How to Stop a Leaking Water Pipe: Methods Overview

It is usually best to call in a professional plumber if you are not experienced or confident with tackling the issue yourself, as trying to fix a water pipe without the knowledge or experience can result in further damage being caused.

If you need a simple, temporary fix that can tide you over in the short term before implementing a long term solution by a professional, then there are a range of materials and solutions on the market to help with that such as:

Plumber’s Putty

For pinhole leaks or leaks at joints, plumbers putty offers a quick and simple fix. Turn off the water supply, clean and dry the area, then mix and apply the putty over the leak. Smooth it out, let it harden fully, and turn the water back on to check for any remaining leaks.

Pipe repair clamp

A pipe repair clamp consists of two metal plates and a rubber patch which are placed over the hole and around the pipe, they are then tightened together with screws. This is a simple, quick and solid solution for repairs to pipes made of steel, copper, asbestos cements, cast iron and plastic pipes.

Pipe repair spray

Pipe repair spray is ideal for temporarily repairing leaks in pipes, guttering, drains, windows and roofs. It seals by seeping into the cracks and holes caused by the burst. A good pipe repair spray remains flexible and pliable for years and protects the surface from corrosion. Once dry, you can paint it any colour.

Pipe rubber tape

Pipe repair tape is a quick, low-cost way to temporarily seal a leaking pipe. Turn off the water and wrap the tape tightly around the leak. It works well on pipes, hoses, and cables. However, if the leak is due to pipe corrosion, it may signal a bigger issue—consider calling a professional to inspect the system.

What could cause a pipe to leak?

Temperature changes

During cold months, pipes can freeze and contract. When they thaw and expand, it can create gaps that lead to leaks.

Hard water

Minerals like calcium and magnesium build up inside pipes, weakening them over time and causing leaks, clogs, or cracks.

Deterioration

As pipes age, rust and corrosion can wear them down, eventually creating holes or weak spots where water can escape.

Bad workmanship

Improper installation or repairs by unqualified plumbers can cause loose joints or material issues that lead to leaks.

Clogs

Hair, grease, and debris can clog pipes, causing water to drain slowly or back up into sinks, showers, and toilets.

Saving money on the maintenance of your water pipes

Hard water affects your plumbing system by creating a buildup of limescale in the pipes, which can lead to decreased water pressure and result in clogs. Stresses on the pipework can also cause bursts and leaks, which often means costly repairs.

As well as risking expensive damage to your plumbing pipework and appliances, hard water can significantly raise the energy costs of heating water through your boiler, whilst forcing your boiler to work harder and therefore reducing its lifespan.

One of the best ways to prevent damage to your water pipes and save money is to first combat hard water by having a water softener installed in your home, which could save you a lot of money in the long term.

How to stop a leaking water pipe based on the situation

While it’s always advisable to call a qualified plumber if you’re unsure or inexperienced, there are temporary solutions you can use to manage a leaking pipe safely. Acting quickly can help minimise water damage and reduce the risk of costly repairs. Whether it’s a copper, plastic, or radiator pipe that’s leaking, there are practical steps you can take to keep things under control until professional help arrives.

With water in it

If water is leaking from a pipe with water still in it, turn off the main supply first. Dry the area, then use a repair clamp or silicone tape to help contain the leak until a plumber can make a permanent fix.

Radiator pipe

If your radiator pipe is leaking, turn off the heating and close both radiator valves. Dry the area and apply leak sealant or repair tape as a temporary fix. If the leak persists, contact a professional to prevent further damage.

Plastic pipe with water

Shut off the water supply to relieve pressure. Dry the area, then wrap the leak with plumber’s tape or use a pipe repair clamp. These quick fixes are temporary, replacing the damaged section is the best long-term solution.

Copper pipe

Turn off the water and drain the pipe to stop the leak. Use a repair clamp or epoxy putty for a temporary fix. If corrosion is the issue, replacing the damaged copper section is the best long-term solution.

Conclusion

While quick fixes can help manage leaks in the short term, prevention is always the best approach when it comes to protecting your plumbing. One of the most effective ways to reduce the risk of pipe damage is by tackling the root cause: limescale buildup from hard water. Installing a Culligan Harvey water softener helps to prevent this buildup, keeping your pipes clear and reducing the strain that often leads to cracks, leaks, and bursts. It’s a long-term investment that not only protects your plumbing but also brings added benefits throughout your home — from longer-lasting appliances to softer laundry and skin.
