There are several common reasons your drains might smell bad. Sometimes proper plumbing maintenance falls by the wayside and problems arise. Slow drainage caused by a clog and even drains that smell terrible are pervasive. Our team at Avant Rooter has listed the top four reasons why your drains and plumbing may have a bad-smelling order.
Check P-Traps to make sure they are working correctly. Drains under a bathroom or kitchen sink will have visible P-traps. On the other hand, floor, shower and toiler drains are hard to see. However, most drains have an adequately vented P-trap, and most P-traps have a supply of water going through them to keep the “trap seal” working properly.
Clogged Vent Pipe
All plumbing systems have a vent system specifically for the plumbing in the home or building. Its purpose is to equalize the pressure caused by wastewater running through the system and allow sewer odors to escape. If this venting is somehow blocked, odors can’t be released outside and can build up inside the building.
The issue with Sewer Line
If you have ever walked into your home or business and smells like rotten eggs, you will most likely have a sewer gas leak. Sewer gas is a byproduct of the breakdown of natural human waste. The hydrogen sulfide in sewer gas is what gives it is signature rotten egg smell.
Improper Use of Garbage Disposal
The garbage disposal can create a bad odor from some rotten tiny food particles that are either stuck or cling to the garbage disposal cylinder, cutting blades and sometimes the splash guard that cause the growth of bacteria that produces the foul odor.
