Troubleshooting a Leaky Steam Radiator

If you live in an older house, you probably get your heat from a steam radiator in every room. These radiators are extremely reliable, but from time to time you may find that one is leaking. To prevent it from leaking in the future, you will need to do a little bit of troubleshooting before the system breaks down completely.

Check the Valve

The most likely location for a leak in a steam radiator is the steam valve. Located at the side of the radiator, this helps to regulate the amount of steam which is reaching the radiator in one go. If you spot the valve is leaking, you will probably need to replace it.

Check the Cap Nuts

Alongside the valve are the cap nuts. These bolt-like devices leak because they become loose over time. To stop the leaking, you can tighten this nut using a wrench. Hold the valve with one wrench, and turn the nut with the other.

Check the Vent

If neither of these solutions has worked, check the steam vent. These can become blocked or corroded over time, and this causes them to leak. If the vent is blocked, you will need to replace it with a completely new one, and this should solve your leak.
