Hi there...

i bled my 1st floor radiators earlier as the tops were cool but
the bottoms were hot.

I cant however find the place where I need to top up the pressure
in the system.

There is a potterton combi bolier in the corner of the kitchen,
and a flexcon pressure gauge under the sink whic is nearly on
0bar, but i cant see a way to add more water into the system to
bring pressure up.

Any idea or anyone familiar with these brands?

I suspect I have left important info out that might help to hlep
me, so please let me know!

Look for a steel-braided flexible hose with a valve on it. Should be
somewhere directly beneath the boiler.

With one eye on the pressure gauge, open the valve and top-up to 1 bar.
