A burst pipe or backed-up drain can put gallons of water where they don’t belong in minutes. What you do in the first few minutes — before a plumber ever pulls up — has a big effect on how much damage you’re left with. Here’s the short list for McKinney and North DFW homeowners.
1. Shut off the water
This is step one for almost any emergency. If the problem is at a single fixture — a toilet, sink, or water heater — close the small stop valve on the supply line right at that fixture (turn clockwise). If it’s a burst pipe or you’re not sure where the water is coming from, go straight to the main shut-off and close the whole house. Knowing where that valve is before trouble strikes saves you the worst minutes.
2. Turn off the water heater if needed
If you’ve shut off water to the whole house, or the heater itself is leaking, switch it off so it doesn’t run dry. Set a gas unit to “pilot” or off; flip the breaker for an electric unit. This protects the burner or heating element from damage.
3. Stop the electricity to wet areas
Water and electricity don’t mix. If water is near outlets, appliances, or the electrical panel, shut off power to those circuits at the breaker — but only if you can reach the panel safely and aren’t standing in water. When in doubt, stay clear and let us handle it.
4. Contain and protect
- Move furniture, electronics, and valuables away from the water.
- Put down towels or a bucket to slow the spread and catch active drips.
- Lift drapes and rugs off a wet floor.
- Clear a path so the technician can get to the source fast.
5. Don’t use the affected plumbing
If a drain or sewer line is backed up, stop running water into it — no sinks, showers, dishwasher, or laundry — until it’s cleared, or you’ll add to the backup. For a suspected slab or supply leak, leaving the water off until we arrive prevents further damage.
6. Document it for insurance
Before cleanup, take photos and a short video of the damage and the source. It’s a small step that makes any insurance claim much smoother. We can also document the cause and the repair for your records.

Where is my home’s main water shut-off valve?
In most North Texas homes it’s near the front where the line enters — a ground box by the street, in the garage, or near an outdoor hose bib. Turn it clockwise to close. Locate it now, before an emergency.
Should I turn off my water heater in a plumbing emergency?
If the heater is the source, or you’ve shut off the whole house, yes. Set a gas unit to “pilot” or off; flip the breaker for an electric unit, so it doesn’t run dry and get damaged.
What is considered a plumbing emergency?
Any situation where water is actively damaging your property or you’ve lost essential plumbing — a burst or badly leaking pipe, a sewer backup, an unstoppable overflowing toilet, a heavily leaking water heater, or no water at all.
Keep this list somewhere you can find it, and locate your main shut-off today. When something does go wrong, those two minutes of preparation are the difference between a quick fix and a flooded floor.
