A gas leak is a situation where natural gas or propane, which are used to power appliances such as hot water heaters, escapes from its intended pipeline or container. A gas leak can occur due to a number of reasons, such as corrosion, damage to the pipe or equipment, and improper installation.
It is important to detect a gas leak on a hot water heater because a gas leak can pose a serious safety hazard.
