Signs You Need Emergency Plumbing Repair

ProCraft Editorial Team ·

Most plumbing problems can be scheduled during normal business hours. A slow drain, a running toilet, low water pressure — these are annoying but not urgent. But some plumbing situations demand immediate action, and waiting even a few hours can mean the difference between a $400 repair and a $15,000 water damage restoration.

Here’s how to tell which category your problem falls into.


Call an Emergency Plumber Right Now If You See:

1. A Burst or Actively Leaking Pipe

Water spraying from a pipe or pooling rapidly anywhere in your home is an emergency. First step: shut off your main water supply valve (usually in the basement, utility room, or near your water meter). Then call a plumber immediately.

Every minute counts. At just 1/8” in diameter, a burst pipe can discharge 250 gallons per hour.

2. Sewage Backup

If multiple drains are backing up simultaneously — floor drains, toilets, tubs — your main sewer line is likely blocked or damaged. Raw sewage contains pathogens that pose serious health risks. Do not use any water in the home until a plumber clears the line.

Warning signs of main line blockage:

3. No Hot Water (Gas Water Heater)

A gas water heater that suddenly stops producing hot water may have a failed pilot, a faulty thermocouple, or — in rare cases — a gas leak. If you smell gas near your water heater, leave the building immediately and call your gas utility. Do not use light switches or open flames.

4. Visible Water Damage or Wet Drywall

Water stains spreading across ceilings or walls indicate an active leak inside your structure. The longer water sits in your walls, the greater the mold risk. Emergency plumbing service is warranted even if you can’t find the source.

5. Frozen Pipes

In sub-freezing weather, if you turn on a faucet and nothing comes out, a pipe may be frozen — and could be on the verge of bursting. Call a plumber before applying heat. Thawing a pipe incorrectly can crack it.


Problems That Can Usually Wait (But Schedule Soon)

SymptomUrgency
Dripping faucetLow — schedule within a week
Running toiletLow-medium — wastes water, schedule within days
Slow single drainLow — often a DIY fix
Low water pressureMedium — diagnose source first
Water heater over 12 years oldMedium — get a pre-failure inspection

What to Do While Waiting for the Plumber

  1. Shut off water at the source — fixture shutoff valve or main supply.
  2. Open a cold faucet downstream to relieve pressure.
  3. Move valuables away from any wet area.
  4. Document with photos for insurance.
  5. Bail or shop-vac standing water — mold growth begins within 24–48 hours.
