Radiator leaking
A radiator leak can drop boiler pressure and damage finishes if not handled in time.

Possible causes
- loose or faulty air vent
- flow/return valve leaking
- old fitting or gasket
- loose side plug
- perforated or corroded radiator body
What you can do
- place a container under a small leak
- close radiator valves if possible without forcing them
- photograph the exact leaking point
- note whether boiler pressure drops
Service
Depending on leak point, repair may require tightening, gasket, new valve or radiator replacement.
