Dual Flush for All

You may have run across dual-flush toilets in commercial applications (at a large workplace, the airport, the baseball park), but not too many of us have home dual-flush toilets. If you're anything like me, replacing toilets is at the low end of the home-improvement priority list (after replacing leaking windows, replacing the broken air conditioning, etc). If the toilet works, don't trash it!

There are lots of ways to reduce your use of potable water for toilet flushing, including the tried and true brick in the tank method, and the slightly personal "if it's yellow, let it mellow" technique. Well, a new way is coming in 2009: the "Perfect Flush."

This product is a dual-flush retrofit for your existing toilet, manufactured by brondell. They claim it takes less than 30 minutes to install. If their claims are true, and the price is right, this could be a great option for small businesses and homeowners alike.

Funny enough it never occurred to me that we could retrofit existing toilets to add the dual-flush capability. I think this is great and would certainly consider doing each unit in my house!!

this totally rocks - I can't wait to see how this works in early '09.

A regular toilet is not designed to flush paper and solid waste with reduced amounts of water, so the likelihood of clogging or having to flush twice increases. Standard US toilets clear the bowl with siphon technology, so the diameter of the trap way has to be a small as possible (please view siphon vs. washdown technology here If you are serious about saving water, want a toilet that really works and is affordable, I would highly recommend a Caroma Dual Flush toilet. Caroma toilets offer a patented dual flush technology consisting of a 0.8 Gal flush for liquid waste and a 1.6 Gal flush for solids. Caroma, an Australian company set the standard by giving the world its first successful two button dual flush system in the nineteen eighties and has since perfected the technology. Also, with a full 3.5” trap way, these toilets virtually never clog. All of Caroma’s toilets are on the list of WaterSense labeled HET’s and also qualify for several rebate programs currently available throughout the US as well as LEED points. Please go to for more detailed information or visit to see how we flush a potato with the half flush (0.8 gallons), meant for liquid waste.
