Gate Valves

[Trevor Smith]

Yesterday my Showerforce self contained shower started leaking on the
control spindle so I went to turn of the two gate valves and neither the hot
or cold would turn of the water fully, now this is tank pressure water and
they couldn't stop that. I am now thinking of removing them and replacing
with isolating valves but the ones I have seen seem to go down to about 10mm
through the ball and as they will be on low pressure water I think they
would restrict the flow to much. Is there a 15mm isolating valve that is
15mm all the way through?.

Thanks for that Bruce, they look better than the ones that require a
screwdriver.

That sounds about par for the course for a gate valve... useless sodding
things!


Yup, get some "full bore" leaver ball valves. Much nicer all round (apart
from price)

I didn't think that

was a bad price,

Or remove them, clean out what is blocking the valve closing fully
and get into the habit of working the valves every six months or so.
Fully closed, fully open and then close 1/4 of a turn. I have yet to
have one that has been worked in this way fail.

If you are having to remove them to clean, surely it would be better to
replace it with a more reliable device that needs less maintanance though!
