Hi all,

How would you set the water use for urinals that:

1. Have a 2 liter pre-wash that may be used or turned off
2. Have fuzzy control for the flush (2 to 4 liters)

The worst case is 6 liters, but the actual water usage depends on building operation and the fuzzy control. Do you think it is fair to exclude the pre-wash and pick up the middle value for the fuzzy controlled flush (3 liters)?

Thanks in advance,
