Any Heating Engineers Plumbers on here? Advice required!
Hi, Noticed on one of my Radiators in the bedroom that theres a small leak coming from the TRV valve on the Rad.
Its only a tiny drip here and there that seems to come and go (i guess when i put the heating on it starts). The drip is coming from around the Knurled silver ring right under the Thermostat control. The silver ring was very loose so i tightened it up but can still feel it wet occasionally.
Whats the likey cause here?
