NC-2009 WEp1: Water Use Reduction—20% Reduction
Hi,
How should be the compliance (of 0.25gpc) for sensor based lavatory faucet be checked if the manufacturer mentions only “ adjustable from 1 - 20 minutes “ , the model in question is EAF-200-P-ISM(by SLOAN)

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?

Mohammed, do you mean 1-20 seconds? The GPC should be base on 12 seconds of flow.

charles, you can refer the product data sheet at :
http://www.sloanvalve.com/Specifications/Optima_Lino_EAF-200.pdf
the data sheet states "Continuous Run — 2 minute default setting (adjustable from 1 - 20 minutes)"----this is all that it states with respect to sensor timing,

Mohammed, The faucet is designed only to operate when the users hands are within range of the sensor beam, and will shut off automatically after 2 minutes of continuous flow. "Water will flow until the hands are removed or until the faucet reaches its automatic timeout setting"
The 1-20 minute run time is part of the of the "iq Click Feature", which is optional. This feature allows the user to change the automatic timeout setting of the faucet to 1 - 20 minutes. The spec does states that this feature is not recommend for public restrooms.
GPC would still be calculated based on flow for 12 seconds.
