existing cartridge label or measure your old washer. It should match the 23mm outer diameter and 4.8mm internal hole diameter provided.
You typically need an adjustable wrench, a screwdriver for the handle screw, and a cloth to protect chrome finishes.
While not strictly necessary, a small amount of heat-proof, food-safe silicone grease can help the washer seat correctly and prevent future wear.
Replacement frequency depends on usage and water hardness. Replace whenever a drip appears or if you notice reduced water flow due to washer deformation.
Ensure the washer is seated properly and check the tap seat for pits or scratches that may prevent a tight seal.
Verify the cartridge size matches the 3/4" specification and ensure no old rubber fragments remain in the housing.
Before starting, you must shut off the water supply at the local isolation valve or the main stopcock to prevent flooding. Carefully dismantle the tap handle and cartridge housing using an adjustable wrench. Remove the old washer, clean any debris or limescale from the seating area, and seat the new 23mm dome washer firmly. Ensure the cartridge is tightened correctly during reassembly, but avoid overtightening, as this can compress the washer prematurely. Regularly check your taps for debris buildup to ensure the washers remain in good condition.
