Frequently Asked Questions
Q: How do I know if my tank head needs replacement?
A: Signs include visible cracks or damage to the tank head, persistent leaks around the tank area, sewage odors that won't go away despite cleaning, or water pooling under your RV near the waste tank. If your tank is over 10 years old and showing any of these symptoms, replacement is recommended.
Q: Will this kit fit my specific RV model?
A: This kit is designed specifically for Dometic 28HTS holding tank systems. Verify your tank model number before ordering. If you're unsure, check your RV's waste system documentation or contact our expert support team with your RV's year and model.
Q: Is professional installation required?
A: While many experienced RV owners can handle this replacement, tank work can be messy. We recommend consulting your RV's service manual or having a professional technician perform the installation to ensure proper sealing and system integrity.
