Frequently Asked Questions
How do I know if my toilet seals need replacement?
Signs include water pooling around the toilet base, sewage odors coming from the bathroom, or visible leaking into the waste tank. If your toilet has been in use for several years, preventive replacement is a good idea.
Is this kit easy to install myself?
Yes. Most RV owners can replace the seals in 30–45 minutes with basic tools. The kit includes all necessary components. If you're uncomfortable working on your toilet, a technician can install it quickly.
Will this kit work on my older Dometic toilet?
This kit is designed for Dometic 300, 310, and 320 series toilets. Verify your model number on the toilet bowl or in your RV manual before ordering to ensure compatibility.
