Are You at Risk for Backflow Contamination?

When considering the risk of backflow contamination, the areas of concern include anywhere that water may be pooled around an outdoor faucet or fixture, such as pesticide–laden water existing around a sprinkler heat, a sink hose submerged in a pool of soapy water, or a supply pipe that may contain chemicals that leads into an indoor plumbing system. Irrigation systems also increase your risk of backflow contamination.

The majority of commercial spaces are required to have backflow devices installed and to have testing done on a routine basis. The installation and service of these devices are regulated by local authorities, and if you do need a device such as this, it is vital that you contact a plumber with backflow certification.

Hiring a Backflow–Certified Plumber

Have you recently found out that you need a backflow prevention device installed on your property, or do you need backflow testing and repairs done? Then you need a professional plumber with the right certification. Our team is highly trained and certified to complete these types of jobs safely and effectively.

You want your system to function reliably, and you want to ensure that you are in compliance with local regulations. Since 2009, our staff has proven to be extremely competent in plumbing services of all kinds, including backflow prevention services.

How Does Backflow Testing Work?

Within some plumbing systems, there already exists an air gap used to prevent backflow from occurring. This consists of an open vertical space within the system that prevents cross-contamination. However, in locations where there is even a small risk of backflow entering supply pipes, a backflow preventer needs to be installed.

In order to ensure it properly works, however, it needs to be tested on a regular basis. One of our expertly trained technicians can connect a test kit to the backflow prevention device and verify that it is functioning as it should. This service requires that all water downstream of the backflow device be shut off to perform the test. If you have any questions about this process, please don’t hesitate to give our team a call!

Sweetwater is an honest and excellent worker. Had a leak in my bathroom from the tub spout. He told me exactly what had to be done before The leak could be fixed. I took care of that and within 2 days he came back out and finished the job. Price was fair and he is very reliable.

Had an issue where our kitchen sink was getting no cold water. Dakota came out quickly after our call and fixed our problem so fast! He found a screw in the shut off valve that had probably fallen in there during our remodel done 2 years ago. I was so happy Dakota solved our problem! He was great! Highly recommend.

This was the third time we've used them. And it was as good as the first time.
Angel Corrales
I had a problem with the sink water building up and not draining. After trying to unclog it I called Sweetwater Plumbing and they sent technician Victor out to assess the issue. I explained to Victor the issue and he knew what to do right away. After running the snake he cleared the stoppage and it drains just fine now.
