Got a call from a tenant. "I dropped something down the drain and now it is clogged. I need this fixed NOW!" In tenant speak "something" can be a wedding ring or a baby hippo. Got my shop vac with Clean Stream waterproof filter ( blatant plug ) and vacced out the drain. Got a bunch of small plastic toys Took 5 minutes from the time I walked in the door. If you have a clogged drain, try a shop vac. There are tons of yoo tube videos on how to do it.
