Plumbing service in Iowa
Call NowIowa plumbing contends with deep winter frost, basements in most homes, river flooding in places and rural water from private wells.
Iowa weather and your plumbing
Iowa has cold winters with deep frost and strong winds, and hot, humid summers with severe thunderstorms. Spring snowmelt and heavy rain can flood rivers, including the Cedar, Des Moines and Mississippi.
Season by season in Iowa
- Winter
- Frost goes deep, and water services, outdoor spigots and pipes in unheated spaces freeze during long cold spells.
- Spring flooding
- Snowmelt and heavy rain raise rivers and groundwater, pushing sump pumps hard and backing up floor drains.
Problems the Iowa climate causes
Frozen water service lines
Cause: Deep frost in hard winters.
Result: The line from the street or well freezes and stops water to the house.
Do: Keep a trickle of water running in extreme cold if your service has frozen before, and call a plumber to thaw it.
Basement backups
Cause: River flooding and heavy rain.
Result: Floor drains back up and sump pumps run constantly.
Do: A backwater valve on the main sewer line stops city water from flowing back into floor drains.
Housing in Iowa
Most Iowa homes have full basements. Older homes in Des Moines, Cedar Rapids and Davenport often have cast-iron and clay drains, and many rural homes rely on private wells, sometimes with high nitrate or hardness levels that call for treatment.

Iowa questions
Can my water line freeze underground in Iowa?
Yes, in hard winters when frost goes deeper than usual, especially under driveways and bare ground. A plumber can thaw the line and discuss deeper burial or insulation.
Should I test my private well in Iowa?
Yes. Regular testing for bacteria and nitrate is recommended for private wells, especially in agricultural areas.
How do I check a plumber's license in Iowa?
Iowa's Plumbing and Mechanical Systems Board licenses plumbers, mechanical professionals and contractors statewide under Iowa Code chapter 105. Plumbing work in Iowa requires the appropriate state license.
