Backflow can happen two different ways:
1. Backpressure – this happens due to elevations within piping systems, various pumps, or caused from expansion due to heat.

2. Backsiphonage – mostly due to pressure loss within our water drinking system from a breakage in a water main or the pipe supply near by.


Of course this may sound foreign and we understand that. Simply, it is the unwanted return of fluids, chemicals or any other foreign material into our public drinking water system due to a loss of pressure in the lines supplying your water or an increase in pressure from your water system to the supply line. The water we are trying to protect may be the water you drink at work from an ice machine, your water at home from the refrigerator, your drink at the restaurant you love to eat at, or the water your family members are being supplied while in the hospital. As part of human nature, we do not want our drinking water contaminated, polluted or poor quality and purity. If our drinking water were to become contaminated, our health may be at serious risk. We, Mr. Backflow, LLC., take this very seriously, not only for our customers health, but our own.


To keep our water from becoming contaminated with undesirable substances, mechanical backflow prevention assemblies are installed to protect the water supply. A certified tester is required to test them annually or as instructed by manufacturer/city & state requirements.


A common tip for homeowners: garden hoses should never be submerged in or attached to a non-potable substance, this can be an easy way for water cross contamination to occur and a simple prevention tool. We hope that this bit of information will help you understand the importance and meaningfulness of why we test your backflow assemblies.

What is Backflow?

Backflow testing


Backflows for most cities are needed to be tested annually, although some cities require them to be tested more frequently and others to only be tested upon installation. Most cities send out letters when it is time to get your backflow to be tested, and we do our best to inform our customers around the same time to help remind you. We are certified to test backflows on any type of system including domestic water lines, irrigation and fireline backflows.  Although backflows pass the majority of the time, the do not pass every time. When a backflow fails it is generally not of great concern because as time goes on the internal parts just need to be repaired.


Backflow repair


When a backflow begins to not work properly anymore, in most cases it is as simple as just repairing the internal parts of the backflow. This is important to remember because as we have been working in the backflow field, time after time we have heard of plumbers saying the backflow needs to be replaced. This is not the case the majority of the time and is much less costly to be repaired than replaced. Replacing backflows requires permits from the city, bringing the backflow up to code (if the code has changed), and possibly replacing some plumbing that could also be out of code. We are capable to repair the majority of the different types of backflows and in most cases are able to bring the backflow back to working like new again.


Backflow Replacement


In the case that a backflow either cannot be repaired, too costly to repair, or parts are no longer available to repair the backflow, we are also licensed to replace all the various types of backflows. When we replace backflow preventers we do our best to install a more reliable and higher quality device to avoid the issues of the previous device. We do know that backflows are confusing, but we are more than willing to explain, or answer any questions you have about backflow.
