Operating Requirements

Water Pressure
Pressure-assist toilets harness the energy of incoming water and air to provide a more robust flush. It is important to have sufficient pressure and flow in the water supply for the Flushmate System to function.
Minimum Operating
Pressure: 20 psi / 137.9 kPa
Maximum Operating
Pressure: 80 psi / 551.6 kPa
Minimum Water Flow Rate: 1 gal. / 3.79 l in 30 seconds

Water Supply
Flushmate Systems are designed to be used with a cold, potable water supply only. Use of non-potable water supply or a hot/tempered water supply may damage the system and will void your Flushmate Limited Warranty.

Toilet Installation
