The flush ball kit is the heart of your Dometic RV toilet's flushing mechanism. This assembly controls water flow from your freshwater tank into the bowl, allowing you to rinse waste effectively. If your toilet isn't flushing properly or the handle feels stuck, a worn or damaged flush ball cartridge is often the culprit—and this genuine OEM replacement restores full function.

Frequently Asked Questions
Q: How do I know if my flush ball cartridge needs replacement?
A: Signs include weak or no water flow when flushing, a handle that sticks or requires excessive force, water leaking into the bowl when not in use, or visible cracks in the cartridge. If your toilet hasn't been serviced in several years, proactive replacement prevents mid-trip failures.
Q: Will this kit work with my specific Dometic toilet model?
A: This is a universal flush ball cartridge for most Dometic gravity-flush and pressurized toilet models. We recommend confirming your toilet model number before ordering. Our expert support team can help you verify compatibility—contact us with your model number.
Q: Is installation difficult, or do I need a technician?
A: Installation is straightforward for most RV owners. You'll need to shut off water, remove the old cartridge, and install the new one—typically a 15-minute job with basic tools. Your Dometic toilet manual includes step-by-step instructions, and our support team is available if you have questions.
