Signs you need this
- Tub water climbs whenever someone flushes upstairs
- Gurgling from the sink after the washer drains
- Floor drain weeping or smelling of sewer gas
- Slow drains on more than one fixture
Kit on the van, and the method
- Drum auger with ¼–⅜ in. cable for 1½–2 in. branches
- Sectional machine and cutting heads for 3–4 in. mains
- Self-levelling camera and locator
- Trap wrenches, cleanout keys, drop sheets
Before we leave: Run several fixtures at once and watch the lowest drain for any rise.
How a jetter works
A hydro jetter pumps water at high pressure through a flexible hose to a nozzle with jets angled backward. The rearward jets pull the hose forward along the pipe and blast the walls on their way past. One forward jet breaks through the blockage ahead. As we draw the hose back, the spray sweeps the loosened material down toward the main.
Good candidates
- Kitchen lines coated with fat that refill weeks after cabling.
- Mains with fine root hair that keeps catching paper.
- Long horizontal runs under a slab with sludge sitting in the bottom.
- Commercial kitchens with heavy grease loads.
When we will not jet
Jetting is not right for every pipe. Before running it on an older lateral we want to see the line on camera, because high pressure aimed at a cracked clay pipe or a separated joint can make the damage worse and wash bedding soil into the line. Thin-walled or badly corroded cast iron can be harmed too. If the pipe is fragile, we say so and suggest a repair first.
The order of work
- Camera the line to confirm material and condition.
- Open the main if it is fully blocked, usually with a cable.
- Select a nozzle: a piercing nozzle for plugs, a spinning nozzle for fat, a root head for growth.
- Jet from the cleanout outward, in passes.
- Camera again to show the before and after.
How long it lasts
A clean pipe stays clean if the inputs change. Grease scraped into the garbage instead of the sink keeps a jetted kitchen line clear for years. Roots are different: jetting clears them, but the open joint they found remains, so regrowth is likely unless the joint is repaired. Our main line clearing page covers cabling, and camera inspection explains the look before and after.
