oh and u made me lol..lol ...when you vent radiators ..its not "gas" that's coming out ..its air...lol

I thought it was a gas, water and air and metal mixing makes hydrogen and this is a gas isnt it?

This is why we add inhibitor to slow this reaction down.

just to be pedantic

Hi Michael
Lots of advice & comment on this but if you will take a last tip from your uncle Chris, get somebody in to change the rad valve as it is leaking & the system pressure will drop again, over a short time. At the same time get them to do a service on the Megaflo un-vent cylinder, these need to be looked at from time to time (manufacturers say once a year just like boilers) as they can be potentially dangerous if things go wrong. I am not trying to scare you & the photo is not that clear but it does look as though it does not comply with Building Regs G3 & if it has not been looked at in a while it would be a good idea to do the two things at once.

i really didn't even want to reply but ..couldn't help it...yes we as engineers know that but some customers think gas goes through the whole system...hence why i mentioned my customer last week and im quite sure gas safe would have a law for all persons venting radiators to have rooms well vented and no smoking while doing it as well as ive never heard any say " hey m8 go vent those rads of hydrogen" ...that's not pedantic mate ....you just need to stop drinking the inhibitor and add some thing mellowing in your rizla....chillski man chillski..
lol lol...
