Annual Backflow Testing in Appleton

Proper drainage is designed for the relief port discharge.

The warranty period will be outlined in your service agreement, but generally, new installations come with a manufacturer's warranty on the device and our warranty on the installation.
No, backflow preventer testing and repair must be performed by a licensed and certified backflow prevention assembly tester. Wisconsin writes its own state plumbing code rather than adopting a national model code directly, and the state licenses plumbers. Improper handling can lead to serious water contamination.
No. Testing must be performed by a certified backflow tester using calibrated equipment. Water providers only accept reports from certified testers.
Backflow prevention is essential because of changing water pressures, main breaks and fire flow that can drop pressure suddenly, and the potential for cross-connections from irrigation systems or industrial processes. These factors increase the risk of contaminated water entering the public supply, making a working backflow preventer essential.
Constant dripping from the relief valve, low water pressure and visible cracks are common signs. Discolored water or a failed test notice also indicate a problem. Prompt repair keeps you in compliance.
