Have a Plumbing Emergency? Here's What to Do for Burst Pipes and Water Heater Repair

In a plumbing emergency, shut off the main water valve, cut electricity near standing water, and call a plumber. What happens in the minutes that follow determines how much damage gets done.

This guide covers burst pipes, water heater failures, sewer backups, and everything in between, including the preparation steps that change the outcome before a crisis even starts.

What Counts as a Plumbing Emergency?

A plumbing emergency is any situation that is actively causing water damage, poses a health or safety risk, or has left the property without usable water. The following situations require an immediate call to an emergency plumber:

• Burst or actively leaking pipes
• Sewer backup or sewage inside the home
• Overflowing toilet that cannot be stopped
• Gas line smell near plumbing fixtures
• Frozen pipes at risk of bursting
• Basement flooding
• Sump pump failure during a storm or power outage
• Broken washing machine hose causing flooding
• Complete loss of water pressure or water supply
• The water heater is actively leaking or failing

Not every plumbing problem requires an emergency call.

A single slow drain, a dripping faucet, a running toilet, or low water pressure at one fixture are all worth addressing, but can wait for a scheduled visit during regular business hours.

When in doubt, call. A plumbing problem that seems minor can escalate quickly, and an emergency plumber can assess the situation and advise whether it requires immediate attention or can be scheduled.

What to Do When a Pipe Bursts?

A burst pipe gives you very little time before water spreads into walls, floors, and ceilings. Knowing the right steps before it happens is what keeps a bad situation from becoming a catastrophic one.

Step 1: Shut off the main water supply valve

The main water supply valve stops all water flow into the property. In most homes, it is located near the water meter, in the basement, in a utility room, or on an exterior wall. Turn it clockwise to close it. Every adult in the household should know its location before a crisis happens.

Step 2: Turn off the electricity near the standing water

Cut power to the affected area at the breaker before touching anything if water is pooling near electrical outlets, appliances, or your breaker panel. Do not enter a flooded room if electricity has not been confirmed off.

Step 3: Open all faucets to drain the system

Turn on all hot and cold faucets throughout the property after shutting off the main valve. This drains remaining water from the pipes and relieves pressure buildup, reducing the volume of water that continues to flow from the burst point.

Step 4: Contain the water

Use towels, buckets, or a wet/dry vacuum to remove standing water and slow the spread. Move furniture, electronics, and valuables out of the affected area before water reaches them.

Step 5: Apply a temporary fix while waiting

A temporary patch slows an active drip while you wait for a burst pipe plumber to arrive. It is not a permanent repair. Options include:

• Pipe repair tape: wraps around the leak point to slow seeping on accessible straight sections.
• Pipe clamp: a metal clamp with a rubber gasket that compresses over the leak.
• Rubber patch and hose clamp: effective on accessible straight pipe sections.
• Epoxy putty: plugs small holes in accessible pipe sections and sets quickly.

A pipe that has been patched still requires a full professional assessment to determine why it failed and whether surrounding sections are at risk.

Step 6: Document the damage for insurance

Take photos and video of the burst pipe, the affected area, and any damaged property before cleanup begins. Keep all receipts for emergency repairs and water damage restoration.

Contact your insurance provider as soon as possible. Most homeowner policies cover sudden and accidental water damage, and early notification speeds up the claims process.

Step 7: Dry out the property

After standing water has been removed, use fans and dehumidifiers to increase ventilation and dry out affected walls, floors, and ceilings.

Mold begins to establish within 24 to 48 hours in wet conditions. If the water damage is extensive, Roto-Rooter's water cleanup service handles professional extraction, drying, and mold prevention alongside the plumbing repair.

Is a Broken Water Heater an Emergency?

Yes, in some cases. A water heater that is actively leaking, producing dangerous levels of heat, or showing signs of a gas or electrical hazard requires same-day water heater repair.

A unit that has simply stopped producing hot water without any of these warning signs is a disruption, but may not require an emergency call.

Signs your water heater is a plumbing emergency

Call an emergency plumber immediately if your water heater shows any of the following:

• An active leak from the tank body or supply connections
• The pressure relief valve is discharging water or steam
• Loud rumbling, banging, or popping sounds from inside the tank
• Rust-colored or discolored water at hot-only fixtures
• A gas smell near a gas-powered unit
• An electrical burning smell near an electric unit
• Water that is dangerously scalding and cannot be adjusted at the thermostat

A leaking tank can release significant water volume fast, causing the same kind of structural damage as a burst pipe.

A tripped pressure relief valve signals dangerous pressure buildup inside the tank. A gas or electrical smell near the unit is a safety hazard that requires immediate professional attention.

A note on rentals

In most jurisdictions across the United States, a lack of hot water in a rental property is legally considered an emergency that affects the habitability of the home.

