Few things can ruin a vacation faster than getting a phone call from a neighbor telling you water is pouring out from under your garage door.
Unfortunately, it happens more often than most homeowners realize.
Whether you’re leaving for a long weekend, a family vacation, or an extended trip, your plumbing system continues working even when you’re not home. A small leak that might normally be noticed within a few hours can continue for days—or even weeks—before anyone discovers it.
At Ascend Plumbing, we’ve helped homeowners throughout San Diego, La Jolla, Del Mar, Rancho Bernardo, Chula Vista, Point Loma, Poway, and communities across San Diego County return home to everything from minor leaks to major water damage. Fortunately, a few simple precautions before you leave can dramatically reduce your risk.
Here’s the checklist we recommend before locking the front door.
Why Vacation Plumbing Problems Become So Expensive
When you’re home, you notice things.
You hear a toilet running.
You spot water under the sink.
You notice your water heater making unusual noises.
When you’re away, those same problems continue around the clock.
A leaking washing machine hose can release hundreds of gallons of water.
A failed water heater can flood a garage.
A burst pipe inside a wall can quietly damage insulation, drywall, flooring, cabinetry, and even your home’s structure before anyone notices.
That’s why preparation matters.
- Shut Off Your Home’s Main Water Supply
If you’ll be away for several days, one of the smartest things you can do is turn off your home’s main water supply.
Doing so eliminates the risk of a burst pipe or major plumbing leak continuing while your home sits empty.
If you aren’t comfortable locating or operating the main shutoff valve, Ascend Plumbing can show you where it is during your next plumbing inspection.
Every homeowner should know its location before an emergency happens.
- Turn Off Your Water Heater (If Appropriate)
If your water supply is turned off, your water heater should not continue operating normally.
Depending on the type of system you have:
Traditional Tank Water Heater
Set the control to “Vacation” mode if available, or follow the manufacturer’s recommendations.
Tankless Water Heater
Many systems include vacation settings or energy-saving modes.
If you’re unsure, consult your owner’s manual or ask your plumber during routine maintenance.
- Inspect for Small Leaks Before Leaving
Take ten minutes to walk through your home.
Look around:
- Bathroom sinks
- Kitchen sink
- Toilets
- Water heater
- Washing machine
- Dishwasher
- Refrigerator water line
- Outdoor hose bibs
Even a slow drip can become a much larger problem while you’re gone.
- Check Your Washing Machine Hoses
Washing machine supply hoses are one of the most common sources of residential water damage.
Inspect for:
- Bulges
- Cracks
- Rust
- Loose fittings
- Corrosion
If the hoses appear worn, replace them before your trip.
It’s an inexpensive repair that could prevent thousands of dollars in water damage.
- Test Your Sump Pump (If Your Home Has One)
While many homes throughout San Diego don’t have sump pumps, some properties do.
If yours does:
- Pour water into the pit.
- Verify the pump activates.
- Confirm water is discharged properly.
A failed sump pump during heavy rain can quickly become an expensive problem.
- Clean Your Drains
Slow drains often become complete blockages over time.
Before traveling:
- Flush bathroom sinks with hot water.
- Remove hair from shower drains.
- Clean kitchen sink strainers.
- Empty garbage disposals.
If you’ve experienced recurring slow drains, consider scheduling professional drain cleaning before your trip.
- Ask Someone to Check Your Home
If you’re away for more than a week, ask a trusted neighbor, friend, or family member to stop by occasionally.
Have them look for:
- Water around the water heater
- Wet spots on flooring
- Running toilets
- Dripping faucets
- Water stains
- Unusual plumbing noises
Catching a leak early can significantly reduce damage.
- Know the Warning Signs Before You Leave
Don’t ignore plumbing problems simply because your vacation starts tomorrow.
Schedule service if you notice:
- Rising water bills
- Low water pressure
- Water stains
- Slow drains
- Sewer odors
- Warm flooring
- Leaking pipes
- Water heater leaks
Minor repairs are almost always easier—and less expensive—than returning home to a flooded house.
What About Smart Leak Detection?
Today’s plumbing technology offers homeowners another layer of protection.
Smart water monitoring systems can:
- Detect unusual water usage
- Alert you through your smartphone
- Identify continuous leaks
- Automatically shut off water on some systems
- Help prevent catastrophic water damage
For homeowners who travel frequently or own vacation properties, these systems can provide valuable peace of mind.
Common Mistakes Homeowners Make Before Traveling
Before leaving town, many homeowners accidentally increase their risk by:
- Leaving the water on for extended trips.
- Ignoring a small leak until they return.
- Forgetting to inspect the water heater.
- Leaving worn washing machine hoses connected.
- Assuming someone else will notice a problem.
- Skipping a quick plumbing walk-through.
Just fifteen minutes of preparation can help prevent days—or weeks—of cleanup later.
When Should You Schedule a Plumbing Inspection?
If you’re planning an extended vacation, especially if your home is older, a professional plumbing inspection can identify issues that may not be obvious during a quick walk-through.
An inspection may include:
- Leak detection
- Water pressure testing
- Water heater inspection
- Shutoff valve testing
- Drain evaluation
- Pipe inspection
- Fixture inspection
Knowing your plumbing system is in good condition allows you to enjoy your vacation with greater confidence.

Did You Know?
Insurance companies often expect homeowners to take reasonable precautions when leaving a home vacant for an extended period. Shutting off the water supply and addressing known plumbing issues before leaving may help reduce the risk of significant property damage. Review your specific homeowners insurance policy to understand its requirements and coverage.
Ascend Expert Tip
One of the first questions we ask after a major water loss is, “How long was the leak running?” If you’re going to be gone for more than a few days, turning off your home’s water supply is one of the simplest—and smartest—steps you can take. It only takes a minute, but it can prevent weeks of repairs.
