We turned off the valves to remove the cloakroom toilet and sink when we turned on the valves no pressure from the hot taps upstairs hardly anything coming out in the kitchen intermittent water with what seems like air think it could be an airlock somewhere but stuck with what to try now please help

if you turned off the main hot valve with a red handle in the cylinder cupboard they can break internally and will need replacing a sign of this is the handle keeps turning if it seems ok try to link the hot and cold supplies (either tap to tap or pipe to pipe) and turn both on for a minute or two this should blow the airlock out
