What do plumbing codes typically require for water heaters installed in garages?

Plumbing codes typically require water heaters installed in garages to be elevated above the floor to prevent damage from flooding. This requirement is in place because garages can be prone to water accumulation and flooding due to rain or melting snow. If a water heater is located at floor level, it could be vulnerable to water damage, which might compromise its operation or lead to safety hazards such as electrical hazards or structural damage.

Elevating the water heater helps to ensure that it remains safe and functional even in the event of minor flooding. This practice is consistent with safety standards intended to protect both the appliance and the surrounding environment. It also helps to minimize any potential risks related to leaks and corrosion, as stored water can be a breeding ground for mold and other issues if the appliance is not adequately raised above potential water levels.

Therefore, the requirement for elevating water heaters in garages is crucial for maintaining safety, functionality, and longevity of the equipment.
