Plumbing in Caldwell
Caldwell homes get water from the City of Caldwell’s deep groundwater wells. The city’s 2025 report measured arsenic up to 9.24 ppb, close to the 10 ppb limit, which is why many homeowners add drinking-water filtration.

Plumbing across Caldwell's 83605 and 83607
For anyone looking for a plumber in Caldwell, ID, it helps to know the city. Caldwell is the seat of Canyon County and one of the fastest-growing cities in the western Treasure Valley, and its plumbing reflects that growth. Across the 83605 and 83607 ZIP codes you find farmhouses on the edge of town, historic homes near downtown, and large subdivisions built in the last twenty years. Each comes with its own typical problems, which is why Caldwell plumbing work varies so much by neighborhood.
From a stopped-up kitchen drain off Cleveland Boulevard to a leaking water heater in a new build near the Vallivue School District, one call to (208) 802-8323 connects Caldwell homeowners with a local plumber.

Caldwell's water: arsenic, uranium and hard water
The City of Caldwell Water Department supplies homes from 15 deep groundwater wells. According to the city’s 2025 drinking water report, arsenic ranged from 3.90 to 9.24 parts per billion, below but close to the federal limit of 10, and uranium measured up to 20 parts per billion against a limit of 30. The water meets standards, but many Caldwell households choose reverse osmosis or under-sink filters for drinking water. The minerals in the water also make it hard water, which leaves scale in water heaters, fixtures and dishwashers. Plumbing in Caldwell, Idaho, is shaped by that water every day.

Older homes, irrigation and frozen pipes in Caldwell
Older housing is concentrated around downtown, Indian Creek Plaza and the College of Idaho campus. Some homes there still have galvanized supply pipe, which narrows with rust and scale until water pressure drops, and clay or cast iron sewer laterals that are prone to root intrusion. Newer neighborhoods tend toward PEX supply lines and PVC drains, where problems are more likely to involve fittings, fixtures and water heaters.
Irrigation is a Caldwell feature too. The Caldwell Municipal Irrigation District runs pressurized irrigation systems in many subdivisions, separate from drinking water, and homeowners are responsible for blowing out their own sprinkler lines before winter. With average January lows in the low to mid 20s, forgotten hose bibs and shallow lines in crawl spaces freeze every year.
