PROBLEM TO BE SOLVED: To provide a water treatment equipment which sterilizes water fed from a water supply inlet of a water supply system in a building etc. efficiently by electrolysis treatment to keep the water quality while keeping the airtightness of a water supply tank and preventing a gas storage problem. SOLUTION: An automatic gas vent valve 13 for discharging a gas generated by the electrolysis treatment to the outside of a treated water passage 100 is connected onto the downstream side from an electrolysis treatment mean 11 of the treated water passage 100 connected with a water supply tank 2, and a function for accelerating the inflow of gas into the automatic gas vent valve 13 by stopping operation for a while is given. The gas generated by the electrolysis treatment can be collected in the automatic gas vent valve 13 by buoyancy of the gas during temporary stopping of the apparatus, and discharged outside of the treated water passage 100, which can surely prevent the gas from being stored in the water supply tank 2 while keeping the airtightness of the water supply tank 2.
