FAQs about WEp2 :

How does the CEE Tier 3A criteria for commercial clothes washers compare to ENERGY STAR certified washers?

Is the WaterSense label really required, even if a non-labeled fixture has a comparable flush or flow rate?

Not all fixture types can get the WaterSense label. Which fixtures do we need to ensure have the WaterSense label for our project?

How can I check the conformity of a technical data sheet for a shower head?

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?

Hi Sara, What I know is that plumbing design is done on the basis of maintaining 1.5/2 bar pressure at the faucet terminal. So, you can select flow based on your design pressure requirements.
