One2flush Installation
In A 1.6gal/flush Low-Flow Kohler
This single-flush toilet is 14 years old and now has a new life. It is now as efficient as most of the new H.E.T.’s (high efficiency toilet) and way more efficient that a lot of the cheaper ones that don’t have any adjustments to fine tune the 1/2 and full flush flush volumes. This toilet easily converts to dual-flush and now uses only 1 gallon on the 1/2 flush! That’s a 37.5% savings with every half flush.

Step-By-Step Detailed Installation Video
In this detailed installation video, the One2flush is installed in an American Standard (5 gallon per flush!) toilet that was installed in this home back in 1973. You’ll see the steps in detail as we convert this toilet to dual-flush. Now, in the half flush mode, this toilet only uses 2 gallons which seems like a lot, but remember, this toilet was wasting 5 gallons per flush. This toilet in the half flush mode is now saving 3 gallons per flush, a 60% savings! Every toilet is a little bit different, so your savings may vary.
