49、sers have found the addition of a compound pressure gage near the pump inlet port to be a useful diagnostic tool (Item 17, Fig. 1).However, exercise care to ensure that any ports added to the inlet line do not become air ingestment points.NOTE 7The use of a solenoid valve, finger screen or other device which restricts pump inlet flow is discouraged. Inlet restrictions adversely affectpump performance.NOTE 8When tubing is used for the pump inlet line, some users prefer to use a ra
