What to Do in the Event of a Plumbing Leak

A plumbing leak can go from a minor nuisance to a full-blown disaster in the blink of an eye. Whether it’s a dripping tap, a burst pipe in the ceiling, or an overflowing toilet, knowing how to respond quickly and effectively can help you minimize water damage, protect your property, and prevent long-term hazards like mold and mildew. 

Have no fear! Priority Plumbing is here to walk you through the right steps to take during a plumbing emergency — so you can protect your home and belongings.

Step 1: Shut Off the Water Supply Immediately

When water starts leaking, time is of the essence. The very first thing you should do is turn off the water supply to prevent additional flooding. Look for the nearest shut-off valve, which is usually located under the sink, behind the toilet, or next to your washing machine. 

If you’re unsure where the leak originates or if it’s a major burst, shut off the main valve to your entire home. Knowing where this valve is located ahead of time is crucial in any plumbing emergency.

Turning off the water quickly can help reduce the risk of:

  • Pressure buildup
  • Ceiling collapse
  • Floor warping
  • Water damage to electronics, building materials, and furniture

Once the flow stops, it’s easier to assess the situation calmly.

Step 2: Address Immediate Hazards

Once the water is off, it’s time to think about safety. Electricity and water are a dangerous mix, so if the leak is near outlets, your furnace, or electronics, cut the power supply to that area. Use a vacuum or towel to absorb excess water. Mop up visible puddles and place buckets or basins under ceiling leaks. If your basement has standing water, a sump pump or wet/dry vacuum cleaner can help remove it. Open windows or turn on a dehumidifier to lower humidity and reduce the risk of mildew and bacteria growth.

Place towels, plastic sheeting, or waterproofing materials under vulnerable furniture and use fans to help circulate air and prevent moisture buildup. Be careful with rugs and carpets — they can trap water and become breeding grounds for mold if not dried properly.

Step 3: Call a Licensed Plumber for Leak Detection and Repairs

Now that you’ve stabilized the immediate danger, it’s time to call in the professionals.

Step 4: Prevent Further Damage and Document Everything for Insurance

After contacting a plumber, take steps to document the damage. Take photos of the leak, affected appliances like your dishwasher or boiler, and any damage to drywall, flooring, or furniture. This documentation is vital when filing a claim with your home insurance or warranty provider. Don’t discard any damaged items until your insurance company gives you the go-ahead.

Check your home insurance policy for details on plumbing emergencies and water damage coverage. Some plans cover leaking pipes and mold remediation, while others may require additional flood or water backup insurance. Keep all receipts from repairs, disinfectant treatments, and moisture cleanup tools — these might be reimbursable under your policy.

Step 5: Take Preventive Measures for Future Plumbing Emergencies

Once the immediate issue is under control, use this experience as a lesson in prevention. Schedule regular plumbing inspections and maintenance to identify corrosion, wear, or pressure issues before they become leaks. Check that your sump pump is working correctly, especially during colder months when freezing temperatures can cause pipe damage. 

Consider upgrading older hoses on your washing machine and look into installing a leak detection system. Not only can this save water and prevent damage, but it can also improve indoor air quality by reducing humidity and the potential for mold growth.

Don’t overlook the importance of clean drains and proper sewage drainage. Avoid pouring grease or debris down the kitchen sink and regularly use a plunger or safe drain cleaner to keep the pipes flowing freely.

Don’t Let a Leak Turn Into a Disaster

A plumbing leak can be overwhelming — but with the right steps, you can protect your home, your health, and your wallet. Shutting off the water, calling a trusted plumber, documenting for insurance, and taking preventive steps all play a vital role in managing a plumbing emergency.
