Top up my combi boiler...

[jdepaauw]

I have recently bled my entire central heating system of water in order to replace a radiator valve (and was quite chuffed with myself at achieving as it was my very first plumbing experience). After the successful valve replacement, however, I have gone to switch my combi boiler back on (water mains on already) and there is no water pressure on the dial. The instructions on my boiler say to top up water in boiler but suggests calling an engineer to do this!!! I'm not sure this is necessary!!!! How do I top up my boiler- I have some information which talks about a filling loop and a valve to slowly increase pressure... can anyone clarify exactly how to do this for me please?

If you can follow this, OK; if you can't get a professional to do it.

see this thread //www.diynot.com/forums/viewtopic.php?t=3592&sid=9b228f196e90ab27435a6aad1fff39b3 towards the end.

There's a way to make these references less cumbersome but I don't know how.

If you do a search for 'filling loop' you will find this subject has been covered a few times recently

Thanks. After reading alot more and feeling a bit more confident about where the valve was I did as instructed. My central heating system is now up and running perfectly- phew!
