What is hydro jetting and when do you need it?

Author: scraper  |  Last update: Sunday, September 27, 2026

Hydro jetting is a heavy-duty plumbing method that uses streams of highly pressurized water (up to 4,000 PSI) to scour the inside of drain and sewer lines. It completely blasts away sludge, grease, mineral scale, and tree roots, rather than just poking a hole through blockages like a traditional drain snake.

Is hydro jetting a good idea?

What is the 135 rule in plumbing?

In plumbing, the "135-degree rule" is a code standard that dictates how much a horizontal drain pipe can bend or change direction.
