Going on Vacation? A Southern Tier Homeowner's Checklist to Protect Your Home from Plumbing Disasters While You're Away

You’ve packed the car, dropped the dog off with the kennel, and pulled out of the driveway for a week at the lake or a family trip down south. The last thing on your mind is what’s happening inside your walls. Unfortunately, a slow drip you never noticed can turn into thousands of dollars of ceiling and floor damage by the time you pull back into your driveway.

Vacation-season plumbing disasters are more common than most homeowners realize. A failed water heater, a burst supply line under a sink, or a stalled sump pump during a Southern Tier thunderstorm can flood a basement or ruin hardwood floors in a matter of hours — and there’s no one home to catch it. Insurance may cover the damage, but the cleanup, the deductible, and the disruption to your family are avoidable with a little preparation before you leave.

At Action Plumbing, Heating, and Cooling, we’ve responded to plenty of “we just got home from vacation” emergency calls across Binghamton, Endicott, and Vestal. Here’s the checklist we wish every homeowner would run through before locking the door.

Start with the Main Water Shutoff

The single most effective step you can take is turning off your main water supply before you leave for anything longer than a weekend. No water flowing in means no water flowing where it shouldn’t be. A cracked ice maker line or a failing washing machine hose can dump 5–10 gallons per minute into your home, but only if the water is on.

Your main shutoff is usually in the basement near where the water line enters the house, or in a utility closet on the ground floor. If you’ve never operated it before, test it once before your trip — older shutoff valves can seize up, and you don’t want to discover that at the last minute. If yours won’t turn or is leaking, this is a good time to schedule a professional plumbing repair before it becomes an emergency.

Put Your Water Heater in Vacation Mode

Most modern water heaters have a “vacation” or “VAC” setting that keeps the tank warm enough to prevent damage but stops it from heating water to full temperature while no one’s using it. This saves energy and reduces stress on an aging unit.

If your water heater is older, you can lower the thermostat manually. For gas water heaters, turn the dial to the vacation or pilot setting. For electric units, flip the breaker off entirely if you’re gone more than a few days. If your tank is already showing signs it needs replacement — rust-colored water, banging noises, or puddles at the base — don’t leave town without addressing it. A tank failure while you’re away can dump 40+ gallons of water into your basement or utility room.

Check the Sump Pump Before You Go

Summer thunderstorms in Broome County have caused plenty of basement flooding over the years, and if the power goes out or your sump pump has already been struggling, you’ll come home to a soaked basement. Before you leave:

Pour a bucket of water into the sump pit to make sure the pump kicks on and drains it fully.
Listen for grinding or straining noises that could indicate the motor is failing.
Check the discharge line outside to make sure it’s clear and directing water away from your foundation.
Consider a battery backup if you don’t already have one, especially if summer storms have knocked out your power before.

Our guide to seasonal flooding and sump pumps covers what to look for in more depth. If your pump is more than 7 years old, professional sump pump service before your trip is money well spent.

Look for the Warning Signs You’ve Been Ignoring

That toilet that’s been running for a month. The faucet that drips overnight. The small water stain on the ceiling under the upstairs bathroom. Small problems have a habit of becoming big problems the moment you’re not home to catch them.

Do a walk-through of the house looking for anything that could get worse. Check under sinks for moisture, look at the base of your water heater and washing machine, and note any spots where paint is bubbling or drywall feels soft. Our post on hidden water leak warning signs covers what to watch for, and the hidden cost of ignoring minor plumbing problems explains why these small issues matter so much when no one’s home to react.

A Few Extra Steps That Make a Big Difference

Turn off supply lines to washers and dishwashers. Even with the main water off, this protects appliances from any residual pressure.
Adjust your AC, don’t shut it off. Set it to 78–80° instead of turning it off. Humidity control protects wood floors, cabinets, and drywall.
Have a trusted neighbor check in. Give them a key and your plumber’s number in case something happens.
Program your smart water sensor if you have one. Set alerts to text your phone if any leak is detected.

What to Do If Something Goes Wrong Anyway

Even with the best preparation, plumbing emergencies happen. If your house-sitter texts you about water coming through a ceiling or a soaked basement, contact us right away. Our 24/7 emergency plumbing service covers Binghamton and the surrounding Southern Tier communities, and our post on plumbing emergencies that cannot wait outlines what qualifies as a true emergency and what can wait until you’re back home.

Common Vacation Plumbing Questions

Should I really turn off the main water for a short weekend trip?

For trips longer than 2–3 days, yes. For a single overnight, it’s less critical, but if your home has any known plumbing issues or your water heater is over 10 years old, we still recommend it. The 30 seconds it takes could save you from thousands in water damage.

Won’t turning off the water damage my plumbing?

No. Shutting off the main is perfectly safe. Pipes are designed to hold water without flowing. Just remember to run the faucets briefly when you return to clear any air from the lines before using appliances like the dishwasher or washing machine.

What if I have a well pump instead of city water?

The same principle applies. Locate the shutoff valve on the pressure tank or the electrical disconnect for the pump itself. Turning off power to the well pump stops any new water from entering the plumbing system while you’re away.

How do I keep my basement from smelling musty while I’m gone?

Leave your AC on with humidity control engaged, and consider a small dehumidifier for basement spaces. Also pour a cup of water down any floor drains before you leave — drain traps that dry out let sewer gas into the home.

Should I have a plumber inspect my home before a long trip?

If your home is older, you’ve had recent leaks, or you’ll be away for two weeks or more, yes. A pre-vacation inspection catches problems that a quick homeowner walk-through might miss. Our team serves Endicott, Vestal, and Johnson City and can often schedule these within a day or two.

Travel with Peace of Mind This Summer

A vacation is supposed to be a break, not a setup for coming home to disaster. Taking 20 minutes before you leave to shut off water, check your sump pump, and address any small warning signs can protect your home while you’re making memories elsewhere.
