Home Repair – How to Unclog Blocked Drains and Pipes

With all of the advancements in technology and science over the years, there is one common household problem that has stood the test of time: clogged drains and pipes. These problems are unavoidable, considering everything that goes down our drains in the course of a day.

There are, however, many proven methods for unclogging pipes, some old and some new.

A pan of boiling water poured down the drain might work for metal pipes. If it's a minor clog, such as hair and soap, and there is not to much water backed up, the hot water may dissolve and free the clog. If so, continue rinsing with hot water.

This method is not recommended for plastic pipes, as the boiling water may cause leaks by softening the joints. There are other techniques that are better suited for pipes that are less heat resistant. Sometimes the problem may be hot grease that has dried on it's way down the drain.

Try a cup shaped plunger for more severely clogged drains. These are different from flange plungers, which are designed for use in toilet bowls.

Double sided sinks can be a bit trickier. You'll probably need to plug up one side while you plunge the other. A towel will usually do the trick. If possible, plunging both sides at the same time may work as well.

Plunging should be done in a short, quick motion. For best results, the affected area should receive quick bursts of pressure. If the blockage seems to have been dislodged, a rinse of hot water should again be applied to wash away excess debris.

If the blockage cannot be moved with a plunger, an auger or straightened coat hanger may be necessary. An auger is a coiled wire in a metal housing that is extended into the drain using a handle.

First, remove the drain cover and remove any hair and debris in that area. Sometimes this will take care of the problem. If not, the auger should be used carefully to avoid damaging the pipes and drain traps.

Slowly and firmly extend the auger into the drain a few inches at a time. The curvature of the pipes may provide resistance similar to that of the clog, so take your time in determining which is which. Continue turning the crank, while not being too forceful.

It's extremely important that you avoid damaging plastic pipes while using the auger. This will save you an even bigger repair job than what you started with, possibly requiring you to remove the pipe. Many augers are designed for use with a drill. Before attempting this, though, it's recommended that you try other methods.

Chemical drain cleaners can be used if none of these other methods prove successful. To avoid health risks and pipe damage, always follow the manufacturer's instructions. Safety equipment, such as gloves and goggles are recommended when using these products to avoid contact with skin and eyes.

If you've tried everything else and the pipe is still clogged, it may become necessary to remove the pipe itself. The most common problem area is the U-shaped bend in the pipe. If the problem is so severe that you are considering this option, it may be in your best interest to contact a professional plumber. Unless you have the proper skills and experience, some jobs are best left to the pros.
