PUMP VACUUM TEST

To perform the pump vacuum test do the following:

1.Remove the pump fill cap, and fill the pump with water.

2.Start the engine as outlined in the initial start-up section, and wait for the pump to begin pumping.Confirm engine is operating at 3,000 RPM's

3.As shown in Figure 15, place a water hose inside the discharge opening of the pump, and turn on the water. This flow of water into the discharge opening will prevent the pump from running dry.

4.Place the Pump Vacuum Tester over the pump inlet opening (Figure 15) with the vacuum gauge facing upwards. It may be necessary to apply a small amount of water around the rubber seal of the vacuum tester to make a good suction fit.

5.Check and make sure that there are no air leaks between the vacuum tester and the inlet port on the pump. If air leaks are present re-seat vacuum tester.

6.Run the pump for a few minutes while monitoring the vacuum gauge. A pump will lose approximately one foot of suction lift for every 1,000 feet of elevation. Depending on the elevation, the gauge should read between 20-29 in. Hg. (inches of mecury). This is an indication that the pump is working correctly.

7.If the vacuum tester gauge indicates a reading below - 20 in. Hg, it can then be assumed that the pump is not functioning correctly, and corrective action needs to be taken.
