Turning off your home’s water supply before vacation is one of the best ways to protect your property. Water leaks can occur at any time. These leaks become particularly dangerous when you’re away and unaware of the situation. A faulty appliance could flood your home for days if you leave the main water valve on during your absence.
The decision to turn off water during vacation should be automatic. Your home stays protected from extensive water damage when you shut off the main water valve before leaving. Most homeowners face water damage from leaky pipes and connections due to maintenance problems.
Let us show you the simple steps to shut off your home’s water supply before your trip. You’ll also learn about extra safeguards like draining water lines and adding leak detection sensors. These sensors give early alerts about potential water issues throughout your home.

Step 1: Shut off your main water valve
Turning off your home’s main water valve is your best defense against unexpected water damage. This quick task takes just minutes but saves you thousands of dollars and prevents major hassles.
Why this is the most effective protection
Water damage ranks among the most destructive things that can happen to your home. A tiny crack in a water pipe can leak about 250 gallons of water in a single day. The water keeps flowing at high pressure while you’re away if you don’t shut off your main supply.
The costs can add up. On top of that, it takes just 24 hours for dangerous mold to start growing in flooded areas. Insurance companies expect homes to have daily monitoring. Some might even void your policy if you don’t turn off your water supply during extended absences. So this simple step isn’t just practical – it protects your finances too.
How to turn off the water when on vacation
Finding your main water valve is the first vital step. You’ll usually spot it:
- In the basement near the front wall (closest to the street)
- In a crawl space
- Near your water heater or inside your garage (for homes built on slabs)
- Where the main pipe enters your house foundation
The valve comes in two types: a ball valve with a straight handle or a gate valve with a round handle. Ball valves need the handle turned from parallel to perpendicular position. Gate valves require clockwise turning until they stop.
Once you’ve shut off the main valve, turn on several faucets around your house. This drains remaining water from the pipes – something that’s really important in winter.
Do I need to turn off the water when on vacation?
Yes, you should. Experts recommend this step even if you’re just away overnight. Some homeowners worry about frequent on-off cycles, but this won’t damage your plumbing system.
This becomes even more important during winter. Water can expand inside pipes when it freezes and cause bursts that lead to major flooding. Summer brings its own challenges too – higher temperatures increase water pressure that can make existing cracks worse.
Your home might have options that let you cut off the main water supply while keeping outdoor sprinkler systems running. This way your garden stays watered while you’re gone.
Step 2: Prepare your plumbing system
The main water valve is just the first step to protect your plumbing system during your absence. A few more steps will safeguard your pipes, cut down energy costs, and help you spot potential issues before they become serious problems.
Drain the remaining water from the pipes
After turning off the main supply, you need to remove any water left in your pipes. This becomes even more important when you travel during winter. Start at the highest floor and work your way down as you open all faucets in your home. Empty the toilet tanks by flushing them. Cold weather travelers should pay extra attention to this step because water can freeze and burst pipes.
Your system needs a complete drain, so open the faucet in your lowest sink or laundry tub. This lets gravity help clear out the system. Keep all faucets open while you’re gone so any leftover water can escape instead of building up pressure in your pipes.
Set your water heater to vacation mode
Modern water heaters come with a “VAC” or “VACATION” mode on their temperature dial. This setting reduces the unit’s temperature to save energy while keeping basic functions running. Gas water heater owners should turn the gas valve to ‘pilot.’ Electric water heater users can use vacation mode or lower the temperature to about 50 degrees Fahrenheit.
Vacation mode brings several advantages. You’ll save money since there’s no need to heat water to 120 degrees in an empty house. Your system gets protection from freezing damage in cold weather. The risk of corrosion and mineral buildup in your water heater also goes down.
Check for leaks or corrosion in advance
Before you leave, take a good look at all visible pipes and plumbing fixtures. Watch out for:
- Blue stains that show copper corrosion
- Rust on galvanized pipes
- Pinhole leaks with rusty, bluish, or white sediments around them
Look carefully under sinks, around toilets, behind appliances, and at all water supply connections. Small leaks might seem minor, but can cause big damage if left unchecked for long periods. Keep in mind that corrosion wastes much water through leaks and might force you to replace entire pipes.
