    Pounds to inches

    water column is this there are 27.6 inches water column to a pound of pressure .

    All you need is a maxitrol regulator which will reduce pounds to inches and get one that can operate in the range of 6" W.C. mid point.

    Why is the pressure to the unit 20"? Most system regulators before the meter drop pressure from pounds to about 6" to 7" W.C.
