Frequently Asked Questions

Q: Will this kit fit Aqua-Magic Style Lite or Style Plus toilets?
No. The 42209 waste ball kit is designed specifically for Style II and Residence toilets. Other series use different waste valve designs.

Q: Does replacing the waste ball fix odor issues?
Yes — a worn or damaged waste ball often allows sewer gases to escape; replacing it with the proper seal restores odor containment.

Q: Is this an OEM Thetford part?
Yes, 42209 is the genuine factory replacement waste ball kit for the specified models.

Q: Can I install this without removing the toilet?
It depends on your RV layout — access is required to the waste valve housing. Removal may be necessary for some installations.

Q: How often should I inspect or replace the waste ball/seal?
Inspect when leaks, odors, or flushing problems occur. Under heavy use, a seal may need replacement every few years — the waste ball itself typically lasts longer.
