PROBLEM TO BE SOLVED: To provide easy-to-use water storage equipment which stops water supply by detecting an abnormal water level. SOLUTION: This water storage equipment comprises: a water storage vessel 1; a water-level detecting means 9 for detecting a plurality of water levels in the water storage vessel 1; a water supply means 5 which is provided in a water supply path 6 to the water storage vessel 1 from a water service pipe 14 so as to control water supply; a drainage pump 4 which discharges the water in water storage vessel 1; a water-level abnormality stop means 12 for stopping the water supply by determining that the water level is abnormal when the water level in the water storage tank 1 becomes as high as or higher than a first predetermined water level; and an automatic water discharge means 11 for discharging a specified quantity of water by driving the drainage pump 4 on the occurrence of an abnormality in the water level. Thus, when the water supply is stopped due to the abnormal water level, the specified quantity of water is automatically discharged by the drainage pump 4 so as to enable an automatic return from a water supply-stopped state caused by the abnormality in the water level, and an improvement in the usability of the water storage equipment.
