Did you know that if you are not careful, converting a single flush system to a dual flush system could actually waste more water? Using our optimal installation guide, we show you how to measure your water so that you can save the most water. We spent a lot of time on the adjustment because if each person flushes 6 times daily, that is 2000 flushes a year per person.
The installation instructions from the manufacturer aren’t the best. First, it didn’t discuss how to adjust the blue clamp on the refill valve. Second, adjustment for the half flush from this manufacturer may require you to waste too much water before finding the right point on the dial. We provide the optimal Golden Section solution to waste a minimal amount of water while testing.
If you decide to purchase the real dual flush kit, here are couple of links for the products:
for Fluidmaster DUOFLUSH Fluidmaster DUOFLUSH
for Danco Dual Flush: Dual Flush by Danco at Amazon
People who are accustomed to the single flush system may accidentally push the lever down when they intended to half flush. Since liquid waste is more frequent than solid waste, pushing down the lever by mistake would cause more water waste. In this video we provide one simple solution to swap the half dial and the full dial.
