You’re about to hit the road, hop on a plane, or finally sail off into that relaxing vacation you’ve been planning forever. But before you swap your morning coffee for poolside mojitos, there’s one thing you don’t want to forget, your plumbing. Yes, really.
Here’s the thing: while you’re off living your best life, your house keeps humming along quietly, and if something goes wrong with the plumbing while you’re not there to catch it, it can go from zero to flood fast. Think burst pipes, leaky water heaters, or a garbage disposal that forgot how to behave. It happens more often than you think, and it can cost thousands to clean up.
That’s why smart vacationers take a few minutes to run through some easy, preventative plumbing tasks before heading out. And we’re not talking about anything complicated or tool-heavy, just a quick checklist that could save you a serious headache (and bank account damage) later.
Whether you’re leaving for a long weekend or a month-long sabbatical, these vacation plumbing tips for homeowners are your secret weapon to peace of mind. Because nothing ruins a tan faster than coming home to a soaked carpet and a waterfall in the laundry room.
So grab your sunglasses, set your email to out-of-office, and let’s make sure your plumbing doesn’t throw a party while you’re gone. Here are the vacation plumbing tips every homeowner should know before locking that door.
1. Shut Off the Main Water Valve (Yes, All the Way)
If you only follow one of these vacation plumbing tips for homeowners, make it this one.
Turning off your main water supply is like sending your pipes on vacation, too. No pressure, no flow, no chance of a sneaky leak turning into a flood while you’re away. You can usually find the shutoff valve in your basement, crawl space, or near the water meter. Turn it off, give it a test by turning on a faucet, and relax knowing your biggest risk is now off the table.
If someone’s popping in to water plants or feed your cat, consider just shutting off the supply lines to high-risk appliances, like your washing machine, dishwasher, and icemaker.
2. Switch Your Water Heater to Vacation Mode
Your water heater is a hardworking appliance, constantly heating water whether you’re home or not. But if you’re not going to be using hot water while you’re gone, give it a break.
Most newer models have a “vacation” or “pilot” mode. This keeps the system running low and slow, enough to prevent freezing in colder climates, but not using up unnecessary energy. If your unit doesn’t have this setting, you can manually lower the thermostat to about 50°F.
It’s a simple step that not only extends the life of your system, but helps reduce your utility bill while you’re sipping cocktails somewhere sunny.
3. Unplug Small Appliances Around the House
This is not exactly plumbing, but it’s all part of the same peace-of-mind package.
Unplug things like your coffee maker, toaster, desktop computer, and electric kettle. You’ll prevent phantom energy drain and reduce the risk of electrical fires. Plus, it’s just good vacation hygiene.
4. Clean Out Your Garbage Disposal (Trust Us on This One)
No one wants to come home to a house that smells like a compost bin.
Before you leave, give your garbage disposal a quick rinse with cold water and a splash of vinegar or lemon juice. Run it for a few seconds to flush everything out. This is one of those vacation plumbing tips for homeowners that seems tiny, until you return home and realize what a big deal it really was.
5. Check for Leaks One Last Time
Do a quick walkthrough of your kitchen, bathrooms, and laundry area. Look under sinks, behind toilets, and around appliances for signs of slow leaks, drips, water stains, moisture. If you see something suspicious, don’t wait. Fix it or call your plumber before you go.
You’d be surprised how much damage a single drop can do when left alone for a week.
6. Consider a Leak Detection Device or Smart Shutoff Valve
Want full peace of mind while you’re away? Install a smart water shutoff valve or leak detection device. These clever little gadgets alert you to water issues via your phone, and some can even shut off the water automatically.
It’s one of the best vacation plumbing tips for homeowners who travel often or for extended periods of time. The investment upfront pays off the first time you dodge a major leak while on the beach.
7. Let Your Home Look Lived-In
While this doesn’t directly involve pipes, a house that looks obviously vacant can become a target for theft or mischief, which could lead to broken pipes or vandalism. Put your lights on timers, pause your mail, and ask a neighbor to swing by and check in.
It’s all part of keeping your home safe, inside and out.
Give Your Plumbing a Pre-Vacation Checkup
Your vacation should be full of beach days, mountain hikes, or doing absolutely nothing, not emergency calls to a plumber because your living room became a wading pool. Following these vacation plumbing tips for homeowners means you can leave with confidence and return to a house that’s just as you left it.

Frequently Asked Questions
How long does my house need to be empty before shutting off the water is really worth it?
For anything longer than an overnight, shutting off the main is a smart, low-effort habit. Even a long weekend gives a small drip or a failing supply line plenty of time to do real damage when no one is around to notice. The longer the trip, the more it pays off, so when in doubt, turn it off.
What if someone is staying at or checking on my home while I’m away?
If a house-sitter, pet sitter, or plant waterer needs running water, you don’t have to shut off the whole house. Instead, close the supply valves to your highest-risk appliances, like the washing machine, dishwasher, and ice maker, which are the most common sources of surprise leaks. That keeps the kitchen and bathroom usable while still trimming your risk.
I can’t find my main shutoff valve, or it won’t budge. What should I do?
Start by checking your basement, crawl space, garage, or the wall nearest where the water line enters the house, and look around the water meter as a backup. If the valve is stuck, corroded, or you simply can’t locate one, don’t force it, since an old valve can break under pressure. Give us a call before your trip and we can locate it, free up a stiff valve, or replace one that’s past its prime.
Is it safe to fully turn off my water heater while I’m gone, or just lower it?
Using the vacation or pilot setting, or lowering the thermostat to around 50 degrees, is the easygoing middle ground that saves energy without fully shutting the unit down. Completely turning a gas heater off means relighting the pilot when you return, and powering down some electric or tankless models can be more hassle than it’s worth for a short trip. For a week or two away, the vacation setting is usually the sweet spot.
How do I know if a slow leak is something I can ignore until I get back?
There’s no such thing as a leak worth ignoring before a trip, because a slow drip with no one home can quietly warp floors, feed mold, and stain ceilings over a week or two. If you spot dampness, a musty smell, water stains, or a faucet or toilet that keeps running, treat it as a reason to act now. Tighten or shut off what you can, and if you’re unsure, have it looked at before you lock the door.
Are smart leak detectors and automatic shutoff valves worth it for an occasional traveler?
They shine most for frequent travelers, second-home owners, or anyone away for long stretches, but even occasional travelers appreciate the phone alert that catches a problem early. Detectors simply notify you of moisture, while automatic shutoff valves go a step further and close the water on their own. If you’d like help choosing a setup that fits your home and plumbing, we’re glad to walk you through the options.
