Coming home from a relaxing vacation should feel like stepping into your little slice of paradise. But what if you open the door to a foul smell wafting from your sink drain? Yikes! It’s a common problem that can instantly spoil your warm welcome back. Luckily, there’s a simple trick to keep those nasty odors at bay before you even leave! 🌴✨
How Drain Odors Develop When You’re Away
The main culprit behind those unpleasant odors is the siphon, also known as the trap. This curved pipe beneath your sink holds a small amount of water that acts as a barrier, preventing sewer gases from sneaking up into your home. It’s an essential part of plumbing that keeps our living spaces smelling fresh.
But here’s the catch: when your house sits empty for days or weeks—especially in hot summer weather—the water in the siphon can slowly evaporate. Once that protective barrier disappears, unpleasant sewer gases can escape, and when you return, the smell can be strong enough to make you want to head straight back outside for some fresh air!
