Hydro Jetting Services
Hydro Jetting Services in Marin, Sonoma & Napa County
Your sewer line may be out of sight, but it should never be out of mind, especially when plumbing problems start affecting your home. Common signs of a blocked sewer line include:
- Bubbling water in your toilet.
- Wastewater backing up into your shower or bathtub when you flush.
- Slow-draining sinks, tubs, or showers.
- Persistent sewer odors or gurgling sounds from your drains.
If you’re experiencing any of these issues, our team at Ongaro & Sons can help. We’ll determine whether the problem is isolated to a single drain or if it involves a deeper blockage in your main sewer line. When a sewer line is clogged, immediate action is essential to prevent messy and costly wastewater backups. In many cases, we recommend hydro jetting, a powerful, non-invasive method that clears debris and buildup to restore full flow.
Ongaro & Sons proudly serves homeowners throughout the North Bay, including Marin, Sonoma, and Napa counties. Whether you’re dealing with a clogged drain, sewer line blockage, or another plumbing concern, our expert team is ready to help. Call us today for a free consultation and experience the trusted service that local families have counted on since 1932.
All work is performed under active California contractors license #215233.
What Is Hydro Jetting?
Hydro jetting is similar to power washing, but in your drain and sewer pipes. The process uses 2,000 to 4,000 psi of water pressure to flush out grease, tree roots, sludge, and other matter accumulated in your sewer pipe. Our experienced Ongaro & Sons plumbers inspect your sewer line before initiating hydro jetting to determine if it is structurally sound.
If your sewer pipe is unlikely to withstand hydro jetting because of its age and structure, we are happy to discuss other sewer cleaning options, such as snaking. This alternative breaks up clogs but does not scour the pipe walls. It is safer for a weakened sewer line because it does not use high pressure. If this is the case, we are also happy to provide you with a quote for sewer line replacement.
Initial Video Inspection
We begin with a video pipe inspection to locate the blockage and assess the condition of your sewer line. This step helps us determine the severity of the clog and how much water pressure is appropriate for the job.
Assessing Pipe Condition
The inspection also shows whether your pipe is a good candidate for hydro jetting. If your sewer line is too deteriorated to safely handle high-pressure cleaning, we’ll recommend an alternative solution to avoid further damage.
Hydro Jetting Setup and Execution
If hydro jetting is appropriate, we insert a specialized hose into your sewer cleanout. Our equipment then delivers powerful blasts of water to clear away buildup, grease, roots, and other debris from inside your sewer pipe.
Post-Cleaning Video Inspection
After jetting, we perform a second video inspection to ensure the clog is fully removed and your pipe is clear. This final look helps confirm our work meets both your expectations and our high-quality standards.
Customer Satisfaction Guaranteed
Your satisfaction is our priority. We review the results with you and answer any questions. We don’t consider the job done until you’re completely happy with the service and your sewer line is flowing freely.
Hydro Jetting as a Maintenance Tool
Your sewer line is just one of many plumbing system components that benefit from preventative maintenance. We recommend hydro jetting every two to three years in homes. This periodic hydro jetting can help keep your sewer line in top condition by removing grease, organic material, silt, tree roots, and other debris. Maintaining this essential drainage pipe with hydro jetting will help avoid future plumbing emergencies.

Why Ongaro & Sons for Hydro Jetting
Jetting is powerful, which is exactly why it should not be the default answer.
Schedule Service →Line condition checked before jetting
High pressure in a line that is already failing can cause real damage. A camera survey first is what makes jetting safe.
Correct for grease and roots specifically
Where the blockage is grease build-up or root mass, jetting cleans the full pipe wall in a way cabling cannot.
Nozzle and pressure matched to the pipe
Material and diameter decide the setup. One configuration for every job is how lines get damaged.
Verified afterwards on camera
You get to see that the line is actually clear rather than take it on trust.
We will decline it where it would do damage
On a fragile or already failing line, jetting is the wrong tool. Saying so costs us the job and saves you a collapse.
