Replacing ball valve in cold water tank

[David]

Hi

I have a cold water tank in the loft, and my overflow pipe drips
outside, I think it is because the ball valve may be long overdue to be

changed. Is this a reason for the overflow to be dripping.

How do I go about such a job? is it really as easy as changing it like
for like ? I dont want to pay £75 for a quick job that I can do
myself. How long is such a job likely to take me ?

Any help would me much appreciated.

Cheers

The most likely reason is a worn washer; that can be easily replaced as long
as there is an isolating valve (there should be) fitted to the incoming
supply.
Even if you have to fit a new valve that is not difficult and with the
proper tools could be done in under 30 minutes.
Check first that the ball is not leaking or waterlogged; gently lift it up
and note if the water stops coming in. A new ball is very easy to fit.

Usually it's just the washer in the valve gone. They cost about 75p to buy
and changing them is fairly simple.

Turn off water, disassemble ballcock replace washer and reassemble.

Even fitting a whole new ballcock is only likely to cost you about £5 if you
do it yourself.
