COMMERCIAL BACKFLOW PROGRAM

Commercial Backflow Testing Made Simple

Testing, repairs, replacement and installation for commercial properties throughout Rockwall and the DFW area.

One call. Multiple properties. Backflow handled.

COMPLIANCE

Commercial Backflow Testing

Texas law (TCEQ Title 30, Chapter 290) requires annual testing of backflow prevention assemblies on commercial properties — fire suppression systems, irrigation connected to the municipal supply, and industrial water connections all qualify. Miss the deadline and your water provider can disconnect service at the meter, not just fine you.

We test every assembly type in use across DFW commercial properties: double check valves (DC), reduced pressure zone assemblies (RPZ), pressure vacuum breakers (PVB), and atmospheric vacuum breakers (AVB). After testing, we file the required report directly with your water provider — you don't manage the paperwork.

REPAIRS

Failed-Test Repairs & Replacement

A failed test means the assembly isn't providing adequate protection, and your water provider won't accept the compliance report until it's fixed. We carry the common repair parts and replacement assemblies for commercial-grade systems on our trucks, so most failures get repaired and re-tested in the same visit.

If a replacement requires a special-order part, we tell you the timeline immediately and document that the original failure was caught on the test date — so you have a paper trail showing you acted on schedule, not after the fact.

INSTALLATION

New Backflow Installation

New construction, remodels, and properties without an existing preventer all need a properly sized assembly installed to code before they can pass inspection or open for occupancy. We size and install DC, RPZ, and PVB assemblies for commercial applications and test immediately after install to establish your compliance baseline on day one.

This is also the right time to plan ahead: if you manage more than one property, we can standardize on assembly types and testing dates across your portfolio so future renewals line up on a single schedule instead of arriving on twelve different dates a year.

PORTFOLIO SERVICE

Multi-Property & Portfolio Service

Property managers and commercial owners with multiple locations don't need twelve separate plumbers or twelve separate compliance deadlines to track. One call schedules testing across your whole portfolio, and we track each property's renewal date so nothing lapses into a disconnection notice.

We've served Rockwall-area commercial properties since 1970 — offices, restaurants, retail, and multi-unit buildings. Backflow compliance for a portfolio works the same way: same team, same paperwork trail, same point of contact for every property.

Called at 10pm with a burst pipe. They were here in 30 minutes and had it fixed before midnight. Can't recommend enough.
