Drain Technician Career: Hydro Jetting, Sewer Cameras, Pay

A drain technician clears clogged sinks, floor drains, main lines and building sewers, then figures out why they clogged. On a residential service truck, that means cable machines, water jetters and sewer cameras. On a municipal or commercial crew, it can mean larger jetter and vacuum trucks, manholes and inspection reports that cities use to plan repairs.

It is one of the easier ways into the plumbing world. It is also a specialty that can stand on its own if you build the right skills. This guide covers what the work involves, what it pays according to federal data, which credentials help, and where the career can lead.

What a drain technician actually does

The federal O*NET profile for septic tank servicers and sewer pipe cleaners lists job titles including drain cleaner, drain technician and septic tank service technician. Typical tasks include:

• Locating stoppages, including inspecting manholes on larger systems.
• Running sewer cleaning equipment such as power rodders and high-velocity water jets.
• Digging out lines, breaking pavement to reach pipe, and cutting out and replacing damaged sections.
• Driving trucks with crews and equipment.
• Keeping records of maintenance and repair work.

In residential service, the daily rhythm is calls: a backed-up kitchen line, a basement floor drain, a main line full of roots. The technician clears it, runs a camera when the cause is not obvious, and tells the homeowner what they found. That last step is where drain work starts to overlap with sales and with full plumbing repair.

Hydro jetting: what the machines do

A water jetter pushes a hose into the line and sprays high-pressure water through a nozzle. Rear-facing jets pull the hose forward and scour the pipe wall, which is why jetting removes grease and sludge that a cable can punch through but leave behind.

Jetters come in a wide range of sizes. Two RIDGID models show the spread:

Truck- and trailer-mounted units used on municipal sewers run larger still. Part of becoming a good jetting tech is learning which nozzle and pressure suit which pipe. Old, cracked or root-damaged pipe needs a camera look before you hit it with high pressure.

Jetter safety is not optional

Pressurized water at these levels can cut skin. Spartan Tool's sewer jetter safety guide describes deaths caused by jet streams and by nozzles pulled out of a pipe while still pressurized. Its core rules:

• Do not start high pressure until at least 3 feet of hose is inside the pipe.
• Shut off pressure when the nozzle is within 3 feet of the opening on the way out. Never pull a live nozzle out of a pipe.
• Wear goggles at all times, and a full face shield above 2,000 psi, plus waterproof gloves, rain gear and boots.
• Expect noise above 90 decibels and protect your hearing.

Sewer camera inspection

A sewer camera is a waterproof camera head on a push cable. It shows the inside of the pipe on a monitor and records video. Many systems include a transmitter, called a sonde, near the camera head, so a technician on the surface can locate the head with a receiver and mark where and how deep a problem sits.

Camera work changes the job. Without it, a drain tech clears clogs. With it, the tech can tell a customer that a line has a belly, a root intrusion at a joint, an offset or a collapsed section, and show them the footage. That diagnosis is what leads to sewer repair, lining or replacement work. It also means accuracy matters: what you call a defect, and how you describe it, affects real decisions.

Habits that make a good camera tech

• Clear the line before you camera it when you can. Standing water and debris hide defects.
• Narrate as you push. Call out distances from the cleanout and what you see at each joint, so the recording makes sense to someone who was not there.
• Locate and mark the problem on the surface before you leave, with its depth.
• Describe, do not exaggerate. A homeowner will make a large spending decision based on your words. Show the footage and let it speak.

PACP certification for sewer inspection

On the municipal and commercial side, inspection work follows a standard. NASSCO's Pipeline Assessment Certification Program (PACP) is described by inspection equipment maker Deep Trekker as the North American standard for CCTV wastewater pipe inspection. It gives every inspector the same defect codes, sorted into structural, operation and maintenance, construction and miscellaneous categories, with a condition grade from 1 to 5.

• Initial certification: a two-day PACP course and exam, or a three-day course that adds LACP (laterals) and MACP (manholes).
• Validity: according to NASSCO's recertification page, certification lasts three years. If it lapses, you start over with the initial course.
• Recertification: online self-paced (completed within 60 days) or a one-day trainer-led course, or two days for all three programs.

For a residential drain tech, PACP is not usually required. For anyone who wants to work for utilities, municipal contractors or engineering firms doing pipeline assessment, it is a clear résumé line.

Drain technician pay: what the data says

Federal data does not have a separate "drain technician" category. The closest is septic tank servicers and sewer pipe cleaners. O*NET, drawing on Bureau of Labor Statistics data, reports for 2025:

Plumber figures are from the BLS Occupational Outlook Handbook. O*NET projects much faster than average growth for sewer pipe cleaners from 2025 to 2035, but on a small base, with about 2,800 openings over the decade.

Two caveats. First, the federal category mixes septic pump truck drivers and municipal sewer workers with residential drain techs, so it is a rough guide. Second, residential drain techs at service companies are often paid under commission or per-task plans, which can push earnings above or below these medians. Before accepting a commission plan, ask for a sample paycheck from a slow week, and remember that commissions still count toward overtime under federal rules.

Do you need a license to clean drains?

It depends on the state. Texas is a clear example of a state that regulates drain work specifically. The Texas State Board of Plumbing Examiners offers Drain Cleaner and Drain Cleaner-Restricted registrations as add-ons to an apprentice registration, each renewed annually with six hours of continuing education. Other states treat drain clearing as unlicensed work as long as you do not repair or replace piping, and some cities have their own rules.

The practical line in most places: clearing a stoppage is one thing, but cutting out and replacing pipe, or repairing a sewer lateral, is plumbing work that usually needs a license and a permit. Check our state-by-state plumbing licensing guide before you take on repairs.

The hazards nobody puts in the job ad

Drain and sewer work is dirty, and some of it is dangerous:

• Sewer gas. OSHA's hydrogen sulfide hazard page notes that the rotten-egg smell disappears at around 100 to 150 ppm because the gas deadens your sense of smell, and that concentrations of 700 ppm and above can cause unconsciousness and death within minutes. Do not trust your nose.
• Confined spaces. OSHA lists manholes and vaults among confined spaces. In construction, a competent person must identify permit-required confined spaces before work begins, and entry requires a written program. Never enter a manhole or deep pit without training, atmospheric testing and a rescue plan.
• Biological exposure. Sewage carries pathogens. Gloves, eye protection and handwashing before eating are basic habits.
• Rotating cables and high-pressure water. Cable machines can wrap gloves and fingers; jetters can cause the injuries described above.
