Common drain problems are, as the name suggests, very common.
Sooner or later we will all have to deal with a slow drain (if left long enough, almost all clogged drains will eventually drain.) While the problem is a common one, what causes a slow drain can vary drastically.
Some problems can be cleared quickly and easily. Others will require a fair bit of detective work before you can begin to address the actual problem.
Clogged sinks and toilets are generally the easiest to fix yourself. These blockages are often caused by a build up of hair or other material in the drain. Some of these blockages can be cleared by using warm water or a plunger to break up the clog and allow the free flow of water through your pipes. A double sink can present a unique set of challenges in clearing a drain but most of these clogs should be cleared quickly. If not, call a professional plumber to clear the clog.
When the main drain line exiting your home is clogged, you will have a more difficult time clearing the drain by yourself. When attempting to clear your main clogged drain line, there are a few things that you need to keep in mind. First of all, the main drain leaving your home is much larger then the rest of the pipes in your house. This means that when it is clogged, it is clogged with a lot of material. Secondly, access to the main drain line is limited. In order to block harmful sewer gasses from entering your home, access to the main drain line is not direct.
Finally, clearing the clogged drain line is difficult if you do not have the proper tools. A clogged exit drain will generally require a power auger to break through the clog (or clogs) in your main drain line. When you consider that the clog may be as far as fifty feet from the drain, I recommend calling a professional plumber.
