How to Sonic Clean a Clogged Well Casing

Sonic cleaning may be your one and only answer when you come across impenetrable grime. Well casings, for example, that are clogged and corroded are often packed with hardened gunk that is stuck to well-casing lids and walls. Ultrasonic cleaning sends sound waves into concrete-like grime. The sound waves break up the physical nature of the grime at the molecular level, thus fracturing the hardened gunk and making it possible to remove.

Screwdriver
Crowbar
20- to 80-kHz ultrasonic contact transducer
Steel fiber brush

Instructions

- 1
  Drain the well casing as necessary via your home well user's manual. Unscrew and pry open the casing lid, respectively, with a screwdriver and a crowbar.
- 2
  Power on a 20- to 80-kHz ultrasonic contact transducer. Touch the head plate of the transducer atop the casing surface. Move the head plate over the surface of the casing in a back-and-forth motion at a low and controlled speed. Contact transducers are designed for removing grime from flat areas and move naturally over top flat surfaces. Purchase a contact transducer though your local well or sonic cleaning supply company.
- 3
  Reduce the frequency to between 20 and 40 kHz to send low-frequency waves to brake up large pieces of hardened grime. Increase the frequency to 41 kHz or higher to send high-frequency waves to brake up smaller piece of hardened grime. Turn off the transducer.

  Scrub the casing and lid clean with a steel fiber brush.
