Works well to help clear blockage

Make sure there is no metal or plastic in your pipe if you use this tool, your blockedge must be soft.

Master shower was draining really slow one day, so I ran to HD and picked up one of those drain snakes that attaches to a drill, after running the auger it still was draining slower than normal. Not sure if it was the combo of snaking the drain first to break down the clog, or if I should have just started with this thing, either way it drains like the day it was new. At $70 for both tools it's still cheaper than calling a plumber.

We had a 3 inch drain pipe that had clogged up and nothing was working. I spent hours trying to snake it, used drain clearing chemicals, etc. Sometimes I would get a little bit of water to flow but for the most part it was a complete clog.With the pipe still filled with water, I attached this to my air compressor with a sprinkler air clean out adapter. The first blast of air didn’t work, the second blast didn’t work. Literally the third time was the charm. Yes, it made a mess everywhere, spraying water out of the pipe and making a stinky dirty mess. So I would recommend plugging a pipe with towels if you use this method. But it WORKED. Finally we can do laundry without worrying about another backup.
