A dripping tap might seem minor, but it’s one of those problems that quietly wastes water, increases bills, and signals wear in your plumbing system. If you’re ignoring it, you’re effectively paying for water you’re not using. Understanding how to stop dripping taps properly is the difference between a quick fix and a recurring plumbing issue.

At Mr24HourPlumber, we regularly attend emergency callouts across the Cotswolds where small leaks were left too long and escalated into avoidable repairs.

Why Your Tap Is Dripping in the First Place

Before you try to fix anything, you need to understand what’s actually failing. A dripping tap is usually caused by worn internal components rather than a complex plumbing fault.

Common causes include:

  • Worn washers
  • Damaged O-rings
  • Faulty ceramic cartridges
  • Loose or corroded valve seats

Each of these components controls water flow. When they degrade, water continues to escape even when the tap is “off”.

If you don’t identify the cause, you’ll end up guessing, and guessing leads to repeat problems.

Turn Off the Water Supply First

This should be obvious, but it’s often rushed or ignored.

Before doing anything:

  • Shut off the water supply under the sink or at the main stopcock
  • Open the tap to release remaining pressure

Skipping this step can turn a simple repair into a messy, avoidable situation.

Identify Your Tap Type

Not all taps are built the same, and using the wrong fix is a common mistake.

You’ll typically have:

  • Traditional compression taps (washer-based)
  • Modern mixer taps
  • Ceramic disc taps

Each requires a different repair approach. If you don’t know what you’re dealing with, you’re already at risk of doing it wrong.

Replacing Washers (Most Common Fix)

In older compression taps, a worn washer is usually the culprit.

To fix it:

  • Remove the tap handle
  • Unscrew the valve
  • Replace the worn washer at the base

It’s a simple repair, but only if the washer is the actual issue. If not, the drip will return quickly.

Check and Replace O-Rings

O-rings create a watertight seal within the tap mechanism.

If they’re damaged:

  • Water leaks around the handle
  • Dripping continues even after tightening

Replacing them is inexpensive, but requires correct sizing and proper installation. A poorly fitted O-ring is just a temporary fix.

Ceramic Cartridge Issues

Modern taps often use ceramic cartridges instead of washers.

When they fail:

  • The tap drips continuously
  • Turning the handle doesn’t fully stop water flow

Cartridges are not usually repairable, they need replacing. Getting the correct model is essential, or the issue won’t be resolved.

Don’t Ignore the Valve Seat

The valve seat is where the internal washer or cartridge seals against the tap body.

If it’s corroded or uneven:

  • Even a new washer won’t stop the drip
  • Water will continue to escape

This is often overlooked, and it’s where DIY repairs fail.

When a Dripping Tap Isn’t a Simple Fix

Here’s the reality: not every dripping tap should be treated as a quick DIY job.

You should stop and call a professional if:

  • The drip returns after replacing parts
  • You can’t identify the tap type
  • Fittings are corroded or seized
  • Multiple taps are leaking in the property

At that point, the issue may be systemic rather than isolated.

The Cost of Ignoring a Dripping Tap

A single dripping tap can waste thousands of litres of water per year. That’s not just environmental waste, it’s unnecessary cost.

If left unresolved, it can also:

  • Damage fittings over time
  • Increase pressure on other plumbing components
  • Signal wider system wear

Small leaks don’t stay small forever.
