I need to drain down a hot water system soon to fit a new sink (no stop
cocks at all on the hot water side).
To save time, would buying one of the £9ish pipe freezing sprays work
for the 5 - 10 minutes that the 15mm pipe is likely to be open while an
isolator is fitted?
If so, then it could save me a hour waiting for the drain down.
Thanks
Alan.

Get a Drayton Drain Easy Kit £10 - two rubber plugs. Put a plug into the
hot outlet of the cold tank - no need to drain system.

Also allows CH rad valves to be changed without draining!
