How to Change a 
Tap Washer on a Mixer Tap
10 Simple Steps

Step 1: Gather Essential Tools and Materials

Before commencing any repair work, it's essential to be well-prepared. For this procedure, gather the following tools:

• A flathead screwdriver:

This will be handy for prying off caps and unscrewing parts.

• An adjustable spanner or wrench:

Ideal for tightening and loosening parts of the tap.

• Needle-nose pliers:

Useful for gripping small components.

• A cloth or towel:

Lay this down beneath the tap to catch any drips or small parts you might drop, ensuring a mess-free workspace.

• Replacement tap washer:

Ensure it matches the specifications of the old one for a seamless fit.

Step 6: Unseal & Locate The Washer

Peek inside the tap's neck, where the spout used to be. Here lies the seal or washer, responsible for maintaining a watertight fit at the tap's base. Over time, this component wears out, leading to those pesky drips.

Step 7: Remove The Old Washer

Employing the flat edge of your screwdriver or your needle-nose pliers, gently extract the old washer. Remember, this step requires patience; you wouldn't want to damage any surrounding parts inadvertently.

Step 8: Install The New Washer

With the old washer out, it's time for its replacement. Place the new washer in the same spot, ensuring it's seated correctly. This fresh washer will provide an effective seal, preventing any future leaks from the same area.

Step 9: Reassemble The Tap

Begin the reassembly process by retracing your steps in reverse order. Firstly, secure the headgear back in place, followed by the handle. Once these are firmly in place, snap or screw the decorative cap back onto the handle.

Step 10: Restore Water Flow & Test

Reinstate the water flow by turning the main valve back on. Then, operate the mixer tap, allowing the water to run for a few moments. This action serves two purposes: it ensures no leaks and helps flush out any debris that might have found its way into the tap during the repair process. If you observe a steady flow with no drips, pat yourself on the back for a job expertly executed!

Mixer tap washers form the crucial link in ensuring that water flow remains consistent and leak-free. Though small, the choice of material for these washers plays a massive role in the longevity and performance of a tap. Let's delve into the primary materials used in these washers and their distinct characteristics.

The Reliability of Nylon Washers

One of the most trusted materials in the world of tap washers, nylon offers durability and resilience against wear. These washers stand out for their inherent internal lubrication, reducing friction and enhancing their lifespan. Their non-reactivity ensures they remain unscathed when coming into contact with various substances, and their ability to withstand high temperatures makes them suitable for both cold and hot water taps.

Rubber and Polythene Washers: Pros and Cons

A common sight in showers, baths, and basins, these washers are revered for their adaptability to hard materials, owing to their softer nature when compared to nylon. However, their malleability is a double-edged sword: it ensures a good seal but also means they can deform over time, especially when exposed to frequent compressions. Over time, the natural degradation process might lead them to split or crack, requiring replacements to prevent drips.

The Unique Traits of Fibre Washers

Often known as vulcanised fibre washers, these are treated with sulphur at elevated temperatures, granting them a unique hardness. Their distinguishing feature is the ability to expand when wet, providing an optimal seal. Moreover, they can be compressed more easily than rubber or nylon counterparts, ensuring they stay resilient even if overtightened accidentally.

The Strength of Ceramic Washers

Crafted from fire-hardened ceramics, these are arguably the most robust washers available. With one disc stationary and the other mobile, they offer precise control, are less prone to wear due to their erosion-resistant nature, and ensure smooth tap operations.

Choosing an ideal washer isn't just about identifying the material; it's about understanding its compatibility with your mixer tap. Always ensure the replacement washer mirrors the dimensions of the original: Utilise callipers or a measuring tape for precision. Factors like the washer's longevity, adaptability, and price point should be considered.

Investing in quality guarantees reduced frequent replacements, ultimately leading to cost savings. Lastly, purchase your washers from a trusted plumbing supplier to guarantee that you're fitting your taps with the best available.
