Flushmate is a leading manufacturer of pressure-assisted, water-conserving toilet systems designed for highly efficient and reliable single-flush performance.
Flushmate, a subsidiary of Sloan, is a pioneer in pressure-assist technology for toilets. Unlike traditional gravity-fed toilets, Flushmate systems harness the incoming water supply line pressure to compress air within a specialized internal vessel. This stored pressure delivers a forceful, efficient flush that saves water and maximizes bowl-clearing capability while limiting the need for double-flushes.
Their product lineup includes the widely used 503, 503H, 504, and ultra-high-efficiency 503UH series systems, which are proven to consume significantly less water on average compared to traditional toilets. Utilized heavily in both commercial and residential settings around the world, Flushmate's innovative solutions also feature modern upgrades such as complete replacement kits and the I-Flush touchless sensor system for hygienic, hands-free operation.

Common questions about manuals, registration, and support for this brand.
No, gravity-fed toilets cannot be retrofitted with a Flushmate System. Flushmate systems require specially designed pressure-assist toilet bowls to accommodate the powerful flushing action.
Check the actuator adjustment to ensure proper clearance. Additionally, clean the shank inlet screen, verify that your water supply pressure meets the minimum requirements, and cleanly reinstall or replace the flush valve cartridge if needed.
Standard models like the 503 and 503H series require a minimum water pressure of 20 psi. The 503UH and 504 series require at least 25 psi. The maximum operating pressure for all units is 80 psi.
Turn off the water supply valve and flush the toilet to relieve pressure. Place a bucket under the lower supply shank, disconnect the water line, and let it drain. Push down on the actuator and pull it up momentarily to let air into the vessel. Do not pour antifreeze or other chemicals into the china holding tank or the Flushmate tank.
