Backflow Testing in Louisville, CO

What happens when you call

You'll be connected with an independent plumber who serves Louisville. Say whether you have a reminder from BSI, a failed test or a leaking device. Ask whether the tester files reports through BSI, since that's how Louisville collects them. Property owners with questions about their account can reach BSI at 888-966-6050, and testers use 800-414-4990. If the plumber finds a problem, they'll explain whether the device can be rebuilt or needs replacing, and retest it after the work.

What shapes the cost

• Visit type. Routine test, repair and retest, or a full replacement.
• Assembly design. Reduced pressure assemblies have more parts than double checks or vacuum breakers.
• Freeze damage. Split bodies need new assemblies.
• Rebuilt homes. Newer construction may have devices in different locations than original homes did.
• Permits and inspections. Louisville's Building Safety Division issues permits and performs plumbing inspections.

Louisville's water and backflow setup

Louisville runs its own water utility with two treatment plants and disinfects with chlorine. Because the city owns the system, it sets the backflow rules, and it has handed day-to-day administration of its cross-connection program to Backflow Solutions, Inc. Few homes are on wells; the municipal system serves the city.

The fact sheet doesn't spell out which property types must test or how often, so if you're unsure, ask BSI or Louisville Public Works at 303-335-4608. Commercial buildings along Main Street and in the business parks near US-36 and the Northwest Parkway are the likeliest to have required devices. Hundreds of homes were rebuilt after the December 2021 Marshall Fire, and many of those came with new irrigation systems and new backflow devices.

The former coal-mining town has a mix of historic downtown homes and newer subdivisions around Harper Lake and Coal Creek. Freezing nights hit exposed sprinkler devices everywhere, so fall drain-downs matter.

If you own a rebuilt home, the paperwork from the builder may show the make and model of the backflow device installed with the new irrigation system. Keep that with the house records. It makes a future rebuild faster, because the plumber can bring the right kit instead of identifying parts on site.

Before the plumber arrives

• Have any BSI reminder or account number
• Locate the device and clear access
• Know where the irrigation shutoff is
• Note when the home was built or rebuilt
