How much water is saved by reducing pressure from 100 lbs to 50 lbs?

Reducing the pressure from 100 lbs. to 50 lbs.will result in a savings of approximately 1/3 because 1/3 less water flows at this lower pressure. Remember, there is more "push" behind the water at 100 lbs. than at 50 lbs. and most of this water is wasted. Almost twice as much water flows at 150 lbs. than 50 lbs., most of which is wasted.

Is there a water pressure reducing valve?

Yes. In 1971 the Washington Suburban Sanitary Commission conducted a test program in 2,400 dwelling units that has attracted widespread interest from more than 40 states and various foreign countries. One of the devices used in their conservation study was a water pressure reducing valves. It is interesting to note that their report concluded that in test locations using water pressure reducing valves, there was a water consumption reduction of 30% in October and November and 37% in December.

How does a PRV work?

Water entering the PRV is constricted and pushed into the valve’s inner chamber. The chamber is controlled by a spring-loaded diaphragm and disk. When water pressure fluctuates, the PRV helps maintain a constant flow and safe water pressure. A PRV will be functional only as long as the water supply pressure doesn’t drop below ...
