Because I bought a canister drain auger today…

…and I’m trying to clear a blockage in the drain pipe for my kitchen sink. I got about fifteen feet in and around two turns, but then I couldn’t get it to turn again. If I’m understanding this video right (I cannot hear what he’s saying.): when I come to a turn in the pipes, I need to tighten the screw at the front of the canister before I start turning the wheel and that should get the snake turned in the right direction.

So, I guess I’ll try again tomorrow.
