How To Shut Off Your Main Water Valve In An Emergency
The sound of rushing water is soothing if you’re standing near a waterfall or a rocky stream. But that same sound coming from a basement, crawl space, or bathroom is the stuff of homeowner nightmares.
A burst pipe can cause thousands of dollars in damage to your home. You can avoid costly repairs if you shut off your main water valve when an emergency strikes. But don’t wait until you’re fumbling in your pajamas with a flashlight in hand. Learning how to shut off your main water valve now will help you avoid damage when a major leak does happen.
Why Every Florida Homeowner Should Know How to Shut Off the Main Water Valve Before a Water Emergency
Florida’s homes are just as prone to burst pipes as homes in the North. What Florida lacks in freezing temperatures, it makes up for in regional conditions that leave pipes vulnerable to failure. And there are plenty of plumbing emergencies that call for a professional.
Hard Water
Florida is known for its hard water almost as much as it’s known for its sunshine. That’s because most of our water comes from an aquifer below limestone bedrock. When water travels through limestone to this massive aquifer, it picks up minerals like calcium and magnesium. The resulting hard water wreaks havoc on homes’ plumbing systems.
Freezing Temperatures
It doesn’t happen often, but freezing temperatures do hit the Sunshine State, particularly in the north. And homes built here are less protected from sudden freezes. Pipes lack insulation and are often exposed in unprotected crawl spaces, which are most commonly found in older Florida homes, built in the 1970s or before.
Excessive Water Pressure
Florida water utilities increase water pressure to service tall buildings and meet demand. But this increased water pressure combined with corrosive hard water can lead to burst pipes.
Minutes Matter When a Pipe Bursts
When a pipe bursts in your home, you need to act fast to avoid damage. A half-inch pipe can hemorrhage 50 gallons of water each minute. And the amount of water that soaks your walls, fixtures, and floors is even higher with larger pipes. Quickly turning off the main water valve is the fastest and most surefire way to avoid plumbing issues that could cost thousands of dollars in damage.
Where Is the Main Water Shut-Off Valve in a House?
The location of the main water shut-off valve varies by home. There are some usual suspects, however, when locating the shut-off valve in Florida homes.
- Exterior Wall: Look for a pipe fitted with a valve on the exterior of the house. Typically, the pipe will be on the side of the house that faces the street.
- Garage: Look for the shut-off valve on the wall joined with the house or near a utility sink.
- Utility Closet: If your home has a utility closet where the HVAC system or water heater are located, you may find your shut-off valve there.
- Underground: Sometimes, the main water shut-off valve is located in an underground utility box. The water utility box typically requires a “key,” which you can purchase online or at a local hardware store. Contact your water utility with any questions regarding the utility box.
- Basement or Crawlspace: If you’re the rare Florida homeowner with a basement or crawlspace, your water shut-off valve may be located there.
What Does the Main Water Valve Look Like?
Your water supply shutoff will have one of two valve types. Gate valves, found on older homes, feature a circular wheel handle. Newer homes feature a ball valve that looks like a lever.
Gate Valve
“Righty tighty, lefty loosey” applies to gate valves. To turn off a gate valve, rotate the wheel to the right. Rotate it to the left to open it again. Gate valves require several turns of the wheel to turn completely off or on.
Older gate valves have a tendency to get stuck. Never force a stuck gate valve. Doing so can break it and cause a leak. Fixing a leak at a gate valve often involves calling the water utility to temporarily turn off service to the home. Instead, try the following fixes for a stuck gate valve.
- Spray the valve with WD-40 or PB Blaster and let it soak for 30 minutes before trying the valve again.
- Gently tap the valve stem with a hammer to break up the mineral deposits within the mechanism.
- Call an expert plumbing team for a gate valve replacement.
Ball Valve
Found in most newer builds, ball valves are easier to operate and less prone to failure than gate valves. Ball valves feature a lever handle that only requires a quarter turn to open or close the valve.
When the ball valve is open, it will be in line with the water pipe. A closed ball valve will be at a right angle to the water pipe.
Ball valves are far less likely than gate valves to become stuck. If your ball valve is stuck, try applying a lubricating spray and allowing it to set for 15 to 30 minutes. If it still doesn’t work, call Hardenburgh Plumbing to fix it before you need it.
Where Are Fixture Shut-Off Valves?
Not every leak requires shutting off water to your entire home. If the problem is isolated to a toilet, sink, or appliance, you may be able to stop the water at the fixture instead.
- Sinks: Look beneath the sink for shut-off valves on the water supply lines. Turn the valve clockwise until it stops.
- Toilets: Find the valve on the wall or floor behind the toilet and turn it clockwise to shut off the water.
- Washing Machines: Look for the hot and cold water valves behind the washing machine and turn both off.
- Dishwashers: The shut-off valve is often beneath the kitchen sink on the dishwasher’s water supply line.
If you can’t find the fixture valve, the valve won’t turn, or the leak is coming from a pipe rather than a single fixture, shut off the home’s main water valve instead.
Common Mistakes to Avoid When Shutting Off the Main Water Valve
Most of the time, shutting off the main water valve is straightforward once you find it. Still, there are some common pitfalls to avoid.
- Don’t wait until an emergency. Regularly check your main water valve to ensure it works.
- Don’t force a stuck valve. Forcing a stuck valve can cause far worse damage. Instead, call the water utility to turn off the service, and then call an emergency plumbing service.
- Don’t ignore small leaks. The puddle in the basement that you’re wiping every other day will get worse. Call a trusted plumbing team to fix it today.
What to Do After You Shut Off the Main Water Valve
