As a small family-operated company, we stay personally connected to our customers and the work we perform.
Why Backflow Prevention Matters
Your plumbing system is designed to keep potable water moving in the proper direction. Under certain pressure conditions, however, water can potentially reverse direction. This is known as backflow.
A backflow prevention device is designed to help stop that reverse movement and protect the potable water supply from unwanted substances. Testing helps determine whether the device can perform its intended function when needed.
When Should a Backflow Preventer Be Tested?
Testing needs can vary depending on the property, plumbing system, type of device, and applicable local requirements.
Backflow testing may be appropriate when:
- Your property has an existing backflow prevention device
- Testing has been requested for the property
- You need to confirm that a device is functioning properly
- A previous test identified a concern
- Plumbing changes may affect the existing setup
- You’re unsure about the condition of the device
- To keep your commercial site compliant, annual testing is required
If you’re uncertain about what applies to your property, we can help you determine the appropriate next step.
What Happens During Backflow Testing?
Backflow testing is focused on checking the performance of the prevention device. Our team evaluates the device using appropriate testing equipment and looks for indications that it may not be operating as intended.
Once testing is complete, we’ll explain the results clearly. If an issue is identified, we can discuss what may need attention so you understand your options before moving forward.
Our goal is to make a technical plumbing service straightforward and easy to understand.
