What to expect on a hydro jetting visit, from arrival to camera proof

01 /How should you prepare for a jetting visit?

Preparation mostly comes down to clearing access and stopping water use. The fewer surprises the operator finds, the faster the job goes.

1. Find the cleanout if you can. Common spots are a capped pipe on the basement floor near the front wall, a threaded plug on the building drain near the stack, or an exterior cleanout near the foundation. If you do not know, say so when booking.
2. Clear a path from the door to the cleanout and about a metre or more of working space around it. Move stored boxes away from floor drains.
3. Stop water use if drains are backing up: no laundry, dishwasher, showers or flushing.
4. Tell the contractor about chemicals if any drain cleaner or root treatment has gone into the line recently; drain cleaner vs hydro jetting explains why it changes how they start.
5. Note the history: when symptoms started, which fixtures are affected, previous cleanings, any known repairs or camera reports.
6. Keep children and pets away from the work area and the equipment outside.
7. Plan for the rig: a trailer jetter needs parking close to the house; a truck may need the driveway.

02 /What happens when the contractor arrives?

1. Symptoms and history

   The operator asks which fixtures are affected and when, and whether the line has been cleaned or inspected before. This narrows down where the blockage is and what it may be.

2. Access check

   They open the cleanout carefully. If the line is backed up, water may be standing in the cleanout; experienced operators loosen caps slowly and stand to the side.

3. Camera or initial opening

   On older homes or recurring problems, many operators camera first. If the line is full of water, they may open it with a cable or penetrating nozzle so the camera can see.

4. Rig setup

   The jetter stays outside. The hose is run to the cleanout, protected where it crosses floors, and the water supply is connected or the onboard tank is checked.

5. Nozzle choice

   A penetrator for a stopped line, a rotating head for grease, a root nozzle for roots, a flushing nozzle for sediment.

03 /What does the jetting itself look like?

The jetting itself is usually quieter inside the house than people expect, because the engine and pump are outside. Inside, the operator feeds hose into the cleanout and controls water with a foot pedal or hand valve. The nozzle pulls itself up the line; the operator lets it advance, pulls it back, and repeats in sections so loosened material is flushed out rather than pushed ahead. You may hear water rushing in the pipes and see dirty water at the cleanout.

• Passes: a line is usually jetted several times, sometimes with different nozzles.
• Distance: the operator tracks how much hose is in the line to know where the nozzle is relative to the house, property line and main.
• Return water: it should run from dark and full of debris to clearer as the line cleans. Unusual soil or gravel suggests a break.
• Time: most of the visit is setup, passes and verification; the jetting of a typical residential line is often under an hour.

Why flow matters more than the pressure number is explained in pressure vs flow, and the nozzle options in jetting nozzles explained.

04 /What proof should you get at the end?

You should get evidence that the line is open along its full length and an explanation of any defects. The best evidence is a camera pass after jetting, with video you can keep. At minimum, you should see a sustained flow test: water running from upstream fixtures without backing up.

SewerInspector.ca explains how to read inspection footage and defect descriptions if you want to review the video yourself.

05 /What if the contractor recommends a repair?

A repair recommendation after jetting is common, because jetting uncovers defects that were hidden. That does not mean the recommendation is wrong, but it is a separate decision from the cleaning. Ask for the video and footage, ask what the repair would be (spot repair, lining, replacement) and why, and get more than one quote. A defect that has existed for years usually does not need to be fixed the same afternoon, unless the line cannot carry flow.

06 /What does a jetting visit cost?

Residential jetting is usually priced as a flat rate for a main line with accessible cleanout, with extras for camera inspection, difficult access, after-hours work, heavy roots or grease, and long runs. The detail is on the hydro jetting cost page.

When you are ready, the quote request form collects the details contractors need, and the jet-or-auger decision tool helps you ask for the right service.

07 /What are the red flags on a jetting visit?

• A refusal to show camera video, or a camera run without a recording.
• A repair price quoted before anyone has looked inside the pipe.
• Pressure to sign a large repair contract on the spot, with vague reasons.
• No explanation of what the blockage was.
• Jetting a line the camera shows is collapsed, without discussing the risk.
• An invoice that does not separate cleaning, camera and other charges.

The good signs are the mirror image: the operator asks about the history before opening anything, explains the nozzle choice, shows you the camera screen as the line is inspected, and describes defects by footage and type rather than in vague terms. They separate what must happen today (restoring flow) from what can be planned (repairs), and they are comfortable with you getting a second opinion on anything larger than the cleaning itself.

None of these automatically means bad faith, but each is worth a question. Good operators are usually happy to explain their work. If jetting itself is being recommended and you are unsure it is needed, is hydro jetting worth it sets out when it is justified and when it is an upsell, and the Jetter Power Calculator lets you check that the rig suits your line size.
