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).
This is true of the more recent rad valves that use compression fitting on
the rad side.
However, most rads out there have the older style much larger coupling.
I haven't come across a gadget to stop those off.
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.
