Hi, we have removed a Honeywell radiator from a room and don't intend to fit a new radiator just yet. THe pipes which supplied the water to the radiator are still sticking up through the gaps in the floor. Both of the valves at the top of these pipes have been turned off, but there is the tiniest amount of water which is continually leaking from the end of the honeywell trv(???). Would brass blanking caps and washers ensure that it wouldn't leak anymore? Until such times as we decide exactly what to do with the pipes. ANy advice would be appreciated
