The Sloan Flushmate Cartridge C-100500-K is designed to replace the flush valve cartridges for 1.6 and 1.0 gpf Flushmate models including Series 501A, 501B, 503, and 504.

The Flushmate flush valve cartridge assembly is located in the center of the Flushmate system and accessed from the top of the Flushmate system. This is one of the few moving parts and needs to be maintained for optimum performance. The cartridge assembly is the main valve that opens and closes to deliver the water to the toilet bowl.

The Flushmate C-100500-KIT is specially designed to replace your existing Flushmate flush valve Cartrdges for both 1.6GPF and 1.0 GPF Flushmate Series system.

Why would you need to replace the Flushmate cartridge?

  • Some Common Reasons Include:
  • Sluggish Flush: A slugging Flush occurs when the flush seems weaker than before or when all the waste is not removed from the bowl.
  • Water draining from around the toilet rim: You may notice continuous water running into the bowl between flushes. This will appear as a minor amount of water to drain from around the rim of the toilet.
  • Water in Cartridge Area: Water in the cartridge area may indicate a minor hole in the diaphragm of the cartridge will cause water to fill in the cartridge area.
  • Flushmate system not setting up: If the Flushmate system will not setup and keeps running. This can be caused by the cartridge not closing properly and may need to be replaced.

  • How do you install the Flushmate Cartridge?

    Flushmate has made the cartridge replacement process simple. The cartridge on all Flushmate systems can be removed by turning the cartridge counter clockwise. Installation is simply screwing the cartridge into the Flushmate system clockwise. The replacement process normally only takes 15 minutes.

    1. Turn off the water and flush the toilet.
    2. Hold the actuator down until the vessel is completely drained.
    3. Actuator rod removal is a simple procedure using a screwdriver. Disconnect the rod from the handle assembly. Next only need to loosen the two screws toward the front of the tank holding the actuator rod in place. Remove the screw located closes to the cartridge and front of the tank. Be very careful not to drop the screw into the tank when removing or installing. This will allow the clip to be moved out of the way. Lift and slide the actuator rod out toward the front of the tank.
    4. Remove the cartridge assembly by inserting the pliers handle into the spooks of the cartridge or with our FLUSHMATE 2-in-1 wrench. Remove the cartridge assembly by turning in a counter-clockwise direction.
    5. Remove the cartridge.
    6. Before you install the new Flushmate cartridge, first turn the water supply back on and allow the water to flow for about 30 seconds. If there is any debris that has been trapped inside the FLUSHMATE unit, this should clear it away. Look inside the FLUSHMATE unit to make sure there is no debris inside the sealed surface. Debris or defects in the sealed surface can cause the unit to continue to run on.
    7. Then, reinstall the cartridge by turning the cartridge assembly counter-clockwise while pushing down and applying some pressure to avoid cross-threading. Stop when you hear an audible click, caused by the threads engaging.
    8. Next, turn clockwise to install the cartridge back into position until a thread or two of the FLUSHMATE unit are showing above the cartridge.
    9. Then, turn the water back on and keep slowly turning the cartridge in 1/4 clockwise turn incrementss, waiting 15 seconds between turns until the water stops running into the toilet bowl. Once the water stops, no additional adjustments to the cartridge installation should be required.
    10. Install the flush rod if it was removed and make sure there is no interference in the proper adjustments to actuator is made. The actuator may also need to be adjusted if you have a push button model. In either case, the proper clearance between the flush rod or push button to the actuator is important to ensure proper flushing actuation.

Easy to install with concise instructions! USPS took a week to deliver the kit and never received an email with tracking number. However USPS informed delivery allowed me to track the package. Toilet is working like new!

This was really easy to install! Don’t be intimidated by the mechanism! And women, yes, you can do this too! Just look up Flushmate’s tutorial on YouTube and you should be able to do this all by yourself! The cartridge was put it extremely tight by the person who worked on this last so it took some extra elbow grease to remove but after that it was easy-peasy! Save yourself hundreds of $$ and learn a new skill! Give it a shot ;)
