What is the effect of my plumbing vents not working correctly?
Not having proper venting can cause the water in your traps to get sucked out with the other water disposal (commonly called a ‘dry trap’), which opens the door for sewer gases to back up out of the fixtures and into your living space. The resulting released gases not only smell bad but are actually explosive. Yes, the methane within sewer gas is quite dangerous. It’s not just an urban myth. It’s a problem you should take quite seriously.
