I have found a small leak from a valve on the cold water inlet to my boiler. It is on the boiler side of the main shut off valve for the filling inlet.
I assumed at first glance it was an isolation valve but would have expected a different type of head on it (slotted rather than hex bolt). Is it a non-return valve? Other?
Either way I am assuming that it will need professional replacement.
Thanks in advance. Couple of photos attached.
