If you have a sprinkler system, there is one question you should ask yourself: do I need a backflow preventer? The answer is yes!

A backflow preventer helps keep your water clean and safe by preventing dirty water or chemicals from flowing back into the water supply.

It’s especially important in areas where drought is common, as they help conserve water by preventing contamination and runoff.

In this blog post, we’ll discuss why installing a backflow preventer is essential to keeping your sprinkler system running smoothly and safely.

What Is a Backflow Preventer?

A backflow preventer is a device that prevents contaminated water from seeping into the public drinking water supply through your sprinkler system.

It works by blocking any reverse flow of liquid between two different sources of pressure—such as an irrigation system and the municipal drinking water supply—so that only clean drinking water flows back into your home.

Why You Need It

Backflow preventers are becoming increasingly important as droughts become more frequent and severe in many parts of the world. Without one, your sprinkler system could be subject to contamination from sewage or other chemicals which could cause serious health problems for anyone using it.

Additionally, without a backflow preventer in place, you may be wasting precious resources due to runoff from your sprinkler system which can lead to costly fines or even legal action from local authorities.

Therefore, it’s essential to install one if you want to protect both yourself and the environment.

The Benefits of Installing a Backflow Preventer

Having a backflow preventer installed in your sprinkler system brings several benefits to your home or business.

For starters, it helps protect both humans and animals from hazardous materials entering their drinking water supply.

Secondly, it also helps reduce the amount of waste that goes into waterways.

Finally, it helps conserve water by reducing evaporation, which can be beneficial during times of drought or other natural disasters.

Installing a Backflow Preventer

Fortunately, installing a backflow preventer isn’t too difficult—it just requires some help from an experienced plumber who knows how to properly attach it to your existing irrigation system.

Once it’s installed, you can rest assured knowing that your sprinkler system will be running smoothly and safely with no risk of contamination or runoff.


In summary, if you have an irrigation system then you should strongly consider installing a backflow preventer for both safety reasons and environmental conservation reasons.

A good plumber can help you install one quickly and easily so that you can rest assured knowing that your sprinkler system is running smoothly and safely with no risk of contamination or runoff—which saves both time and money in the long run!
