When your drain is stopped or really slow, it is seldom the result of collapsed or defective pipes. Blockage in the lines is usually caused from many different things. Mostly from solid waste, small objects, hair, or clumps of soap and grease. What you need to do is isolate the problem. If one of the fixtures seems to drain slow or not at all, check and see if the other fixtures have the same problem. If only one fixture is the problem, fill the sink with water. If the water drains for two seconds or less before clogging, the problem is in the trap. If two or more fixtures are clogged, the clog may be in the branch line, the main line, or the vent stack. When you isolate the affected area, it will help you decide how to clean out the line-and whether you need to hire a professional.

Remember, drain lines are very fragile. They are probably more fragile than you would expect because of all the fixtures attached to them. You will need to be careful when using chemicals and augering. Some chemicals can weaken the walls of the drain lines, and augers can shatter porcelain fixtures. If either one of those don’t work, try to snake the line, but work slowly and carefully. There is a risk when you use chemicals. It is best to avoid them if possible. But if you do decide to use one, be sure that you FOLLOW ALL DIRECTIONS when using it. Never use a drain cleaner on a clogged drain or in a toilet, and never pour acid in standing water.
