Gas boiler

[sleeveless]

I have moved into a property with a gas combi boiler When I went to set the timer I noticed the pressure(?) gauge was on zero I seem to think I need to let water in to bring it back up.... firstly is this right? If so where would I find the stopcock? It isn't anywhere near the boiler
Thanks

We have had a similar problem a few weeks ago, if you look under the boiler there should be a tap or leaver that will open the water supply into the tank. we needed to let it run for about 10 minutes but you will see the pressure rise, when it get to about 1 then stop it and you should be ok. I must say though that i'm not saying this the correct procedure but it worked for me, if somebody can come up with a better responce then please do

Thank you homethegrea I thought it was something like that... trouble is there is something that looks as if you could fix a handle to but there is no handle (if you follow) and I'm concerned I might do something wrong :0(

I mislaid the removable tap on my combi, I used a flat bladed screwdriver to turn the recessed screw. Mine was anti-clockwise, Just turn the screw gently, and you should see the gauge start to rise. Stop on 1 bar. As homer said it is located under the boiler. Of course I then found the tap!!!

Hi, under your combi is usually a flexible pipe called a filling loop. Its function is to top up the water in the central heating if required. It connects the incoming water mains supply to the return pipe of the central heating. The filling loop should be removed when not in use (water regulations I think).
Connect the filling loop, (you can buy one in B&Q for a few pounds if needed), and then open the isolator valve on the mains side. Water will enter the central heating system and pressurise the system. Aim to have the guage reading between 1.0 - 1.5 bar with the central heating pipework cold. Depending on the type of isolator valve fitted it may need a screw driver to open or it may have a plastic handle fitted.
Once sorted keep an eye on the pressure because if it needs constant topping up you may have a leak in the central heating pipework somewhere.
Good luck.

barnet boy thank you so much... I checked and you are quite right the hose is there and disconnected. Heaven knows what would have happened if I'd turned the large nut thingy I thought was a stopcock!!!
Thanks to everyone
