NC-2009 WEc3: Water Use Reduction
I have some slight doubts about the way commercial prerinse spray valve should be integrated in the calculation. Those are quoted in the credit language, but then, there is no information anymore: no calculation example, no quotation in the Reference guide, and no reference in the template. Does it mean that as long as the prerinse valve flow is under 1,6gpm, it's ok, and that the actual consumption is not taken into account in the calculation?
Thanks

Can you explain the 12-second duration for metering faucets?
Can I use a nonpotable water source to contribute to WEp1 compliance?
We are having trouble finding EPAct-compliant fixtures. Is that a problem?
Where can I find a clear meaning of "public" and "private" as relevant to lavatory faucets?
Are shower duration controls an acceptable water-saving strategy?
Can I include process water savings in order to earn an Exemplary Performance point?

Valentin,
This is a new edition to the WEp1 v4 of the credit. I believe your assumption is correct. As long as the pre-rinse spray value is 1.6 gpm or below it complies with the requirement. The actual consumption does not appear to be taken in to account in the calculation.

That is correct. Prerinse spray valves must in all cases be 1.6 gpm or less. And for projects using the v04 WEp1Prerequisite Form, savings cannot be claimed for prerinse spray valves.
