A camera inspection shows the lateral's condition.

Older laterals in Bay View, Riverwest and Washington Heights are often clay and collect roots from mature trees. A camera inspection shows whether a repeat clog needs cleaning or repair. MMSD handles regional wastewater, and the lateral belongs to the property owner.

Drains & sewer questions in Milwaukee

Why does a clog affect both units of my Milwaukee duplex?

Because they share one sewer lateral.

Are chemical drain cleaners safe to use?

They can damage older pipes and fixtures, and they make the job hazardous for the plumber if they don't work. A plunger or a drain snake is safer for a single slow drain.
