Back Water Valve



A Back Water Valve is often confused with a Backflow Preventer. However similar in purpose, a Back Water Valve is used in sanitary sewer applications whereas a Backflow Preventer is used to protect potable water.

The Back Water Valve (BWV) is designed to prevent sewage from reversing its intended flow. BWV’s are most commonly found in lift station systems to prevent the backflow of sewage during mechanical failures. However, their use is becoming increasingly popular in new homes.

Imagine the sewer main backing up and causing hundreds of gallons of sewage to back up into your home. Unfortunately, this is not as uncommon as it may seem.

There are many types of BWV’s available. Some may require more maintenance than others. Regardless, all require periodic maintenance which has led their undesirability. That aside, many homeowners would have rather dealt with the maintenance of a BWV opposed to the catastrophe they sustained.

Client Testimonials

Dana D

I contacted AAA Auger the first time because I had a gas leak below my island cooktop at home. They sent over a master plumber that same afternoon and the problem was fixed immediately and for an unexpectedly reasonable price. The second time I contacted them was because my water heater was leaking water all over the place in my office building, and he sent over another plumber within an hour of my call. He explained all my options to me so I could make a decision that was right for me and my company. They were so pleasant to work with both in my home and in my office, representing the highest ethics. AAA Auger also recommended an excellent water extractor and restoring service who took great care of us by giving me a very reasonable deal on his water extraction and carpet cleaning services, and he also installed a dehumidifier and a few blowers at very deep discount for us especially because we were referred by AAA Auger. The type of business relationships demonstrated by this really speak volumes about their integrity. We cannot thank AAA Auger and their affiliates enough for taking such great care of us within a matter of a few hours. Thanks to AAA Auger, what started out as a very unpleasant situation turned into a very positive one. And at the end of the day, I received a very polite phone call from his office ensuring my satisfaction. Their business operations are very well organized from start to finish, and his professional staff successfully carries out the processes to ensure that all his clients are happy at the end of the day. I will definitely do business again with AAA Auger for all my plumbing needs in the future, and I will confidently refer all my friends and clients to them for their plumbing needs as well.
