Backflow Prevention

Water Backflow Prevention in Concord, CA, and Surrounding Areas

Backflow is a reversal in the flow of water in a plumbing system caused by backpressure. Backflow can contaminate both the water supply and the main water line. Most residential and commercial buildings are required to have a backflow prevention system. So whether your backflow system needs to be tested, repaired, or replaced, just call on us.

The law requires business owners to have a backflow test at their premises by a certified plumber. If you are looking for a reputable plumber in Concord, CA, and the surrounding areas to perform backflow testing at your premises, rely on Absolute Plumbing and Drain. We have an expert team of certified plumbers who can undertake backflow testing professionally and with a smile.

The Process of Backflow Testing and Prevention

Backflow occurs when drinking water flows in reverse towards the source. Such water isn’t safe for drinking anymore, necessitating a backflow test. Backflow may result from an inordinately high demand at a water hydrant, which may contaminate the water source. Since you can’t be too sure when it would happen, or if it has already happened, a backflow test should be conducted by a certified plumbing company, offering professional plumbing services.

Before you conduct a backflow test, you need to obtain a letter from the authorities. If you already have this letter, contact us at Absolute Plumbing and Drain. Our expert plumbers have been in the field providing excellent plumbing repairs to clients in Concord, CA, and the surrounding areas for many years. You can trust them to test for backflow accurately and safely. They have no criminal record and have been tested for drug use before allowing them to work for us.  

The main aim of the backflow test is to determine whether backflow is present, and if so, what might be causing it. Our professional plumbers conduct the process by opening and closing the valves on the backflow testing device, looking out for any changes in gauge movement, leaks, or any other backflow sign. The process needs to ensure that the check valves can prevent backflow, airports can open when they should, and that relief valves when the pressure between the check valves is below 2 PSL and less than the pressure at the inlet device.

The Benefits of Backflow Testing and Prevention

The most obvious reason to get backflow testing and prevention at your property is to fulfill state law requirements. States require that all properties connected to public water have a backflow test conducted every year to prevent contamination of the water. If you don’t do it, you risk losing lots of money in fines. 

Backflow testing and prevention protect public water from possible contamination. Remember the water flowing back into the pipes isn’t safe for drinking, and if it gets back to the main supply, the entire city would face a serious health hazard. You don’t want to be the cause of such a huge problem because the ramifications would be too much to bear. It would taint your reputation, chase away your trusted clients, and plunge you into a costly lawsuit. Partner with us for affordable backflow testing and prevention in the following areas:
