Connecting filling loop for Procombi A32 boiler

[ellieb246]

Hi, I’m trying to top up the pressure but can’t work out how I’d go about connecting a filling loop because the valves are weirdly shaped and not what I’m used to. Any help appreciated!

Can you remove the white panel ,that's below the boiler,and show us another pic ?

This is what’s behind it so have realised there’s already a filling loop in place, my mistake, but when I turn the isolation valve switch nothing happens, any ideas?

Is it the black handle ( looks like it may have white paint on ? ) ,that you have turned ? It's in the closed position in your pic.

There is also the possibility of a second isolator at the other end of the Flexi!

Edit - sorry, no, I can see the other end, DOH!

Yes, that’s the one I turned on and there’s no water coming through. The annoying thing is I have a new filling loop and valve I could replace it with but because of the way they’ve installed it I can’t unscrew it.

Also, there’s definitely only the one isolation valve but ty!

I know it's a silly question, but does the screw in the centre of the handle also turn, when you move the handle?

 

[ellieb246]

Yes, screw is turning with it, should it be?

Yes, it should.
Sometimes the handles can spin, and not turn a stuck valve.

Can you undo the Flexi on the valve side?
That side is the cold water feed side - if you can undo the Flexi there, you can very carefully check the valve is working.
If it does operate correctly, then it's likely to be the non-return valve at fault.
Which means you'll need a spanner to remove the valve - no need to undo the Flexi on that side.

Take the screw out ,pull off the black handle,it may be worn or cracked and not turning the valve spindle ,use a spanner on the spindles square end.

Hi so I finally managed to get hold of a spanner but the valves themselves still won’t budge. Took the loop off and now hot water is coming out the end and can’t see why. The boiler is off and I can’t see another switch valve at the other end, any ideas please?

If you can't operate that valve (black handled one), with a spanner it needs replacing.
As water is coming out the flexible hose ,the none return valve will also need replacing.
