the pump. If the system will not cycle freely below 1,500 PSI, see step 2.
Action

pressure to 2,000 PSI, the indicators in the indicator ports will signal the location of the

An indicator in the up position indicates pressure is in that outgoing line and signals
the blockage is in the area being served from this outlet, as shown in Figure 4.
