TO TEST AND ADJUST GAS (WATER COLUMN [W.C.]) PRESSURE

There are two (2) types of devices commonly used to measure water column pressure. They are spring/ mechanical type gauges and manometers. The spring/mechanical type gauge is not recommended because it is easily damaged and not always accurate. A manometer is simply a glass or transparent plastic tube with a scale in inches, which when filled with water and pressure is applied, the water in the tube rises, showing the exact water column pressure.
