Replacing a worn washer is a common way to fix a dripping tap. This guide outlines the essential steps based on the typical process for traditional compression taps.
Essential Steps for Replacing Your Tap Washer
Follow these steps carefully to safely and effectively replace the rubber washer in your tap valve:
-
Step 1: Turn Off The Water.
The critical first step to removing your tap washer is turning off the water supply to the tap. Look for a small isolation valve on the pipe leading to the tap, usually located under the sink or basin. Turn this valve fully clockwise to shut off the water. If there's no isolation valve, you'll need to turn off the main water supply to your property. Always turn the tap on briefly after shutting off the water to drain any remaining water and confirm the supply is off. -
Step 2: Block The Plug Hole.
Small screws or tap components can easily fall and get lost down the drain. Block the plug hole before you begin dismantling the tap. A simple plug or even a cloth placed over the drain cover will suffice. -
Step 3: Remove The Tap Head.
You need to access the internal valve mechanism. The tap head or handle typically needs to be removed first. Look for a decorative cap (often a small plastic or metal disc) on top of the handle; this can usually be gently prised off with a thin flathead screwdriver. This will reveal a screw underneath (often a Philips or flathead screw). Unscrew this and lift the tap handle off. You may then see a shroud or gland nut covering the valve spindle; you'll likely need a spanner or adjustable wrench to unscrew and remove this entire internal spindle assembly. -
Step 4: Remove The Tap Washer.
Once the spindle assembly is removed, examine the bottom end. You will see the old rubber washer held in place by a screw. This worn washer is usually the cause of the drip. Use a screwdriver to unscrew the retaining screw and remove the tap washer. It's a good idea to take the old washer to the hardware store to ensure you buy a new one of the correct size and type. -
Step 5: Replace The Tap Washer.
Place the new washer onto the end of the spindle assembly and secure it firmly with the screw you removed in the previous step. Ensure the washer sits flat and correctly in place. Now, you need to reverse the steps you took to dismantle the tap: carefully re-insert the spindle assembly into the tap body, tighten the shroud or gland nut with your spanner or wrench (don't overtighten), refit the tap handle or head, screw it back on, and replace the decorative cap.
