Testing & Certification

Our certified technicians carefully evaluate every component of your assembly to verify it's functioning properly and meets local certification standards. We handle the test, the compliance paperwork, and the submittal to your water authority — so you stay compliant without lifting a finger.

02We Build These In-House

Anti-Theft Cages & Protection

With copper and brass prices at record highs, exposed backflow assemblies are prime targets — and a theft means costly replacement, lost water service, and compliance headaches. We design, build, and install custom steel enclosures and cages that lock your assembly down before it becomes a statistic.

Custom-fabricated to fit any assembly size or location
Heavy-gauge steel, powder-coated, locking access
Poured concrete pads for a permanent, tamper-resistant install
03Failed a Test? We Fix It.

Repair & Replacement

Any assembly, any make, any size, any time. Every service truck rolls out fully stocked with a comprehensive backflow parts inventory, so we can diagnose and complete most repairs on the spot — then re-certify. Less downtime, faster compliance, a system you can count on.

If we perform the repair, the post-repair certification is included — no separate fee.
