Hi, problems.

Bled upstairs radiator around 2 weeks ago, now my pressure reads 0 at all times unless the system is on and the hot water tap is running at which point pressure reads about 1 bar.

Have gone round all rads and bled air out until water starts. Top rad in nursery seems to now be the only one that is cold at the top and no amount of bleeding rectifies this.

Pressure stuck at just above 0 when system is on. But will not power on when timer requests. Have to reset system at least twice for it to catch and heating to come on.

Tried looking at the three taps underneath boiler to let more water in but seemingly doesnt work when I turn on the \\\"water in\\\" tap.

Only time the pressure creeps up is if I turn the tap that shows an arrow pointing up next to a radiator. Obviously I dont want to leave this on as I am no expert as to the implications.

Now I am stuck, and need some help! any ideas? Oh, and I have checked as many taps and pipes as possible and no leaks anywhere.

Also, the radiators are making liquid noises at intervals now when they were previously quiet.

I am guessing this is my fault for bleeding the rad in the 1st place, but anyone have any ideas as to a fix before I call and engineer and spend money I dont have!

Thanks for any help in advance.

Can you post apic of the three taps you were talking about, one of them must be the filling loop that tops up your system

ACOperson · 26 Jan 2006

Basically you need to put water into the heating system then vent all the rads.

There should be a filling loop hose or pipe linking a central heating pipe and a mains pipe somewhere on the system.

When people have kitchens fitted they can sometimes cover the filling loop or box it in, so whenever the system needs filled (sometimes years down the line) they cannot do it.

Have a good look for it, if its not there call a plumber to put a new one in somewhere you can get to it.

Ill try and get a pic up later.

The boiler is actually outside of our house in an outhouse/shed and all taps you can get to - the only three with actual "taps" dont seem to do anything.

Ill get pics up which will probably help!

Cheers for the help so far - it is honestly appreciated.

i think the three taps ur talkin about are actually boiler isolation. the filling loop will be on the pipework. follow the cold pipe from the boiler(2nd from right) to a tee section.then follow branches off tee until u come to a flexi pipe or valve.

photos as requested! any help gratefully recieved!!

cheers

chrome braided hose is the filling loop, use a flat headed screwdriver to open the valve, and top up to 1 bar. then bleed rads and top up again. make sure you shut off valve properly....

ChrisR · 27 Jan 2006

You need to turn the screwdriver slot visible in the middle picture. Fairly near the blue lever. When it's in line with the pipe/hose the boiler will fill. Fill it slowly though, preferably when not really hot. Turn it off at 1 bar.

lol, that happened yesterday when I was playing "what does this tap do?"

A blast of cold water in the face taught me pretty quickly!

Off - the gauge might move when the pump starts.

grahaml · 27 Jan 2006

Not alot now would be useful if you were going to put a washing machine next to your boiler as thats what its for
