DIY vs. professional installation in Flower Mound
Texas law (TSBPE) requires a licensed plumber for any gas water heater installation. Electric water heaters can be DIY-installed, but doing so voids most manufacturer warranties.

For Flower Mound homeowners, hiring a licensed pro ensures safety, code compliance, and warranty protection, especially given the higher home values and strict local permitting.
