I hope not because I really, really love our new dual flush toilet. Hubby installed it today. Looks great doesn't it? Next job is installing one downstairs in our tenant's apartment. We made sure to pick a toilet that was on the city of Ottawa's approved list, which means we should get a $75 rebate per toilet.

Hands down one of the biggest things you can do to save water using your toilet is to practice selective flushing - something that folks who are on well water or have a septic system are well aware of. We'll still be doing it even with the dual flush toilet.
