Keep a tested sump pump with battery backup, install a backwater valve on the main line, and plug unused floor drains when river levels rise.
How do I check a Fargo plumber?
Verify the license with the North Dakota State Plumbing Board.
Can Fargo service lines freeze?
In very deep cold, shallow or poorly insulated sections can. Keeping water moving and heat on helps, and a frozen service line needs a professional.
