How to Fix a Leaking Tap at Home (Step-by-Step Guide for Beginners)?

If your tap is leaking, the most common cause is a worn-out washer, O-ring, or cartridge. Simply turn off the water supply, open the tap, replace the damaged part, and reassemble it. This fix usually costs between ₹20–₹200 and takes 20–40 minutes.

🧰 Understanding the Problem

A leaking tap is one of the most common household issues in Indian homes. While it may seem minor, a dripping tap can waste 15–20 liters of water daily, increasing your water bill and causing long-term damage like stains, rust, or even seepage.

🔍 Common Reasons for Tap Leakage:

1. Worn-out washer – Most common issue in older taps
2. Damaged O-ring – Causes leakage near the handle
3. Faulty cartridge – Common in modern mixer taps
4. Corroded valve seat – Due to hard water deposits
5. Loose parts – Due to regular wear and tear

Understanding the cause helps you fix the issue quickly and correctly.

You don’t need expensive tools. Most items are easily available in local hardware shops.

Basic Tools:

• Adjustable spanner (₹150–₹300)
• Screwdriver (flat-head & Phillips) (₹100–₹200)

⚠️ Safety Precautions

Before starting, keep these safety tips in mind:

🔧 Step-by-Step Guide to Fix a Leaking Tap

Step 1: Turn Off the Water Supply

Locate your home’s water valve (usually near the meter or under the sink) and turn it off.
👉 This prevents water from flowing while you repair the tap.

Step 2: Plug the Drain

Use a cloth or stopper to block the drain.
👉 This prevents small screws or parts from falling inside.

Step 3: Remove the Tap Handle

• Use a screwdriver to remove the screw (usually hidden under a cap)
• Gently pull off the handle

👉 In older taps, the screw may be visible. In modern taps, look for a decorative cap.

Step 4: Unscrew the Valve or Cartridge

• Use an adjustable spanner to loosen the valve
• Turn it anti-clockwise to remove

👉 Be gentle to avoid damaging threads.

Step 5: Inspect the Internal Parts

Now check for damage:

• Washer → If worn or cracked, replace it
• O-ring → If loose or broken, replace it
• Cartridge → If damaged, replace completely

👉 Carry the old part to the shop to get the exact match.

Step 6: Replace the Faulty Part

• Insert the new washer or O-ring properly
• If replacing cartridge, align it correctly

👉 Apply plumber’s tape on threads to prevent future leaks.

Step 7: Reassemble the Tap

• Screw the valve back tightly
• Attach the handle
• Fix the screw and cap

👉 Ensure everything is snug but not over-tightened.

Step 8: Turn On Water Supply & Test

• Slowly turn on the water supply
• Check for any leakage

👉 If no dripping occurs, your repair is successful!
