Minnesota plumbing is built around cold. Frost can penetrate several feet into the ground in a hard winter, so water service lines are buried deep, and basements are nearly universal. Even so, extended subzero stretches can freeze service lines and pipes along exterior walls, and spring snowmelt puts sump pumps to work.
Much of the housing in Minneapolis and St. Paul is older, with many homes built before World War II. That brings older drain materials, galvanized supply pipe in some homes, and, in some cases, lead service lines, which both cities have programs to identify and replace.

Deep frost and frozen service lines
During severe cold, even buried service lines can freeze. Utilities sometimes advise residents to run a faucet during extreme cold periods.
Basements and sump pumps
Spring snowmelt and heavy rain make sump pumps essential in many homes. Testing before spring is worthwhile.
Older housing stock
Older homes may have galvanized supply, cast iron drains and clay sewer laterals with root intrusion from mature trees.
Lead service lines
Some older homes still have lead service lines. Check with your water utility's service line inventory.

Minnesota plumbing questions
How do I keep pipes from freezing in a Minnesota winter?
Keep heat on and set no lower than the mid-50s °F when away, insulate pipes along exterior walls and rim joists, seal drafts, disconnect hoses, and follow utility advice about running water during extreme cold.
How do I know if I have a lead service line?
Check your utility's online service line inventory or look at the pipe entering your home near the meter. Lead is dull gray, soft and turns shiny when scratched; a magnet will not stick.
How deep are water lines in Minnesota?
Service lines must be below a deep frost line; in extreme winters, even buried lines can freeze, and cities sometimes advise running water to prevent freezing.
Is Minnesota water hard?
Much of Minnesota has hard water, and iron is common in well water.
Do Minnesota homes need sump pumps?
Many homes with basements rely on them during spring snowmelt and heavy rain.
Are wells and septic common in Minnesota?
Yes, in rural areas. Minnesota regulates septic systems, and many counties require compliance inspections at sale.
What should I do if my water service line freezes?
Contact your utility and a plumber; thawing buried lines requires specialized equipment.
Do Minnesota cities have lead service lines?
Some older homes do. Minneapolis and St. Paul have run replacement programs; check yours.
