Frequently Asked Questions
Q: How do I know if my toilet pump body needs replacement?
A: Signs include weak or no flushing action, slow waste evacuation, unusual grinding or squealing noises from the toilet base, or water not being drawn into the bowl. If your toilet has lost suction or won't prime, the pump body is likely worn.
Q: Is this a complete rebuild kit or just the pump body?
A: This is the pump body assembly kit. It includes the core pump mechanism and internal components needed to restore flushing function. You may need additional seals or gaskets depending on your toilet's condition — we recommend inspecting the full toilet assembly during rebuild.
Q: Will this work on my Dometic 300 series toilet, or do I need a different part?
A: This kit is designed for Dometic 300, 310, and 320 series toilets. Verify your model number on the toilet base or in your RV manual before ordering. If you have a different series (like 500 or 600), you'll need a different pump body kit.
