A small drip from your radiator might not seem urgent, but even the tiniest leak can lead to major issues over time. From rising heating bills to hidden water damage, identifying and fixing radiator leaks early is the best way to avoid costly repairs and keep your system running efficiently.
Spotting and Stopping Radiator Leaks Before They Cause Damage
Most radiator leaks develop slowly, making them easy to overlook until they become a bigger problem. Fortunately, with a few simple checks and timely action, you can catch issues before they escalate.
Start by checking for moisture around the valves, pipe connections, and bleed points. Look for rust marks, peeling paint, or damp patches under or around the radiator. A consistent loss of boiler pressure is also a common sign that something’s wrong in your heating system.
Once you've located the source, it's time to act.
Minor Leaks You Can Fix Yourself
If the leak is coming from a valve joint or the bleed screw:
- Tighten the connection carefully using an adjustable spanner.
- Wrap PTFE tape around threaded joints after draining and isolating the radiator.
- Use radiator leak sealant in the system for tiny internal cracks.
Always turn off the heating and allow the system to cool before attempting repairs. If you’re unsure or the leak persists, it’s best to leave it to a professional.
When to Call in a Heating Engineer
Leaks from the radiator body, ongoing drops in pressure, or visible corrosion should be assessed by a qualified heating engineer. They can isolate the issue, replace faulty parts, and ensure the system is safe and efficient. Regular servicing also helps prevent future leaks and extends the life of your heating system.
