Tap washers are intended for use in practically all types of faucets, where their primary function is to aid in the control of water flow. They can also help to prevent leaks and contamination when a faucet is turned off.

They accomplish their goal by constructing an unbreakable physical barrier between the tap seat and the spout.

The material design of most tap washers also allows them to fill and smooth away any irregularly formed areas between different components of a tap fitting, thereby sealing off the tap spout from the valve.

The basic function of a washer, regardless of its type or composition, is to press down on the seat or flow valve on the interior of a tap assembly, establishing a closed-off seal that prevents water from flowing to the spout when the tap head is turned off.

Types of Tap Washers

  • Ceramic Tap Washers: Ceramic tap washers, also known as ceramic disc washers, are commonly seen on contemporary tap assemblies. They are most commonly found on ‘quarter-turn’ taps and monoblocks where the operating mechanism does not need turning the tap head through multiple revolutions to start or stop the water flow.
  • Rubber Tap Washer: Rubber is thought to share many of the features of nylon when it comes to longevity and function in tap washers; however it is a much softer and more pliant material overall. This can imply that it forms a more effective seal against harder materials or where there is more surface irregularity.
  • Nylon Tap Washers: Tap washers made of nylon are a popular choice for closing tap valves. Nylon spacer washers provide a dependable seal on most types of taps due to their characteristics.
  • Fibre Tap Washers: Fibre washers, which are frequently used in many sectors of plumbing, are slightly simpler to compress than rubber or nylon ones. This may mean that they are in less immediate physical danger of harm from over-tightening, which may result in a longer life expectancy depending on the type of tap and how it is used.

How to Change a Washer on a Mixer Tap?

Step 1     

To begin changing the washer on a bathroom mixer tap, cut off the water flow. Depending on your installation, this will have a switch on/off valve. Otherwise, you must switch it off at the boiler.

This will keep your bathroom from flooding. Another piece of advice from our plumbers is to cover the drain with either your drain cover or a kitchen towel. This will keep any screws or smaller items from falling down the drain.

Step 2

Now that your sink is ready to use, remove the reviver from your kitchen faucet by either removing the reviver cover or unscrewing it with an adjustable hold.

The classic reviver will require you to lift the cover-up, possibly with a flat screwdriver with a flat end, and remove the top with a star end screwdriver.

Step 3

We can replace the faulty element, which in this case is the washer after you have access to the inside of the reviver. Take the washer element out as a result.

Plumbers recommend flattening out the metal inside the faucet body with a tap reseating tool now that you can see the space. This tool is generic and will work with any brand.

Step 4

However, when you install the tap reviver, it may be exceedingly tight since some water and sediments may have accumulated within for as long as the leak has been occurring.

Continue to push forcefully with downward and side rotations so that it does not move. Remember that this is only to smooth out the surface, so go slowly.

Step 5

When you have smoothed out the surface and it appears gorgeous, level, shiny, and free of irregularities, you know you have done a good job. To ensure the optimal fit of the washer in the tap, clean out the small filings with lukewarm water.

After you’ve completed filing, screw the washer into the tap body. Screw it in as tight as you can by hand and after that, screw it a little tighter using your adjustable grip to hold it in place.

Step 6

Finally, your tap washer has been successfully replaced. What you want to do now is mount the tap reviver as you did at the beginning of the post.

After that, re-start the water supply and check to see if it works. Allow the water to run for a few seconds to clear the debris from the pipework. Finally, you should be able to use your mixer tap once more.

Safety Tips

  • If you are doing the work yourself, we strongly recommend that you take proper safety precautions to avoid accidents or flooding.
  • When performing any work, read all directions and follow them exactly. When completing any work around the house, you must follow the manufacturer’s recommendations.
  • Before using any tools or equipment, be sure they are suited for the job.
  • If removing the washer does not cure the problem and it is confirmed that the tap seat is the source of the problem, you will most likely need to acquire a tap seat grinder and grind down the seat in the faucet. You could also use the services of a plumber.
