Backflow Testing Services
Crimson Copper Plumbing provides backflow testing and repair services to homeowners in Chaska and Shakopee, MN. Our plumbers have the equipment and certifications to test your backflow prevention devices and make repairs when something goes wrong. We keep your water supply protected from contamination and help you stay compliant with local codes.
Most homes in MN with irrigation systems or fire sprinkler lines are required to have backflow preventers installed. These devices stop water from backflowing into your main supply line, ensuring your supply stays clean and uncontaminated!
When they fail, you risk pulling contaminated water back into the pipes you drink from. Some homeowners water their lawns throughout the season without realizing that the system isn’t protecting their drinking water.

Why You Need Backflow Testing
Annual backflow device testing is required in most municipalities. Without proper testing and documentation, you risk fines or water service interruptions.
The testing process is simple: we shut off the water supply, connect gauges, and run pressure checks, which typically takes about 20 minutes if everything passes. If we find a problem, we’ll explain what’s failing and what needs to be replaced.
Signs Your Backflow Preventer May Need Repair
- Water pressure dropped suddenly in your sprinkler zones
- Device leaking from the relief valve
- Visible rust or corrosion on the brass fittings
- You failed your last inspection and got a notice
- Check valves not closing when you shut off the supply
Backflow devices installed outdoors face Minnesota’s harsh freeze-thaw cycles. Below-zero temperatures are common during winter, which can crack the bonnet or damage internal springs if the unit wasn’t properly winterized.
Our hard water also builds up scale on the rubber seals until they stop closing tight. Some units have check valves so caked with mineral deposits that they barely move. Once that happens, the only fix is replacement parts or a new assembly.
When to Call for Backflow Repair
If you received a failed test notice from your inspector, don’t wait. You usually have a short window to make repairs and get retested before penalties kick in.
For a failed test, we’ll replace the check valves, springs, and seals, then retest to make sure everything meets code. The repair work typically takes an hour, and you’ll have documentation to submit to your water authority.
Crimson Copper Plumbing has served Chaska and Shakopee homeowners for years. We’re licensed and carry the test equipment required by MN regulations.
