A water purification system is configured to create a treated water for a home brewing operation. The water purification system includes a sediment filter, connected to an untreated water source. Untreated water flows from the untreated water source through the sediment filter creating a sediment filtered water. A carbon filter is connected to the sediment filter. The sediment filtered water flows through the carbon filter creating a carbon filtered water. A reverse osmosis system is connected to the carbon filter. The carbon filtered water flows through the reverse osmosis system and is segregated into a treated water and a rejected water. The treated water is distributed to the come brewing operation. A deionizing filter is connected to the reverse osmosis system with an automatic shutoff valve. The deionizing filter receives a second flow of treated water and creates a deionized water.
