Riverwest Plumbing Help
Riverwest is one of the places where Milwaukee’s Polish flats are thickest: cottages that were raised and given a second unit in the basement, often years after the house was built.

Why Polish flats are their own plumbing problem
When a cottage was lifted and a basement apartment added, the plumbing for that unit went in later, sometimes much later, and sometimes by the owner. The lower unit sits close to the sewer, with fixtures barely above the level of the lateral. It is the first place water appears in a backup, and a floor drain or a basement shower can be lower than a backwater valve would need to protect without careful placement. If you own one, find out how the lower unit drains before the next big storm, not after.
One service, two households
Most Riverwest duplexes and Polish flats share one water service, one meter and one lateral. That matters for lead, because a required replacement involves the whole building, and it matters for billing, because one tenant’s running toilet is everyone’s water bill. Separate shutoffs for each unit are worth having, and they are a reasonable small job to ask for at the next visit.
Who handles what
Riverwest is inside the City of Milwaukee, so Milwaukee Water Works handles the lead service line programme and its no-cost terms for required replacements at one to four unit homes with no commercial use. Because these are two-family buildings, the city’s owner-occupant permit exception for one-family homes does not apply, so plumbing work goes through a licensed plumber who pulls the permit.

Winter in a raised cottage
Raising a house leaves a tall foundation wall and, often, a rim joist with little insulation. Supply lines that run along that wall to the upper unit are exposed to the cold on one side. If the upper unit loses water on the coldest mornings while the lower unit is fine, that run is the likely freeze point.

Riverwest questions
Can I do my own plumbing in my Riverwest duplex?
The City of Milwaukee’s owner exception is for the owner-occupant of a one-family building. In a duplex, plumbing work goes through a licensed plumber with a permit.
Who pays for a lead line replacement on a shared service?
For a required replacement at a 1–4 unit home with no commercial use, Milwaukee has charged owners nothing since early 2024. Confirm current terms with Milwaukee Water Works.
