Yes, it’s a good practice to shut off the water supply at the water heater before turning off the main water supply. This helps prevent the water heater from draining and potentially damaging its components. Additionally, it reduces the risk of sediment buildup and helps maintain the water temperature in the tank until the main supply is restored. Always ensure the water heater is turned off before performing maintenance or repairs.

To confirm if a hot water heater is grounded, you can use a multimeter to test the continuity between the water heater's metal parts and a known ground, such as a grounding rod or the main electrical panel. If there is continuity, then the water heater is grounded. If you are unsure, it's best to consult a licensed electrician.
