Emergency Water Shutoff Guide for Missouri Homeowners
Every minute matters when water is pouring into your home. Whether it’s a burst pipe, leaking appliance, or overflowing fixture, knowing how to shut off your water quickly can prevent thousands of dollars in damage.
At Purisync Heating and Air, we respond 24/7 to water emergencies across Kirkwood and surrounding Missouri cities. Here’s a step-by-step guide to help you take action before we arrive.
1. Locate the Main Water Shutoff Valve
Your home’s main water shutoff valve controls all water flow from the city supply or well. It’s usually found in one of these places:
- Basement near the front foundation wall
- First floor utility room or crawl space
- Inside the garage (wall facing street)
- Outdoor meter box near the curb (may require a key or wrench)
To shut it off: Turn the valve clockwise (right) until it stops.
2. Shut Off Individual Fixtures (If Needed)
If the problem is isolated to one fixture (like a sink or toilet), shut off the valve beneath it:
- Toilet: Behind the base on the wall — small oval valve
- Sink: Inside the cabinet under the sink — two valves for hot/cold
- Washing machine: Wall valve or box behind the machine
- Water heater: Valve above the heater on the cold water line
3. Turn Off Electricity If Water Is Near Outlets
Water and electricity are a dangerous mix. If water is near outlets or electrical panels:
- DO NOT step in water if the electricity is still on
- Shut off your main circuit breaker if it’s safe to reach
- Call 911 if there’s an electrical fire or severe risk
4. Call for Emergency Water Removal
After the flow is stopped, immediate water extraction and drying are critical. Contact Purisync for:
- 24/7 emergency water removal
- Damage inspection and moisture assessment
- Drying, sanitizing, and repair
