Water efficiency and conservation. 2,200 toilets flush tested and compared. Learn about Maximum Performance (MaP) Testing!

It takes 635 gallons of water to make one hamburger.* But only a gallon to flush it!

Saving our water

Much is made of the need to conserve water. If we paid more for it, would we be more likely to conserve this valuable resource?

Flush Waste, Not Water

MaP = Maximum Performance

MaP testing for toilets was developed in 2003 because we believe that toilets should flush waste - not water!

This free MaP report provides flushing performance scores for more than 1,600 tank-type toilets and is updated twice monthly. The MaP rating system has been endorsed by consumer groups, manufacturers, retailers, and the US EPA through its WaterSense initiative.

If you want a toilet that performs well, you want a MaP-tested toilet.

About Maximum Performance Testing

Before the development of the MaP Testing Program, many toilets routinely plugged or required double flushing - - they just didn't work!

Because 99 of every 100 flushes will be less than 350g, a MaP-approved toilet fixture must flush at least 350g (12 oz) of sold waste. [ Note: In 2003 half of the fixtures tested could not even flush 250 g of waste! ]

Today, MaP-approved toilets can flush 1,000g of solid waste (over 2 pounds!) -- far more than an human is likely to produce.

NOTE: Manufacturers are NOT required to have their toilet fixtures MaP tested and MaP testing remains a voluntary program. To avoid disappointment, consumers should insist on installing ONLY MaP-tested toilets.
