Hi everyone.
I have had my Central heating on for a while but I switched it off last night.
When I got up this morning there was a patch of water under the boiler and the pressure had dropped but not by much.
I have established it is dripping from the pipe with a red tap marked CH flow.
Any ideas what may be causing this?
The boiler was serviced last May if this matters.

Thanks in advance.

Could be a number of reasons, can you upload a photo for clarity

Sure. Thanks Stu.
The red tap on the left was the place it was dripping from, more from the pipe connected above the tap as opposed to the actual tap.

I turned it off this morning after being on for almost 24 hours and there has been no dripping today.

Get it stripped & cleaned & use some plumbers mait which is a non setting compound,
Goes on the threads, roll it in your hands like you used to make plastercine worms.
Will seal it no probs,
Trim off excess after tightening up.
Job done

Expansion and contraction of the pipework can cause leakage is the pipework bracketed ? it looks like the leak is from the flow connection above the valve this has a fibre sealing ring which has possibly failed or it may simply need a tighten ? Good luck keep safe . Kop
