How to Fix a Leaking Pipe

A leaking pipe can appear without warning and cause damage quickly if left untreated. While some leaks need a qualified plumber, there are simple steps you can take to reduce the water flow and protect your home. This guide explains how to fix a leaking pipe temporarily and when to call an expert for a full repair.

Before You Start: Stay Safe

Small drips are usually safe to inspect. However, stop immediately and call a professional if:

Water is leaking near electrical points
The pipe has split or water is flowing rapidly
You smell damp burning or notice heat damage

If you are unsure, turn off your mains water and speak to a plumber. Call us on 01628 533 550 or message us.

Step 1: Turn Off the Mains Water Valve

The first step is to isolate the water supply. Turning off the main stop tap stops fresh water entering the system. You will usually find the valve:

Under the kitchen sink
Near the water meter
In a utility cupboard

Turn the valve clockwise until it stops or just press the switch if you use SureStop.

Step 2: Open Your Taps to Drain the System

Once the mains is off, open the taps around your home. This drains the remaining water from the pipework. The dripping will slow and often stop shortly after the system empties.

Step 3: Use Plumber’s Epoxy Putty for a Temporary Fix

Epoxy putty is a useful emergency product to keep at home. It can seal small leaks for a short period while you wait for a professional repair.

How to prepare the epoxy:

Tear off the required amount
Warm and soften it by kneading
Mix until the colour is even

How to apply it:

Press the epoxy firmly over the leaking area
Extend the patch beyond the hole to create a seal
Smooth and mould it around the pipe

If the leak is at a joint, it may take extra shaping for a secure hold.

Step 4: Allow the Epoxy to Harden

Most plumber’s epoxy hardens within a few minutes. Follow the instructions on the packaging for the exact curing time.

When the putty feels firm, turn the mains water back on slowly. Keep your taps open as the water flows through the pipes. Watch the patched area for any signs of further dripping.

What To Do If The Leak Continues

Sometimes the first patch does not seal completely. If you still see water:

Turn off the mains again
Dry the pipe thoroughly
Apply extra epoxy over the patch
Allow it to harden before testing

If the leak continues after a second attempt, the pipe may be corroded or damaged. A professional plumber will need to replace the section.

Is Epoxy a Permanent Repair For Leaks At Home?

Epoxy is only a short-term solution. It may hold for a few days, but it will not fix a damaged or ageing pipe. A leak can also indicate deeper problems such as corrosion in older pipework or pressure issues within the system.

A qualified plumber should inspect the pipe to prevent future failures.

How Surestop Helps During a Leak

During a major leak, shutting off the mains water quickly can prevent structural damage. Surestop Water Switches make this process easier by allowing you to turn off the water with a simple switch rather than a stiff or awkward stop tap.

Surestop can be helpful for homeowners, landlords and tenants, especially in emergencies. If you would like one installed, our team can supply and fit the system for you.
