Backflow Prevention Services

Backflow Prevention Services in Covina

Call the Team from Courtesy Plumbing Today

Every business and even some homes are required to have backflow prevention devices in order to prevent used or potentially contaminated water from reaching the potable water supply. This can be a serious issue both for your home as a whole and for the public water supply, as even a small amount of contamination can have detrimental consequences. A backflow prevention device’s job is to prevent this from happening by shutting off the flow of water in the reverse direction, thus keeping your plumbing system contained and protected.

Is your backflow prevention device working properly? When was the last time you had it inspected? If you need a repair or inspection service, Courtesy Plumbing can come to you and get it done so your building remains protected. Our mission is in our name: provide you with professional-quality plumbing services from a team of friendly and courteous plumbers. When you demand the best for your home, we make it our mission to deliver nothing short of that—from the time we arrive until we’re done with the job, we want you to be completely satisfied with the service you receive. We even make sure to offer our services with minimal down time to your home or business so the process is as quick as possible.

When you need your backflow prevention device serviced, call Courtesy Plumbing at (626) 774-7167 and schedule your inspection, repair, or replacement today.

Backflow Prevention Inspection

Our Covina backflow prevention inspection team can conduct a thorough examination of your backflow prevention hardware, ensuring it’s working properly, performs within accepted parameters, and will continue to work properly for the next year. All business are required to have a backflow prevention device as well as multi-family residential buildings, but some homes have them as well depending on the plumbing that’s installed.

We test backflow prevention devices for each of the following:

  • Office complexes
  • Condos & apartment buildings
  • Restaurants
  • Hotels
  • Industrial buildings

California law requires that all backflow prevention devices be tested at least once a year in order to verify that they are working correctly and no further maintenance is needed. We can not only provide this inspection, but can even help you with maintenance, repair, and replacement services if your backflow prevention device needs additional attention or care. We’ve proudly offered a full range of plumbing services to our community for years, and pay special attention to ensure your system works properly and your local water supply remains completely protected.
