 P: 336 Do municipal water meters measure entrained air? upstream, maybe downstream, no way I can't imagine there is actually that much air I would be concerned that all it was doing is slowing down the flow, making it appear like your getting the same amount of water for less \$, but in actuality slightly reducing the water you use. If you are serious about saving water and money there are better ways. improved showerheads, always wash full loads of clothes, hand wash dishes, toilet water reductions, etc we even re-use the water that I get from the de-humidifyer heating the house for laundry water (we get ~5 gallons per day) don't skimp oin the showers, though, you can lose friends dr
