Is That a Plumbing Emergency? When to Call Right Away

Written By Chase Slepak

Not every plumbing issue needs a middle of the night phone call—but some absolutely do. If you're unsure whether to wait until morning or call an emergency plumber now, this blog will help you decide.

Here’s how to know when it’s time to act fast—and when it can wait.

When It Is a Plumbing Emergency

1. Burst Pipe

A burst pipe can flood your home in minutes, damaging walls, flooring, and personal belongings. If you hear rushing water behind walls or see pooling where it shouldn't be—shut off your main water valve and call immediately.

2. Sewer Backups

If sewage is coming up through your drains or toilets, that’s a major health hazard. Don’t wait—this can expose your home to dangerous bacteria and major cleanup costs.

3. No Water at All

A total lack of water may signal a major break in your main line. If your neighbors still have water, you should call a plumber right away to investigate.

4. Overflowing Toilet (That Won’t Stop)

A single clogged toilet can usually wait—but if it’s actively overflowing and won’t respond to plunging, turn off the water to that toilet and call for help.

5. Gas Smells from Water Heater

If you smell gas near your water heater, it could indicate a gas leak. This is both a plumbing and safety emergency—exit your home and contact your utility company and plumber immediately.

6. Major Leaks That Can’t Be Stopped

If a pipe, fixture, or water heater is leaking uncontrollably and shutting off local valves doesn’t help—call an emergency plumber. Water damage happens fast and costs more the longer it continues.

When It Can Wait Until Morning

  • A slow-draining sink or tub

  • A minor faucet drip

  • A clogged toilet (if you have another working one)

  • Low water pressure (unless it drops to zero suddenly)

  • A noisy or inefficient water heater

If you can contain the issue, avoid water use in the affected area. If there’s no immediate damage or safety risk, you're usually safe to schedule a next-day visit.

What to Do Before the Plumber Arrives.

If you’re facing an emergency, here are some immediate steps you can take while waiting for the plumber:

  • Shut off the water – Use the local shut-off valve near the fixture or your home’s main shut-off.

  • Unplug electrical devices near any leaks or pooling water to avoid risk of shock.

  • Clear the area so the plumber can get to the issue quickly.

  • Take pictures of any damage in case you need to file an insurance claim.
