Plumbing professionals and contractors are on the forefront of implementing residential and commercial water efficiency plans. With toilet fixtures, it is critical that plumbers make correct recommendations.
The consequences of bad recommendations include call-backs, complaints and non-compensated work. MaP provides the kind of research needed to assure the design professional and contractor that their toilet selection is not just about initial cost, but also about fixture performance.
MaP enables the plumbing professional to make the right choice with accurate documentation. Because MaP participation from the manufacturer is voluntary, not all toilets in the marketplace are listed. To date, 3.561 toilet models from over 100 brands have been tested and listed in the MaP online database. Of these, 2,865 are certified to the U.S. EPA's WaterSense® specification for high-efficiency tank-type toilets.
For the commercial application, MaP tests have been conducted on 556 flushometer combinations, 384 of which are High-Efficiency Toilets (HETs), flushing at 1.28 gallons OR 1.1 gallons per flush. Information on all tested combinations (including WaterSense-compliant valves and bowls) is accessible through our Flushometer database.
A Driving Force in Toilet Efficiency
Over a 10-year period, competitive pressure and MaP testing has resulted in hundreds of high-performance, efficient 21st-century toilet fixture models being introduced into the marketplace, for which manufacturers must be given great credit!
For example, in 2003, the average North American toilet MaP test score was 350 grams (about 12 ounces of solid waste). By 2012, the average MaP test score more than doubled to nearly 800 grams (over 28 ounces)!
