Could anyone tell me the diameter of bath wastes in Australia and in the USA.I have produced a patented device which fits UK baths wastes (70% plus on most baths) enabling the water to be siphoned out of the bath and re-used.I wondered whether the sizes abroad were in common with the UK sizes.Indeed are there any wastes which are the same as the UK?
I understand that there are problems associated with the legality of recycling of grey water in the states does anyone know which states allow and which do not (bath water only).
Any help would be very much appreciated.
Kind Regards
Martin
