When a piston fails a head or set of heads will stay in the up position until the pump is turned off and then they will drop down. The pressure on the gauge of the water valve will be less than normal. Exception: the PCC system may have one, two, or three fixed nozzles that are opposite the main drain that are not cycled by the water valve.
