Certified Backflow Testing & Repair
Backflow preventers protect your drinking water from contamination by preventing irrigation water from flowing back into the public water supply. Idaho requires annual testing to ensure these devices work properly.
What is Backflow Prevention?
A backflow preventer is a mechanical device installed where your irrigation system connects to your water supply. It contains check valves that only allow water to flow one direction—into your sprinkler system, not back into your home or the city water supply.
Idaho Backflow Testing Requirements
If your irrigation system is connected to a potable water supply, Idaho requires annual backflow testing by a certified tester. Your water provider will send a notice when testing is due. Failure to comply can result in water service disconnection.
Our Testing Process
- Inspect backflow preventer for visible damage
- Conduct certified pressure test
- Document results on official report
- Submit paperwork to water provider
- Recommend repairs if test fails
Backflow Testing Costs
Backflow testing typically costs $75-$150. If your device fails the test and needs repair or replacement, additional costs will apply depending on the issue.
Types of Backflow Preventers
- Double Check Valve (DC): Most common for residential irrigation
- Reduced Pressure Zone (RPZ): Required for higher-risk applications
- Pressure Vacuum Breaker (PVB): Older style, common in existing systems
