• Record the readings of pressure gauge, vacuum meter, am-
peremeter, and if available flow rate gauge and compare
them with further readings under the same conditions (same
valve positioning, outlet-head, inlet water level etc.) and in-
vestigate the reasons for any discrepancies.
• Pressure gauge with three way cock: Only open the three-
way cock in order to obtain a gauge reading and close it im-
mediately afterwards.
• If pumping highly corrosive and/or abrasive media, the
components containing pressure should be inspected regu-
larly to avoid unexpected failure. The interval between in-
spections should be short initially and may be extended as
experience is gained.
