First, usually the sink clogging is mostly downpipe U-bend accumulation of debris, resulting in poor drainage. If the downpipe with sewage screws, directly remove it (to prevent dirty cabinets, it is best to pad a sewage basin underneath), unloaded, with a wire/steel wire on both sides of the dredging, it should be able to be successfully resolved. If it is not resolved may have to remove all the downpipe, remove all the plastic connectors and rinse, reassemble, I believe it will not take more than 30 minutes to get it done.

Second, the kitchen sink downpipe is often greasy debris, vegetable residue clogging, unblocking before the downpipe can be introduced to a pot of boiling water, and then use the rubber pipe/hooks and so on into the downpipe, remove debris. If you live on the first floor it could be a buildup of leaves or sludge.

Third, prepare a rubber hose, not too long, as long as you can connect the water cage and the sewer pipe. Insert one end of the pipe into the mouth of the sewer pipe, stuffed tightly around with worn rags or towels, the other section of the pipe is fixed to the tap water pipe, and then open the water cage head to the maximum, rinse for two or three minutes, the sewer pipe can be unblocked.
