Where is the leak coming from?

Your radiator could be leaking water for a number of reasons. To find out where the leak is, dry the surface of your radiator, the radiator valves and any visible pipes with towels. The leak will be coming from the part that remains wet.

If possible, turn off the valves to the radiator. You can do this by screwing them down (clockwise direction). This may slow or stop the leaking water, until a qualified plumber or gas engineer can repair the leak.

You can use towels, dishes, bowls etc. to contain the water leaking from the radiator, and minimise damage to your home.

Leaking due to corrosion

One reason your radiator may be leaking is because of corrosion. Unfortunately, this means it will need to be replaced. Talk to a qualified plumber or gas engineer about getting a new radiator fitted.

If a leak is caused by corrosion, this is usually an indication of an underlying fault with the system. Contact a qualified plumber or gas engineer for advice.
