ASSE 1016 Performance Requirements for Automatic Compensating Valves for Individual Shower and Tub / Shower Combinations ASME 112.18 / CSA B125.1-05, Plumbing Supply Fittings
Any shower with more than one showerhead or hand-held unit that has the possibility of rinsing the same person at the same time automatically disqualifies the home from meeting this measure. A large shower stall with multiple showerheads will qualify if the showerheads cannot be used by a single person at the same time and if all showerheads meet the flow rate requirements.
G2.2. WaterSense Bathroom Faucets( 1 Point) Residential lavatory faucets should have a flow rate ≤ 1.5 gallons / minute. Non-residential metered faucets should have a flow rate ≤. 25 gallons / minute. The flow rate mechanism may be factory installed or an accessory. G2.3. WaterSense Toilets with a MaP Threshold of No Less Than 500 Grams( 1 Point)
All toilets must comply with this measure to earn credit. Retrofit or after-market kits to convert a standard toilet to a dual flush toilet are prohibited. Toilets must qualify as high efficiency, with 1.29 gallons per flush or less with a MaP score of 500 grams or greater.
G2.4. Urinals with an Average Flush Rate of ≤ 0.1 Gallons / Flush( 1 Point) Note: This measure applies to multifamily projects only.
All urinals must have an average flush rate of ≤ 0.1 gallons per flush. No-water urinals comply with this measure. To calculate the average flush rate, add up all of the urinals installed in the building at the time of project completion( including non-residential tenants). Add up the flow rates of each urinal, and divide that total by the number of units.
Note that code issues may arise for projects considering the use of waterless urinals; check with the city building department for more information.
Note: This measure applies to multifamily projects only.
VERIFICATION Measure G2.1
Field Verification: The Rater will complete field verification to confirm that the installed product meets specifications.

Measures G2.2 and G2.3
DRAFT
Field Verification: The Rater must complete field compliance verification and take representative photos of fixtures.
Documentation: The Rater must collect documentation that shows the flow or flush rate of installed fixtures, and a MaP score for toilets. If the flow rate is noted on the fixture, the Rater may complete field
