What is a Tap Washer?
That constant drip from your tap isn't just a bit of a pain — it wastes water and could potentially be costing you money. If you’ve tried turning the tap harder or wiggling the handle but the drip keeps coming back, you most likely could have a bad washer. The good news is that tap washers are pretty easy to service. This article explains what they do, how to spot problems and how to replace tap washers.
What is a tap washer?
A tap washer is a small disc inside your tap. It creates a watertight seal against the tap seat (a small opening) when you turn the tap off. This seal stops water from flowing through.
You'll find tap washers in most standard taps. In mixer taps, washers help control your water's flow and temperature.
Types of tap washers
Your tap may have any of these types of washers:
- Standard rubber washers: These traditional washers are shaped like a ring with cornered edges. They're common and easy to replace.
- Jumper valve washers: These washers have a flat side and a curved side. They come built into the jumper valve for specific tap styles.
- O-ring washers: These washers are similar to rubber washers but with round edges.
- Ceramic washers: These washers are usually part of modern tap systems. The discs are more durable and long-wearing.
How to spot problems with your washer
When tap washers work properly, you get a clean shutoff every time you close your tap. As they wear down, you get drips because the washer can't press firmly enough against the seat to stop the water.
You can spot a bad tap washer from more than just drops — your taps might squeak, bang or whistle when you turn them. The handles can get stiff and hard to turn. You might notice uneven water pressure or spurting.
How to change a tap washer step-by-step
Before you start, check if you have ceramic disc taps. These look different inside and usually need a plumber to replace them. For standard taps, here's how to change a washer:
- Turn off your water at the isolation valve under your basin or at the mains.
- Plug your drain to catch any small parts.
- Remove the tap button (the hot/cold indicator) with a flat screwdriver.
- Unscrew and remove the handle.
- Take off the tap skirt with pliers.
- Remove the tap bonnet with a spanner.
- Find the washer at the base of the jumper valve.
- Replace the old washer and check it matches the original size.
- Clean any limescale while you have the tap open.
- Put everything back together in reverse order.
- Turn your water back on and test for leaks.
A few extra tips for success:
- Take photos of each step so you remember how it goes back together.
- Clean all parts before reassembly.
- Don't over-tighten when putting it back together.
- If you have two taps, replace the washers on both at the same time.
Troubleshooting
If your tap is still dripping after changing the washer, here’s what to check for:
- The washer size might be wrong.
- The tap seat could be damaged and need grinding.
- Your tap might have other worn parts that need replacing.
