Why Backflow Prevention Matters
Backflow occurs when contaminated water is drawn back into your clean water supply due to changes in water pressure or cross-connections. Left unchecked, backflow can contaminate drinking water, create health hazards, and expose property owners to regulatory fines. Municipalities and state agencies require regular testing and reliable maintenance of backflow prevention devices to protect public health and comply with regulations. Professional inspection and servicing ensure your system functions correctly when it matters most.

How Our Services Work
01
Initial Assessment and Scheduling
We begin with a phone or online consultation. For new clients, we review system history and schedule an on-site inspection that aligns with your municipal testing calendar or immediate needs.
02
Certified Backflow Testing
Our state-certified inspector performs step-by-step testing of your backflow prevention device(s), using calibrated gauges and industry-standard methods. We document test results and provide the official paperwork required by local authorities.
03
Diagnostics and Repair
If testing indicates failure or deterioration, our technicians diagnose the issue, explain repair options, and provide a no-surprise estimate. Typical repairs include valve adjustments, seat replacements, springs, and minor parts.
04
Replacement and Installation
When repairs are not feasible, we present replacement options tailored to your system type, water pressure, and budget. We install and commission new backflow assemblies and ensure proper tagging and registration.
05
Maintenance and Annual Testing
We offer scheduled maintenance plans and annual testing reminders to keep your system compliant and functional year after year.
Why Professional Testing and Maintenance Matters
Backflow devices experience wear, mineral buildup, spring fatigue, and occasional mechanical failure. Proper testing and ongoing maintenance protect your family, employees, and customers from contaminated water. Municipalities typically require annual testing; failure to comply can lead to fines or service interruptions. Our work ensures safety, compliance, and peace of mind.
Common Signs You Need Service
- Sudden drop or spike in water pressure
- Discolored, smelly, or odd-tasting water
- Plumbing fixtures backing up
- Failed municipal test notices or expired test certificate
- Visible leaks or damaged test cocks and housings
Residential and Commercial Service Differences
Residential systems are smaller and often easier to access, but they still require precise testing and occasional parts replacement. Commercial systems tend to be more complex (double-check valves, reduced pressure zone assemblies, pressure vacuum breakers), require more detailed documentation, and sometimes must be serviced during off-hours to minimize operational impact. We plan accordingly and coordinate with building managers to reduce disruption.
