How to Prevent Backflow Contamination at Your Home or Business

Whether you get your water from a private well system or from a municipal system, it’s important that it’s not contaminated. Strict state guidelines and water filtration systems reduce the risk of bacteria and other substances from getting into your water. However, there are a few instances that could lead to contamination of your home’s drinking water.

In this post, we take a closer look at what those instances might be and how backflow prevention devices protect against contamination.

What Is Backflow?

Simply put, backflow is the reversal of the flow of water. This becomes a problem when waste water reverses and comes into contact with clean water or vice versa. It’s problem that commercial properties must be aware of at all times, but it’s something that happens to residential properties too.

Why Does Backflow Happen?

There are a number of situations that lead to backflow problems. These include the following:

  • Backpressure – Pressure that causes the reverse flow of water.
  • Backsiphonage – Happens when there is a type of vacuum or negative pressure in your water supply system.
  • Worn parts – Old or worn parts can lose their effectiveness over time. This can lead to problems with backflow.
  • A broken water main – When a water main breaks it can affect water pressure and cause backflow to occur.
  • Weak water pressure
  • Irrigation system issues

In all instances where there is a change in water pressure, you are at risk for backflow and water contamination. For example, a leak or crack in your pipes can cause water pressure to change and weaken.

As you can see, these aren’t problems that only affect commercial plumbing.

What Can You Do to Prevent a Problem

Replacing old, worn out parts of your plumbing system and staying on top of water pressure issues is important. Also, if you have a sprinkler system, have it checked before using it each year to make sure there aren’t any problems.

Aside from regular plumbing inspections, the best way to prevent backflow is to install a backflow preventer. This is a required device by most municipalities for commercial properties, but residential property owners benefit from the installation of this device too.

A preventer device automatically stops water from flowing in a backward direction.

Backflow Preventer Testing

Keep in mind that installing a backflow preventer device isn’t enough. You also need to make sure it’s always working. Schedule testing once a year from a plumber certified in backflow prevention to test the device and make any adjustments necessary.
