Plumbing problems have a way of surfacing when we least expect them. One moment, everything’s working just fine—then suddenly, there’s water flooding the bathroom floor, the water heater’s making strange noises, or a pipe under the sink has burst.

While it’s always best to contact a licensed plumber during a plumbing emergency, knowing how to take action in those first few minutes can prevent further damage and keep you calm under pressure. Whether you’re waiting for an emergency plumber to arrive or deciding if the situation truly warrants urgent help, your response can make a big difference.

Here are five of the most common plumbing emergencies homeowners face, and what to do before the professionals take over.

1. Burst Pipe

The situation: You hear a loud pop or notice water gushing from behind a wall, beneath a cabinet, or along a ceiling. A pipe has likely burst due to freezing temperatures, pressure buildup, or age-related deterioration.

Immediate steps:

  • Turn off the main water supply immediately to stop water from continuing to flow. This is usually located near the water meter or where the main line enters your home.

  • Drain your faucets to relieve pressure in the remaining lines. Open both hot and cold taps.

  • Collect leaking water using buckets or towels to limit water damage to flooring, drywall, and possessions.

  • Avoid electrical hazards. If water is near any outlets or electrical systems, shut off power to the affected area at your breaker box.

A burst pipe is one of the fastest-moving plumbing issues, and contacting an emergency plumber quickly is critical. It also may lead to other concerns like mold or water damage if not resolved promptly.

2. Overflowing Toilet

The situation: You flush the toilet, and instead of swirling away, the water rises—fast. Overflow begins before you can stop it, and panic sets in.

Immediate steps:

  • Close the toilet’s shut-off valve. This is typically located behind the toilet at the base. Turning it clockwise stops the water flow.

  • Lift the lid on the tank and manually close the flapper to stop more water from entering the bowl if the valve is hard to reach.

  • Use towels or a mop to control spreading water. If it has already overflowed onto the floor, act fast to prevent damage to subflooring.

  • Avoid flushing again. It won’t fix the issue and may worsen it.

Overflowing toilets are commonly caused by blockages. If you can’t clear the clog with a plunger or auger, it’s time to call in a professional plumber.

3. Water Heater Leak or Failure

The situation: You notice puddling around your water heater, hear unusual rumbling or popping sounds, or suddenly lose all hot water. It could be a slow leak, a failed valve, or signs of full water heater failure.

Immediate steps:

  • Turn off the power supply to the heater. For electric units, use the circuit breaker. For gas heaters, switch the gas valve to the “off” position.

  • Shut off the cold water supply leading to the heater. This valve is usually located above the unit.

  • Inspect the leak location. A small trickle from a valve might be repairable, but larger leaks from the tank itself often signal the need for full water heater replacement.

  • Avoid using hot water until a plumber has assessed the issue.

When water heaters malfunction, they can leak, fail to heat, or even pose safety concerns. A licensed plumber in East Valley, AZ will determine if water heater installation or repair is the safest route.

4. Clogged Sink or Shower Drain

The situation: Water is backing up into your sink or shower, refusing to drain. In severe cases, multiple drains may clog at once—indicating a deeper issue in your main sewer line.

Immediate steps:

  • Stop using water in the affected fixture to avoid overflow.

  • Try a plunger designed for sinks or tubs, and apply consistent pressure to dislodge minor clogs.

  • Avoid using chemical drain cleaners, which can damage pipes over time, especially in older systems.

  • Remove visible debris like hair or soap scum from the surface area.

If the backup is severe or recurring, a plumber may need to inspect the drainage system and, in some cases, perform hydro jetting or camera inspection to find deeper blockages.

5. Leaking Faucet or Fixture

The situation: A faucet, hose bib, or showerhead won’t stop dripping, or worse, it’s spraying water erratically when turned on. While not as dramatic as a burst pipe, it can still waste water and cause localized damage.

Immediate steps:

  • Shut off the water supply to the specific fixture, typically found beneath the sink or behind the wall.

  • Check for obvious wear or loose fittings that may be hand-tightened as a temporary fix.

  • Place a towel or small bucket under the leak to prevent water from damaging cabinetry or flooring.

Persistent leaks often indicate worn washers, corroded fittings, or outdated components. If left unaddressed, they can increase your water bill and lead to mold or rot in surrounding materials.

Staying Prepared for the Unexpected

The best way to handle a plumbing emergency is to be prepared before one happens. Here are a few things every homeowner should do:

  • Know the location of your main water shut-off valve

  • Keep a basic toolkit (wrench, plunger, flashlight) nearby

  • Store contact info for an emergency plumber in an accessible place

  • Conduct routine checks of your water heater and exposed pipes

  • Schedule preventative inspections, especially before winter or storm seasons

Benjamin Franklin Plumbing reminds homeowners that while temporary fixes can limit damage, long-term solutions always require professional attention. Being prepared helps reduce panic and ensures that emergency plumbers can get straight to work when they arrive.
