Is your garbage disposal smelling more and more like the food scraps it’s supposed to be eliminating? A stinky garbage disposal isn’t pleasant to say the least. First you might catch whiffs of the stench while rinsing dishes, then you might be chopping veggies on the other side of the kitchen, and eventually the stink can permeate your entire house. If your garbage disposal smells like sewage, it’s time to take action – fast. Wonder why your garbage disposal smells like sewage no more, and instead take action by checking to see if you’re experiencing one of the issues below.
1. You need to clean your garbage disposal
Stating the obvious? Perhaps. But we can’t leave this one off the list. If your garbage disposal smells like sewage, try clearing out the disposal. It’s really easy for foodstuffs to get stuck to the blades, especially if you’re not running your disposal as often as you should. Try refreshing the disposal by putting lemon slices down the drain and letting the disposal blades grind them up.
2. Your P-trap (or S-trap) needs some TLC
If your disposal is clean, then perhaps your p-trap is dry. The p-trap should always have water in it, because this water forms a seal that blocks nasty smelling sewer gas from escaping into your home. If the p-trap is dry, it can’t do its job, and your nose will suffer. Have a plumber inspect the p-trap for leaks, blockages, or air pockets.
3. You have a ventilation problem
Your sewer line also needs to have proper ventilation. The sewer vent is usually accessible via the roof (be careful climbing up there), and can occasionally get clogged with leaves and other debris. You can try clearing it out by hand, or try running water down the vent opening with a garden hose. Clearing out the vent allows your system to maintain the appropriate pressure to seal away the sewer gas smells.
If you’ve tried all of the above and your garbage disposal still smells like sewage, it’s time to call in the professional. You could have a larger issues, such as a main sewer line clog, which will require the skills and tools of the pros.