In California, landlords are expected to restore hot water within 24 to 48 hours for essential service failures, for example. And, in Massachusetts, repairs affecting health and safety conditions generally must be addressed within 24 hours.

Requirements vary by state and municipality, but the consistent standard across most jurisdictions is that no hot water qualifies as an urgent repair requiring prompt action. Property managers and landlords should treat a water heater failure as requiring same-day attention regardless of whether the unit is actively leaking.

What to do when your water heater fails

Taking these steps immediately limits damage and prepares the property for the repair technician.

• For gas water heaters: Turn the gas supply valve to the off position and shut off the cold water supply valve on the pipe entering the top of the tank.
• For electric water heaters: Cut power at the breaker and shut off the cold water supply valve on the pipe entering the top of the tank.
• All water heater failures: Open hot water faucets throughout the property to relieve pressure in the lines. If the tank is actively leaking, contain standing water with towels or a wet/dry vacuum and call Roto-Rooter for water heater repair or replacement at ${marketPhone}.

Other Plumbing Emergencies and What to Do

Burst pipes and water heater failures are the most damaging plumbing emergencies, but they are not the only ones that require an immediate response.

These five situations each carry their own risks and call for a specific first action.

Overflowing toilet

Turn off the water supply valve at the base of the toilet immediately. Do not flush again. If the bowl is already full, do not plunge, as this can force water over the rim and cause a larger overflow.

Remove excess water from the bowl using a cup or small bucket, and put on rubber gloves before handling any water that may contain sewage. If a toilet snake does not clear the blockage, call Roto-Rooter.

A toilet that overflows repeatedly or cannot be cleared points to a deeper blockage in the drain line that requires professional equipment to resolve.

Sewer backup

Stop using all water in the property immediately, including sinks, toilets, showers, and appliances. Running water into a backed-up sewer line forces sewage further into the home. Sewer backups carry bacteria and pathogens that make the affected area a health hazard.

Do not attempt to clean up sewage without professional protective equipment. Call Roto-Rooter for emergency drain cleaning and, if sewage has entered the living space, water damage cleanup.

Sump pump failure

A sump pump that fails during a heavy storm or power outage allows groundwater to flood the basement rapidly. If the pump has failed due to a power outage, a battery backup unit can bridge the gap until power is restored. If the pump has failed mechanically, call Roto-Rooter immediately.

Remove valuables and electronics from the basement and cut electricity to the affected area before standing water makes entry unsafe.

Noisy pipes and water hammer

Banging, clanking, or hammering sounds from pipes are not just an annoyance. They indicate high water pressure surging through the line, which accelerates wear on pipe joints, fittings, and appliances throughout the property.

High pressure left unaddressed increases the risk of a joint failure or burst pipe. Check your water pressure using a basic gauge connected to an outdoor hose bib. Anything consistently above 60 pounds per square inch warrants a professional assessment. Call Roto-Rooter if the noise is sudden, severe, or accompanied by visible pipe movement.

Gas line smell

Exit the property immediately if you smell sulfur or rotten eggs near any plumbing fixture, appliance, or gas line. Do not switch any lights or appliances on or off on your way out. Call 911 and your gas utility company from outside the building.

Do not re-enter until emergency services have cleared the property. Gas line repair requires a licensed professional and is not a situation for any DIY attempt.

How to Prepare for a Plumbing Emergency Before One Happens

The difference between a minor repair and a major water damage event is often measured in minutes. Knowing where your shut-off valves are, having the right supplies on hand, and keeping Roto-Rooter's number saved are the three things that change the outcome of a plumbing emergency before it even starts.

Know where your main water shut-off valve is located. The main shut-off valve stops all water flow into the property. Find it now, confirm it operates correctly, and make sure every adult in the household knows where it is and how to use it.

Locate, label, and test individual fixture shut-off valves. Toilets, sinks, dishwashers, and washing machines all have individual shut-off valves. Label each one clearly so any household member can isolate a problem quickly without cutting water to the entire property. Closing the valve closest to the problem stops water flow to that fixture without interrupting service to the rest of the home.

Insulate exposed pipes before winter. Pipes running through unheated basements, crawl spaces, garages, and exterior walls are vulnerable to freezing. Foam pipe insulation is inexpensive, takes minutes to install, and prevents one of the most common causes of burst pipes.

Check your water pressure regularly. Extremely high water pressure accelerates wear on pipe joints, fittings, and appliances throughout the property. A basic pressure gauge connects to any outdoor hose bib and takes seconds to read. Normal household water pressure runs between 40 and 60 pounds per square inch. Anything consistently above that range warrants a professional assessment.

Inspect hoses and connections regularly. Washing machine supply hoses, dishwasher hoses, and refrigerator water lines are common sources of sudden flooding. Checking them for bulging, cracking, or rust at the fittings takes minutes and can prevent a significant water damage event.

