Stan shot this video of me working on a slow drain. I had to buy a new snake, manually operated 25 foot. New snake didn’t work and I was stumped! The clog actually got worse and clogged completely. I eventually brought out the Sears pneumatic gun. This device uses the air compressor to shoot a 95 LB/sq inch shot down the drain. You have to have standing water in the pipes for it to be effective because air is compressible It took about ten shots for the clog to clear.
This Sears Drain Cleaner probably does not have the power to clear a clogged sewer line.
All is fine now. Sorry I don’t have video of the complete process.
