This is a great water saving idea – so simple and ingenious that you wonder nobody invented it before. When you flush the toilet, fresh water from the clean water pipe comes out of the spigot tap automatically for you to wash your hands. The hand-washing water fills the tank as you wash, ready to be recycled for the next flush. This is a plastic molded fitting that will fit onto a standard tank instead of the lid.
Not only is it a great water saving idea, but it also works well as a space saving feature, when there isn’t room for a full size basin in a small toilet or bathroom. I can see it taking off as a feature in public toilets in eco-friendly resorts too. Perhaps the only possible drawback is the danger of the soap slipping into the toilet itself!
It’s not cheap but it is much more affordable than buying and installing a separate sink. There is also a deluxe version for $20 more that aerates the water as it flows, using even less water.
