Backflow Testing and Certification Services
Backflow prevention devices are designed to protect potable water from contamination caused by reverse water flow. When these devices fail, pollutants from irrigation systems, commercial equipment, or plumbing malfunctions can enter the main supply—posing a serious health risk.
To prevent this, the City of McKinney and many surrounding DFW municipalities require annual backflow testing by a licensed, certified professional. At Blue Otter Plumbing & Drain, we make that process simple. We offer:
- Residential and commercial backflow testing
- Documentation and certification submission to your local municipality
- Photo documentation of each device tested
- Fast certificate delivery for inspections or permitting
We are certified to test all types of backflow prevention assemblies, including those installed on irrigation systems, soda machines, fire suppression systems, and commercial plumbing configurations.
