Fair questions about high pressure water
Will jetting break my pipes?
In sound pipe, no. The jets are aimed at the wall to lift coating away, and pipe in good condition handles that without trouble.
In pipe that has already failed, high pressure water can find the weakness and make it worse. That is precisely why the camera pass is not optional and why some lines get a recommendation against jetting.
Is jetting just an expensive version of snaking?
They do different things. A cable cuts a path through an obstruction, and a jetter cleans the whole circumference of the pipe wall.
For a single clog, cabling is usually the better value. For a line that keeps coating and closing, cabling buys a season while jetting addresses the layer causing it.
My plumber wants to jet every year as maintenance.
On a commercial kitchen line with heavy grease, scheduled jetting can be reasonable and is often tied to how fast the line loads up. On a normal house line it usually is not.
Ask what evidence supports the schedule. If nobody can show you camera footage of the line coating up again, an annual jetting is a subscription rather than a repair.
Can jetting really cut tree roots?
Root cutting nozzles do remove root mass from inside the pipe, and roots reportedly cause more than half of all sewer blockages. Cleaning them out restores flow.
It does not close the opening the roots came through. Unless the joint or crack is repaired or lined, the roots return. Root removal is usually paired with a plan for the defect.
Do you need to dig up my yard to jet the line?
No. Jetting is done through an existing cleanout or another access point, and the hose travels inside the pipe.
Digging only becomes part of the conversation if there is no usable access, or if the camera finds damage that has to be repaired. Those are separate decisions with separate prices.
How much water does this use, and does that matter in the desert?
A jetter uses a meaningful amount of water during a job, supplied from a tank or a hose bib. It is a working cost rather than a trivial one in this valley.
The counterweight is that a line failing repeatedly wastes far more, through backups, repeat visits and eventually excavation. The Southern Nevada Water Authority takes valley water losses seriously enough to fund leak diagnostics with a voucher of up to $250.
