While it might look like a strange ritual, this clever trick actually solves a few common problems that crop up when a home sits empty for days or weeks.
Why People Cover Their Sink Drains Before Vacation
-
Preventing Sewer Gas and Odors: Every sink has a curved pipe underneath called a P-trap, which holds standing water to block sewer gases from rising into your home. If a sink isn’t used for an extended period, that water can slowly evaporate, allowing unpleasant smells to travel up through the plumbing. Blocking the drain keeps the air inside fresh.
-
Blocking Pest Infiltration: Cockroaches, sewer flies, and drain gnats actively seek out damp plumbing pipes. An unsealed, dry drain provides an easy entryway for pests into an empty house. Covering the opening physically seals off the entrance.
-
Catching Slow Leaks or Drips: Placing a paper barrier under an upside-down glass acts as an immediate indicator upon your return. If the faucet drips or a pipe backtracks while you’re away, the paper will be damp or crumpled, alerting you to a plumbing issue before you turn the taps back on.
-
Slowing Down Water Evaporation: Covering the drain opening traps moisture inside the P-trap, significantly slowing down the evaporation process during hot summer months or dry winter heating seasons.
