How to deal with a drain:
Drain clogs happen. They can be anything from a slight annoyance to an expensive disaster. Quite possibly, you can deal with the issue yourself. However, the situation may be beyond your control.
Sometimes, in the case of a lavatory or sink drain, it may be possible to remove the strainer and clear the clog that way. If the clog is not within reach, you can try removing the p-trap under the sink, and clear that. If the clog is beyond the trap, the snake may be needed. And then, if your home maintenance efforts fail, in may be time to call upon your local qualified plumbing professional for assistance.
