Complete Backflow Protection in San Marcos
When a drop in municipal pressure allows non‑potable water from irrigation, pools, or fire systems to reverse flow into your home lines, the results can be hazardous. In San Marcos—where river flooding and seasonal demand swings are common—a reliable backflow assembly is essential.
Anchor Plumbing Services installs and configures reduced‑pressure zone (RPZ) and double‑check valve assemblies tailored to your property’s layout and hazard level. We select the correct model, position it for optimal performance, and integrate it seamlessly into your existing plumbing.
Beyond installation, we conduct the state‑required annual tests using calibrated gauges. We verify valve integrity, record differential pressures, and provide complete test reports and certification for your records and municipal compliance. If equipment fails, we offer prompt repair or replacement to restore full protection.

Why San Marcos Needs Backflow Prevention
San Marcos homes often connect to the Edwards Aquifer via irrigation systems, boilers, and fire lines. Sudden pressure losses—during firefighting or water main breaks—can siphon river or stormwater back into potable lines.
Without proper assemblies, fertilizers, pesticides, and biological contaminants pose severe health risks. Routine testing and maintenance ensure your backflow preventers respond instantly, safeguarding every tap from cross‑connection hazards.

Quick Answer To Questions you may have
What is backflow and why is it dangerous?
Backflow reverses water flow, allowing irrigation or pool water containing chemicals and bacteria to enter your potable supply, risking serious health hazards.
How often must backflow assemblies be tested?
Local and TCEQ regulations require annual testing of RPZ and double‑check valve assemblies to verify they prevent reverse flow correctly.
Which assembly is right for my San Marcos property?
RPZ assemblies suit high‑hazard connections like chemical injectors or pool returns, while double‑check valves protect lower‑risk systems such as landscape irrigation.
Do you handle permits and reporting?
Yes. We manage all water‑authority permits, schedule inspections, and submit compliance certificates on your behalf for a worry‑free process.
What happens if my test fails?
We diagnose the issue—repairing or replacing faulty components—and retest at no extra cost until your assembly passes and you receive official certification.