These steps create multiple layers of protection for your home’s plumbing system while you’re away.
Step 3: Add backup safety measures
Adding backup safety measures creates an extra layer of protection for your home, even when your main water valve is off. These simple precautions detect problems early and minimize damage while you enjoy your vacation.
Install smart leak detectors
Smart leak detectors alert you to water problems before they cause major damage. These Wi-Fi-enabled sensors detect moisture and send notifications straight to your smartphone. Place them strategically near water sources:
- Under sinks and behind toilets
- Next to washing machines and water heaters
- Near dishwashers and refrigerators
The basic models cost a few hundred dollars, and installation is straightforward – just position the device near potential leak sources or connect an extension node in hard-to-reach spaces. Advanced systems can automatically shut off your water supply when they detect leaks, offering complete protection during your absence.
Test your sump pump
Your home’s last defense against basement flooding is your sump pump. Test it before leaving by pouring water into the sump pit – the pump should activate right away and remove water.
Look for these warning signs:
- Excessive vibration or loud noises during operation
- Visible rust or corrosion
- The pump runs continuously or fails to start
Sump pumps usually last about 10 years, so older units need extra attention. A battery backup system helps maintain protection during power outages.
Keep your thermostat at a safe level
In stark contrast to this popular belief, shutting off your HVAC system while away creates more problems than it solves. Summer vacations require setting your thermostat around 85°F to prevent excess humidity that warps wood floors and causes mold growth.
Winter temperatures should stay between 50-60°F to protect against frozen and burst pipes. The temperature should never drop below 45°F, as this substantially increases your risk of plumbing disasters.
These safety measures, combined with turning off your main water valve, will provide complete protection for your home during your absence.
Step 4: If you can’t shut off the water completely
You can’t always turn off your home’s water supply completely. You might need to keep your sprinklers running, water your house plants, or your main valve might be hard to reach. Don’t worry – you still have good options to protect against water damage.
Turn off the water to the washing machine, dishwasher, and toilets
When the main water supply stays on, you should focus on shutting off individual appliances that could cause problems. Washing machines cause the most trouble – they’re behind more than 30% of all home water damage insurance claims.
Look for dedicated shutoff valves behind your washing machine and dishwasher. Your toilets have oval-shaped valves on the water line near the floor. Turn these clockwise until they stop. You can also turn off specific zones if your home has separate water shutoff valves.
Use stainless steel hoses for added safety
Regular rubber washing machine hoses usually fail after five years, often without warning. Braided stainless steel hoses offer much better protection. These steel-reinforced hoses:
- They are much more resistant to bursts than rubber ones
- They last 10-15 years when installed properly
- They handle water pressure up to 1,500 PSI (rubber only manages 800 PSI)
They cost a bit more ($20-30 per hose), but this small investment helps you sleep better when you can’t shut off your water completely.
Should you shut off the water when on vacation, but need sprinklers?
Your lawn needs water while you’re away, but you can still keep your home’s interior safe. The best option is a separate water line just for outdoor irrigation. This lets you cut off water to your home while your sprinklers keep running.
Some newer homes come with dual water systems that have separate shutoff valves for indoor and outdoor water. If your home doesn’t have this feature, ask a trusted neighbor to check on your property or install smart water sensors that send leak alerts to your phone.
Most water damage happens because appliances fail or connections break, not from mainline problems. Taking care of these specific weak points usually gives you enough protection when you can’t shut off all the water.
Final Thoughts
You need a multi-layered approach to protect your home from water damage while you’re away. The most effective step is to shut off your main water valve. Draining your pipes, setting your water heater to vacation mode, and checking for leaks will create a solid foundation for protection.
Smart leak detectors, working sump pumps, and proper thermostat settings will give you vital backup protection if something goes wrong. You still have options when you can’t shut off the water completely. Turn off individual appliance valves and upgrade to stainless steel hoses to substantially reduce your risk.
Take 30 minutes to go through these steps before your next trip. This small investment could save you thousands of dollars and spare you countless headaches. Your vacation should focus on relaxation and enjoyment instead of worrying about flooding disasters at home. These preventative measures will help you come back to the same dry, damage-free home you left.
