The Most Common Plumbing Emergencies (And What to Do Before the Plumber Arrives)
When a plumbing disaster strikes, panic is the last thing you need. The key is knowing exactly what to do before help arrives. At In A Flash Heating & Plumbing, we’ve seen it all—so here’s your guide to the most common plumbing emergencies and the immediate steps you can take to minimize damage until a pro is on the way.
1. Burst or Leaking Pipes
The Problem: A frozen, corroded, or damaged pipe can rupture suddenly, causing massive water damage.
What to Do:
Immediately shut off your home’s main water supply (usually in the basement, near the water meter).
Turn on nearby faucets to drain excess water from the system.
If safe, place a bucket under the leak to catch water and prevent further damage.
Call us ASAP at 781-572-2575 for emergency service.
2. No Hot Water
The Problem: Waking up to an ice-cold shower? Your water heater could have failed due to sediment buildup, thermostat issues, or a mechanical fault.
What to Do:
Check if the water heater’s pilot light (gas) or breaker (electric) is still on.
Avoid tinkering with gas lines—if you smell gas, evacuate and call your utility company.
If water is leaking from the heater, shut off the water supply to the tank.
Contact our team for fast water heater repairs or replacements.
3. Overflowing Toilet
The Problem: A stubborn clog or faulty float mechanism can turn a bathroom into a flood zone in minutes.
What to Do:
Remove the toilet tank lid and push the flapper down to stop water from flowing into the bowl.
Turn the water shut-off valve behind the toilet clockwise to stop the supply.
Use a plunger if the clog is visible and minor.
If it keeps happening, you may have a deeper clog that needs professional clearing.
4. Sewer Line Backup
The Problem: Multiple drains are slow or clogged, and you notice foul odors or water backing up into sinks, tubs, or toilets.
What to Do:
Stop using all water in your home immediately.
Avoid using chemical drain cleaners—they can make the situation worse.
If sewage is entering the home, block off the area to prevent contact and contamination.
Call us immediately for emergency sewer service.
5. Gas Leaks (Heating-Related)
The Problem: Gas-powered boilers, furnaces, and water heaters can develop leaks—posing serious safety risks.
What to Do:
Evacuate your home immediately.
Do not use electrical switches, lighters, or open flames.
Call your gas company or 911 right away.
Once the area is safe, our licensed technicians can repair or replace the faulty equipment.
Be Prepared Before It Happens
A plumbing emergency can strike at any time, but being prepared makes all the difference.
Know where your main water shut-off valve is located.
