I close both sides of the radiator, but it never seems to isolate. When I open up the bleed valve, the water just keeps dribbling out and never stops. Whats going on?

[@HouseWarm]

One or both of the valves are faulty, you'll need to drain the system

@@HouseWarm would it be possible to just depressurize the system, and do a quick valve change without too much water coming out? upstairs radiator on combi boiler

[@HouseWarm]

Yes, i do it all the time

@@HouseWarm Okay cool, so no need to fully drain the system if just doing one upstairs. Cheers for the replies
