My building maintenance guy can't quite communicate with me, or doesn't
want to. Every time I ask them to come up and clean the stoppage in my
bathtub, they charge $30. He uses an industrial-type device that works like
this... you crank it (like an old water well) building up the air pressure.
When you have enough pressure, you put the nozzle end over the drain hole
and press a trigger, which releases all the compressed air into the hole.
This never fails to unclog my tub drain (the only one that clogs here).
Does anybody know the exact name of this device and where I can buy it? I
know it is going to be over $100, but I don't mind.
