does anyone else prefer to drain down than chance the gate valve.

I do, its a lot easyer than changing when the pipe is full 😉🙂😀

 

[WOLDEN]

drain down is better ,as gate vavles tend to seize , but perfer using bung,s , in quick repairs .

 

[Robtheplumb]

sorry but you did leave yourself open to that!

Much more exciting changing when pipe is full.

 

[Robtheplumb]

Drain down and replace the gate valves usually, poxy things!

Its okay draining down sometimes.

But get a job on a cylinder cold feed and you can trap an awful lot of air in it if you drain down.

At least if you open a gate valve with a full tank of water, the surge of water usually drives the air out.
