We service a 2 pump sewage ejector system on a 20 unit apartment building about every 6 months.
Used to be fouled with lard/grease, but last couple years it has been sanitary wipes.
The system needs grinder pumps.
It has a control panel that alternates pumps.
3 floats control both pumps. stop float/start float/ alarm float.
Pumps are only 120v each.
after the controls there are 2 quick disconnects with fuses.
Couple weeks ago we could not respond to and alarm. (pump failure ) so management called someone else.
A$$holes bypassed all the controls and safety disconnects.
Installed a box to hold 2 GFI outlets.
Removed the 3 floats.
Then the cut the power cords and spliced plug connectors .
Then they added floats to each pump with piggy back plug power cords.
1 week later we're pulling the pumps, impacted with sanitary wipes.
splices they made on power cords were in the water ( when the sump filled )
So even after we cleared the pump, they would trip the GFI.
That is a really nasty job and the residents have been notified several time.
Some of these photo are from previous cleaning
