Q: Will this kit work on my specific Tiara model?
A: This kit is designed for Tiara models with Dometic systems. Verify your model year and system type before ordering, or contact our expert support team for confirmation.

Q: What tools do I need to install this seacock switch?
A: Basic plumbing tools (adjustable wrench, screwdrivers) and marine sealant are typically required. Consult your RV manual or our support team for detailed installation guidance.
