  • Water savings for life

    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

    53% less water*

    Flushmate models can consume from 20% (1.28 gpf) and 53% (0.75gpf) less water than 1.6 gpf gravity toilets on average.

  • Fewer double flushes

    Fewer double flushes**

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

We've designed our 503, 503H, and 503UH Series models with an enhanced vessel structure and increased flushing performance compared to previous Flushmate 503 models. Our enhanced design maintains the current size to making upgrading your existing Flushmate 503, 503H, and 503UH system easy.

MISO Testing results for Flushmate 503

Superior flushing performance.

Pressure-assisted toilets with the Flushmate 503 and Flushmate 503H Series models produce up to 25% increase in waste extraction.

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 Society of Mechanical Engineers (ASME).

Test conducted according to ASME A112.19.2-2018/ CSA B45.1-18, Drain line transport characterization test.

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

All systems go.

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