The Homeowner’s Guide to Preventing Plumbing Damage During Vacations

Taking a vacation should be stress-free, but nothing ruins the post-trip glow faster than coming home to a flooded kitchen or a burst pipe. In Missouri, where seasonal weather shifts can affect plumbing systems, preparing your home before you leave is essential. With a few preventive steps, you can protect your home from costly water damage.

Why Plumbing Prep Matters Before Travel

When you’re away, even a small leak can become a major disaster. Without someone to spot and stop the problem, water damage can escalate quickly—leading to ruined flooring, mold growth, and expensive repairs.

In St. Charles County and surrounding areas, homeowners often face challenges like freezing winter temperatures, summer storms, and hard water buildup, all of which can put extra strain on your plumbing system.

Step 1: Turn Off the Main Water Supply

The simplest and most effective way to prevent plumbing damage is to shut off the main water valve. This stops water flow to your home and reduces the risk of leaks while you’re gone.

If you’re not sure where your shut-off valve is located or if it’s working properly, schedule a plumbing inspection before your trip.

Step 2: Drain and Winterize Exterior Faucets

If you’re traveling during colder months, drain your outdoor faucets and disconnect garden hoses. This prevents frozen pipes, which are a common source of leaks in Missouri winters.

For extra protection, consider installing frost-proof hose bibs. A licensed plumber can handle this upgrade as part of plumbing services in St. Charles.

Step 3: Inspect for Leaks Before You Go

A week or two before your trip, do a thorough walk-through of your home:

• Check under sinks for moisture
• Look for water stains on walls or ceilings
• Listen for running water in toilets or hidden leaks

If you notice anything suspicious, call for leak repair before you leave.

Step 4: Adjust Your Water Heater

For trips longer than a few days, set your water heater to “vacation” mode or turn it off entirely. This conserves energy and prevents the unit from overheating or leaking.

If your water heater is due for maintenance, our water heater repair and maintenance team can ensure it’s in top condition before you go.

Step 5: Clear Drains and Garbage Disposal

Slow drains can become clogged while you’re away, especially if food particles are left sitting in your garbage disposal. Run cold water with a little dish soap through the disposal to flush it before you leave. For deeper issues, see our guide on garbage disposal installation and maintenance.

Step 6: Have a Neighbor or Friend Check In

Even with precautions, having someone check your home every few days can make all the difference. They can spot problems early and take action before damage spreads.

Bonus: Install a Leak Detection System

For peace of mind, consider installing a smart leak detection system with automatic shut-off capabilities. These systems monitor water usage and shut down the supply if they detect unusual activity.

Why This Matters for Missouri Homes

Missouri’s weather extremes—from summer humidity to freezing winters—make plumbing systems more vulnerable when left unattended. Taking these steps helps you avoid costly repairs and maintain your home’s value.
