What Causes Discolored or Brown Water
Brown, yellow, or orange water is caused by rust — either from corroding galvanized supply pipes inside your home or from the municipal water main. If only hot water is discolored, the water heater is rusting internally. If both hot and cold are affected, your supply pipes or the city main are the source.
Boise-specific factor: Boise's North End and Bench neighborhoods have many homes with original galvanized supply pipes from the 1940s-1960s. These pipes corrode from the inside, releasing rust particles. United Water Idaho occasionally flushes fire hydrants or repairs water mains, which can temporarily stir up sediment and cause brown water citywide.
Signs You Have Discolored or Brown Water
Watch for these warning signs in your home:
- ✓ Brown, yellow, orange, or rust-colored water from faucets
- ✓ Discoloration is worse after the water has been sitting (morning)
- ✓ Only hot water is discolored (water heater issue)
- ✓ Water clears after running for 2-3 minutes
- ✓ Staining on laundry, fixtures, or toilets
Can You Fix This Yourself?
Run the cold water for 3-5 minutes — if it clears, sediment was disturbed and it's likely temporary. If both hot and cold are persistently brown, check United Water's website for main flushing schedules. If only hot water is brown, your water heater needs service.
If the problem persists or you're unsure, call a licensed plumber. Attempting complex repairs without proper tools can cause further damage and void warranties.

Frequently Asked Questions
Is brown water safe to drink?
Small amounts of rust aren't typically harmful, but consistently discolored water indicates pipe deterioration and may carry other contaminants. Don't drink visibly discolored water — use bottled water until the source is identified and fixed.
Will a water filter fix brown water?
A whole-house sediment filter catches rust particles, but it's treating the symptom not the cause. If your galvanized pipes are corroding, they'll eventually restrict flow enough to require replacement regardless of filtration.
