Heavy duty drain cleaning tool

Attach a length of PVC tubing with ½" NPT thread.

Brush is optional but recommended for heavy duty cleaning. I used this one, but anything with ¼ pipe thread will work. Cleaning and Deburring Tube Brush for Copper, 1/4 NPSM Male, 2-3/4" Diameter with Nylon Plastic Bristles | McMaster-Carr

Attach the other end of the PVC to a garden hose to get a custom length brush with 360° water spray pattern.
