What is the default value to specify Dual flush - how many times will it be full flush and how many times will it be low flush? Would appreciate if anyone could let me know at earliest. Thanks, BK _________________ Bharat Architect, LEED AP

I can't say for certain, but I would guess you would assume 3 low flow uses and 2 full flush uses per day for each occupant? Hope this helps, and sorry I can't be more definitive... _________________ Joel McKellar, LEED AP Real Life LEED - A blog devoted to practicing LEED professionals

I will take 2:3 assumption as you said - would be playing a safer game. _________________ Bharat Architect, LEED AP
