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!

thanks.

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.

If it's anything like my pressurised system there should be a lever
switch on the pipe work, (in my case near the pressure gauge) which you
turn to allow additional water into the system, when you reach the
operating pressure (in my case 1 bar) turn the lever back.

there is a red plastic cap on top of the gauge, with arrows pointing in an
anti clockwise direction, yet if you turn this, it acts like a cap for a
medicine bottle; it keeps clicking round and round.

I found that turning it slowly, and holding it works, bu the pressure drops
when doing this.... not goes up like i was expecting. i must be doing
something wrong?

the only braided hose i can see nearby is for the sink, i dont think there
is a lever nearby either...

Hi,

managed to find all of this, was hidden away and had no lever!

got the pressure up, bled the radiators, the pressure dropped again so
topped it up to 1.0 bar.

now the boiler turns on, then goes off after approximately 30 seconds.

can't think why, any ideas?

That is the pressure relief valve. It's designed to open
automatically if the system pressure should go too high. Turning it
is a test function which releases some water and so the pressure will
drop. Just for reference.... Doing so is not a good idea because
you can get bits of crud from the system stuck in it and provoke a
small and steady seepage which is difficult to fix.

You need to look further. POssibly there or somewhere within
reasonable distance (a few 10s of cm) of a cold mains water supply,
there should be a threaded fitting about 25mm across. Nearby, there
should be a similar one on the cold mains supply. They look rather
like washing machine valves typically. There should be a braided
hose to connect the two, although that is supposed to be removed after
use so may have been lost.

Have a look on www.bes.ltd.uk

Then search using 11354 as a prodcut search (not part code)


http://www.bes.ltd.uk/products/109.asp

You are looking for some kind of arrangement like that or perhaps
something like 8148, 8165 or 15583 (further down the page)

The hose may have gone missing, in which case you'll have to buy one.
Plumbers merchants or B&Q Warehouse have them.

Airlock? Either in the boiler or at the pump. Just guessing.
