I want to tap into the cold water main to take a feed for a new electric
shower. The house has an unvented hot water system (Megaflo type).
Are there any special things to do/be aware of before I shut off the main
stop cock and drain the system/refill afterwards?
Many thanks in advance.
The only reasons I can think of are:
1) S/He wants to add a shower but getting the HW over is really
disruptive? (as opposed to the mains CW and the electric and the switch
2) S/He's afraid the boier will pack in - but Megaflows come delivered
with a (double thermostat) immersion, so just run 15A to it!
