The advice looks unanimous. Thanks guys for your help. I'll ensure I
have a plug fitted to it when he does the pluming.

Incidentally what will happen to the pump if i test it without any
water flowing through it (i.e. just air). I've heard this can be
terminal - but is the effect immediate - or does it need to happen for
a few minutes before it dies out on you ?

BTW - I won't be trying this - I was just curious.
