Feb 27, 2024

Struggling with a Dripping Tap?

A dripping tap is often caused by a worn-out washer. Replacing a tap washer is a simple DIY fix that can stop leaks and save water. This guide walks you through identifying a faulty tap washer and provides a step-by-step guide on how to replace it, complete with essential tools and handy tips.

Key Takeaways

Rubber washers in taps prevent water leaks, but when they wear out, replacing them can save water and reduce bills.
To change a tap washer, gather essentials like screwdrivers, wrenches, and pliers, shut off the water supply, and replace the washer following specific steps.
If tap washer replacement doesn’t fix the leak, or for complex issues, call a professional plumber; consider upgrading to ceramic disc taps for longer-term ease and savings.

Understanding Tap Washers and Their Role in Your Plumbing

Tap washers form a watertight seal in your taps, preventing leaks and ensuring smooth operation. Every time you turn off your tap, the washer stops water from flowing through. Over time, washers can wear out, leading to a dripping tap that wastes water and increases your bills.

Maintaining these tiny components is crucial for your home’s plumbing health. Replacing a faulty washer promptly helps prevent further damage and unnecessary water waste.

What is a Tap Washer?

A tap washer is a small but essential component that creates a watertight seal when your tap is turned off. Located under the valve inside the tap, washers are traditionally made of rubber, while modern tapware may feature ceramic disc cartridges that provide longer-lasting performance.
