How to Fix a Dripping Tap: A Step-by-Step Guide for DIY Homeowners

Is the constant plink...plink...plink of a dripping tap driving you mad? Picture your quiet kitchen or bathroom, the silence broken only by that irritating drip echoing in the background. Sound familiar? You’re not alone. A leaking tap is one of the most common household plumbing annoyances.

But here’s the good news: in many cases, it’s something you can tackle yourself. In this guide, we’ll walk you through how to fix a dripping tap safely and effectively. If things don’t go to plan, we at DMA Property Solutions are here with trusted plumbing services to step in and take the stress away with an expert dripping tap fix.

Why You Shouldn't Ignore a Dripping Tap

Here we are going to be completely honest: leaving a dripping tap unrepaired isn’t just annoying, it’s costly. Over time, even the smallest leak can waste hundreds of litres of water, pushing up your bills without you even realising.

The environmental impact alone is reason enough to act quickly. Beyond that, water can trickle down into cabinets, corrode fixtures, and lead to hidden damage you won’t spot until it’s too late.

You may ask, “How do I fix a dripping tap before it causes bigger problems?” This blog offers clear steps for dripping tap repair so you can handle the issue head-on and protect your home. So, with all that said, let’s explain how to fix a dripping tap.

Tools You’ll Need for the Job

First things first, before you roll up your sleeves, make sure you’ve got everything you need for a safe and smooth leaking tap repair.

Here’s a list of essential tools:

  • Adjustable Spanner: To loosen and tighten parts
  • Screwdrivers (Flathead and Phillips): For removing handles and taps
  • Replacement Washer or Cartridge: Depends on your tap type
  • Cloth or Rag: To protect chrome and catch drips
  • Allen Key: Often needed for monobloc lever tap repair
  • Plumber’s Grease: For reassembly and smooth operation

Remember, before you begin, always TURN OFF the water supply before you start, and keep a towel nearby in case of unexpected spills.

Step-by-Step: Fixing a Traditional (Compression) Tap

If your tap needs more than a quarter turn to release water, you’re dealing with a compression (traditional) tap. Here’s how to fix a dripping tap properly and avoid wasting water.

1. Turn Off the Water Supply

Locate the isolation valve under the sink and turn it off with a screwdriver. If there’s no valve, use the stopcock, usually found under the kitchen sink, to shut off the main supply.

2. Drain the Taps and Remove Covers

Turn on the taps to release any remaining water. Use a flathead screwdriver or Allen key to remove the handle covers and reveal the screws beneath.

3. Remove Handle and Valve

Undo the screw at the top of the tap head. Using an adjustable spanner, loosen the valve and carefully remove it. Lay out the parts for easy reassembly.

4. Inspect the Tap Seating

Feel inside the tap body. If the seat is rough or pitted, use a seat grinder to smooth it out. Alternatively, a seat insert kit can help form a new, watertight seal.

5. Replace Tap Washer

This is a common cause of leaks. Check the washer for wear, and if it’s cracked, hard, or misshapen, replace the tap washer with a new one of the same size.

6. Reassemble and Test

Grease moving parts lightly, reassemble the tap in reverse order, then turn the water back on. Check for leaks. If done correctly, your dripping tap repair should now be complete.

Learning how to fix a dripping tap can save money and prevent water damage. If it doesn’t go to plan, our expert plumbers are just a call away.

Step-by-Step: Fixing a Ceramic Disc Tap

If your tap turns only a quarter of the way, there’s a good chance you have a ceramic disc tap. These modern fixtures are known for their durability, but when they start to drip, the fix usually involves replacing the tap cartridge.

Follow these steps to complete the task safely and effectively.

1. Isolate the Water Supply

First, locate the isolation valve under or near your sink. Turn it off using a flathead screwdriver, and if you can’t find it, turn off the main stopcock, typically found under your kitchen sink. This is essential before attempting to repair ceramic disc taps.

2. Drain the Taps

Run the affected tap until water stops flowing. This ensures the system is fully drained. Plug the sink to avoid losing any small parts during disassembly.

3. Remove the Tap Head

Look for a small screw securing the headgear; this may be accessed with a crosshead screwdriver or an Allen key. Once removed, lift off the headgear or unscrew the valve cover. If it’s stiff, use an adjustable spanner with care.

4. Remove and Replace the Cartridge

Loosen the hexagonal nut at the valve neck and hold the tap body steady to avoid damaging the pipework. Once free, remove the cartridge. For an exact tap cartridge replacement, take the old unit to a DIY store. Note whether it's left or right-handed.

5. Reassemble the Tap

Install the new cartridge and reassemble all parts in reverse order. Turn the water back on and test. If you're unsure about whether to replace tap washer components or the cartridge itself, it’s best to consult a plumber.

Fixing a Leaking Mixer Tap Spout (O-Ring Replacement)

A mixer tap that drips from the base often has a worn-out O-ring. Fortunately, replacing the O-ring on a tap valve is a relatively straightforward job. Let’s walk you through it.

Spotting the Issue

If you notice a leak at the base of the spout, chances are that the O-ring has failed.

6 Steps to Replace Spout O-Rings

  1. Turn off water supply
  2. Remove the retaining nut or collar at the spout base
  3. Lift off the spout carefully
  4. Remove the old O-rings with a screwdriver or scissors
  5. Grease and replace spout O-rings
  6. Reassemble, ensuring everything is aligned

This type of O-ring replacement for the tap valve should stop the leak without requiring the replacement of the entire tap.
