airlock in vented system

[jhon lennon]

tried everything that has usually worked for me in the past lockshields screwed down upstairs bled pump and rads the thing is getting on my nerves now added a rad to the conservertory all the rads heat up bar one in the hall any suggestions would be appreciated the job was a pig to do had to move all kinds of baby toys out of the bedroom to lift floorboards and the custormors dog followed me around all day i broke my drill getting through the wall one of them jobs you regret taking on so had a huge cob on before the air lock problem came about gonna have to go back with a fresh head on and try again

Sleep on it mate, you know the solution but just encountered 'brain freeze' brought on by frustration.

Did you take the rad off, check that there's a flow through both valves Jhon lennon? Maybe a way forward if not

you could close and drain the problem rad, then open each side in turn to find the problem pipe.
then put a wet vac on it a suck the air out to see if that helps

Was the dog good lookin ? :001_icon16:

the dog was better looking than his wife lol and the rad with no heat was getting it in at flow and return filling and vented it just no heat so the lock will be in the main circuit i suspect probably on a tee i will suss it was just being lazy and was wound up so i was hoping you good chaps would do the thinking for me vented are murder for air locks come across it before just never had one as stubborn as this before and it did my head in good nights sleep and i will suss it if not i will just have to run away with the dog

Just stick a hose on each valve, one at a time & let it run for half a min or less & you will probably see the flow of water splutter due to air from the airlocked pipe. Should always work, but a pain. Before I would try that I would turn every other part of system off, rads & cylinder (if fitted) & give the pump & boiler a run for few min.
Maybe if heating is turned on it will clear itself by tomorrow!

didnt try the hose pipe trick but did everything else going back in the morning but stuck for time cos i have another job on in the afternoon and when you have time issues the job always plays up doesn't it some jobs just try you don't they and this has been one of em everything about it was awkward doomed from the start the merchants i always use didn't have the reducing tees i needed and i ended up going to screwfix and i don't know why it is but nearly every time i buy from them the job is a pig just to top it off every time i got set up and ready to do a bit someone in the house either needed me to move my car so they could go out or tools so they could use the bathroom or get out the back door or just mither me in some way or other just one of them days who said being a plumber was easy
