Frequently Asked Questions
Q: How do I know if my bellows pump needs replacement?
A: Signs include weak or no flushing action, difficulty creating suction, unusual grinding sounds during flushing, or water not moving into the holding tank. If your toilet worked fine before and suddenly lost pressure, the bellows pump is typically the problem.
Q: Will this pump work on older Dometic toilets?
A: This pump is designed specifically for Dometic S and T series toilets. Check your toilet's model number (usually found on the bowl rim or underside) to confirm compatibility before ordering.
Q: Is installation difficult?
A: Most RV owners can replace the bellows pump with basic tools. It typically involves disconnecting water supply lines, removing the old pump assembly, and installing the new one. Your RV manual will have specific steps for your model.
