Backflow Testing Services in Paso Robles
Have you made an appointment to have your backflow prevention assembly inspected this year? Contact Rocksteady Plumbing at 805-237-7625 for certified backflow testing in Paso Robles, CA.
If you have a backflow prevention assembly installed on your property, annual testing is required to remain in compliance with county ordinances. Rocksteady Plumbing is a certified backflow testing company in San Luis Obispo County, serving customers in Paso Robles and surrounding areas.
In addition to testing, we can also help you install county-approved backflow prevention assemblies and repair your existing system. Give us a call to schedule immediate service in your area.
What is Backflow?
Backflow occurs when potable drinking water is mixed with contaminated water. The flow of water is reversed, causing the “backflow.” This is caused by either backpressure or backsiphonage.
Backpressure occurs when the water pressure in your plumbing line exceeds the water pressure of the municipal line. This allows wastewater from your plumbing system to enter the city’s main water line, which can lead to contaminated drinking water.
Backsiphonage occurs when contaminated water flows in the reverse direction due to a change in pressure. This often happens when a fire hydrant is in use or bursts, or when there is a water main break.
A properly installed backflow prevention assembly will help you avoid problems with backpressure and backsiphonage, and keep the community’s drinking water safe.
Are You Required to Install a Backflow Prevention Assembly?
Backflow prevention assemblies are mostly used in commercial buildings. However, some homeowners are required to have backflow prevention in place as well—particularly if you have cross connections between your plumbing system and the municipal water system.
If your property has any of the following, you will need to install a backflow prevention assembly per county regulations:
- Irrigation systems (sprinklers)
- Fire protection systems
- Large boilers (often used in multi-family buildings)
These systems can introduce harmful contaminants—such as pesticides, chemicals, chlorine, sediment, or waste—into the drinking water supply if cross-connection occurs.
Rocksteady Plumbing provides expert backflow prevention assembly installations for residential and commercial properties using Wilkins products.
The types of systems we install include:
- Lead-free reduced pressure principle assemblies (for domestic water lines)
- Double check detector assemblies (for fire protection systems)
- Double check assemblies
























Serving All of San Luis Obispo County
What to Expect During Backflow Testing
You will receive a reminder from the San Luis Obispo County Cross Connection Prevention Program forty-five days before your backflow test is due. Contact our certified backflow testers for timely service.
We will thoroughly inspect and test your backflow prevention assembly, making sure everything remains compliant with local code. If there are no problems, the process should take about 30 minutes. If we notice issues with your system (such as valve leaks or other irregularities), we will perform repairs on the spot. Once testing is complete, we will submit a test report to the city on your behalf.
Keep your drinking water clean and comply with local regulations
