Leaving Town This Summer? The Pre-Vacation Plumbing Checklist for Kennesaw Homeowners

A burst supply line or a failed water heater is bad enough when you are home to shut the water off. While you are at the beach for a week, that same leak can pour thousands of gallons into an empty house, soaking floors, ceilings, and walls long before anyone notices. The fixes are simple and take about fifteen minutes total. Run this checklist before your next summer trip and leave Kennesaw with one less thing on your mind.
Why an empty house is a plumbing risk
Plumbing does not take a vacation. Your supply lines stay pressurized the entire time you are gone, so any weak hose, worn valve, or aging water heater is under constant strain with nobody watching. Water damage is one of the most common and expensive home insurance claims, and a slow leak that runs for days does far more damage than the same leak caught in an hour. The goal before you leave is simple: take away the pressure, and you take away the risk.
Takeaway: The danger is not the leak itself, it is the days it runs unnoticed in an empty house.
Shut off the main water supply (the single best step)
If you do only one thing on this list, do this. Shutting off your home's main water valve before a trip eliminates almost every catastrophic leak scenario at once. With the main off, a failed hose or cracked fitting simply cannot flood the house, because there is no pressurized water to spill.
Your main shut-off is usually where the water line enters the home, often in the basement, garage, crawl space, or near the water heater. Turn it clockwise until it stops, then open a faucet to confirm the water is off. For shorter trips, you can instead shut off the valves to your highest-risk appliances, like the washing machine and dishwasher.
Takeaway: Main valve off means no pressurized water in the house, which removes the worst-case flood entirely.
Set your water heater to vacation mode
There is no reason to keep heating a full tank of water for an empty house. Many water heaters have a vacation or VAC setting that keeps the tank from freezing without heating to full temperature. If yours does not have one, simply lower the thermostat. For longer trips you can turn it down further. This saves energy and eases the strain on a unit that may already be near the end of its life.
Takeaway: No one is showering while you are gone, so let the water heater rest and pocket the energy savings.
Check the high-risk connections before you go
Spend a few minutes on the spots most likely to fail:
• Inspect washing machine hoses for bulges, cracks, or rust, and swap aging rubber hoses for braided steel.
• Look under kitchen and bathroom sinks for drips or corrosion at the supply lines.
• Check around the base of toilets and the water heater for any moisture.
• Confirm the dishwasher and refrigerator water-line connections are dry.
• Clear any slow drains so nothing backs up while you are away.
Takeaway: Washing machine hoses and water heaters cause a big share of vacation floods, so give them the closest look.
Mind the AC and ask a neighbor to check in
In a Georgia summer, do not switch the AC fully off while you travel. A house with no cooling turns hot and humid, which invites mold and lets your AC condensate drain breed clogs. Set the thermostat higher to save energy while still keeping humidity in check.
Finally, ask a trusted neighbor or friend to walk through the house once or twice while you are gone. A five-minute look can catch a problem days before you otherwise would. Leave them your number and the location of the main shut-off valve, just in case.
Takeaway: A higher AC setting and one neighbor with your phone number are cheap insurance against a week-long disaster.
Your quick pre-trip checklist
• Shut off the main water valve (or the washer and dishwasher valves).
• Set the water heater to vacation mode or lower the thermostat.
• Inspect washer hoses and under-sink supply lines.
• Check the water heater and toilet bases for moisture.
• Clear any slow drains.
• Set the AC higher, not off.
• Give a neighbor your number and the shut-off location.
Takeaway: Print this, run it the morning you leave, and you have closed the door on nearly every vacation water disaster.
Frequently Asked Questions
Should I turn off my water heater when I go on vacation?
You do not need to turn it off completely, but you should set it to vacation mode or lower the thermostat. There is no reason to keep heating a full tank for an empty house. Lowering it saves energy and reduces wear, while still keeping the tank from any risk of freezing on a rare cold night.
Where is my home's main water shut-off valve?
It is usually where the main water line enters the home, often in the basement, garage, crawl space, or near the water heater in Kennesaw homes. Turn the valve clockwise until it stops, then open a faucet to confirm the water is off. It is worth locating before you travel so you are not searching during an emergency.
Should I turn off the water if I leave for a weekend?
For a short trip, shutting the main off is still the safest choice, but at minimum close the valves to the washing machine and dishwasher, the two most common sources of sudden leaks. For any trip longer than a couple of days, turning off the main water supply is strongly recommended.
What causes the most water damage in empty homes?
The most common culprits are failed washing machine hoses, leaking water heaters, and burst supply lines under sinks or behind toilets. These run continuously under pressure, so a failure while you are away can release thousands of gallons. Shutting off the main water supply prevents nearly all of these scenarios.
Can I leave my AC off while on vacation in Georgia?
It is better to set it higher rather than off. A closed-up house in a Georgia summer gets hot and humid, which encourages mold and can let your AC condensate drain clog. Raising the thermostat keeps humidity in check and protects the home while still saving energy.
