Water-efficient bathroom fittings being reviewed against a water-use calculation

Overview

A Part G water-efficiency calculation uses the proposed sanitary fittings, appliances and flow rates to assess calculated daily water use. If an initial specification does not achieve the applicable requirement, individual fittings can be reviewed rather than changed indiscriminately.
