Has anyone explored the discrepancy that has been created by the new WaterSense requirements for flush fixtures at 1.28 gpf minimum? We're now getting cut sheets for projects that have 1.6/1.1 gpf dual flush toilets on a project that no longer have a WaterSense label and are wondering if we need to find a substitute. I've had comments in the past about cutsheets not showing the label, so wondering what LEED reviewers will be looking for...the label or the flow compliance?

Hi Bethany,
I asked a LEED Coach about this. Whether we needed to have WaterSense flushometers for non tank style toilets since they are now "eligible" per the website. She said no. You might try a query yourself just so you have something in writing.

I received the same response for LEED v4 from LEED Coach pasted below. NOTE: LEED v4.1 does include WaterSense label for commercial toilet tanks and flushometer valves.
Thank you for contacting GBCI regarding WEp Indoor Water Use Reduction. For LEED v4 projects, it's correct that a WaterSense label is only required for fixtures that were eligible for the label when LEED v4 was published: residential (tank-type) toilets, water-using urinals, private lavatory faucets, showerheads. For urinals, both tank and flush value must be labeled.
For the LEED v4.1 prerequisite, commercial toilet tanks and flushometer valves are additionally required to be WaterSense labeled. Further, any additional fixture types that are eligible for labeling when LEED v4.1 is finalized will also be required to have a WaterSense label for the v4.1 prerequisite
