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.




Just make sure you've turned everything "OFF" before you do the job. Then
make sure you turn everything back "ON" and check for leaks when you're
done.
