Wello's Water Wheel


 

In developing countries, women spend over 25% of their time collecting water -- but the Water Wheel from Wello helps women transport up to 5 times more water as compared to traditional methods!

Public Restroom Hygiene


The Bradley Corporation recently did a survey on public restroom hygiene and reported that people Don't Want to Touch Things in The Bathroom!

Rinse or wash? Over 2/3 of the respondents admit to rinsing only. Click here to learn more and understand how you compare!

Not MaP Tested = NM


Until recently, as a courtesy to consumers, water utilities, and toilet manufacturers, the MaP listings included all WaterSense®-certified toilet models even if these models had not been fully MaP tested.  At one time we identified the MaP Flush Score of these models as “NM” for “Not Measured”; at other times we listed them as ">=350” to indicate that they would flush at least 350g

However, we have received feedback indicating that this designation may be somewhat confusing to consumers and others.  As such, we have decided to move the listings for WaterSense®-qualified toilet fixtures that have not been fully MaP tested to a separate list.  We trust that this action will eliminate any confusion regarding MaP scores. 

Therefore, effective in October 2014, our MaP lists for toilet and urinal fixtures will be separated into these categories:

  1. Primary list of fully MaP-tested tank-type toilets, including MaP-tested WaterSense®-qualified fixtures.  This list will be attribute-searchable and downloadable as both PDF and Excel documents.
  2. Secondary list of all WaterSense®-qualified tank-type toilets that have not yet been fully MaP-tested (downloadable as a PDF document).  No MaP score will be provided.  Toilet physical attributes, where available, will be provided.
  3. List of all MaP-tested flushometer valve and bowl combinations for both standard and high-efficiency toilets (downloadable as PDF and Excel documents).
  4. List of all child- and junior-sized toilets of both tank-type and flushometer design (downloadable as a PDF document)
  5. List of MaP PREMIUM-rated tank-type toilets (WaterSense-qualified, 1.06 gallons per flush (4.0 litres per flush), and 600 gram minimum MaP score), downloadable as a PDF document.
  6. List of all High-Efficiency Urinals (HEUs), including all WaterSense®-qualified flushing urinals and all non-water urinals, downloadable as a PDF document.

MaP Testing Protocols


Unlike some other testing organizations, MaP Testing protocols and processes are entirely transparent.  Our Version 5 test protocol is not "secret" nor does it use test materials (test media) that have no relationship to the "real" demands upon a toilet fixture.  MaP tests use soybean paste and toilet paper as a close replicate of the "real world."

California's 600g & Water Savings


Recently, the major energy utilities in California (PG&E, Southern California Edison, Southern California Gas, and San Diego Gas and Electric) proposed to the California Energy Commission that the State mandate a minimum MaP flush performance score of 600 grams (21 ounces) on all toilets sold in California.  In our opinion, this is a flawed effort to achieve a higher level of water savings.  While we laud the intent, we cannot support the proposal because it is based neither on science nor real-world evidence.  Increasing the flushing “power” of a toilet simply does not result in additional water savings.

Ontario Canada Province moves to High Efficiency Toilets


Ontario, Canada continues to be a water efficiency leader in Canada.  As of January 1, 2014, the Ontario Building Code (OBC) reduced the maximum flush volume for toilets installed in new residential buildings from 6.0 litres (1.6 gallons) to just 4.8 litres (1.28 gallons) - a flush volume that is in line with WaterSense values.

Given the significant improvements in toilet flushing performance technology over the last few years, most new HETs will easily out-flush almost any toilet fixture installed before about 2005.

 

THE WAY WE SEE . . . Hot Water on Demand


From time to time, we offer up some thoughts on our own experiences with products and technologies not covered by MaP Testing.  Today, we want to suggest for those of you frustrated by waiting for hot water at the bathroom sink, a simple device that eliminates nearly all of the water waste while waiting.  Both of us have installed on-demand hot water circulation systems.  The systems we installed are user-activated. So now, at the flip of a switch, hot water is almost instantly available at our taps and showers.  Unlike timer-based systems, user-activated systems save energy by never operating when there is no call for hot water. What’s more, the pump only operates until the hot water arrives at the furthest fixture - the energy cost for the pump is less than $2 per year.  We are both very pleased with the water savings and convenience of this product.
