Stay Calm, Move Fast, and Know These Steps — They Could Save You Thousands
A plumbing emergency doesn’t announce itself in advance. It happens at 11 p.m. on a Tuesday, or on a Sunday morning before anyone’s had coffee, or in the middle of a Chicago winter when pipes that have been under stress for months finally give out. One minute everything is fine. The next, water is going somewhere it absolutely shouldn’t be.
According to the Insurance Information Institute, about 1 in 67 insured homes files a water damage or freezing claim every year — making it the second most common type of homeowners insurance claim in the country. The average payout on those claims is nearly $14,000. What most homeowners don’t realize is that the difference between a manageable repair and a catastrophic one often comes down to what you do in the first ten minutes.
This guide walks you through exactly what to do when a plumbing emergency hits — before the plumber arrives, while you’re waiting, and how to protect yourself throughout the process.
Step 1: Shut Off the Water Immediately
This is the single most important action you can take and the one most homeowners hesitate on because they’re not sure where the shutoff is. Find it now — before you ever need it.
Your main water shutoff valve is typically located in the basement near where the water line enters the home, in a utility room, or near the water meter. In Chicago and many older suburban homes, it’s often along the front foundation wall. It may be a gate valve that requires multiple turns or a ball valve with a lever handle that shuts off with a quarter turn.
If the emergency is isolated to one fixture — a toilet that won’t stop running, a supply line under the sink that’s spraying — there’s usually a local shutoff valve right at the fixture. Turn that first. If you can’t find it or it doesn’t work, go straight to the main.
Every adult in your household should know where the main shutoff is and how to operate it. If you’re a Chicagoland homeowner who has never located yours, do it today. The five minutes it takes could save you tens of thousands of dollars someday.
Step 2: Turn Off Your Water Heater
Once the main water supply is off, your next step is to turn off your water heater. This is a step many homeowners skip and later regret. With no water flowing into the tank, a water heater that continues running can overheat, build pressure, and in extreme cases fail dangerously.
For a gas water heater, turn the control knob to the “pilot” setting. For an electric unit, switch off the circuit breaker for the water heater at your electrical panel. This takes thirty seconds and eliminates a secondary problem from compounding your primary one.
Step 3: Address the Electricity if Water Is Involved
Water and electricity are a lethal combination, and in a flooding situation this risk is real. If water is spreading near outlets, appliances, or your electrical panel — or if you have any doubt about whether electrical components have been compromised — shut off power to the affected area of your home at the breaker panel.
If there is standing water between you and the electrical panel, do not walk through it to reach it. Exit the area and call 911. No repair is worth electrocution.
Step 4: Drain the System
After the main water supply is off, open the cold water faucets throughout your home and flush the toilets. This drains the remaining water out of the pipes, relieves pressure in the system, and reduces the volume of water that can continue leaking from the damaged area. It takes only a few minutes and meaningfully reduces ongoing damage while you wait for help.
Step 5: Start Containing and Documenting the Damage
While the water supply is off and you’re waiting for your plumber, do two things simultaneously — contain the mess and document everything.
For containment, use towels, buckets, and mops to remove standing water from floors as quickly as possible. Move electronics, furniture, and valuables out of the affected area or elevate them. Every minute water sits on hardwood floors, drywall, or subfloor materials is damage accumulating. If you have a wet/dry shop vacuum, use it. Open windows if weather permits to begin drying the space.
For documentation, take photos and video of everything — the source of the problem, every affected room, damaged belongings, wet walls, soaked flooring. Do this before you clean anything up. Your insurance company will need this evidence, and as Progressive notes in their guidance on burst pipe claims, homeowners insurance typically covers sudden and accidental water damage — but you’ll need clear documentation to support the claim. Start that paper trail immediately.
Step 6: Call a 24/7 Licensed Plumber
Now that you’ve stopped the bleeding and documented the damage, call a licensed emergency plumber. Don’t wait until morning if it’s the middle of the night — a plumbing emergency that’s left unaddressed overnight almost always results in significantly more damage and a significantly larger bill.
When you call, be ready to tell them the location of the problem, what type of emergency it is, whether you’ve been able to shut off the water, and whether electricity is a concern. The more information you give, the faster and better prepared your plumber arrives.

What Counts as a Plumbing Emergency?
Not every plumbing problem needs a midnight service call — but some absolutely do. Knowing the difference helps you respond appropriately and avoid both under-reacting to a serious situation and over-paying for a non-urgent one.
