How To Fix A Leaking Radiator Valve

How To Fix A Leaking Radiator Valve

Instructions

Like taps, radiators can develop leaks. Fortunately, these are usually really easy to fix. If you are not sure how to do it, don't worry, because we at Homeserve are here to show you.

Step 1:
Before you start - get a spanner, some paper tissue, and some PTFE tape.

Step 2:
Water leaking from a radiator valve might be seeping from around the valve spindle. However, when the water runs round and drips from the valve's cap-nut, it's the nut that often appears to be the source of the leak. Dry the valve then hold a fresh piece of paper tissue against the various bits to work out exactly where the moisture is coming from.

Step 3:
To stop a leak from a radiator-valve spindle, tighten the gland nut with a spanner. If the leak persists, undo the nut and wind a few turns of PTFE tape down into the spindle.

Step 4:
If the cap-nut is leaking, tighten it gently with a spanner. In most cases this will stop the leak. However, if the leak persists, you will need to replace the valve. See "How To Replace A Damaged Radiator Valve" for advice on how to do this. Job done.
