How much does backflow testing cost for residential properties?

Backflow testing for a home is quoted case by case. Price depends on the number and type of backflow preventers, device size, access, and any needed repairs or retesting. A trained technician will inspect and test each device. You’ll get an upfront price before work begins, and the final cost is confirmed on site in Chicago and nearby suburbs.

Quick prep:

• Count how many backflow devices you have.
• Note where each device is located.
• Have any prior test tags or reports ready.
