Yes. Even a small leak can turn into a serious problem if it’s not handled quickly. Water can come into contact with electrical parts or gas controls, creating a shock or fire risk. A slow leak can also soak walls, floors, or ceilings, leading to mold and long-term structural damage. If you notice any signs of leaking, turn off the water supply and power to the heater, and call a licensed plumber to inspect it right away.
