Hydro jetting uses a high-pressure stream of water to scour the inside of a drain or sewer line. It clears grease, sludge, scale, and soft buildup that can stay on the pipe walls after a basic clog is cleared.
If a drain keeps clogging, or several fixtures run slow at once, hydro jetting is often worth considering. It is also used when a line needs a deeper clean after repeated backups.
North Hollywood Plumbing Company provides hydro jetting for homes, apartments, restaurants, offices, and other properties in North Hollywood and the San Fernando Valley. We look inside the pipe first, because jetting is only the right choice when the line can handle it.
Every job starts with what is happening inside the pipe. Here is how we approach it.

We ask which fixtures are affected, when the problem started, and whether the line has been cleared before. Then we run a sewer camera through the line, where access allows, before any jetting begins.
The camera shows pipe material, roots, buildup, offsets, cracks, and standing water. If the pipe looks too damaged to jet, we tell you and talk through other options.

We locate the cleanout or access point and protect the area around it. Pressure and nozzle choice are matched to the pipe's material and condition and to the kind of buildup we find.
A cutting nozzle for roots is not the same tool as a flushing nozzle for grease.

The hose and nozzle move through the pipe, scouring the walls and pushing debris toward the sewer. Heavy buildup may take more than one pass.

After jetting, we send the camera back through to confirm the line is clear and to see whether buildup was hiding damage. We clean up the work area and explain what we found.
This clears the line that carries waste from your building out to the sewer connection. It is common after repeated backups, sewage odors, or several slow fixtures at once.
Kitchen, laundry, and bathroom branch lines can collect grease, soap scum, and lint. Jetting helps when a clog keeps returning at the same fixtures.
Food service drains collect fats, oils, and grease along with food solids. Jetting removes that buildup from the drain line.
It does not replace grease interceptor service or good kitchen habits, which are what keep grease out of the line in the first place.
Roots enter pipes at joints and cracks. A cutting nozzle can clear them, but they often grow back if the joint stays open.
The camera tells us whether cleaning is enough or the pipe needs repair.
Restaurants, offices, retail shops, and mixed-use buildings put different loads on their drains. Restaurants usually have the heaviest grease.
Food service businesses in the City of Los Angeles are regulated under Los Angeles Municipal Code Section 64.30. That includes an Industrial Wastewater Permit and approved grease removal devices. Jetting is separate from those requirements.
For commercial jobs, we talk through affected areas and timing before work starts.

If snaking clears a drain for a few weeks and the clog returns, buildup may still be coating the pipe. Jetting cleans the wall, not just the blockage.

When more than one fixture drains slowly, the problem is often in a branch or main line, not in a single trap. A camera helps show where.

Grease cools and hardens inside pipes. LA Sanitation reports that tree roots and poured grease cause over half of sewer backups in the city.

Gurgling can point to restricted flow or a venting problem. Odors can come from a partial blockage. We inspect before deciding whether jetting is the right fix.
North Hollywood is in the City of Los Angeles. The public sewer main belongs to the city, while the pipe from your building to the main, including the part under the street, is the property owner's. A camera can help show which side of that line a blockage sits on.
Hydro jetting is one tool among several. A cable machine fits some clogs, and a camera and locating equipment help us decide what the line needs. We recommend the method that suits the pipe, not the one that sounds most impressive.
Nearby communities to ask about include:
It can be when the pipe is in sound condition and the pressure is matched to it. Cracked or brittle clay and cast iron may not be good candidates, which is why we inspect with a camera first.
A cable machine can cut through or pull out many blockages. Hydro jetting is used to clear grease, sludge, and buildup from the pipe wall. The camera helps us decide which one fits.
Cost depends on line length, access, pipe condition, the amount of buildup, and whether a camera inspection is needed. An accurate quote depends on seeing the situation. Call us for a free estimate.
In the City of Los Angeles, the property owner maintains the sewer lateral from the building to the street connection. The public sewer main belongs to the city. A camera inspection can help show where the blockage is.
In the City of Los Angeles, food service businesses that produce grease waste must hold an Industrial Wastewater Permit and use approved grease removal devices. Ask LA Sanitation about the requirements for your specific kitchen.
