You’ll understand what’s required and why. We walk you through test results, compliance needs, and next steps so you can move forward confidently.

Backflow Repair Services

Backflow preventers can fail due to wear, mineral buildup, or mechanical problems.

Even minor malfunctions can compromise your water supply and cause code violations. GEM technicians provide reliable repairs to restore safe operation. Call us if you have:

Fluctuating or low water pressure can signal a failing backflow device and affect overall plumbing performance. Our team will identify the cause and restore steady flow while ensuring the system is properly protected.

Leaks around a backflow preventer often point to worn seals, corrosion, or loose connections that can compromise water safety. We repair or replace damaged components to create a secure, code-compliant seal.

A valve that sticks or doesn’t close properly can allow water to reverse direction and create contamination risks. Our fully licensed plumbers will test valve operation, replace worn parts, and confirm reliable performance.

Air trapped inside your assembly can disrupt flow and reduce system performance. We remove trapped air, inspect the system, and restore consistent water movement.

Backflow Replacement Services

Some assemblies are too old or damaged to repair safely.

GEM replaces outdated backflow preventers with modern, code-compliant devices. Our technicians remove the old assembly, install the correct device for your plumbing system, and test it thoroughly for compliance and safety. Signs you may need a backflow replacement include:

Older backflow devices lose reliability over time and may no longer meet current code requirements. Replacing an aging assembly improves long-term performance and reduces the risk of unexpected failures.

If a backflow device needs repairs multiple times a year, it can become costly and disruptive. Replacing the unit helps eliminate ongoing repair expenses and provides more consistent, reliable protection.

A device that fails testing or does not fully prevent backflow puts your water supply at risk. Installing a new assembly ensures proper operation and helps maintain safe, compliant water flow.

Exposure to water, weather, or chemicals can damage internal components and compromise performance. Replacing a corroded or damaged device restores proper function and helps prevent leaks or contamination.

Your backflow preventer works silently every day to keep your water supply safe.

Regular maintenance and annual testing ensure it continues to operate correctly, protects your home or business, and keeps you in compliance with local regulations. When a GEM technician comes to your property for backflow maintenance or testing, you can expect us to:

Our team examines the backflow assembly for signs of corrosion, cracks, or worn components. Identifying damage early helps prevent failures and maintain reliable system performance.

We check valves and internal parts to ensure they open and close properly under normal conditions. This helps confirm your device is functioning as intended and protecting your water supply.

Certified testing is completed to verify your assembly meets local safety and compliance standards. Results are documented to support inspections and regulatory requirements.

We confirm your device is installed correctly and has the proper spacing for safe operation and servicing. Proper placement supports performance and ensures the system meets current code requirements.
