How to fix a pinhole leak in a central heating radiator?

FAQ banner image

A quick, simple and cost-effective means to fix a pinhole leak in a central heating radiator is to apply a two-part epoxy putty to the affected area.

The putty will mask the small hole and prevent the radiator from leaking.

This method isn’t recommended if larger holes appear on the radiator. A replacement radiator would instead be required in such an instance.
