| As shown in figure "A" and "B" of the illustration, the potable water pump is short cycling by the action of the pressure switch as a result of an unusually high level in the potable water hydro pneumatic header tank. What is most likely the cause? Illustration EL-0043 |
| A) The pressure switch differential setting is set excessively high and the differential must be decreased. |
| B) The pressure switch range adjustment is set too low and must be set higher. |
| C) The potable water hydro-pneumatic header tank has too much compressed air and some must be bled off. |
| D) The potable water hydro-pneumatic header tank is in need of recharging with compressed air due to absorption of air into the water over time. |
