Minneapolis plumbing questions
Do I need a water softener in Minneapolis?
Often not. The city's treated water tests around 4.5 to 5.5 grains per gallon. Homes on private wells in the suburbs are a different story.
How do I stop pipes freezing in a Minneapolis winter?
Insulate and seal around pipes on exterior walls, keep heat on when away, disconnect hoses, and on the coldest nights let a faucet on an outside wall drip. See frozen pipe repair.
