The Dometic flush ball seal is a critical component in your RV's waste holding tank system. This seal creates a watertight barrier in your Dometic R Series toilet, preventing leaks and odors from escaping into your RV. If you're experiencing water pooling around your toilet base or noticing unusual odors, a worn or damaged flush ball seal is likely the culprit.
