Posted on June 12, 2020 by Diana BlakneyCity water pump The City put this pump in for the farm because the gravity system no longer provided the requisite water pressure. The pressure gauge under the grey-colored cylindrical thing is the house pressure gauge. The gauge in the upper right hand corner is the City pressure. When the pressure to the house is too low, the pump (the rectangular machine under the electric plug) kicks in. The red handles are for workers only. They turn off the water when work needs to be done. The interior light is on a timer.
