We are got a comment on a residential project where we installed flow restrictors to reduce the faucet flow rate to 0.5 gpm. The 1.5 gpm flow restrictor is WS labelled but the installed 0.5 gpm flow restrictor is not. If WS labels pertain to water efficiency, wouldn't a lower flow restrictor of the same make and model fixture be WS labelled by association?
Has anyone run into this problem of more aggressive flow restrictors not being WS labelled, while the higher flow of the same flow restrictor IS WaterSense labelled?

We are having the exact same issue with a Commercial NC project. I would like to know if we would still meet the prerequisite if we go with the flow restrictor. Please advise.

WaterSense labeled products meet EPA's specifications for water efficiency and performance, and are backed by independent, third-party certification.
LEED requires that all newly installed toilets, urinals, private lavatory faucets, and showerheads that are eligible for labeling must be WaterSense labeled (or a local equivalent for projects outside the U.S.).
An unlabeled flow restrictor will probably not be allowed to demonstrate compliance with indoor water use reduction savings.
In simple terms...LEED does not believe flush/flow rates listed on manufacturer's submittals are correct unless they are third party verified (e.g. WaterSense). "Trust but Verify" logic.
Hope this helps!

Hello,
Could you told me if it is forbidden by the LEED standard to put an infrared tap in the toilet?
Thanks;
