Is it me, or do service valves always weep a bit?

I do a lot of change taps/change sink jobs and always seem to find the
service valves (if fitted at all) weep and I end up working with wet arms!

Got to the point where I've just made up a couple of 2" lengths of copper
pipe with stop ends & compression nuts & olives so I can blank off the
service valves.

Cheap ones do - especially in hard water areas.

I have similar stubs for fitting to radiator tails for much the same reason!

Are these not supposed to have a correct orientation? Maybe the leaky ones
are the wrong way round. The one under my sink is.

As to useful connectors I made a length of hose up with 3/4 BSP connections
so that when I remove radiators I can bypass the leaking rad valve without
having to drain the system

The hose idea is one I have used - I also use it to flush the system -
usually by screwing it into one of the top blanking plugs (yes - old
radiators) and opening another to drain the system.

Sorry to be a bit dim, but can you explain how that works?


Sometimes when I remove a radiator one of the valves still leaks even when
turned off (and in the case of TRVs with no locking cap I worry about the
temperature dropping and the valve opening). It is just a hose with 3/4 BSP
connectors (and two 1/2 BSP adaptors if needed) that fits between the two
rad valves. I really should have used blanks but did not have any at the
time so made the hose up instead. This hose also serves the dual purpose of
allowing me to drain the system later and replace the dodgy valve.

Oh, I see. Sorry, I thought you meant you had some demon scheme for
changing
the valves without draining/freezing. We have had to have a series of TRVs
changed over the last few years & I'm always looking for easier ways of
doing them.

Swap them live, it takes some balls but I have done it. No guarantees about
the mess but if the room is getting decorated!!!

A mate of mine wanted a new feed to a radiator. The easiest way to do it
was from the tails of the rad in the adjacent room. So I said the
simplest way is to have a service valve ready, chop the pipe with a pipe
cutter and then shove your valve over the pipe. It was a vented system
with only 20' head, so I told him he would not lose much water.

I was working on something else in the house when I heard the swearing.
Went to investigate and found black gunk all over the floor, walls, and
even ceiling! Seems he had a spot of bother. I said, I would do the next
one. First clue was he commented on the fact that I had the service
valve already assembled - with nut and olive in place! It seems he had
cut the pipe, forgot to stick his thumb over the end and then set about
placing the back nut on the pipe first, then the olive, then the valve.
Then found he had left the spanner out of reach!

Did he let the central heating cool down first? If he did it was the only
thing he got right. Swapping just a rad valve is not too bad as you resuse
the olive and nut.

Yup it was cool. Needed to put a new service valve in place to allow a
new tee'd section to be added in before the existing rad.

What's the difference between a service valve and an isolation valve?

Pretty mUcH nothing. Most of it's just what you were brought up on.
