I am stripping out the downstairs bog and there are plastic isolation valves
on the hot and cold water to the hand basin.
They have markings on which look like JS but the font is naff.
They have long bodies and are marked 65 degrees c max.
Where the pipe enters the valve end there is a moving collar, indeed the
pipe can rotate within the valve without leaking.
I will replace these during the re-furb but wondered whether it should be
possible to remove the downstream pipe.
I have tried pushing the collar towards the valve to release the pipe (as
with hydraulic/air fittings) - the collar appears to move, but the pipe
Anyone used these and know if they are demountable (they don't appear
re-usable, not that I would anyway).
You push the collar all the way, so that it's flat against the valve
body, then pull the pipe. They are demountable and reusable, but new
ones are always a good idea.
...but they are the worst heap of junk I have ever used. They are made
of plastic which is about as hard as chewing gum (used). So when you
try to turn the valve with a screwdriver the little groove just
disappears. Avoid. (And I generally like Speedfit - wait till Dr
Drivel comes along!)
Yes, JG, that's the boy!
Have tried pushing the collar to the valve to withdraw the pipe with no
Don't want to be too brutal in case the live side of the valve takes over!
To be fair, neither of them leak, though I don't know how long they've been
Screw slots are showing serious signs of wear.
I'll wait till I've got replacements and turned off water before
The fluted nut type thing on the valve below the collar unscrews by
about 1 or 1 1/2 turns. You can then push down the collar to release
the pipe as per air fittings. It's a locking feature to prevent the
pipe being accidentally released.
You can also get half-moon shaped clips which fit into the gap
between the valve and collar, to stop the collar being accidentally
pushed down. If those have been fitted, pop them out of the gap first.
Clear? No, probably not.

If there's any misalignment in the pipes it can be a pig to demount the
fitting. Also on fittings that have been in place for some years corrosion
can build up on the copper pipe within the fitting so that although the
fitting rotates it doesn't want to pull off. The solution, as ever, is to
use a bigger hammer :-)
