Frequently Asked Questions
Q: Will this cap fit my Dometic toilet if I don't have a HydroFlush model?
A: No. The HYD-J11 is specifically designed for Dometic HydroFlush systems. Check your toilet model number before ordering to ensure compatibility.
Q: How do I know if my hydraulic cap gasket needs replacement?
A: Look for visible leaks around the hydraulic connection, low system pressure, or difficulty flushing. A worn gasket is a common cause of these issues.
Q: Can I reuse the old gasket if I just replace the cap?
A: We recommend replacing both the cap and gasket together. The gasket compresses over time and loses its seal effectiveness, even if the cap appears fine.
