MaP completes first HET field audit

2011 saw the completion of MaP’s first field audit of MaP-tested WaterSense toilet fixtures. MaP purchased nine different toilet models (from nine different manufacturers) at retail and re-tested them to assess their continuing compliance with the rigorous requirements of WaterSense. All 9 were found to be fully compliant. Eight models retained their original MaP score, while one experienced a decline in that score, which has been reported to the manufacturer. For a full description of the audit process, go HERE.
