Backflow Preventers San Diego, CA

What Is Backflow?

Backflow – what is it and why is it so bad? Backflow is a plumbing term that describes the unwanted flow of water in the opposite, unintended direction.  If backflow occurs, potable or drinking water can become contaminated with wastewater.  Contaminated water may contain fertilizer/pesticides, human waste, chlorine from pools, and dirty water from sinks, dishwashers, and showers. Backflow can cause several issues by promoting corrosion of your pipes, creating leaks and create potential risks to your health.  Bill Howe Plumbing, Heating & Air, and Restoration & Flood can provide installation and testing services to ensure you and your family are protected. 

Backflow Prevention Devices

Backflow prevention devices can be installed in any number of places. There are different types of backflow preventers, but for commercial properties and newer residential properties, there is a larger backflow prevention device that prevents wastewater from the property from entering the city’s water supply.  These backflow prevention devices are required to be installed as close as possible to the water meter. This aids in eliminating the chances of an illegal connection being made between your meter and backflow device.  The City of San Diego also requires that backflow devices be tested at the time of installation, whenever the connection is moved and on an annual basis. A Bill Howe certified backflow tester can perform the annual testing as well as any maintenance that may need to occur. 

While these backflow prevention devices protect the municipal water supply from wastewater contaminants that may leave your property, there are plumbing codes and devices already within your property that are designed to help you with backflow protection.  Parts within toilets, faucets, sinks, and hoses have been created and regulated to keep you and your family safe from contamination. If you have an older home or dated plumbing fixtures, updating these fixtures is an affordable way to protect you and your family from contaminated wastewater.  A certified backflow technician can help update these fixtures to add an extra layer of protection from contaminated and dirty water.

Backflow Preventer Services

The costs associated with the installation backflow systems vary with each project.  A certified Bill Howe plumber can help determine which type of device is best for preventing backflow in your water and what those costs might be.  Call 1-800-BILL-HOWE to schedule an inspection and learn more about how Bill Howe can help you solve your backflow problems.

What David says about us

Service for new garbage disposal. My ancient garbage disposal quit working, went online to get Bill Howe’s number, immediately received and accepted chat to describe my needs. Prompt call back to schedule an appointment, service tech Allen was out same morning, which was important to fit my work schedule. Job estimate was clear, work done fully to my expectations, area left clean, and price was very fair.
I was not surprised — I have used Bill Howe plumbers for several other tasks in the past. I have always found their staff to be helpful, attentive, and the plumbers very courteous and capable.

What Mira says about us

Bill Howe never fails us! We had a drain overflow, and Scott came (on a Saturday) to look at it and offer solution. He was punctual, professional, and extremely helpful. I should also praise the main office for always being helpful and always finding solutions. Very grateful to have you in San Diego!

Restoration & Flood

What Ed Gohlich says about us

Cory was our technician on this job. We had a time sensitive repair issue and Bill Howe understood and assisted with getting the job done quickly.
Cory was on time to start the job and finished it quickly. Upon his leaving our home he’s was courteous, very knowledgeable, explaining what the problem was and how he fixed it. Very good communication and this is the way it’s has always been when we use Bill Howe plumbing.
Great company to work with.
Thanks Cory.

What Bridgett says about us

I am extremely happy with the service we received from Bill Howe Plumbing. We were given an incorrect diagnosis of our main sewer line from another vendor, but Bill Howe’s servicemen came out for a second opinion, correctly diagnosed our problem and resolved our back up issues. We will continue to use Bill Howe for all our future plumbing needs!

Thank you Bill Howe Plumbing.
