Wet wells pumped out and pressure washed at least twice a year, or more often if necessary, to prevent solids and grease build-up. Build-up of solids can create odors and damage the pumps.
Pull and inspect submersible pumps taking close note of the condition of the impeller and suction port. Worn impellers create more runtime on the pumps, consuming more energy than necessary and causing premature failure of the pump motor.
Inspection of check valves to prevent back flow from the force main to the wet well.
Clean and inspect floats to insure proper performance. The buildup of grease prevents floats from working properly.
Inspect and exercise the electrical control panel, including the light and alarm systems. Thermography will be used to determine if motor starters and circuit breakers are performing properly and to identify poor connections.
Note and record hours from hour meters on each motor to provide an accurate record of how often each pump is cycling. Differences in run times greater than 10% may be an indication of a problem with one of the pumps.
Amp and voltage readings will be taken on each pump motor and recorded. If the amp readings do not meet the manufacturer's specifications, it could be an indication that debris is lodged in the impeller, or that water has entered the motor housing. Early detection of either symptom can save the pump motor from catastrophic failure.
Perform a Megohm test on the pump motors to determine the condition of the motor winding insulation. By utilizing regular Megohm testing, a base line reading can be established and used over time to determine if the windings are deteriorating, eliminating the chance of catastrophic failure and wet well downtime.
Record and document all findings, present a written report to the owner after each maintenance period, and post the reports to the Internet on a secure server for safe keeping and instant access 24/7/365.
