I have, over the years, removed many radiators and occasionally one (inlet
or locksheild) will weep or drip. I usually run to my plumbing box and make
something from my bits and bobs. Is there anything on the market that will
screw onto the rad valve to act as a 'stop end'? There must be something
but I can't find one (or two incase both sides drip!)
A compression stop end fits on the radiator side (minus olive), so I assume
a compression straight coupler with a blanking disk in would do the valve
end. Being compression fittings, they are reusable.
I found a picture of a blanking disk on toolstation:
Screwfix don't do them, so I don't know if your local B&Q or plumbing
Hope that helps
Used to use copper coins as blanking discs - can't remember denomination but
a quick sort of a handful of change will show if any fit a compression
A coin behind the nut should blank it off O.K. (but beware of the crime of
defacing a coin of the realm).
Are the older fittings 1/2 inch BSP fittings? (The same fittings as an
outside tap if I am correct). I used a connector with a 1/2 inch BSP thread
on one side and a 15mm a compression joint on the other side which was
connected to a piece of pipe with a push fit stop end on. It was all I had
but it worked.
I think you'll find it's 3/4" BSP, same as a washing machine connector (and
most outside tap threads)
Well if it is 3/4" BSP (same as a washing machine inlet hose), then a
hose could be connected to both valves, sealing both ends at once, and
these hoses are available in 1.5M and 2.5M lengths, which should be
enough for most radiators.
