Hydro jetting FAQ

It is a drain-cleaning method that pumps high-pressure water through a hose to a nozzle with mostly rear-facing jets. The jets pull the nozzle up the pipe, scrub the wall and flush debris to the main.

Snaking uses a spinning cable to bore through a clog. Jetting uses water to clean the full pipe circumference and carry the debris away. Snaking suits solid objects; jetting suits grease, sediment and fine roots.

On sound pipe of common materials, including clay, cast iron and plastic, yes when pressure and nozzle suit the pipe. On cracked, thin, soft or collapsed pipe, it can cause damage, so camera-inspect older lines first.

Sound cast iron tolerates jetting. Thin, corroded bottoms and aggressive descaling tools are the risk. A camera shows wall condition before cleaning.

Only with great caution, if at all. Bituminous fibre pipe softens and deforms with age; it is often a candidate for replacement rather than cleaning.

Residential trailer and cart jetters are often quoted around 3,000 to 4,000 psi. That is a typical range, not a rule, and flow matters as much as pressure.

Flow carries loosened debris out of the pipe and gives the nozzle pulling power. High pressure with low flow breaks material loose but leaves it behind.

Usually a rotating nozzle, sometimes a heavy self-rotating head, with hot water helpful for hardened grease. A penetrator may open a stopped line first.

It cuts and flushes roots inside the pipe, but roots regrow because the tree and the open joint remain. Lining or repairing the joint stops regrowth at that point.

Yes. Hot-water jetting melts ice and flushes the meltwater away. Cold-water jetting is slower and can refreeze.

Not usually with a proper cleanout. Mess risk rises when the line is backed up or access is through a fixture.

A typical residential main line is often done in one to three hours, including setup and camera. Heavy roots, grease or poor access take longer.

Most homes do not need scheduled jetting. Lines with recurring grease or root problems may benefit from an interval set by camera findings.

For a building sewer, generally not advisable. Consumer kits lack flow, and any jetter can cause injection injuries. Small branch lines are a different case, with care.

It happens when a high-pressure jet pierces skin and forces contaminated water into tissue. It can look minor but is a surgical emergency; go to an emergency department immediately.

A 2026 planning estimate for a residential main line with an accessible cleanout is often about $400 to $900 CAD, higher for roots, grease, poor access or after-hours work.

Strongly recommended, especially in older homes or with recurring clogs. It confirms the result and records defects for future decisions.

No. It clears what the sag collects, but the belly keeps holding water and debris. A repair is the fix.

Yes. Liners need a clean wall, so roots, grease, sediment and scale are removed and the pipe verified by camera first.

Usually not through the flap. Operators work downstream of it or remove the flap temporarily, then reinstall and check it.

It depends on the municipality's rules for the service line. Confirm with your municipality; in Calgary, call 311.

It is better not to. Chemical drain cleaners rarely clear main lines, and corrosive water left in a blocked line can splash the person who opens it. If you have used one, tell the contractor the product and amount before any cleanout is opened.

Often, yes. Intact foundation drains are flushed from the sump pit or a cleanout at low pressure with a flushing nozzle. Crushed, missing or disconnected tile needs repair instead.

It is when the cause is build-up such as grease, sediment or fine roots, because it removes the material rather than punching a hole through it. It is not worth it for a lodged object or a broken pipe.
