Comprehensive Backflow Testing, Installation, and Repair Services

Single Backflow Test

Ensuring your single backflow prevention assembly is functioning perfectly is critical to protecting your drinking water supply. Our certified backflow testers perform thorough inspections and testing of these devices, as each assembly is a mechanical device designed to stop reverse flow and protect potable water.

During testing, the tester also checks the test cocks as part of the inspection for accurate results, along with visual checks for wear and functionality.

We handle all documentation and compliance reporting to your local water provider, ensuring your plumbing system meets all regulatory requirements.

Commercial Backflow Testing

A commercial property often has complex plumbing systems with multiple backflow prevention mechanisms, including double-check valve assemblies and reduced pressure zone (RPZ) assemblies, and each site may have specific requirements based on its use and local rules.

These systems are subject to high pressure and frequent use, increasing the risk of backflow contamination. A cross connection is any connection between potable lines and non potable water sources that can create a backflow hazard and serious health risks for building occupants and the public water supply.

In some systems, downstream pressure can exceed supply pressure, increasing the risk of reverse flow into the public water supply. Our experienced team specializes in comprehensive commercial backflow testing, ensuring your prevention assemblies are properly maintained and compliant with local health codes.

Regular backflow testing helps avoid costly fines, water service interruptions, and protects the integrity of your irrigation systems and overall plumbing system.

Double Backflow Test

Properties equipped with dual backflow prevention assemblies require expert handling to ensure both devices are tested accurately and efficiently.

Our certified backflow testers conduct precise double backflow tests, verifying that both prevention assemblies and their internal valves maintain proper pressure and prevent reverse flow.

We submit all testing results to local authorities on your behalf, simplifying compliance and maintenance for your property.

Backflow Prevention Device Installation

Proper installation of backflow prevention assemblies and each backflow preventer is essential for effective backflow prevention and compliance with plumbing codes.

Our certified professionals install a range of backflow prevention devices, including air gaps, reduced pressure zone assemblies, and double-check valves, tailored to your property’s specific needs and installed at critical points in the water system where contamination risks are highest.

Proper installation and ongoing maintenance of these devices are crucial to safeguarding your drinking water supply from contamination risks and health hazards.

Fireline Backflow Testing

Fireline assemblies act as critical backflow prevention mechanisms within fire sprinkler systems, protecting potable water from contamination during firefighting activities and throughout the connected sprinkler system.

Sudden events like pipe bursts can also cause pressure changes that threaten the protected supply. These assemblies should be tested annually to keep their valves and relief mechanisms functioning correctly.

Hawthorne Plumbing, Heating & Cooling offers expert fireline backflow testing, using certified testers and specialized equipment to maintain your system’s safety and compliance.

Backflow Prevention Assembly Repair and Maintenance

Regular backflow testing often reveals worn or damaged components such as valves, springs, and seals within prevention assemblies before device failure occurs.

Our repair services restore your backflow prevention devices to factory specifications, and timely repair of a backflow preventer helps keep the assembly functioning correctly while protecting the drinking water supply.

Proper maintenance and timely repairs extend the lifespan of your prevention assemblies and help maintain compliance with local regulations.

Backflow Testing Frequently Asked Questions

What is backflow testing?

Backflow testing is a vital process that ensures water flows in only one direction within your plumbing system. This prevents contaminated water from reversing into the clean water supply, which could introduce harmful chemicals, bacteria, or pollutants.

The two main causes of backflow are back siphonage, which happens when negative pressure pulls water backward, and back-pressure.

The test involves checking backflow prevention devices like check valves and reduced pressure zone assemblies to confirm they function correctly under varying water pressure conditions. This testing protects your drinking water and complies with local water authority regulations.

Why is backflow testing necessary?

Backflow testing is essential for safeguarding public health by preventing contaminants from entering potable water supplies and creating health risks.

It ensures backflow prevention devices are working properly to stop hazardous substances from flowing backward due to pressure changes or cross connections.

Regular testing helps detect worn or damaged parts early, avoiding costly repairs and potential water contamination. Compliance with local water authority requirements also helps property owners avoid fines and service interruptions.

How often should backflow devices be tested?

Most states require annual backflow testing for backflow prevention devices, and many local water authorities do as well. Some jurisdictions, including Denver, mandate annual backflow testing for all properties.

This yearly testing ensures devices maintain proper water pressure control and prevent backflow effectively, and they should be tested annually. Some commercial or high-risk properties may need more frequent testing.

Annual tests help identify any issues like valve failures or leaks early, allowing timely repairs or replacement to maintain water safety and regulatory compliance.

What does the backflow testing process involve?

A certified backflow tester performs a detailed inspection of the backflow prevention device, including visual checks for damage or corrosion.

They test the internal valves and seals to ensure they hold water pressure correctly and prevent reverse flow, while the tester measures water pressure and checks for accurate results throughout the process.

The process involves monitoring water pressure before, during, and after testing, following strict testing protocols. A standard backflow test usually takes 30 minutes to one hour. Testers document results and submit compliance reports to the local water authority.

Who should perform backflow testing?

Backflow testing must be conducted by certified professionals trained in local testing protocols and standards.

These experts use specialized equipment to accurately assess device function and ensure compliance with regulations.

Certified testers can identify issues, perform minor repairs, and submit necessary documentation to local water authorities. Hiring qualified testers protects your water supply and helps avoid legal penalties.
