Flushmate models can consume 20% to 38% less water than 1.6 gpf gravity toilets on average.
Fewer double flushes
70 gallon per minute peak flow of Flushmate pressure-assisted technology clears the bowl on the first flush.
Water savings for life
The flush volume will never decrease, which means water savings are sustained for the life of the fixture.

New and Improved 503 Series
Engineered for lasting performance
We've designed our NEW 503 and 503H Series models with an enhanced vessel structure and increased flushing performance. Our enhanced design maintains the current size to making upgrading your existing Flushmate 503 and 503H system easy.
Pressure-assisted toilets with the New Flushmate 503 and 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.
Water flows into the vessel

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

Flushmate lives inside your favorite brands.
Flushmate vessels are installed in pressure-assisted toilets from your favorite leading brands.
A 50% larger water surface area in Flushmate-equipped toilets reduces odors and keeps the bowl cleaner by reducing the dry surface area.
Non-Sweating Tank
Water is contained in the Flushmate system. The result is a non-sweating toilet - so the floor around the toilet remains dry.
Advanced Bowl & Trapway Design
Flushmate®-equipped bowls are hydraulically designed to harness the powerful flush which "push" contents out of the trapway instead of gravity siphoning. Flushmate’s trapway is simple, only needing one bend, eliminating the need to double flush.
Traditional Installation
Installs in the same standard dimensional area as a standard toilet. Flushmate-equipped toilets are available in 10”, 12”, or 14” rough-in.
