Convert your toilet to pressure assist

This Flushmate system converts a standard gravity toilet to pressure-assisted flushing. It fits left-hand or right-hand porcelain tanks and includes all items needed for the conversion. The unit delivers a 1.6 gpf flush volume. It is designed for residential and light-commercial applications.

Practical limits of the 1-39/64 inch size

The 1-39/64" dimension determines tank compatibility. Tanks with a different internal opening size will not accept this unit. The 1.6 gpf rating sets the water consumption per flush. Installation requires access to the tank interior and a water supply line that meets standard pressure requirements for pressure-assist operation.

Upgrades from gravity flush tanks

This replaces a conventional gravity flush mechanism inside an existing porcelain tank. The jump is worth it when bowl clearance is poor or when a stronger siphon action is needed to move waste through longer drain runs. It is not for tanks that already contain a factory pressure-assist vessel or for one-piece toilets with non-removable tanks.

Questions about this item

Should I pick the 1-39/64" size or a different capacity?

The 1-39/64" dimension matches the plastic body of this M-101526-F31K kit; choose it when your porcelain tank accepts that exact measurement.

What does the 1.6 gpf rating mean once the system is installed?

Each flush will use 1.6 gallons of water, delivering a pressure-assisted discharge that clears the bowl with less volume than a gravity tank.

Does the pressure-assist interface cap flow at 1.6 gpf in practice?

Yes, the internal pressure vessel regulates discharge to 1.6 gallons per flush regardless of supply pressure, so water use stays at that rated figure.
