I recently removed an internal wall, and also replaced a radiator in the new (downstairs) room. To do this I removed the pipes, cutting them close to the junction under the upstairs floorboards, and installing two isolation valves, so that I can continue to use the central heating during the demolition/plastering/decorating, then when I’m ready to install the new rad, simply attach the new pipes to the isolation valves, and fill the new rad without having to drain the system again.
However, one of the (Compression fit) isolation valves is leaking. Not badly – a pad of tissue paper is sufficient to contain the occasional drip. I’ve applied some leak-sealant adhesive – twice – with no success. Is there any other way I can seal the leak, without draining the system, removing the valve and starting again? My CH is a pig to bleed, and I really want to avoid draining it.
Thanks!
