Plumbing problems never happen at a good time.
Water starts leaking.
The toilet overflows.
There’s no water in the house.
You ask yourself:
Is this an emergency plumbing issue? Or can it wait until tomorrow?
Knowing the difference protects your home and your wallet.
In this post, we’ll explain:
What counts as emergency plumbing
What can wait
How fast water damage spreads
What to do before the plumber arrives
If you’re in Lemont or the Chicago Southwest Suburbs and unsure what to do, this guide will help you decide.
What Is Considered Emergency Plumbing?
Emergency plumbing means:
Active water damage
Health risk
Safety risk
Complete loss of plumbing function
If water is actively causing damage or sewage is backing up, you need same-day service.
Let’s break down the most common situations.
1. Burst Pipes

A burst pipe is always an emergency.
Why?
Water can pour out fast
Drywall, flooring, and insulation soak quickly
Mold can begin forming within 24–48 hours
In winter, frozen pipes are common in Illinois. When they thaw, pressure builds and pipes split.
Call right away if:
Water is spraying
You see flooding
Ceilings are sagging
Water pressure suddenly drops
What to do immediately:
Shut off the main water valve
Turn off electricity in affected areas if safe
Remove valuables from wet areas
Call for emergency plumbing service
The longer water runs, the higher the repair cost.
2. Sewer Backups
Sewer backups are serious.
This is not just water — it’s contaminated wastewater.
Signs include:
Multiple drains backing up
Sewage coming from floor drains
Strong sewer odor
Gurgling toilets
This is a health hazard.
Bacteria and waste should never sit inside your home.
Call for emergency plumbing immediately.
Do not:
Run water
Flush toilets
Use sinks
This can push more sewage inside.
3. No Water in the House
If you suddenly have no water:
Ask yourself first:
Did the city shut it off?
Did a main valve get turned accidentally?
If neighbors have water and you don’t, it may be:
A main line break
A frozen pipe
A major supply issue
No water means you cannot:
Shower
Cook
Flush toilets
Wash hands
This qualifies as urgent service, especially in winter.
4. Water Heater Leaking
If the tank cracks, it can release 40–50 gallons at once.
Call same day if:
Water pools around the base
You see rust or corrosion
The pressure relief valve is constantly dripping
The tank makes loud popping sounds
If you ignore it, the tank can rupture.
5. Overflowing Toilets

But call right away if:
Water keeps rising
Multiple toilets back up
Sewage appears in the tub or shower
This often points to a main drain blockage.
That needs professional drain cleaning.
What Can Wait Until Regular Service?
Not every plumbing issue needs emergency plumbing.
Here’s what usually can wait 24–48 hours:
Slow drains (no backups)
Dripping faucets
Running toilet (no overflow)
Minor under-sink leak with no active spraying
Low water pressure
Still important — but not middle-of-the-night urgent.
If you’re unsure, take photos and call for advice.
How Fast Does Water Damage Spread?
Faster than most homeowners expect.
Within minutes:
Water spreads across floors
Carpet absorbs moisture
Within hours:
Drywall swells
Cabinets begin absorbing water
Wood flooring starts warping
Within 24–48 hours:
Mold growth can begin
The key factor is speed.
Stopping water quickly saves thousands in repairs.
What To Do Before the Plumber Arrives
If you’re dealing with emergency plumbing, act fast.
1. Shut Off Water
Find your main water valve.
In most homes, it’s:
In the basement
Near the water meter
Along the front wall of the house
Turn it clockwise to shut off.
2. Shut Off the Water Heater (If Leaking)
Turn off power (electric)
Shut off gas supply (gas heater)
Close the cold water valve on top
3. Avoid Using Fixtures
Do not:
Flush
Run sinks
Do laundry
Until the issue is diagnosed.
4. Document Damage
Take photos.
This helps with insurance claims.
When In Doubt — Call
Many homeowners wait too long.
They hope it stops.
They think it’s minor.
They delay.
Small leaks turn into:
Floor replacement
Cabinet replacement
Mold remediation
Insurance claims
If water is active, spreading, or contaminated — it’s emergency plumbing.
