How to Shut Off Water in a Plumbing Emergency | CNS Plumbing Services
When a pipe bursts or a fixture starts leaking uncontrollably, panic can quickly set in. But one of the most effective ways to minimize damage is something every homeowner should know how to do: shut off your water supply. This one simple action can save you thousands in water damage and costly repairs. At CNS Plumbing Services, we’re big believers in empowering our customers in Polk County and surrounding areas to take fast, informed action when plumbing issues strike.
Whether it’s a leaking toilet, a burst pipe, or a water heater failure, this step-by-step guide will show you how to locate and turn off your home’s water supply in an emergency.
Why You Should Know Where Your Water Shutoff Valve Is
Emergencies don’t wait for convenience. If a pipe bursts while you’re out or your toilet starts overflowing at 2 AM, you need to act quickly. Knowing where your shutoff valve is—and how to use it—can mean the difference between a minor cleanup and extensive water damage.
Step 1: Identify the Type of Plumbing Emergency
Before running outside or turning knobs, figure out what you’re dealing with:
-
Leaky toilet or sink: May only require turning off a localized valve.
-
Burst pipe or major leak: Shut off the main water valve immediately.
-
Leaking water heater: Turn off water supply and electricity or gas if safe to do so.
Understanding the severity helps you choose the right shutoff point and avoid unnecessary stress.
Step 2: Locate the Main Water Shutoff Valve
For most homes in Texas, the main shutoff valve is located:
-
Outside: Near the foundation on the street-facing side of the house.
-
In colder climates: Inside the home, in a utility area, garage, or basement.
-
Near the water meter: Often close to the curb in a utility box (you may need a meter key to access it).
Look for a round or lever-style valve—often brass or metal. If it’s a round knob, turn it clockwise (right) until it stops. If it’s a lever, turn it perpendicular (90 degrees) to the pipe.
Step 3: Shut Off Water at the Source (If Applicable)
For isolated problems like a leaking toilet, faucet, or appliance, you may be able to avoid shutting down the whole house.
Here’s how:
-
Toilet: Look behind the toilet for a small valve at the base. Turn it clockwise.
-
Sink: Check underneath the sink for hot and cold water shutoffs—turn both clockwise.
-
Washing machine: Look behind the unit for two valves (hot and cold). Shut them both off.
Localized shutoffs are great for minor issues and allow you to keep water flowing elsewhere in the home.
Step 4: Drain the Pipes (If Needed)
Once water is shut off, you may want to relieve any remaining pressure:
-
Turn on the lowest faucet in your home (often an outdoor spigot or bathtub).
-
Open a few other faucets around the house to release pressure and minimize leaks.
-
If it’s cold outside and pipes might freeze, draining the lines can help prevent further damage.
Step 5: Call a Professional
After you’ve shut off the water and ensured safety, it’s time to bring in the pros. Even if you’ve stopped the flow, a burst pipe or faulty valve can’t be ignored. CNS Plumbing Services offers same-day emergency plumbing in many cases across Polk County and nearby areas.

Pro Tips from CNS Plumbing
-
Label your shutoff valves: Use tags or colored tape so family members know where and how to shut off water in an emergency.
-
Keep a meter key handy: If your shutoff is inside a ground box near the curb, you’ll need one to open it.
-
Perform a test run: Practice turning the valve once or twice a year to make sure it’s not stuck or corroded.
-
Install automatic shutoff devices: Smart plumbing systems can detect leaks and cut off water automatically—great for frequent travelers.
