MaP Testing

Some products are high-performance.

Some are high-efficiency. And some are BOTH!

Admit it….no one wants to sacrifice performance to achieve a high level of efficiency!

Fortunately, with the launch of MaP PREMIUM-rated plumbing products, you won’t have to. The MaP PREMIUM label identifies those rare products that offer both superior performance AND superior efficiency!

For example, all MaP PREMIUM-rated toilet fixtures are certified to the rigorous U.S. EPA WaterSense specification.

PREMIUM-rated toilets ALSO:

· Deliver a MaP rating of at least 600 grams – 70% more flush performance than the current WaterSense requirement!

· Flush with no more than 4.0 liters (1.06 gallons) – that’s 17% less water than the current WaterSense requirement!

Simplify your search for high performance, high efficiency plumbing products – look for MaP PREMIUM-rated products.

We researched the MaP scores on 24 of those models. You can download our one-page listing (in alphabetical order) and see how each performed on the MaP test.

To view Consumer Reports ranking order or their specific ratings, you’ll need to either purchase the magazine or visit their website.

MaP Testing helps the Bill & Melinda Gates Foundation

According to the foundation, “About 2.5 billion people use unsafe toilets or defecate in the open.” MaP Testing is now helping with sanitation and enhancing human dignity by providing synthetic feces for testing.

“MaP’s synthetic material helps demonstrate what the equipment can do, without having the real stuff around.”
