Frequently Asked Questions

Q: How do I know if my flush ball seal needs replacement?
A: Common signs include water pooling under the toilet, a weak or incomplete flush, or visible water dripping from the flush valve assembly. If your toilet is over 5 years old and experiencing these issues, the seal is likely worn.

Q: Is this part compatible with all Dometic toilet models?
A: This seal is specifically designed for Dometic 300 and 310 series toilets. Check your toilet's model number (usually found on the bowl rim) before ordering to ensure compatibility.

Q: Can I install this myself?
A: Yes, this is a straightforward replacement that most RV owners can handle with basic tools. You'll need to access the flush mechanism under the toilet bowl and remove the old seal, then install the new one. Our support team can provide installation guidance if needed.
