Frequently Asked Questions

Q: How do I know if my valve base needs replacement?
A: Look for water or propane leaks around the valve connection, visible cracks in the plastic or metal base, or difficulty turning the valve handle. If you notice any of these signs, replacement is recommended to prevent system failure or leaks.

Q: Will this valve base fit my specific RV model?
A: This is a Dometic OEM part with a 1/4" connection. It fits most Dometic valve assemblies in water systems, refrigerators, and propane regulators. We recommend confirming your current part number (290000135) matches before ordering, or contact our support team with your RV model for verification.

Q: Is this a direct replacement, or do I need additional parts?
A: This is a direct OEM replacement for the valve base only. Depending on your system, you may need to replace the valve stem, handle, or seals separately. Inspect your existing assembly to determine what components need replacement.
