Cast-iron stacks in Whittier and Uptown
Categories: Drains & sewers, Twin Cities
Whittier and Uptown still live on cast-iron stacks. The rust looks like a clog on a cheap camera. It is scale. A closet auger opens a hole for a weekend. The next Saturday the same toilet is back. That is not bad luck. That is the pipe wall.
We run hydro jetting after the first return visit when two fixtures share the stack. Pressure comes from the video, not a default PSI. Fragile sections get a different nozzle or a replacement conversation. sewer line repair is the page when the camera shows a belly or a broken hub.
1920s duplexes share a stack the way they share a porch. Your downstairs neighbor’s ceiling is the first report. We isolate one address. We do not take a whole building down without the owner. commercial plumbing covers the apartment version of this call.
Chemical dump is how you turn a 90-year-old fitting into a hole in the basement. Stop. Clogged toilet if it is one bowl. Sewer backup if a tub is involved. drain cleaning for the residential visit.
Linden Hills and Mac-Groveland have the same iron, nicer yards. trenchless sewer is on the table when the boulevard cannot take a trench. Camera first. Always.

Questions from this kind of call
Will jetting break old iron?
We set pressure from the camera. A collapsed hub is a replace, not a jet.
Is this a main or a stack?
If only upstairs baths are slow, start at the stack. If a floor drain is up, it is the main.
