A foul smell coming from your basement drain is more than an inconvenience. It is a clear warning that potentially flammable and hazardous gases are entering your home thereby putting your family at risk. There are many causes and solutions of drain smells in the basement but here a few of them that are very common.
Old cast iron piping
If you have older cast iron piping you may be getting the smells through cracks in your pipes. This kind of piping has a tendency of forming some cracks over time along the topside of the pipe. It is very difficult to detect the cracks of this type of piping in the basement.
A dry trap
This is a frequent cause, and pouring some water into all floor drains, sinks, and tubs may correct the problem. All drains usually have a trap that provides a seal to keep out sewer gases and is always filled with water. If your basement drain is rarely used, water evaporates from trap with time and the seal is eliminated allowing sewer smell and gas into your house.
A clogged vent on the roof usually creates backpressure so that when you try to put water into the pipe it slows the water down and begins to clog the pipe. A clogged pipe may also be as a result of leaves or other debris like hair and soap.
Lack of required traps or vents
A trap and vent pipe helps to keep basement drain smells from entering the home. Therefore, it is important for every fixture to have these two fittings.
