Our Backflow Prevention & Testing Services in Anoka, MN

We offer a comprehensive range of backflow prevention services to meet the needs of Anoka homeowners, commercial property managers, and businesses. Each service is performed by our certified team.

Lawn Sprinkler Backflow Testing

Annual mandatory pressure testing for residential lawn irrigation assemblies to maintain Anoka County compliance.

RPZ Valve Testing & Repair

Reduced Pressure Zone (RPZ) backflow assemblies are high-hazard protection devices. We test, clean, and rebuild them.

Double Check Valve Assembly (DCVA)

Testing and certification of double check valves commonly used in low-hazard fire sprinkler systems and domestic water lines.

Backflow Valve Rebuilds

We replace worn rubber seals, springs, guide assemblies, and relief valves inside failed backflow units using factory OEM kits.

New Backflow Valve Installation

Expert layout and installation of new backflow prevention valves for lawn systems, pools, boilers, and commercial connections.

Winterization & Blowout Service

Protect outdoor backflow valves from freezing temperatures. We blowout irrigation lines and drain assemblies in late autumn.

Commercial Backflow Certification

Large-scale commercial and industrial backflow testing, compliance reporting, and repair for local businesses.

Thermal Expansion Tanks

Installing backflow preventers creates a "closed loop" plumbing system. We install expansion tanks to prevent pressure spikes.

Anoka County Backflow Compliance & Regulations

Under Minnesota Department of Natural Resources (DNR) regulations and Anoka County ordinances, any water connection that presents a risk of cross-contamination must have an approved backflow preventer installed. This includes lawn irrigation systems, fire sprinkler lines, commercial boilers, and large swimming pools. These devices must be tested annually by a licensed ASSE-certified tester, and the test report must be filed with the water purveyor (typically Minnesota American Water or the City of Anoka water department) to avoid service termination.

⚖️ Backflow Prevention: Can You DIY It?

We believe in honesty. Some plumbing tasks are safe for homeowners — others are dangerous or illegal without a license. Here's the real breakdown.

Situation DIY Verdict What You Need to Know
Testing your own backflow preventer Must be licensed — it's the law Minnesota and Anoka County require testing by a licensed, certified backflow assembly tester only.
Shutting off the preventer for winter Follow utility guidelines If properly instructed by your water utility, shutoff is permitted — but internal draining matters for freeze protection.
Identifying what type of preventer you have Safe to inspect and document Note the brand, model, and test cock positions for your service records — helps speed up testing.
Cleaning around the assembly Safe routine upkeep Keeping the area around the assembly clear of vegetation and debris prevents corrosion and aids annual testing.
