NC-2009 WEp1: Water Use Reduction—20% Reduction
Hi,
Can anyone please advise on the following;
Do shower flow rates need to be calculated at 80 psi and installed at 80 psi?
The same for for faucets, do flow rates need to be calculated at 60 psi and then installed at 60 psi?
Thank you.

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?

Hi Francis,
The psi (based on 60 psi for lavs and 80 psi for showers) is how the industry/manufacturers calculate the GPM flow rate for their fixtures. The calculations must be performed using GPM rates based on these pressures, but there is no pressure requirement for installation.
