Jeez Lads,
Plumbers ! who needs 'em. You lot are fantastic. It was just a despairing query ... and...... look at the results. including some great homespun wisdom..
Many thanks fellows (and gals?)
Yes the hot system to the bath seems pretty normal with a 3/4" pipe serving the tap. The adaptor mentioned is screwed on to the tail of the tap, reducing it from 3/4" to fit the 1/2" pipe, which is T- eed off from cold water main feed (1/2" also) to the W/H basin and thence to the kitchen sink. OK? . Just so long as the pressure is not too slow I suppose, and it does seem to be more than adequate. Mind you I would'nt be able to change to a mixer tap with such a system.
Cheers and thanks again.
