Answerif the power goes off water will not go all over the floor, however the water will possibly run into the air pump which on start could start an electrical fire. you should have check valve in the air line between the air pump and the air line going into the tank. these can be purchased at a local retailer and even walmart has sold them. they are inexpensive and can prevent damage.best of luck
