Plumbing Services in Boise, ID
Frozen Pipes
Boise mixes older neighborhoods near downtown and the North End with fast-growing subdivisions on the city's edges. Many newer subdivisions water lawns from a separate pressure irrigation system fed by the Boise River, and part of the east end still heats homes with natural hot water, so plumbers here meet two systems most cities don't have.

What Boise homeowners call plumbers about
- Frozen Pipe Repair
Cold snaps are routine in winter, and crawlspaces, garages and exterior walls are where supply lines freeze first.
- Sewer Line Repair
The private sewer line from the house to the city main is the owner's to clean and repair, and older neighborhoods have aging laterals.
- Backflow Testing
Homes with both drinking water and pressure irrigation have two systems on one lot, and cross-connections between them must be prevented.

Where Boise's water comes from
Boise's pressure irrigation water is diverted from the Boise River through canals and laterals, and is completely separate from the drinking water system; subdivisions built in the last 10 years are eligible to hook up. [1]
The Boise Warm Springs Water District, dating from 1891, supplies natural hot water for home heating to about 300 homes in the Warm Springs area; it is described as the oldest geothermal heating district in the nation. [2]

Boise plumbing questions
Is Boise's pressure irrigation water safe to drink?
No. It's untreated Boise River water in a separate system, meant only for lawns and gardens; never connect it to household plumbing.
Can a Boise plumber work on a geothermal-heated house?
Yes, for the domestic plumbing. Geothermal heating water in the Warm Springs area is supplied by the water district, so heating-loop issues go to the district first.
Who interprets the plumbing code in Boise?
The chief plumbing inspector in the city's Plumbing Section is the designated code official.
How old are Boise homes?
It varies widely: older homes near downtown and the North End, and much newer construction in outlying subdivisions. See the Census figures above.
