What to Do When a Pipe Bursts: Emergency Steps That Save Thousands

A burst pipe is one of the most stressful things that can happen in a home. Water is moving fast, the damage is visible and growing, and most people freeze because they don’t know what to do first. The decisions you make in the first 10–15 minutes have an enormous impact on the total damage — the difference between a few hundred dollars and a full gut job. If you want to understand how to reduce the risk before winter hits, our guide on preventing frozen pipes in Utah’s mountain communities covers the steps that actually work.

I’ve responded to hundreds of burst pipe calls across Utah County and Salt Lake County. Here is the exact sequence of steps that limits damage and keeps you on the right side of your insurance claim.

Step 1: Shut Off the Water — Immediately

This is the only thing that matters right now. Everything else waits.

Locate your main water shutoff valve. In most Utah homes, it’s in one of these places:

• The basement or mechanical room, near where the main water line enters the house
• An exterior wall on the side of the house facing the street
• In a utility closet near the water heater

Turn it clockwise until it stops. If it’s a ball valve (lever handle), rotate it 90 degrees so it’s perpendicular to the pipe. If you’ve never located this valve, do it today — before you need it.

If you can’t find the main shutoff, the water meter itself usually has a shutoff valve in the meter box in your yard near the street. You may need a meter key or a flathead screwdriver to operate it.

Don’t spend more than 60 seconds searching. If you can’t find the shutoff fast, have someone call the water utility while you keep looking.

Step 2: Turn Off Your Water Heater

Once the main water is off, shut down your water heater — either the gas supply valve behind the unit or the circuit breaker for electric. Running a water heater without water in the tank can burn out the heating elements or, on gas units, damage the heat exchanger.

This takes 30 seconds and protects a $900–$1,500 appliance.

Step 3: Relieve Pressure and Drain the Lines

Open the lowest faucet in the house — a basement utility sink, a hose bib, or a bathtub faucet on the ground floor. This drains water that’s still sitting in the pipes and relieves any residual pressure that could be pushing water toward the break.

Open a few other faucets around the house as well. The goal is to get as much water out of the pipe system as possible before you start dealing with the damage.

Step 4: Stop the Immediate Flow if You Can

If you can safely access the burst section — meaning it’s not inside a wall or ceiling cavity — there are temporary measures that slow or stop flow while you get a plumber on the way.

• Pipe repair clamps (sold at any hardware store) can stop a crack or pinhole leak in a straight pipe section
• Self-fusing silicone tape wrapped tightly around a crack provides short-term sealing
• A rubber patch held in place with a C-clamp and wooden blocks works in a pinch

These are not repairs. They’re temporary stabilizers. Get a licensed plumber for the actual fix.

If the burst is inside a wall and you can hear or see water spreading, your priority shifts to step 5.

Step 5: Document Everything Before You Clean Up

Call your homeowner’s insurance company, but before you mop up a single drop: photograph and video everything. The standing water, the damaged pipe, the affected flooring, drywall, furniture, personal items — all of it.

Insurance adjusters need documentation of the damage as it occurred. Cleaning up before documenting can significantly reduce your claim or give the adjuster grounds to dispute coverage.

Take photos from multiple angles. Note the time. This takes five minutes and can be worth thousands of dollars.

Step 6: Remove Standing Water and Begin Drying

Now you can start cleanup. Standing water causes mold growth within 24–48 hours. The faster you get it out, the less secondary damage you’ll deal with.

• Wet/dry shop vac for standing water
• Towels and mops for residual moisture
• Box fans and dehumidifiers to begin drying immediately

If water has gotten into walls or under flooring, surface drying isn’t enough. Professional water mitigation companies have moisture meters and commercial drying equipment that can reach areas you can’t see. Your insurance policy typically covers this.

When to Call 911 vs. a Plumber

Call 911 if:

• The water is near an electrical panel, outlets, or appliances that are still powered
• You smell gas (evacuate first, then call)
• The structural integrity of floors or ceilings is in question

For everything else — including major flooding with no electrical or gas risk — call a licensed plumber. Our emergency plumbing services are available 24/7, and we can typically be on site within an hour in most of our service area.

Why Burst Pipes Are More Common in Utah Than People Expect

Utah’s winters create specific pipe burst risks that don’t apply everywhere.

Freeze-Thaw Cycles

Utah gets cold, but it also warms up quickly. The Wasatch Front can go from 5°F overnight to 45°F by afternoon. This freeze-thaw cycle — particularly in early spring and late fall — stresses pipe connections and accelerates existing cracks.

Vulnerable Locations in Utah Homes

• Garage walls with water supply lines and no insulation on the exterior side
• Crawl spaces in older homes in communities like Provo, American Fork, and Murray, where venting was common and insulation was minimal
• Exterior hose bibs that weren’t winterized in the fall
• Vacation and investment properties left at low heat (or no heat) over a cold weekend

When Pipes Don’t Freeze — They Burst Later

A pipe that freezes doesn’t always burst immediately. Sometimes the ice creates a crack that holds under pressure until the water thaws and flow resumes. You turn the heat back on after a cold weekend, the ice melts, and 45 minutes later you have water running through your ceiling. The freeze happened days ago — the burst happens now.

Prevention: What to Do Before Winter

• Insulate exposed pipes in unheated spaces — foam pipe insulation is inexpensive and effective
• Disconnect and drain garden hoses before the first hard freeze
• Shut off and drain exterior hose bibs using the interior shutoff valve if your bibs are older models
• Keep interior temperature above 55°F if you’re leaving for more than a day in winter
• Know where your main shutoff is — today, not during an emergency
