What Is Backflow?

In your home’s or commercial building’s water-supply infrastructure, your water should stay at a constant pressure. This is essential to ensure that stagnant water does not infiltrate your system and that the dirty sewage water stays in its designated storage area.

Sometimes, however, this pressure can fluctuate, causing the contaminated water to seep its way into your supply of drinking water. Backflow has two leading causes:

  • Back pressure

Back pressure occurs when the contaminated water gets pushed back into your clean water supply. Either mechanical means or thermal expansion, caused by a spoiled water heater or boiler, can contribute to back pressure.

  • Back Siphonage

Back siphonage occurs when the contaminated water gets sucked into your property’s water system. Back siphonage happens as a result of pressure changes or device malfunctions.

Though sewer backups are the more common problems associated with backflow, the real dangers lie in the type of bacteria, chemicals, and pollutants that could contaminate your water supply.

Sewer water could contain bacteria such as leptospirosis and Heliobacter Pylori that cause muscle aches and ulcers, respectively. Acanthamoeba could also contaminate your water, causing nose, throat, eye, and ear infections.

Other common culprits might be insecticides and chemicals like sodium hydroxide that could cause various health complications such as respiratory issues.

The Importance of Backflow Device Testing

A backflow device, sometimes known as an RPZ valve, is a device you install on your plumbing system, to protect your water from contamination. In the event of a decrease in water pressure, your backflow device will open and dump out the water, preventing the contaminated water from backflowing into your water supply.

While backflow devices have a lifespan of up to 40 years, they consist of nuts, bolts, springs, and screws that are prone to malfunction. When one part breaks down, your entire backflow device might fail, leaving your water supply vulnerable.

Usually, backflow devices come with two safety-check valves. The first valve only opens when the water pressure reaches a specific level. The second safety-check valve is responsible for preventing backflow caused by back pressure. Regardless of the type of failure, it will impair the device’s performance.

The common wear and tear and potential malfunctions are why backflow device testing is crucial. The test allows our qualified and licensed technicians to check your device for any signs of damage, offering repair services early on to prevent the device from completely failing.

Once our technician tests your backflow device and ensures its proper operation, we provide you with the certified paperwork. Having backflow device testing annually ensures that your water supply stays backflow-free and safe for you and your family to drink.

Staying local made sure that I was taken care of once again. Called on a Thursday and they had someone out by 8am on Friday. Al did a phenomenal job! I explained the issues, he gave me 4 different solution options with pricing, answered all my questions, kept everything clean and sanitary, and was so kind. Job was completed the same day and was reasonably priced. As a single female I didn't feel like I was manipulated for extra services or overpriced, I was treated with complete respect. I'll certainly use them again!

The whole process was very easy. From making the appointment online and the confirmation via text message, they sent me a photo of the plumber who was going to come to my house. The day of the appointment the plumber called me to tell me that he was on his way. Upon arrival at the house he was very professional and courteous. He explained everything to me in great detail. I recommend this company 100% and they accept all kinds of payments plus a guarantee on the job for one year.

Sam came out for the estimate and recorded everything they were going to do along with taking photos. Job was redoing feed and drain lines under the sink, and installing a new dishwasher and disposal. Called on Monday to schedule once the dishwasher was delivered, and they had us booked for the next day. Al showed up on time for appointment, completed all work quickly, leak checked, ran washer and disposal to verify correct operation, took photos to document, and packed out all the debris. Under $900 parts and labor, including new cutoff valves, new washer feed line, new sink trap, removal and reinstall of disposal and dishwasher, including supplies. Charged exactly what was provided on the job estimate. Highly recommended.

I absolutely recommend Prime Plumbing. I called them after seeing positive Google reviews. The office agent got an appointment 3 hours after I called. The technician called me 5-10 minutes before arrival. Will, the technician was super professional and thoughtful about the space. He wore the disposable shoe protectors as to not bring the outdoors inside. He was mindful not to use machinery that would harm my home. He also answered my questions with a friendly and pleasant demeanor. The problem was fixed and I was so happy. 5 stars!

Amara B.

A real person answered the phone at 4:30 pm and not a long voicemail. It was easy to schedule an appointment. Information regarding upfront consultation fee was provided during the phone call. Reminder text message was sent one day before the appointment. On the day of the appointment, an additional text message with the picture of the plumber who is coming was sent. Overall a very pleasant experience. Our plumber was knowledgeable and professional. He also made sure to put on booties which I really appreciated
