Frequently Asked Questions

How do I know if I need to replace my discharge tube?

Common signs include water or waste leaking around the toilet base, visible cracks in the tube, persistent odors even after cleaning, or difficulty flushing. If you notice any of these symptoms, inspect the discharge tube for damage or deterioration.

Can I install this discharge tube kit myself?

Yes, most RV owners with basic mechanical skills can replace this component. You'll need to remove the toilet from the floor, disconnect the old tube, install the new tube with the included hardware, and reseal the toilet base. Always turn off water supply and empty the holding tank before beginning work.

Will this fit both white and bone-colored Dometic toilets?

Yes, this discharge tube kit is compatible with all color variations of Dometic 8600 and 8900 series toilets. The tube is a functional component located beneath the toilet bowl and doesn't need to match the toilet's exterior color.
