What a hydro jetter does inside your drain
A hydro jetter is a pump, a water tank and a long hose, usually carried on a truck or trailer. The nozzle on the end has jets that point backward, so the water pulls the hose forward through the pipe while it scours the walls. Grease, soap scale, silt and fine root hairs get cut loose and flushed toward the main sewer.
A drain cable works differently. Its steel head spins through the blockage and leaves a hole, but a coat of grease or scale stays on the pipe wall. That is why a line that was snaked last spring can clog again by fall.
The pieces that make up a jetting quote
Plumbers price jetting by the job, not by the minute, and the job changes with the pipe. Ask which of these items are in your number and which could be added once the camera shows what is inside.
| Factor | What changes | Why it affects the price |
|---|---|---|
| Line length and diameter | A 40 foot kitchen branch versus a 100 foot lateral to the street | Longer and wider pipe takes more hose, more water and more time |
| Access point | A clean-out outside, a pulled toilet, or a roof vent | Poor access adds setup and sometimes a second crew member |
| What is blocking the line | Grease, roots, scale, packed sludge or a collapsed section | Heavy buildup needs several passes. A collapse cannot be jetted at all |
| Camera inspection | A sewer camera run before and after | It adds time but shows whether jetting is safe and whether it worked |
| Hour of the call | Weekday daytime versus a backup at night | Ask dispatch how an after-hours visit is priced |
| Repairs found | A cracked joint, a belly or a root-filled fitting | Jetting clears the symptom, but a broken pipe needs a separate repair quote |
Ask whether the quote covers a camera look afterward. Footage of the clean pipe is the proof the job worked, and you can keep it for a home inspector or your records.
Standards and guidelines for jetting
Jetter manufacturers publish pressure and nozzle guidelines by pipe type, and the 2021 International Plumbing Code (IPC) adopted in Connecticut governs any repair afterward. A careful plumber runs a camera first so the right setting is used.
Want a price for your own line?
Describe the clog and where the drain is. We explain what the job involves and state a clear price before work starts.
Jetting or snaking: which one fits your clog
Drain cable (snaking)
- Best for a single soft clog, such as hair in a tub or paper in a toilet line
- Faster setup, usually the lower price
- Leaves a film of grease or scale on the pipe wall
- Can hang up on a root mass instead of clearing it
Hydro jetting
- Best for grease buildup, scale, silt and recurring clogs
- Cleans the full pipe wall, not just a channel through the middle
- Can cut fine roots, but it will not repair a broken pipe
- Needs a camera check first on old or fragile pipe
Many Farmington homes only need a cable. If a kitchen line backs up every few months, or the whole house drains slowly, jetting is worth pricing. Our hydro jetting page covers the symptoms in more detail, and the sewer line cleaning page explains what happens when the blockage is out in the main.
When jetting is the wrong tool for old cast iron
Cast iron drain pipe was common before the 1960s, and Census Bureau estimates (ACS 2020 to 2024) show about 25 percent of Farmington homes were built before 1960. Inside that old pipe you often find rough rust scale called tuberculation, and in some spots the wall is thin. High water pressure on a thin wall can open a crack or knock loose a rusted section.
Signs to stop and look before anyone jets
- Rust flakes in the water that comes out of a clean-out or a cable run
- A sagging section that holds water, which the camera shows as a belly
- Visible cracks or offset joints where two pipes no longer line up
- A past repair with a patch or a clamp that could be forced loose
- Clay or fiber pipe (older sewer laterals) that can break under the force
If any of these show up, the plumber should say so and offer a gentler cleaning, such as a cable with a cleaning head, or a repair quote. Getting that honest answer is the real value of a camera first.
Why the camera comes first
Talk through the symptoms
Tell the plumber which drains are slow, how often it happens and whether a past cleaning held. This narrows down where the blockage sits.
Run the sewer camera
A small camera on a flexible rod travels down the line from a clean-out and shows the pipe material, the buildup and any damage.
Review the footage together
You see what the plumber sees. If the pipe is sound, jetting is safe. If it is not, you learn that before money is spent.
Get the price
The quote now reflects the real length, the real blockage and any repair that turned up. A clear price comes before work starts.
Jet, then re-check
After the cleaning, a second camera pass confirms the walls are clear and no new damage appeared.
If you are buying a house, a camera run also doubles as a sewer inspection. Many buyers use it to learn about the lateral before closing.
Sewer lines in Farmington and the next-door towns
Farmington sewer lines, permits and where jetting stops
The Town of Farmington runs the Water Pollution Control Facility, which treats flow from Farmington and Unionville, Avon, Canton and Burlington and uses more than 150 miles of pipe and 17 pumping stations. Jetting your own house line does not touch any of that. But if the camera finds a crushed pipe and the fix means digging, Town Code Chapter 156 comes in: a permit from the Town Engineer, a licensed drainlayer, and an inspection before the trench is backfilled.
The code does not say in plain words who owns the lateral past your property line. Ask the Town Engineer before you assume, and get the answer before you sign a repair quote.

In Newington, a short drive east, the Metropolitan District Commission (MDC) says the homeowner owns and maintains the sewer lateral. It also asks you to call its Command Center at (860) 278-7850, press 1, before any work starts, because it will not assume liability if you call after. Our Newington page has more on that town's older housing, where the median home was built in 1967.
In Bristol, sewer service runs through the city's Water and Sewer Department, and about 25 percent of homes there date to before 1950. If you live in the Bristol area, ask the city who handles which section of the line before you schedule any digging.
What a plumber can and cannot promise
Be wary of any plumber who names a price for a main line without seeing it, or who promises that jetting will end every clog for good. Roots return, grease returns and a damaged pipe stays damaged. You can check any plumber's state license on Connecticut eLicense (elicense.ct.gov), run by the Department of Consumer Protection.
Insurance rarely pays for routine drain cleaning, since it counts as maintenance. Sewer backup coverage, if you have it, is usually a separate endorsement. Read your policy or ask your agent.