These are plumbing emergencies — call immediately:
A burst or actively leaking pipe with water flowing into your home. Sewage backing up into the house through floor drains, bathtubs, or toilets. No water at all coming into the home. A gas line issue — smell of gas near appliances or pipes (leave the home immediately and call 911 first, then your gas company). A water heater that is leaking, making loud rumbling or popping sounds, or has water pooling around its base. Flooding in the basement from any plumbing source.
These can typically wait until business hours:
A single slow-draining sink or shower with no backup. A running toilet that is otherwise functional. Low water pressure at one fixture. A dripping faucet. A minor leak under a sink that you can contain with a bucket.
When in doubt, call. The cost of a late-night service call is almost always less than the cost of water damage that develops while you wait.
Chicago-Specific Plumbing Emergencies to Know
Chicago homeowners face a specific set of plumbing emergencies that homeowners in other parts of the country may not. Burst pipes from freeze events are a seasonal reality — when a polar vortex drops temperatures to dangerous lows, pipes in uninsulated spaces, exterior walls, and unconditioned areas of the home are at serious risk. If you wake up to no water during or after a major cold snap, assume a frozen or burst pipe until proven otherwise and call immediately. Our emergency burst pipe repair for Chicago homeowners is specifically designed for the kind of freeze-related pipe failures that Chicago winters produce.
Sewer backups are another Chicago-specific emergency that catches homeowners off guard. The city’s aging combined sewer system, heavy clay soil, and mature tree root systems create conditions where sewer laterals crack, shift, and get infiltrated over time. When a backup happens, sewage comes up through the lowest drains in the home — typically basement floor drains or bathtubs — and it escalates fast. This is a health hazard that requires immediate professional attention, not a wait-and-see situation.
If your home doesn’t have a flood control system for Chicago and suburban homes — specifically backflow prevention or an overhead sewer — and you’ve experienced recurring basement flooding or sewer backups, a plumbing emergency is eventually a matter of when, not if. That’s a conversation worth having before the next emergency, not after.
After the Plumber Leaves: What to Do Next
Getting the emergency fixed is step one. What you do in the hours and days afterward determines how well your home recovers and whether your insurance claim goes smoothly.
Keep all receipts and invoices from the service call. Contact your homeowners insurance company promptly — most policies require you to report damage in a timely manner, and delays can complicate claims. Ask your insurance agent specifically whether the damage is covered and what documentation they need.
Ensure the affected area is thoroughly dried — mold can begin developing within 24 to 48 hours of water exposure. If the damage was significant, a professional water damage restoration company may be necessary to dry walls, flooring, and structural components properly.
Finally, ask your plumber what caused the emergency and whether there are preventive measures that would reduce the risk of a recurrence. A whole-home residential plumbing inspection in Chicagoland after a significant emergency is one of the smartest investments a homeowner can make — it identifies other vulnerabilities before they become the next 2 a.m. phone call.
Frequently Asked Questions: Plumbing Emergencies in Chicago
Where is my main water shutoff valve in a Chicago home?
In most Chicago-area homes it’s in the basement, along the front foundation wall near where the water supply line enters from the street. In some homes it’s near the water meter or in a utility room. If you genuinely can’t find it, call a plumber during business hours to locate and label it — that knowledge is invaluable in an emergency.
What if I can’t shut off the water myself?
Call an emergency plumber immediately and tell them you cannot shut off the water. Some main shutoffs — particularly in older Chicago properties — require a special curb key tool to access the valve at the street. A licensed plumber will have the equipment to shut off the water at the curb if the interior valve can’t be operated.
Will my homeowners insurance cover a burst pipe?
In most cases, yes — homeowners insurance typically covers sudden and accidental water damage from burst pipes. What it generally does not cover is damage resulting from neglect, a slow leak that went unreported, or lack of maintenance. Document everything immediately, call your insurer promptly, and keep all repair receipts. Every policy is different so read yours carefully and ask your agent specific questions.
How long will I be without water after a plumbing emergency?
It depends entirely on the nature and location of the problem. An isolated pipe repair may restore water service within a few hours. A main line issue or sewer lateral problem can take longer depending on the extent of the damage and any required permits. Your plumber should be able to give you a realistic timeline once they’ve assessed the situation.
Is a running toilet a plumbing emergency?
Generally not — a running toilet is wasteful but not immediately damaging in most cases. It can usually wait until business hours unless it’s causing overflow or flooding. A toilet that is actively overflowing with no sign of stopping is a different situation entirely — shut off the local supply valve behind the toilet immediately and call for help.
What should I do if I smell gas near my plumbing?
Leave the home immediately without operating any switches, appliances, or anything that could create a spark. Call 911 from outside, then call Peoples Gas or your gas utility’s emergency line. Do not re-enter until cleared by emergency responders. A gas leak is not a plumbing call — it’s a 911 call first.
