Hello,

I have a project which has specified 1.6/1.1 gpf tankless toilets.  Since the origionaly published BD+C v4 guidebook stats that tankless toilets are not elegable for watersense labeling in the step-by-step guidance section we did not specifiy this requiremnt during the origional design of the project.  We now know that tankless toilets are elegable for watersense labeling.  We are wondering if the origional LEED registration date of our project preceeds tankless toilet water sense eledgability.  What is the date that LEED began requiring watersense labeling for tankless toilets?
