How to Adjust the Pressure on a Sloan Flushmate

The Sloan Flushmate increases the efficiency of compatible low-flow toilets. The unit uses a combination of water and air pressure to flush waste more forcefully down the drain. If your Flushmate-equipped toilet isn't performing as well as it used to, a bit of troubleshooting is in order. Although it's possible that a part has failed and needs replacement, these relatively simple devices are fairly durable. A minor adjustment might make all the difference.

Modern toilets use less water more efficiently.

Step 1

Locate the toilet water supply valve, typically near the base of the toilet. Open the valve fully and flush the toilet to check for a proper flush. If no improvement is observed, close the valve and flush the toilet again to relieve pressure on the unit.

Step 2

Remove the lid from the toilet tank and set it aside in a safe place. Pour a small amount of water onto the top of the flush cartridge, using a glass or cup. Turn on the water supply. Watch for a stream of bubbles from the cartridge indicating it requires replacement. No bubbles indicates a good cartridge.

Step 3

Place a nickel on top of the actuator button. Ensure that the coin will just slip beneath the flush rod, indicating the proper rod-to-actuator clearance of 1/8-inch. Obtain the proper clearance by loosening the actuator setscrew with a screwdriver, and adjusting the actuator up or down using the long handles of a pair of pliers. Tighten the setscrew and recheck the clearance.

Step 4

Flush the toilet to check for correct operation.