Keep basic emergency supplies accessible. A wet/dry vacuum, pipe repair tape, a pipe clamp, towels, and a flashlight are the core items that make a meaningful difference in the first few minutes of a plumbing emergency.

Save Roto-Rooter's number before you need it. Having a trusted emergency plumber's contact saved before a crisis means faster response when every minute counts. Roto-Rooter is available 24/7, 365 days a year at ${marketPhone}.

Schedule annual plumbing inspections. A professional inspection identifies aging pipes, early-stage leaks, and failing components before they produce an emergency. Catching a problem early costs significantly less than responding to a failure.

FAQs About Plumbing Emergencies

What counts as a plumbing emergency?

A plumbing emergency is any situation that is actively causing water damage, poses a health or safety risk, or has left the property without usable water.

Burst pipes, sewer backups, overflowing toilets that cannot be stopped, gas line smells, frozen pipes at risk of bursting, basement flooding, sump pump failure, and a water heater that is actively leaking or showing safety hazards all qualify as emergencies requiring an immediate call to a plumber.

Is no hot water a plumbing emergency?

Not always. A complete loss of hot water without any active leaking, gas smell, or electrical hazard is a disruption but not a structural emergency. Calling after hours for a non-urgent water heater issue can significantly increase the cost of the service call.

However, for rental properties, most jurisdictions treat no hot water as a habitability emergency requiring same-day attention from the landlord.

When can a water heater wait for a scheduled visit instead of an emergency call?

If the unit shows inconsistent hot water temperature, a slightly reduced hot water supply, or minor rumbling sounds during heating cycles without any active leaking, gas smell, electrical hazard, or pressure relief valve discharge, schedule a water heater repair appointment rather than an emergency call.

Calling after hours for a non-urgent water heater issue can significantly increase the cost of the service call.

How much does a plumber charge to fix a busted pipe?

Burst pipe repair cost varies significantly depending on the pipe's location, material, and the extent of the damage. An accessible pipe under a sink or in an unfinished basement costs less to repair than one running behind a finished wall, under a concrete slab, or underground.

Emergency and after-hours calls carry additional surcharges on top of the standard repair cost. Water damage remediation, drywall repair, and mold prevention add further cost if the pipe was leaking for an extended period before being discovered.

A written assessment from a licensed plumbing company before work begins is the most reliable way to understand the full scope of cost for your specific situation.

Who is responsible for burst water pipes?

Responsibility depends on the property type and the cause of the burst.

For homeowners, the repair and any resulting water damage are typically the owner's responsibility, and most standard homeowner's insurance policies cover sudden and accidental pipe bursts.

For renters, the landlord is generally responsible for repairing pipes and structural damage caused by normal wear and tear. If the tenant caused the burst through negligence, such as failing to maintain heat during a freeze after being instructed to do so, the tenant may share or bear full responsibility.

In condominiums, responsibility depends on whether the pipe serves a single unit or common areas, governed by the association's declaration and bylaws. When in doubt, review your lease or policy and contact your insurance provider immediately after shutting off the water and calling a plumber.

Is it worth it to repair a water heater?

It depends on the age of the unit and the nature of the repair. A general rule of thumb is that if the repair cost exceeds 50% of the cost of a new unit and the water heater is more than half through its expected lifespan, replacement is the smarter long-term investment.

Minor repairs such as replacing a faulty thermostat, heating element, or pressure relief valve on a relatively new unit are almost always worth doing. A unit that is actively leaking from the tank body, has significant corrosion, or is already near the end of its service life is a stronger candidate for replacement than repair.

Roto-Rooter's plumbing technicians can assess whether repair or replacement makes more financial sense for your specific unit before any work begins.

What is the average life of a water heater?

Traditional tank water heaters last between 8 and 12 years on average with proper maintenance. Tankless water heaters last significantly longer, typically between 15 and 20 years, with well-maintained units reaching 25 years or more.

Regular maintenance, including annual flushing, anode rod inspection, and sediment removal, extends the life of both types. Hard water accelerates wear on both tank and tankless units by causing mineral buildup inside the system.

If your water heater is approaching or past its expected lifespan and showing signs of trouble, scheduling a professional assessment before a failure occurs costs significantly less than responding to an emergency.

Is it cheaper to call an emergency plumber at night?

No. Emergency and after-hours plumbing calls, including nights, weekends, and holidays, carry higher rates than standard daytime service. Many plumbing companies charge an additional surcharge on top of their standard rate for calls outside regular business hours.

If the plumbing problem can safely wait until regular business hours without causing further damage, scheduling a daytime visit costs less.

However, a burst pipe, active flooding, a gas smell, or any situation where waiting risks significant water damage or a safety hazard should be treated as an emergency, regardless of the time or the additional cost.
