Backflow prevention assemblies are the unsung guardians of our public water supply. Required by SAWS, TCEQ, and local codes, these devices prevent contaminated water from your irrigation or commercial system from flowing back into the clean city water supply.

Merritt Plumbing is certified to test, repair, and install all types of backflow preventers (RPZ, DCVA, PVB) for commercial, industrial, and irrigation systems.

We Handle the Paperwork:

• Annual Testing: We perform the required gauge test to ensure the assembly is functioning correctly.
• Reporting: We submit the official test report directly to SAWS (or your local water purveyor) on your behalf, so you stay compliant and avoid fines.
• Tagging: We tag the device with the current certification date.
  
  

Repair & Installation:

• Diagnostics: If a device fails, we diagnose the cause (fouled checks, relief valve failure).
• Rebuilds: We stock repair kits to fix many assemblies on the spot.
• Replacement: If a unit is beyond repair or stolen (a common issue), we install a new, code-compliant assembly with theft-deterrent cages if needed.
