I'm glad to see the old toilet gone. It was a first-generation low flow model that never really handled solid wastes well. When the bathroom designer showed us his plan, it included a new dual flush toilet. That surprised me; I've become accustomed to seeing the green-handled flushers in public restrooms, but didn't know they were used in homes. After thinking about it for a while, Hubby Tony and I agreed it would be a good idea.
In a dual flush system, the low volume flush cycle provides enough water to handle liquid waste, and the additional water in a complete flush helps to remove solid waste. Our new toilet has a lever with two handles on the left side of the tank. The longer paddle is green, and you push it for the low volume flush. If you push the full lever you get a complete flush.
We've only been using this new system since Friday, but I think I'm really going to like it!
