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

A leaking water heater can go from small drip to full tank failure.

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

One clogged toilet that stops after plunging may not be an emergency.

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.
