Frequently Asked Questions

Q: How do I know if my gravity flush control module needs replacement?
A: Signs include weak or no water flow during flushing, water continuously running into the bowl, or the flush valve not responding to control inputs. If your toilet won't flush at all despite having water supply, the control module is likely the culprit.

Q: Will this module work with my older Dometic toilet?
A: This module is specifically designed for Dometic 300, 310, and 320 series toilets. Check your toilet's model number (usually found on the bowl or in your RV manual) to confirm compatibility before ordering.

Q: Is professional installation required?
A: Most RV owners can install this module themselves if comfortable working with basic plumbing connections. The module connects to your existing water supply line and flush control system. Consult your Dometic toilet manual or contact our support team if you need guidance.
