Why is my tap leaking? Common causes of leaky taps

One of the first questions to ask when you discover a leaky tap is, “Why is my tap leaking?” There are a few common reasons for this issue:

Worn-out washer: The most frequent cause of a leaking tap is a worn-out washer that needs replacing.
Damaged valve: If the valve in the tap’s seating is damaged, it can also lead to persistent dripping.

In both cases, you’ll need to turn off your water supply before making repairs. If you’re unsure where the water shut-off valve is, ask someone familiar with plumbing or call a professional plumber.

Tools you’ll need to fix a dripping tap

Before you start fixing a dripping tap, gather all the necessary tools to avoid any interruptions during the process. Here’s a checklist:

Washers (Ensure you have the correct size or a variety)
Tap/jumper valve
O-ring
Wrench
Spanner
Multi-grips
Lubricant (such as WD-40)
Paper towel or rag

Step-by-Step Guide: How to fix a leaking tap

Step 1: Remove the Tap Cover and Handle

Start by removing the tap cover, usually marked with ‘H’ for hot and ‘C’ for cold, using a spanner. Unscrew the tap handle and take off the bonnet and tap head. Be careful as the washer, O-ring, and valve might come loose, so cover the sink drain to prevent any parts from falling in.

Step 2: Replace the Faulty Parts

Next, replace the worn-out washer, O-ring, or valve with the new parts from your local hardware store. You can use a lubricant like WD-40 to make the process smoother.

Step 3: Reassemble the Tap

Follow the reverse steps to reassemble the tap. Tighten the nuts securely to ensure no parts are loose, which could cause further leaks.

Step 4: Turn On the Water and Test the Tap

Once you’ve reassembled the tap, turn the water supply back on and test to ensure there are no more leaks. If you’re still experiencing issues or don’t feel confident, it’s best to call a professional plumber for assistance.

How to fix a single-lever mixer tap leak

If you have a single-lever mixer tap, the process for repairing a dripping tap is slightly different. A leaking spout usually indicates a cartridge replacement, while a leaking handle suggests the O-ring needs replacing.

To fix your leaking mixer tap:

1. Remove the spout: Unscrew any screws securing the spout in place.

2. Replace the seal or washer: Swap out the faulty seal or washer with a matching part.

3. Reassemble the tap: Reverse the steps to put the mixer back together and test for leaks.

Always ensure you get the correct cartridge for your brand, as they can differ significantly.
