Drain cleaning machines that use high pressure water spray up to 3000 psi are called?

  1. Blow bags

  2. Augers

  3. Jetters

  4. Rooters

The correct answer is: Jetters

Jetters are cleaning machines that use high pressure water spray up to 3000 psi. Blow bags are used for clearing clogs in drains but do not use high pressure water. Augers are a type of plumbing snake that are used to clear obstructions in pipes. Rooters are a type of machine that use sharp blades to cut through clogs and roots in drains. None of these options use high pressure water spray up to 3000 psi, making jetters the correct answer.
