LEED V4 prerequisite for prerinse spray valves is 1,3 gpm (4,9 liters per minute) but I haven't found any products with such low flow rate sold in Finland. Some manufacturers have products with 6 liters per minute which was required in V3. Has anyone experienced, what products have been used in Europe or is there possibly ACP for projects outside the US? In reference guide it is said that in countries where WaterSense in not available project must comply with the 20%-below-baseline requirement but have no additional performance requirements. However, the requirement for prerinse spary valve is not WaterSense label but the flow rate, so I guess prerinse spray valve cannot be excluded?
