The main cold water stopcock in my house is old and stiff and weeps for
a while after it has been turned on or off. Are there any disadvantages
to inserting a new quarter turn ball valve above the existing stopcock?
There is also a drain cock above the existing stopcock which I would
move above the ball valve.
I presume the drain cock is there to let out the water in the pipes
above the stopcock and it would be a goo idea to do this before I cut
out a section of pipe for the new ball valve?
I thought that as well, but I can't find anything obvious in the street.
I will have a word with the neighbours to see if they know where it
So there is no problem having the quarter turn ball valve as the main
Ours is out the back, near our side gate (inside the gate). Just a
No...I had one fitted by the water company since it was going to be a
sod of a job, and the main stopcock serves another property too so I was
anxious to minimise 'off time'. It's fine, and dead easy to operate!

Can't see any reason for not having a quarter turn ball valve. Presumably it
is full bore, and not restricted when open?
With regard to the weeping with the existing stop tap - I presume that this
is round the spindle? Have you tried tightening the gland nut, or re-packing
the gland with hemp or similar?
Absolutely. I was in exactly your position, but the old stopcock would only
turn off a little. It went from gushing to flowing steadily at the kitchen
tap. We cut the pipework above the old stopcock and jammed a new section of
pipe with a quarter turn valve on it. The amount of water that came out was
surprisingly little, really, when you work quickly. Then we opened up the
original stopcock and whacked in loads of gland packing.
I'd always use a full bore quarter turn lever ball valve. Every other type
of valve is crap. How the Europeans must laugh at our sticky leaky gate
P.S. Buy a decent branded valve for this application. I went for Pegler.
It's not somewhere to make compromises.
