Backflow Repair

Your backflow preventer is one of the most important aspects of your building’s plumbing system. It is designed to prevent contaminated water, commonly from sprinkler systems from returning into your drinking water supply. In addition to irrigation, backflow preventers should be installed in swimming pools, dishwashers, washing machines, hose bibs and anywhere else where contaminated water is at risk of ending up in the clean water.

However, if your backflow preventer isn't working properly, you could be putting your drinking water at risk. The experts at All Pro Backflow, Inc. can test your backflow preventer to ensure it is in perfect working condition and if it isn't, we can do the necessary repairs to fix it. You may be asking yourself, "What is the risk? Why is backflow so critically dangerous?" Below we have provided just a few examples of the negative impact backflow has.

Why Is Backflow Dangerous?

Backflow, caused by cross-connections between clean and dirty water can contaminate your drinking potable water supply and lead to serious illness if consumed. In fact, over the past decade there have been countless reports of backflow that caused serious problems, including:

A cross-connection on an Alaskan crab processing ship resulted in backflow of sewage that became the culprit for 189 sick employees and a staggering loss of $35 million worth of processed crab.

In a San Antonio bar, carbonated water back-pressured into the potable water supply through faulty check valves on soda dispensing equipment, causing illness to many.

At a sports arena in Seattle, bright blue water flowed from drinking fountains. Several people reported general nausea.
