What to Do When a Pipe Bursts in Your Utah Home

By Court Lundberg · July 9, 2026

A burst pipe is one of those home emergencies that doesn’t give you time to think. Water is going somewhere it shouldn’t, it’s going fast, and every minute matters. Knowing what to do before it happens is the difference between a manageable repair and tens of thousands of dollars in water damage.

Here’s a clear sequence of steps to follow, and what to expect once you’ve got things under control.

Step 1: Shut Off the Water Immediately

Your first move is always the main water shutoff. Not the valve under the sink. Not the valve behind the toilet. The main shutoff, which controls all water flowing into your home.

If you don’t know where yours is, find it now, before you ever need it. I tell every homeowner this, and I mean every adult in the house, not just one person. When water is moving at 2am, the last thing you want is to be hunting for a valve you’ve never touched. In most Utah homes, the main shutoff is in one of three places: near the water meter outside (usually near the street or sidewalk in a covered box), in the utility room or mechanical room, or near the foundation where the main supply line enters the house.

The shutoff valve is typically a gate valve (round handle) or a ball valve (lever handle). Turn a gate valve clockwise until it stops. Flip a ball valve 90 degrees so the lever is perpendicular to the pipe. Water supply to the whole house will stop.

Once the main is off, open the lowest cold tap in your house (a hose bib outside works well) to drain the pressure still sitting in the lines. This releases residual water that would otherwise continue draining from the break.

Step 2: Turn Off the Water Heater

With the main supply cut off, your water heater is no longer getting the cold water it needs to operate safely. Turn it off at the unit itself to prevent the heating element from running dry, which can damage it.

For a gas heater, turn the thermostat dial to the “pilot” setting. For an electric heater, switch off the breaker at your electrical panel. This only takes a minute and protects a piece of equipment that costs $800 to $3,000 to replace.

Step 3: Turn Off the Electricity in Affected Areas

If water is anywhere near electrical outlets, panels, or fixtures, cut power to those areas at the breaker box before you touch anything. Water and electricity are a dangerous combination. If you’re not sure which breakers cover the affected area, turn off the main breaker to the whole house.

Don’t re-energize those circuits until a licensed professional confirms the area is dry and safe.

Step 4: Start Removing Water

Every minute water sits on your floors, walls, and subfloor does more damage. Get it moving immediately.

Use whatever you have on hand. Towels for small amounts. A wet/dry vacuum if you have one. Buckets and mops. If water has pooled significantly, a submersible pump will move it much faster. Hardware stores like Home Depot and Lowe’s in Salt Lake and Utah County carry or rent them.

Open windows and doors if the weather allows, and turn on any fans in the affected area to start the drying process. The faster you reduce moisture, the lower your chances of mold developing in the following days.

Step 5: Document Everything Before You Clean Up

Before you start pulling up wet carpet or drying out walls, take photos and video of everything. Document the source of the break if you can see it, the path of water spread, the extent of the damage to floors, walls, cabinets, and any belongings.

Your homeowner’s insurance policy almost certainly covers sudden and accidental water damage from a burst pipe. The documentation you create in the first hour is what supports that claim. Don’t skip this step.

Step 6: Call a Plumber

Once the immediate emergency is managed, you need a plumber to find and fix the source of the break. Don’t try to assess or repair the pipe yourself unless you have real plumbing experience. What looks like a small crack at one location can indicate a larger problem in that section of pipe, especially in homes with older copper or galvanized steel lines.

A plumber will locate the failure, assess whether it’s an isolated break or a sign of wider pipe deterioration, and give you repair options. In some cases the right fix is a section repair. In others, especially older Utah homes with corroded galvanized pipes, whole-home repiping is the more practical and durable answer.

If you are standing in it right now, call us at 385-449-0144. We answer around the clock, we will talk you through the shutoff on the phone while you wait, and we will give you a 2-hour arrival window rather than a vague all-day promise. If the water is already off and it can wait for business hours, book online instead.

Why Pipes Burst in Utah

Understanding the cause helps prevent a repeat.

Freezing. Utah winters get cold enough to freeze pipes, particularly in uninsulated exterior walls, crawl spaces, garages, and attic spaces. Water expands when it freezes. A pipe that can’t accommodate that expansion fails. This is one of the most common causes of burst pipes in Utah County and Salt Lake County homes during cold snaps.

Age and corrosion. Galvanized steel pipes, common in Utah homes built before the 1980s, corrode from the inside out. Hard water accelerates that process. A pipe that looks intact from the outside can be paper-thin on the inside and fail under normal water pressure. If your home has galvanized pipes and you haven’t had them assessed, this is worth doing.

Hard water scale. Mineral scale doesn’t just narrow pipes, it creates localized pressure points. In some cases, scale buildup contributes to pipe failure by restricting flow and increasing stress at specific spots.

High water pressure. Water pressure above 80 psi puts excess stress on pipes, joints, and fixtures throughout your home. A pressure reducing valve (PRV) regulates incoming pressure to a safe range. If yours is failing or was never installed, your pipes are under more stress than they should be.

Preventing the Next One

After the repair is done and the dust settles, it’s worth having a plumber assess why the pipe failed and whether there are other vulnerabilities in your system. A few things to ask about:

Insulate exposed pipes. Any pipe in an unheated space, including garage walls, crawl spaces, and exterior-facing walls, should have foam pipe insulation. It’s inexpensive and takes minutes to install.

Know your main shutoff. Every adult in your household should know where the main shutoff is and how to operate it. A 10-second introduction now is worth a lot during a 2am emergency.

Check your water pressure. If you don’t know your home’s water pressure, a plumber can check it quickly. If it’s above 80 psi, installing or replacing a PRV is a straightforward fix.

Consider a smart water shutoff. This is the one I tell people about most, because it saved my own home. I have a Moen Flow installed right after my main shutoff. It hooks to Wi-Fi, watches your water usage, and if it sees something abnormal, like a pipe letting go while nobody is home, it shuts the water off automatically. I also keep leak pucks on the floor by the dishwasher and the other spots that tend to flood. The moment one of those gets wet, the water shuts off. Installed, it runs about $1,500.

That sounds like a lot until it earns its keep. It has stopped two floods in my house already, and one of them was my own water heater. I am a plumber. I know you are supposed to replace a water heater around the 10-year mark. But I am also human, I let mine go past it, and it went out. The Moen Flow caught it before it ruined my basement. So yes, I install these for customers, and yes, I run one myself.
