Hi everyone! On our project, we have installed wc flushing valves that can be manually adjusted to gain higher water use reduction. This is specified in manufacturer's catalogue. This adjustment would be applyied by installer and/or building facilities manager. We wanted to know if we can declare this reduction in calculator. Maybe it would be convinient to attach a commitment letter from installer/manager to garantee how these valves would be adjusted and how much water flow they would have during operations. Is this a possible path?
