I have water leaking from my bathroom radiator valve this morning, just dripping but constant. It's a straight rad valve and from catalogues looks like a Hudson Reed HT 320 - it may be a look alike though. The water is coming from under the flow regulator handle, the connections to the copper feed and radiator itself are fine. I guessed that I could remove the the regulator handle and perhaps tighten the nut underneath but so far can't get the handle off. Anyone know how it's fixed?
If the rad valve is unfixable then I think I have a bit of a job on because one of the isolation valves to the rad isn't working and looks like a real pig to get to and replace. (Bath out and oak and ply floor up to get to the lower compression joint)
Most valves have a packing nut on top. It has a washer or packing material inside that compresses around the valve shaft, Tighten the nut a bit, Usually only a fraction of a turn is needed to tighten things up. It should be loose enough that you can still turn the valve, but have friction from the packing material.
Thanks Just Bill,
I did get the valve apart but there was no packing nut, just a circlip so no adjustment. Finished the job about an hour ago - both rad valves and both isolating valves. Just got to repair my floor now.
