When it comes to maintaining your home’s heating system, ensuring your radiators are in top working order is crucial. One of the most common issues we encounter at MPK Engineers is leaks in radiator valves. While they may seem minor at first, these leaks can lead to bigger problems if left unchecked. Not only can they increase your energy bills, but they can also cause damage to your home. Here’s why it’s important to check for leaks regularly and how you can do it yourself.
Why Checking for Leaks in Radiator Valves is Essential
- Prevent Energy Waste:
A leaking radiator valve can lead to unnecessary water loss, which means your heating system has to work harder to maintain the desired temperature. This inefficiency increases energy consumption, causing your gas bills to rise. Catching leaks early helps prevent energy waste and keeps your system running efficiently. - Avoid Property Damage:
Over time, even a small radiator leak can cause water damage to your flooring, walls, and furnishings. Moisture buildup from leaks can also lead to dampness and mould growth, which can be harmful to your home and health. Regular checks can help you catch leaks before they cause significant damage. - Prolong Your Heating System’s Lifespan:
Radiator leaks, especially if ignored for too long, can lead to more severe issues like pressure loss in your heating system, corrosion, and breakdowns. Fixing leaks promptly can save you from costly repairs or the need for an entirely new heating system.
How to Check for Leaks in Radiator Valves
Checking for leaks in your radiator valves is a simple process you can perform yourself with minimal tools. Here’s how to do it:
- Visual Inspection:
The first step is to take a close look at your radiator valves and the surrounding area. Look for any signs of water droplets, rust, or discolouration near the valve. Water stains or damp patches on the floor beneath the radiator can also be signs of a leak. - Touch Test:
Use a cloth or tissue to gently wipe around the valve area. If the cloth becomes damp, it’s likely there’s a leak. Be sure to check all visible joints and connections on the valve for any moisture. - Check for Drips:
Some leaks are slow and difficult to spot, so it’s important to look closely for any tiny drips coming from the valve, especially around the base where it connects to the pipe or radiator. If you notice any, tighten the valve slightly with a wrench, but don’t overdo it as this can cause damage. - Pressure Check:
Your boiler’s pressure gauge can indicate a leak somewhere in the system. If the pressure consistently drops, it’s a sign that water is escaping, possibly through one of your radiator valves. You may need to repressurise your boiler, but it’s essential to find the leak first.

Sometimes, a leaky valve emits a hissing sound, especially if air is escaping alongside the water. This can be a tell-tale sign that the valve is not functioning properly and needs attention.
What to Do if You Find a Leak
If you find a leak in your radiator valve, don’t panic. In many cases, tightening the valve or replacing a worn-out washer can solve the issue.
