The headline “The Real Deal on Covering Your Sink Before Vacation: The Truth About the ‘Upside-Down Glass’ Hack (And How to Actually Protect Your Home)” appears to be referring to a common household tip shared online. The idea is usually that placing an upside-down glass, bowl, or cover over a sink drain before leaving prevents problems while you’re away.
Here’s the practical truth:
- An upside-down glass over the drain may help as a temporary cover, mainly by reducing the chance that insects, debris, or odors enter through an open drain.
- It does not prevent the most common sink-related vacation problems, such as leaks from old plumbing, a dripping faucet, a clogged drain, or water damage from a pipe failure.
- A sink trap (the curved section of pipe under most sinks) already holds water, which normally blocks sewer gases from entering your home. If the home will be empty for a long time, drains can dry out, but a glass over the drain does not replace proper maintenance.
Before leaving for an extended trip, more effective steps include:
- Turn off the main water supply if you’ll be away for a long period.
- Check faucets, pipes, and connections for leaks.
- Clean drains and remove food residue from kitchen sinks.
- Run water briefly in all drains before leaving to keep traps filled.
- Ask someone to check your home periodically during long absences.
- Set your water heater appropriately and consider shutting it down if recommended for your situation.
The “upside-down glass” trick is a small precaution, not a complete home-protection strategy. It can be useful, but it should be paired with measures that actually reduce the risk of water damage and plumbing issues.
