  • Water savings for life

    The flush volume will not decrease, which means the water savings are sustained for the life of the fixture based upon EPA standards of 25 years.

  • 20% less water*

    Flushmate models can consume up to 20% (1.28 gpf) and 38% (1 gpf) less water than 1.6 gpf gravity toilets on average.

  • Fewer double flushes**

    70 gallon per minute peak flow of Flushmate pressure-assisted technology is designed to clear the bowl on the first flush.

*Based on internal testing completed in 2021

**Flushmate uses ANSI Standards for bowl clearing and drain line carry with miso testing

Superior flushing performance.

Pressure assisted toilets with the enhanced Flushmate 503 Series models produce up to 25% increase in waste extraction, based on internal testing of previous models.

MaP scores represent the number of grams of solid waste (soybean paste and toilet paper) that a particular toilet can flush and remove completely from the fixture in a single flush.

How it works.

The Flushmate system traps air as it fills with water, uses the water supply line pressure to compress the trapped air, forces water into the bowl, and effectively pushes waste out.

  1. Water flows into the vessel
  2. Vessel ready to flush
  3. Air pressure empties the valve

Superior drain carry*

Flushmate equipped toilets use pressure (versus gravity) to produce a longer drain carry, pushing waste up to 50% further than the recommendations set by the American National Standards Institute (ANSI).

Test conducted according to ANSI standard procedures as discussed in APSE Research Report 91-01.

*Based on ANSI Standard of 40 feet with Sloan’s testing results at 60 feet on average

Drain Carry

All systems go.

There's a Flushmate system to meet even the most demanding flushing needs without limiting toilet options.
