What to Do When a Pipe Bursts: Atlanta Plumber’s Guide

A burst pipe can send gallons of water into your walls, floors, and ceilings in minutes. What you do first matters most. Here is the step-by-step plan our licensed Atlanta plumbers give homeowners, plus how to keep it from happening again.

Step 1: Shut Off Your Main Water Supply

Stopping the water is the single most important thing you can do. Every minute the pipe keeps flowing adds to the damage.

Where to Find the Main Shutoff Valve

• Inside the house: Look where the water line enters your home. In many Atlanta homes that is a basement wall, a crawl space, a utility room, the garage, or near the water heater.
• At the street: Many homes also have a shutoff at the water meter box near the curb. It often needs a meter key or a wrench to turn.
• Fixture valves: If the leak is at a single sink or toilet, the small valve under that fixture may be enough to stop it.

Turn a round gate valve clockwise until it stops. For a lever-style ball valve, turn the handle so it sits across the pipe. If the valve will not budge, do not force it hard enough to break it. Call a plumber and keep working on the steps below.

Tip: Find your main shutoff today, before you need it. Make sure everyone in your home knows where it is.

Step 2: Keep Everyone Safe from Water and Electricity

Water and electricity are a dangerous mix. If water is near outlets, cords, appliances, or your electrical panel, stay out of the wet area. Only turn off power at the breaker if you can reach the panel while standing on a dry floor. If you can’t do that safely, leave the area and call a professional.

• Stay out of rooms where the ceiling is sagging or dripping heavily. A soaked ceiling can come down.
• Keep kids and pets away from standing water.
• If you have a gas water heater or furnace in a flooded area and you smell gas, leave the home right away. Call 911 and your gas utility’s emergency line from outside.

Step 3: Drain the System and Relieve Pressure

Once the main is off, open a cold water faucet at the lowest point in the house, like a basement sink or an outdoor spigot. Then open a faucet on the top floor. This drains the water still sitting in the pipes and takes pressure off the broken section. Flush toilets once to empty the tanks.

If your water heater sits in the affected area, turn off its power or set a gas unit to “pilot” or “off” as the manufacturer’s label directs. Our water heater team can check it once the pipe is fixed.

Step 4: Limit the Water Damage

• Move furniture, rugs, electronics, and boxes out of the wet area.
• Mop, towel, or wet-vac standing water as soon as it is safe.
• Open windows and run fans to start drying. Wet drywall and insulation can grow mold if they stay damp.
• Take clear photos and videos of the damage and the broken pipe for your insurance company.
• Save receipts for any cleanup supplies or services.

Step 5: Call a Licensed Plumber

A burst pipe needs a proper repair, not just tape. Call our 24/7 emergency plumbing line at (678) 330-8439. We answer day or night, and same-day service is often available.

When we arrive, we find exactly where and why the pipe failed. Some breaks are easy to see. Others are hidden in a wall or under a slab. In those cases, our leak detection service helps us locate the problem without tearing out more than needed. Then we give you clear, upfront pricing for the fix before any work starts. Our pipe repair work covers copper, PEX, and PVC lines.

Why Pipes Burst in Atlanta Homes

Knowing the cause helps you prevent the next one. These are the most common reasons we see:

Winter Freezes

Atlanta winters are mild most of the time, but hard freezes do happen. Water expands when it freezes, which puts great pressure on the pipe. Pipes in crawl spaces, attics, garages, and exterior walls are most at risk. Often the break shows up when the ice thaws and water starts flowing again.

Aging or Corroded Pipes

Many Atlanta homes have older plumbing. Galvanized steel can rust from the inside out. Older copper can develop pinholes. Weak spots eventually give way.

High Water Pressure

Pressure that is too high strains every pipe, joint, and fixture. A pressure-reducing valve (PRV) keeps it in a safe range. If your PRV is missing or failing, a plumber can test and replace it.

Physical Damage and Shifting Soil

Nails or screws driven into a wall, settling foundations, and Georgia red clay that swells and shrinks can all stress pipes over time.

How to Prevent Your Next Burst Pipe

• Insulate pipes in crawl spaces, attics, and garages.
• On freezing nights, let faucets on outside walls drip and open the cabinet doors under sinks.
• Disconnect garden hoses in the fall and cover outdoor spigots.
• Keep your home heated, even when you travel in winter.
• Have your water pressure checked, especially if you hear banging pipes.
• Fix small leaks early. They can signal a pipe that is wearing out.

Burst Pipe FAQs

Should I turn off my water heater if a pipe bursts?

If the water heater is in the flooded area or you have shut off the main supply for a long time, it is a good idea. Turn off the breaker for an electric unit only if you can reach the panel from a dry spot. Set a gas unit to its off or pilot setting per the label. If you smell gas, leave and call 911 and your gas utility from outside.

Can I fix a burst pipe myself?

A temporary patch or repair clamp may slow a leak, but it is not a permanent fix. A burst pipe often points to a bigger issue, like freezing, corrosion, or high water pressure. A licensed plumber can repair the damaged section properly, check for other weak spots, and test the system before turning your water back on.

How do I know if a pipe burst inside a wall?

Watch for water stains, bubbling paint, damp or soft drywall, a musty smell, a sudden drop in water pressure, or a water meter that keeps moving when all fixtures are off. Any of these can point to a hidden leak. Our leak detection service can help find the source so we open only what is needed.
