Sanitary or storm sewer sump pump wastewater lift station troubleshooting in Calgary A wastewater lift station job is to pump sanitary or storm sewer water up from the basement of a building to the main plumbing drain. During the past 22 years of providing vac truck service to clear sludge accumulation out of these sumps, we have become very experienced in working with submersible pumps and control panel testing. Control panel testing is also part of the job! Most often when we are called to an emergency where sewer water is backing up all over the basement floor, we have to be able to check the operation of the control panel by using a multimeter tool. This allows our plumbinng technicians to check for fuses, relays and the amperage draw of the pumps to make sure that everything is operating correctly electrically.
