摘要： A water pressure reducer using compression forces with an inverse upstream to downstream pressure relationship, and a method of operating the same, is disclosed. The water pressure reducer may include a housing defining first and second chambers separated by a membrane. Water pressure within the second chamber biases the membrane in a first direction opposite the force of a spring within the first chamber, decreasing flow through a valve seat and into downstream water lines. Decreased water pressure within the second chamber biases the membrane in a second direction, increasing flow through the valve seat and water flow to downstream pipes. Biasing of the membrane in the first direction and the second direction can occur continuously as water pressure from the upstream water line increases and decreases.
