hot water & radiator problem?

[kev_1911]

hi all,advice and help needed please.a few weeks ago i moved a hot water cylinder from the airing cupboard to another cupboard next to the bathroom in total about six feet,i marked all the pipes and reconnected them to the same ones after extending,now my problem is that when i put the boiler(ideal mexico) in hot water only the upstairs rads are getting hot as well,there is no stat on the cylinder so i think its a c-plan? it worked fine before the move,so any help or advice please on what is wrong and how do i fix it.
many thanks.

On the heating flow pipe from the boiler usually within a couple of feet there should be an antigravity valve looks like a brass socket about 3 inches long.. When you have drained system a bit of dirt has prob got into this and stopping it working properly.. for all they cost just replace it cost about a fiver
