turned the wrong valve on ideal logic 35 combi boiler

[neilwaynes]

hey all,

we moved into our home in August last year and we got our boiler serviced right away (10 years old) with no faults noted. however when the days started to get cooler we started noticing that our boiler would lose pressure.

we called some folk round and they've not noticed anything jarringly wrong with it, so we've been re-pressurising it ourselves. however yesterday morning i realised id turned the wrong valve/tap and now it seems to have made it not hold any pressure for longer than 10 minutes.


i accidentally turned the tap right next to the pressure gauge and i can't figure out what this is for! i've tried googling, image searching, etc, and no hints as to what it's for, not even in the manual. any help would be appreciated - can we fix this problem ourselves or is this unfixable?

thanks!

Can you post a photo of it?

Can you post some pictures to show the layout?

Needs a photo. How old is the boiler?

The black lever next to the pressure gauge will be the flow isolating valve, it should point vertically, not horizontally.

If the gauge is far left and the lever turned was the first one next to it, then that's one of the system valves, that only stop the CH system flowing. Unless that valve it's dripping badly then it wouldn't have any effect on the boiler/system losing pressure. Presume you opened that back up again?

Look outside, below where the flue is, is there a bent copper pipe there and is that dripping water?

pictures, added some pressure this morning. but expecting it to drop.

There's no visible dripping on the boiler. We don't have a copper pipe but we have a vent? yesterday was dripping water but today there is steam.

As per @Madrab - that’s a Heating isolation valve, stops the flow or return. When the heating is on, do you notice if the pressure goes high?

There appears to be damage to the electric cable ,just behind the yellow lever ,or is the picture misleading ?
You have a leak somewhere that needs to be found. Continually adding water into the system to top up pressure is no good for your system.

That is just a ripped label/dust on label residue I believe! And we have had people come round twice now to try and help us with this and they say there's nothing wrong!

 

[terryplumb]

How often do you need to top up pressure ?
And what does pressure rise to when central heating has been running for an hour ?
The people you have had around shouldn't be invited back !!

 

[neilwaynes]

It needs to be topped up anywhere between a day to a few weeks, it's not very consistent. And I'm not sure, I've not noted that in the past and CH currently isn't staying on for an hour. We will look into someone else to come and have a look!

 

[terryplumb]

Why isn't CH staying on for an hour ? Is that because it is all that you want it to be on for?
How long does it be on for exactly,and what does pressure gauge read ?

 

[neilwaynes]

It's on for at least an hour usually but I've never looked at the pressure gauge on those specific circumstances is what I meant
