Frequently Asked Questions

How do I know if I need to replace my toilet pedestal base?

Common signs include visible cracks in the base, water leaking from around the pedestal area, toilet wobbling or feeling unstable, or discoloration and deterioration of the plastic. If you notice any of these issues, the pedestal base should be replaced to prevent further damage and potential floor leaks.

Is this pedestal base compatible with white Dometic 300 Series toilets?

No, this part number 385311085 is specifically for bone-colored toilets. If you have a white Dometic 300 Series toilet, you'll need the corresponding white pedestal base kit. The color must match your existing toilet for proper appearance and fit.

What's included in this pedestal base kit?

This is a complete pedestal base assembly kit that includes all necessary components to replace your existing base. The kit provides everything needed for the base replacement, though you may need standard tools and sealant for installation.

Can I install this pedestal base myself or do I need a professional?

Many RV owners with basic mechanical skills can replace the pedestal base themselves. The job requires removing the toilet from the floor, replacing the base assembly, and reinstalling with proper sealing. If you're comfortable with basic plumbing tasks and have the right tools, this is a manageable DIY project. However, if you're unsure about working with RV plumbing or floor seals, professional installation is recommended.
