Maximum Performance (MaP) Testing & Uniform North American Requirements (UNAR)

Maximum Performance (MaP) Testing &
Uniform North American Requirements (UNAR)

The following 4 sets of specifications and testing protocols were developed by water provider interests. Compliance by manufacturers with each one is voluntary.

1) MaP – MAXIMUM PERFORMANCE testing of toilet fixtures -

2) U.S. Environmental Protection Agency - WaterSense

The U.S. EPA implemented its new WaterSense product labeling and market enhancement program by introducing HETs as the first product to be labeled. The WaterSense specification for HETs incorporates most of the elements of UNAR, including MaP testing to a 350 gram minimum threshold of performance. For information on the overall WaterSense program, go here:

3) UNAR–UNIFORM NORTH AMERICAN REQUIREMENTS for toilet fixtures

What is UNAR….and why was it necessary?
For a number of years, individual water agencies and municipalities in both the U.S. and Canada have been developing toilet specifications and "approved lists" that were sometimes quite arbitrary in their development and were frequently different from one another. It became apparent to both the water conservation specialists AND the plumbing industry that a new direction would benefit everyone - water conservation programs, the plumbing industry and, of course, the consumer looking for the rebate! Thus, the idea was born that a set of common requirements would help to end much of the confusion.

UNAR for toilet fixtures is based partly upon the Los Angeles SPS (see below), and partly upon MaP testing of toilet fixtures ( go to http://www.map-testing.com/ ). It incorporates important criteria focused on sustainable water savings and has been endorsed by water suppliers as well as plumbing industry representatives. UNAR encompasses two tiers of performance: conventional toilet fixtures flushing at 1.3 to 1.6 gallons AND HETs flushing at 1.28 gallons or less.

4) SPS – SUPPLEMENTARY PURCHASE SPECIFICATION for toilet fixtures

Los Angeles Supplementary Purchase Specification (SPS) for Toilet Fixtures (Applies to BOTH ULFTs and HETs)
The SPS applies to toilet purchases under the Los Angeles Department of Water and Power’s Toilet Distribution Program. Compliance with the specification by toilet fixture manufacturers is entirely VOLUNTARY. It was initially adopted as requirement in 2000. As was originally planned, the specification changed its adjustability maximum for ULFTs from 2.4 gallons to 2.0 gallons, effective July 1, 2003. (Note: there are NO PLANS to lower this threshold.) The following documents provide information on this specification:

- SPS - Phasing out the SPS by 2010
- SPS Explanatory Memo
- SPS ULFT Requirements
- SPS-Certified Toilet Fixtures - Gravity and Vacuum
- SPS-Certified Toilet Fixtures - Pressure-Assist
- SPS-Certified Flappers
- SPS Questions and Answers

NOTE: The provisions in the SPS relating to flapper durability and marking of essential repair information inside the tank have been incorporated into the ASME/ANSI A112.19.5 national standard.
