changing float valve in cold water tank - and pipe freezing!

[Agile]

A little professional tip.

When doing a job like that turn on all the mains taps kitchen and outdoors fully so that if the freezer fails or if the street stopcock does not turn it off completely then there is less pressure to stop anyway.

Some experienced plumbers would just do that and cut the pipe and "snatch" on an isolating valve if the mains flow is not very good anyway. Spills 2-3 litres of water and takes 2 minutes rather that fiddling about with external stopcocks full of mud or even risking breaking an internal stopcock.

Oh I think there's a bit of false Modesty going on here John... That one isn't nearly as big as yours!

will this Universal stopcock key as shown above fit most external stopcock heads?

In theory they do but in practice the work well on the "T" taps, fairly well on the 3/4" square but are not very good on the common 1/2" we find mostly in London.

Possibly if the head is a bit dented they dont slide over?

I would want to carry a dedicated 1/2" tool.

If you aready have a socket set "spanners" which usually includes a T-handle and extension bars, there might be a socket that would fit the shaft.
