With a gauge.
That's hard part.
I know
I have one of these and it's not easy...

surprised that you had the time to be on here this weekend APOD thought you would have been on the **** big time
Yesterday was! Today a sobering up exercise!
Nice one mate never made it this year if over next year will give you a shout and meet and have a few
Update.
Shut off flow and return pipes and mains water.
Emptied boiler via the drain point until zero.
Somehow got the pump on and pumped for a bit (my arm was dead) water was still trickling out of the drain point then the pump got tight and started holding pressure. Pumped to the required pressure and now filled it all back up again.
Fingers crossed this works. If not I guess I'm looking at an external vessel which would be a damn sight easier than pumping the existing one.
Thanks all for your help even if some of you are a little tender after yesterday.

Update 2.
Heating has been on for about an hour. Pressure started at 1.2 bar and rise to 1.8 bar but seemed to stay at that, before it was way up over 2.5 bar. I've just switched the heating off and will let it cool. There is still a wet patch outside but the problem is that the overflow pipe and flue are in line with each other so I don't know what one the discharge is coming from.
If the pressure drops again overnight do I assume I need the external expansion vessel or with no water coming from the existing do we assume it's working OK and it's another issue?
Thanks again.

your condensate pipe should go into a drain or a soakaway but sounds like you have sorted your problem
Sorry I meant overflow pipe from the PRV. It's directly under the flue on the gable of the house.
The pressue was exactly on the red mark last night before bed with no heating on overnight. So close
On Sunday night when I isolated the system and diconnected the filling loop I noticed there was a leak from the NRV (I'm guessing this is what this is). Would this cause the pressure to drop? I was thinking that when the filling loop is connected the system stays sealed or maybe thats not the case? Will I replace NRV or can I buy a cap to screw on the end?
U have blocked up heating system
What u need is a gas Enginer to carry out a ful service or some here might say a full strip down and change
-a Prv,
-new ex vessel or recharge,
-fit newpressure gauge or or use an air compressor to clean the tube
-check the divert valve if its leaking
-by-pass
-Strip the pump check its performance/ clogged manifold
-And also see if u need a
Powerflush
-and fit a Megan clean.
Just to mention a few
Thanks for your reply.
The whole house was fitting with new pipework and rads about 3/4years ago because previously it had those microbore pipes that kept blocking.
On your list above I've already changed PRV & recharged the existing vessel.
The dropped dropped every so slightly last night, I'm hoping someone can advise on the leaking NRV?
I've just got in and the pressure has dropped another 0.1 bar. The heating hasn't been on all day, hasn't been on in 24 hrs. There is a very small wet patch outside, what would be causing this? What's my next move (besides getting an engineer out)? Thanks for your help so far.
I've just disconnected the filling loop and the NRV is dripping. Could this be causing my problem? Is it worth replacing this or when the filling loop is connected does it not make any difference?
Edit - I think it's a double check valve that's leaking.

I isolated the boiler from the central heating pipework and left it overnight and the pressure dropped so its definitely dropping from the boiler. Can this still be the expansion vessel even though there was no water coming from the valve? Any other suggestions?
Sorry for all the questions. I'm a single dad who sees his daughter 2 nights a week. I can't afford costly repairs especially so close to Xmas and would like to elimate all I can before paying for someone.
