I have a clogged kitchen sink drain. This kitchen sink has a waste disposal unit attached and seems to back up nearly completely (drain so slow you can't notice the water going down) but once the disposal is run it drains very quickly. After cleaning the trap I ran water through just the waste disposal unit into a bucket and it didn't seem to back up at all. I suspect there must be a clog somewhere in the drain pipe but why would it then drain so quickly with the disposal on? Any advice is appreciated!
