Cannot top up boiler pressure

[Gravy]

Hello,

(Images removed. Please add them in a reply post directly to the forum.)

Please see the linked gallery with more details about the problem. Basically I can't figure out how to top up the pressure. Any help would be much appreciated! For some reason I can't get the imgur gallery images to stay in order but hopefully it still makes sense!

Thanks.

I had more details in the imgur gallery but it seemed to get removed for some reason. I'll try posting it again

Are there any other details which would be helpful to know?

Ah, I'm new to the forum and didn't realise you could upload pics that way.

My boiler showing the low pressure gauge

An overview of the pipes below the boiler

A silver hose that I thought would attach to somewhere to increase the pressure

It doesn't screw into the fitting below it

It can't reach the fitting in the bottom right

A view of the underside of the boiler. Maybe there is somewhere here to increase the pressure?

Any help would be great!

The braided fill pipe has been fitted the wrong way round.

Check first that the non return valve is working correctly by opening the isolating valve on
the loose end of the braided pipe.

Remove the filling hose from the top after the check valve and fit the isolating end to the nut (close the isolating valve.

You can now fit the loose end to the lower isolating valve.

By opening the slotted valves you can now bring your system up to the required pressure.

Make sure both valves are closed when finished.

Check that the check valve is holding by opening the valve on the flexi eg the end that isn’t attached to anything

Remove the valve from the end of the flexi (the end that isn’t attached to anything)

Then put that end on the valve on the other piece of pipe and tighten up

You should now be able to fill your system

I'll have a firkin or two of what this one is on!

What is to disagree with what Heliotrope Smith posted?

When I read your post comes out with the same problem he’s got now

I read it as

Check the dcv is working via ballofix

Remove compression flexi off the dcv

Install the valve on the other end of the flex where the compression nut is

Now install the other end onto the valve one problem he’s left with a female compression both ends like he’s got now as the flexi isn’t swivel / loose but both ends

???

Oh dear! Oh dear! This site is going to the dogs!

Get sober and read the post again!

Just need to reverse the filling hose!!!!!!!!!!!!!!!!!

 

[Gravy]

Thanks Heliotrope and ShaunCorbs, with your advice I fixed it!

I took the fitting off the end of the flexible pipe, I'm not sure why it was on there.

Then it connected to the fitting below and I could increase the pressure.

It's in the green now! Thanks again!

Good thanks for the update

That's a bit high if the boilers not running. Somewhere between 1 and 1.4 bar when the boiler is cold.

 

[Gravy]

The boiler was running when I topped it up. However it has increased a bit further with the boiler being left on for longer and is now around 2.2 bar. How do I reduce the pressure?

 

[ShaunCorbs]

2.2 bar is fine when fully hot / warm

 

[Gravy]

That's great, thanks.
