Backflow Prevention in Murrieta & Temecula
What Is Backflow & Why Is It a Problem?
Backflow occurs when water flows in the opposite direction of its intended path, potentially carrying harmful chemicals, bacteria, or debris into your drinking water. This happens due to sudden changes in water pressure, often caused by events like broken water mains, high demand on municipal systems, or issues within your plumbing.
Without proper backflow prevention, contaminants from irrigation systems, industrial chemicals, or sewage can enter your home or business’s water supply. This poses significant health hazards and can lead to costly repairs or compliance violations.

Common Causes of Backflow
Backflow issues typically result from two main causes: back-siphonage and backpressure.
- Back-siphonage – Occurs when a sudden drop in water pressure causes water to reverse flow, pulling contaminants into your clean water lines. This can happen if a fire hydrant is opened suddenly or a major water main breaks.
- Backpressure – Happens when downstream pressure is greater than the supply pressure, forcing contaminated water into the clean water system. This can occur in commercial and industrial buildings where equipment uses pressurized water.
Other factors that can lead to backflow include:
-
- Cross-connections between potable and non-potable water sources
- Malfunctioning or missing backflow prevention devices
- Sudden drops in municipal water pressure
- Improperly installed sprinkler or irrigation systems
Regardless of the cause, backflow prevention devices are designed to stop contaminated water from entering your drinking supply, keeping your home or business safe.
Signs You May Have a Backflow Issue
Recognizing the early warning signs of backflow can help prevent serious water contamination issues.
Signs You Need To Schedule an Inspection:
Discolored Water
If your water appears brown, yellow, or cloudy, it could indicate contamination from rust, dirt, or chemicals entering your water supply.
Unpleasant Taste or Odor
A metallic, chlorine-like, or sulfuric smell and taste in your water could be a sign of pollutants entering your plumbing system.
Sudden Drops in Water Pressure
A significant and unexplained decrease in water pressure may indicate a backflow issue affecting your system.
Frequent Plumbing Issues
If you experience recurring plumbing problems, such as slow drainage or gurgling sounds, backflow may be a contributing factor.
If you notice any of these signs, don’t wait—backflow issues can escalate quickly, posing health risks and plumbing damage. Our experts can inspect, diagnose, and resolve the problem before it worsens.
