Frequently Asked Questions
Q: How do I know if my toilet base sheet needs replacement?
A: Signs include visible cracks, water pooling around the toilet base, soft spots in the flooring beneath the toilet, or a musty odor indicating water damage. If you notice any of these, the base sheet should be replaced promptly.
Q: Is this a difficult installation?
A: The base sheet replacement requires removing the toilet from the floor, draining the system, and unbolting the old sheet. Most RV owners can handle this with basic tools, though some prefer professional installation to ensure a perfect seal.
Q: Will this fit my older Dometic SH toilet?
