Finding a leak from your boiler can be worrying, especially if you are unsure of the cause or how serious it might be. Even a small drip should not be ignored, as water leaks can quickly damage your property and may point to underlying issues with the boiler itself. Knowing the right steps to take when you spot a leak will help you stay safe and minimise damage until an engineer arrives.
Steps to Take if Your Boiler is Leaking
A leaky boiler is more than just an inconvenience, it can affect heating performance and, in some cases, create safety risks. Acting quickly can protect your home and make repairs easier for your engineer.
Turn Off the Water Supply
The first thing to do is stop the leak from getting worse. Turn off your boiler’s water supply using the stopcock, usually located under the sink or near where the mains water enters the property. This helps reduce the amount of water escaping and prevents further damage to floors or walls.
Switch Off the Boiler
Once the water supply is off, switch off the boiler at the mains. This is an important safety step, as it prevents water from coming into contact with electrical components inside the boiler. Do not attempt to restart the boiler until it has been inspected and repaired by a qualified engineer.
Contain the Leak
Place a bowl, bucket, or towels under the leak to collect any remaining drips. If water has spread onto the floor, mop it up quickly to prevent damage to flooring or carpets. Keeping the area as dry as possible also makes it safer for your engineer to work when they arrive.
Identify Possible Causes
While you should not attempt repairs yourself, being aware of common causes of boiler leaks can help you understand what might be happening. Leaks often come from worn seals, corrosion inside the boiler, loose joints in the pipework, or problems with the pressure valve. Noting where the water is coming from can help your engineer diagnose the problem more quickly.
Call a Gas Safe Registered Engineer
The most important step is to contact a qualified engineer. Boilers are complex appliances, and only a Gas Safe registered professional should carry out repairs. Attempting a DIY fix not only risks your safety but can also cause more damage and invalidate any warranty or insurance cover.
Preventing Future Leaks
Regular servicing is the best way to reduce the risk of leaks in the future. Annual maintenance allows engineers to check seals, pipework, and internal components for early signs of wear, catching issues before they turn into leaks. Keeping an eye on boiler pressure and arranging timely repairs also helps protect your system.
