    For £20 he couldn't have drained and re-filled.
    If you're fast you can do it without draining down, and cap them off.
    If you miss, or it goes wrong it's messy though. Plug the tank in the loft if you do it this way, but for a loft coversion the water will have a long way to go if it goes bad on you.

    This is a very common way to work live on pipes that don't need soldering.

    You have to bung the cold fill, but also cap the open vent.

    I have had many a strange look from customers when I have asked if they have a spare carrot!

    If a combi or system boiler, then just release the pressure down to zero and the vacuum will soon form to stop water running out.

    You could of course always freeze the pipes, but then this involves extra cost.

    You cut the pipe, and have a small trickle of water, which stops.
    Then from somewhere above you hear a gurgle in the pipes................
    How fast can you get a compression stop end on?

    I'm not criticizing him, just advising if you do it yourself, drain the system down, then re-fill with inhibitor included.
    I do know plumbers who chop the pipes, get there thumb on, then get a stop end on, without draining down though. (Me, for one, but maybe not in a loft)

    No i know you weren't! Ah i see in that case he did drain it as remember him sitting there waiting for it to ..well drain!
