An apparatus to provide purified water to one or more electrolyzers for manufacture of hydrogen can include a polisher positioned to receive at least a minimum flow of water from a demineralization unit to purify the water and output the purified water to at least one electrolyzer of an electrolyzer house. The flow of water can be adjusted to maintain a minimum flow of water passing through one or more beds of the polisher while accounting for the demand of water at the electrolyzers. Flow adjustments can be made between providing all the purified water to the electrolyzers during high demand operations to other configurations in which little or no purified water is fed to the electrolyzers and, instead, that water is recycled back to the water demineralization unit.
