Topic: Opening Completely Stopped Drains
In some cases, using a simple suction cup will open a clogged sink drain.
Step 1: Simple Solutions: First, remove the basket strainer from the drain (Fig. 1).
Run hot water until it stands about 2" deep in the sink.
Take a suction cup plunger and pump it up and down directly over the clogged drain. The water in the sink provides a seal. If the suction cup does not clear the drain in a few minutes, you will probably be forced to remove some of the pipes to get the job done.
