Abstract: Provided is a water purifier including: a raw water flow path into which water flows from outside; a filter configured to filter the water introduced from the raw water flow path; a purified water flow path configured to discharge the water having passed through the filter; a drain flow path through the water discharged from the filter through the wastewater flow path is discharged; a resistance valve configured to reduce a flow rate of the drain flow path; a first connection flow path connecting the raw water flow path to a downstream side of the resistance valve on the drain flow path; a second connection flow path connecting the purified water flow path to an upstream side of the resistance valve on the drain flow path; and a tank arranged on the second connection flow path. During washing of the filter, the water stored in the tank flows into the filter via the upstream side of the resistance valve on the drain flow path, and the water flowing into and through the filter is discharged to the outside through the raw water flow path, the first connection flow path, and the downstream side of the resistance valve on the drain flow path.
