The pressurized water treatment apparatus has an inlet port, a check valve, a control valve assembly, an air injection body, a one-way pressure sensitive valve, a treatment tank body, water treatment filter media, gravel media, a distributor basket, a riser tube, and an outlet port. The pressurized water treatment apparatus may be used in four configurations: the normal flow configuration, the backwash configuration, the air injection configuration, and the rinse configuration. When compared to the prior art, the distributor basket and increased total flow area prevents iron and iron bacteria buildup, increasing the efficiency of the water treatment process and use in the backwash configuration, and reducing maintenance and replacement costs. ## Claims ### Claim 1 A pressurized water treatment apparatus comprising, an inlet port, wherein the inlet port is configured to be connected to a pressurized fluid source;
