Adding a basin to a toilet with no route for basin waste pipe

Jul 19, 2004 22 Replies

Actually some folks have gone thru the calculations and hes right this time, its an excellant idea. Its a simple cross flow heat exchanger: warm waste preheats the cold supply so less hot is needed. Cuts hot use quite a bit.

ISTR paybacks of about 6 months. I posted on a thread about it somewhere, not sure which ng though.

maybe, maybe not... prestige and image is big for most buyers.

You've got 2 fills, the mains with ballcock as usual, plus sink waste. So it fills even if you never wash your paws.

With mains fill at full speed, there is grey water use for a minute or so after flush. If you want to capture 100% of grey for longer you can slow the mains fill, if you wish. Very simple, works. No tank, or all the costs associated with it.

Right all the time.
