Product Description


Sloan Flushmate Cartridge Replacement C-100500-KIT for Flushmate 1.6 & 1.0 gpf models

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.

Flushmate cartridge - fast shipping, saved me $$!
Stephanie (NY) | September 1st, 2021
Plumber quoted me $500 to fix the toilet that wouldn't flush! Searched and found the cartridge here - ordered late Tuesday and it arrived Friday. Toilet was fixed in 5 minutes! I would recommend getting the cartridge wrench. I'm so happy to have found eflushmate!

Cartridge Replacement Kit
Tom Van Beveren (C) | September 1st, 2021
I’m so glad I discovered these replacement kits on your website. My toilets both started to run on and on without charging the pressure tank and although I always got them to stop, if I ran out right after flushing, the water could run for hours before I returned! Not good. My plumber friend told me he’d have to replace my toilets; something I wasn’t happy to do. I discovered however my Kohler toilets have your flushmate system is installed from the factory. A search of the internet took me to your website, and the answer to my problem. Your site was easy to navigate and answered my questions. I ordered 2 of your replacement kits and the cartridge socket tool (which I highly recommend over the cheaper choice). Instructions were easy to understand and within 30 minutes I had both toilets flushing like new! I’m very impressed with these cartridges and hope they last as long as the original ones did. Bravo Flushmate!

Clyde of Flushmate told me over the phone he thought I could handle putting this cartridge in - nice to have his confidence - thanks! It came quickly. I watched a video on Flushmate cartridge replacement while comparing with instructions. First time so it took me awhile to adjust everything correctly - but soon it was done - and I was elated!
