Plumbing service in Idaho
Call NowIdaho plumbing calls follow cold winters, irrigation and well water, and rapid growth in the Treasure Valley around Boise, Meridian and Nampa.
Idaho weather and your plumbing
Idaho winters are cold, with deeper and longer freezes in the mountains and the eastern part of the state. Summers are hot and dry in the Treasure Valley and Snake River Plain. Spring snowmelt raises groundwater in some valleys.
Season by season in Idaho
- Winter
- Exposed lines in crawl spaces, unheated garages and outdoor spigots freeze, and well houses need heat to keep pumps working.
- Irrigation season
- Pressurized irrigation and sprinkler systems run hard all summer, and backflow devices and outdoor lines need attention.
Problems the Idaho climate causes
Frozen well and pump lines
Cause: Long subfreezing stretches.
Result: Lines to the pressure tank or well freeze and the house loses water.
Do: Keep the well house heated and insulate exposed lines.
Hard water scale
Cause: Calcium-heavy aquifer water in the Snake River Plain.
Result: Scale builds up in water heaters and fixtures.
Do: Flush the water heater annually and consider treatment if scale is heavy.
Housing in Idaho
Much of the Boise area's housing was built in the last few decades, so newer PEX and PVC systems are common. Older homes in Boise's North End and in smaller towns have galvanized supply lines and cast-iron drains, and acreage properties around Kuna, Star and Emmett generally pump from a domestic well.
