metered faucets

Right, you can install them but not claim savings from them.

Greetings:  I need to clarify the conversation above; Can manually installed aerators be claimed in WE credits?  

Yes, flow rate savings from aerators are fine. The savings you are no longer allowed to claim are from metered faucets reducing the flow duration in seconds. 

Can you please confirm that I am reading the LEED Reference Guide correctly - public lavs are NOT required to be WaterSense fixtures, just private lavs?

Sara, correct. The language in the Guide under Step-by-Step Guidance confirms: Select WaterSense-labeled products for all newly installed fixtures that are eligible for labeling by
verifying that the manufacturer and model are listed on the WaterSense website. The WaterSense label
can be found for fixtures in the following product categories:
·· Tank-type toilet (water closet)
·· Water-using urinals
·· Private lavatory faucets
·· Showerheads

The following fixture types are not labeled by WaterSense and must comply with the percentage
reduction criteria:
·· Tankless toilets
·· Composting toilets and waterless toilets
·· Waterless urinals
·· Public lavatory faucets

Using aerators is an acceptable water savings strategy.
·· Newly installed aerators or flow restrictors added to private lavatories or showers must be WaterSense labeled.
·· For private lavatories, WaterSense requires a maximum flow rate of 1.5 gallons per minute at 60
pounds per square inch and a minimum flow rate of 0.8 gallons per minute at 20 pounds per square
inch. The installed fixtures in the design case must use the rated flow rate from the manufacturer, and
the underlying assumptions must remain consistent between the baseline and design cases. (I threw in the aerator language for reference to the previous question)  

Hi All, I know it has been a while since you've talked through this topic, but it's first time we use the metered faucet in v4. Do I get it right that in the newest v4 calculator, if my battery is 4 lpm I have to still put the same value, that is 4 and I cannot put 2lpm (because the assumed default duration is 30 sec so 1/2 out of 4 lpm)? 
Or can we use the column for the non-Default sec and for the Design Flow Rate put a rate just for 10 or 12 sec ?

Hello Everyone,  We receive a data sheet from a manufacturer of a shower head but we do not know how to know if the flow rate meets the prerequisite,LEED or not, because the manufacturer did not clearly write the flow rate but they provided a curve of flow rate according to pressure (He gave the flow rates that correspond to pressures between 1 bar and 3 bars), while LEED specifies the flow rates that correspond to the pressure of 415 KPA / 4.15 Bar. What can I do knowing that the manufacturer does not give any flow value for 4.15 Bar ?
