As technology advances we see the need of continuing our efforts to conserve water. We have recently changed our pre rinse valves from a 2.65 gpm, to a T & S Brass of 1.24 gpm, we made an entry in our blog about the potential savings with that valve. Two weeks ago we were given by National Grid, 3 Bricor BO64 PRV that restricts the flow of water to 0.64 gallons per minute, there is more pressure on the rinse and we are expecting to cut in a half our average pre rinse hot water consumption now, so we are going from 1.24 gpm to 0.64 gpm, we expect additional savings in water, sewer and gas.
