Score is Grade A Plumber's own 0–1,000 rating, computed from review quality and volume, recent activity, owner replies and a verified Michigan licence. Google ratings and counts are shown as reported by Google and are not this site's own rating. A green ✓ means we matched the company to a current Michigan plumbing licence; “verify” means it is not in our register extract yet — check the state record. A blank is not a claim that a company is unlicensed.
What to know about sump pump work in Michigan
Basements flood from two different sources: groundwater, which is a sump problem, and a sanitary sewer backup, which is a backwater-valve problem. The EPA lists blockages, pipe line breaks, and power failures at pump stations as common causes of a sanitary sewer backup into a home. [U.S. EPA]
Sump and backwater work is plumbing work under the Michigan Plumbing Code; a backwater valve in particular must be installed and accessible to code to function in a backup. [LARA Bureau of Construction Codes]
Oakland County's Water Resources Commissioner recommends two separate fixes for basement flooding: a sump pump to keep groundwater out, and a sewer backflow (backwater) valve to stop sanitary sewage from backing up through the drainpipes. [Oakland County Water Resources Commissioner]
Before a storm, DTE Energy recommends checking that a sump pump works and has a battery backup — a power outage during heavy rain is exactly when a primary pump is most likely to fail. [DTE Energy]
Common questions
Do I need a backup sump pump?
If your basement floods during power outages, yes — a primary sump pump stops the moment the power does, which is often exactly when the storm is driving the most water. A battery backup pump runs through the outage. [DTE Energy]
What is a backwater valve?
A one-way valve on your sewer lateral that closes when the city sewer surcharges, stopping sewage from backing up into the basement. It is separate from the sump system and solves a different kind of flooding. [Oakland County Water Resources Commissioner]
