🧼 Why Put a Glass Over Your Sink Drain Before Vacation?

Going away on vacation? You may have heard an unusual tip: cover your sink drain with a sheet of paper and place an upside-down glass over it. But why would anyone do this?

At first, it sounds strange, but there’s a simple idea behind the trick.

🏠 What’s the Purpose?

When a sink sits unused for several days or weeks, the water inside the drain trap can gradually evaporate. That water normally acts as a barrier against sewer gases and unpleasant odors coming back through the drain.

Covering the drain can help reduce the chance of odors, insects, or other unwanted things entering through the opening while the sink is unused.

🥛 Why Use a Glass?

The upside-down glass provides a simple physical cover over the paper and drain. It can help keep the paper in place and create an additional barrier.

However, the glass-and-paper method isn’t a guaranteed substitute for maintaining the drain trap. A better approach for a longer trip is to make sure the trap has water in it and, if appropriate for your plumbing, use a proper drain stopper or cover.

✈️ A Simple Vacation Reminder

Before leaving home, it’s a good idea to:

• Clean the sink and drain.
• Make sure there are no food particles or debris.
• Keep drains covered when they won’t be used.
• Check that toilets and other plumbing fixtures have water in their traps.
• Consider asking a plumber about proper preparation if you’re leaving for an extended period.

Sometimes the simplest household tricks have a practical reason behind them!
