A dripping tap can be more than just an annoyance; it can lead to significant water wastage and increased utility bills. Fortunately, fixing a dripping tap is a relatively simple task that most homeowners can handle themselves. In this guide, we’ll walk you through the steps involved in fixing a dripping tap, from identifying the problem to tightening the faucet.
Understanding the Problem:
Before you start, it’s essential to understand the cause of the drip. Here are the most common reasons:
Loose Faucet Handle: This is the most common cause of a dripping tap. Over time, the handle can become loose, allowing water to seep through.
Worn-Out Washer: The washer is a small rubber or plastic disc that seals the valve when the faucet is turned off. If it’s worn out or damaged, water can leak past it.
Mineral Buildup: Mineral deposits from hard water can clog the faucet’s aerator or cartridge, causing drips.
Damaged O-Ring: The O-ring is a small rubber ring that seals the valve stem. If it’s damaged or cracked, water can leak.
Tools and Materials Needed:
Adjustable wrench
Screwdriver
Pliers
Basin wrench
Replacement washer
Replacement O-ring
Plumber’s tape
Rags or towels
Step-by-Step Guide:
Turn Off the Water Supply:
Locate the shut-off valve under the sink or in the basement.
Turn the valve clockwise to shut off the water supply.
Turn On the Faucet:
Open the faucet to release any remaining water pressure.
Remove the Faucet Handle:
Screw-On Handle: Use a screwdriver to remove the screw holding the handle in place. Then, gently pull the handle off.
Lever Handle: Look for a small set screw under the handle. Use an Allen wrench to loosen the screw. Once loose, lift the handle off.
Remove the Faucet Cap:
The cap is the decorative piece that covers the valve stem.
Use pliers or a wrench to unscrew the cap.
Access the Valve Stem:
Once the cap is removed, you’ll see the valve stem.
Use a basin wrench to unscrew the packing nut, which is located at the base of the stem.
Replace the Washer:
Carefully remove the old washer from the valve stem.
Inspect the valve stem for any damage. If it’s damaged, you’ll need to replace the entire valve stem assembly.
Install a new washer onto the valve stem. Make sure it’s seated correctly.
Reassemble the Faucet:
Tighten the packing nut using a basin wrench.
Replace the faucet cap and tighten it securely.
Reattach the faucet handle and tighten the screw or set screw.
Turn On the Water Supply:
Slowly turn the shut-off valve to open the water supply.
Check for leaks around the faucet handle, cap, and base.
Types of Taps and Their Repair Processes
There are different types of taps, each requiring a slightly different repair process:
Compression taps: These have separate hot and cold handles. Leaks typically result from worn washers.
Cartridge taps: These use cartridges to control water flow and may leak if the cartridge or its seals degrade.
Ball taps: Common in kitchens, these have a ball valve that regulates water flow. Leaks usually occur from worn seals or springs.
Ceramic disk taps: These use a cylinder with ceramic disks; leaks occur when the seals between the disks wear out.

Tools and Materials Needed
Screwdriver (flathead or Phillips)
Adjustable wrench or pliers
Replacement washers, O-rings, or cartridges
Plumber’s grease or putty
Needle-nose pliers
Preparation
Turn off the water supply: Locate the shutoff valves under the sink or turn off the main water valve.
Cover the sink drain: Use a cloth or plug to prevent small parts from falling into the drain.
Lay out your tools and parts: Organize everything to avoid delays during the repair.
Disassemble the Tap
Remove the decorative cap (if present) on the handle.
Use a screwdriver or wrench to loosen and remove the handle.
Access the internal parts (cartridge, washer, or disk) by unscrewing any retaining nuts.
Identify and Replace Faulty Components
Compression Tap: Remove the old washer at the end of the stem and replace it with a new one.
Cartridge Tap: If the cartridge is damaged, pull it out and replace it with an identical one.
Ball Tap: Inspect the seals and springs; replace any worn components.
Ceramic Disk Tap: Clean the disks and replace any damaged seals.
Reassemble the Tap
Apply plumber’s grease to O-rings and washers to ensure a proper seal.
Reassemble the tap in the reverse order of disassembly.
Tighten all nuts and screws carefully to prevent over-tightening.
Test for Leaks
Turn the water supply back on.
Slowly open the tap and check for leaks.
If water still drips, double-check the components or consult a professional plumber.
