DIY vs. Call a Pro
You can flush sediment from the tank by connecting a garden hose to the drain valve. For electric heaters, you can test and replace heating elements with basic tools. Always turn off power/gas first.
Call a professional when:
Call a plumber for gas line issues, major leaks, or if you smell gas. Also call if the unit is over 10 years old — repair vs replacement analysis is valuable.
