Faqs / Does a water heater need to be level?

For many water heaters such as AO Smith, State, and Whirlpool you are better off letting the water heater sit directly on the floor even if it’s not perfectly level. The air intake for these water heaters are on the bottom of the tank which is protected by a pre-filter. If you raise up one of the edges to level the tank you are bypassing the pre-filter.
