There is a very specific comment that eligible toilet fixtures only include tank style fixtures. Yet I see commercial style flush valve fixtures on the EPA WaterSense website.

Hi everybody

We are in the construction phase of a project and the design phase has been already reviewed by USGBC

Is it an absolute requirement that the proposed pressure (in PSI) matches the baseline. Can we use a flow rate at a lower pressure to avoid excessive pump sizes ?

Hi, I am just wondering what would be a European equivalent to Water Sense Labeling for projects outside the US.
