Backflow Prevention Repair & Service in Atlanta Metro

Received a Failed Test Notice or Spotting Leaks?

Is your water suddenly discolored or foul-smelling, or did you just get that dreaded notice from the utility company about a failed backflow test? These aren't minor inconveniences; they are direct warnings that your home's clean water supply is at risk of contamination. Head's Plumbing Sales and Service, Inc. has certified technicians ready across the Atlanta Metro to diagnose and repair your backflow preventer correctly.

Warning Signs Your Backflow Preventer Needs Repair

Discolored or Foul-Smelling Water

When the water from your tap is cloudy, brown, or has a chemical or sewage-like odor, it’s a serious red flag. This indicates that your backflow preventer has failed, allowing contaminated water from your irrigation system or other non-potable sources to siphon back into your drinking water. This is a health hazard that requires immediate professional attention to protect your family.

Sudden Drop in Water Pressure

If your showers feel weak or faucets trickle, especially after using an outdoor spigot, it could be your backflow device. An internal failure, like a stuck check valve or a ruptured diaphragm, can create a bottleneck in your main water line, restricting flow to the entire house. While annoying, this pressure drop is a symptom of a mechanical failure that compromises your water safety.

Visible Leaks or Constant Dripping

Seeing water pooling around the outdoor assembly or hearing a constant drip or hiss is a clear sign of a problem. Leaks often mean a cracked casing from a freeze, a worn-out seal, or a relief valve that's stuck open due to an internal pressure imbalance. A device that can't hold water can't be trusted to prevent backflow, and the problem will only get worse.

Failed Annual Backflow Test

Receiving a failure notice from your water authority is the most definitive sign of a problem. During a certified test, a technician uses calibrated gauges to confirm the internal check valves and relief valve are operating within precise specifications. A failure means the device is no longer providing reliable protection and your water supply is vulnerable.

Common Causes of Backflow Preventer Failure in the Atlanta Metro

Age and General Wear

Like any mechanical device, your backflow preventer has moving parts—springs, rubber seals, and check valves—that wear out over time. After years of constant pressure and water flow, these components degrade, lose their tension, and fail to create a proper seal. This is the most common reason we see for repairs on older devices.

Freeze Damage

Even a brief but hard Atlanta Metro freeze can be enough to crack the brass body or rupture the internal components of an unprotected backflow preventer. When water trapped inside the assembly freezes, it expands with enough force to cause catastrophic damage. This kind of failure is often severe and requires significant component replacement or a full device change-out.

Debris and Mineral Buildup

Small particles of sediment, rust, or sand in the water supply can get lodged in the delicate sealing surfaces of the check valves, preventing them from closing completely. Over time, mineral scale from hard water can also build up, causing moving parts to stick and fail. This is why we often have to fully disassemble and clean a device during a repair service.

Water Pressure Spikes and Water Hammer

Sudden, sharp changes in water pressure can slam internal components around, causing premature wear and damage. This "water hammer" effect, often heard as a banging in the pipes, sends a shockwave through the system that is especially hard on the springs and diaphragms inside your backflow preventer. Consistent pressure spikes will eventually lead to a component failure.

What to Expect During Your Backflow Repair Service

When you call us for a backflow issue, we send a certified technician who knows these devices inside and out. We don't guess; we start by listening to what you've observed and then perform a full diagnostic inspection of the assembly. This includes a visual check for obvious damage and a formal test with calibrated equipment to pinpoint exactly which internal component has failed.

Once we’ve identified the root cause, we’ll walk you through the problem, showing you the faulty parts and explaining your options clearly. We’ll provide a straightforward, upfront price for either rebuilding the device with a manufacturer-approved repair kit or, if the damage is too severe, replacing the entire unit. We carry common repair kits on our trucks, so many repairs can be completed in a single visit.

After the repair is done, we don't just pack up and leave. We perform another full diagnostic test to certify that the device is operating correctly and protecting your water supply according to code. We’ll provide you with the official passing test report for your records and for the water authority, ensuring you are fully compliant and, more importantly, that your family’s water is safe.
