How to Handle a Plumbing Emergency: 10 Tips for Homeowners

When a plumbing emergency hits, shutting off the water is the fastest way to stop damage. Learn how to find and turn off your main water supply before the problem gets worse.

A small step that can prevent bigger damage.

Turn Off the Water Heater

If a plumbing emergency involves hot water lines, flooding near the water heater, or a burst pipe, turning off the water heater helps protect the unit and reduces safety risks. Water heaters aren’t designed to run without water, and continuing to heat an empty or damaged system can cause serious internal damage.

Using the system can make the problem worse.

Stop Using Water Fixtures

Once a plumbing emergency starts, running faucets, flushing toilets, or using appliances can increase pressure in damaged pipes or push backups further into your home. Even if the issue seems isolated, it’s safest to stop using all plumbing fixtures until the water is shut off and the problem is properly diagnosed.

Water and electricity don’t mix.

Watch for Electrical Hazards

If water is spreading near outlets, extension cords, or electrical panels, your safety comes first. Standing water can carry electricity, and even shallow flooding can create a serious shock risk. Avoid walking through wet areas if you’re unsure what’s energized.

If it’s safe to do so, shutting off power at the main breaker can reduce the risk of injury and prevent electrical damage. Never touch electrical panels or switches while standing in water, and don’t attempt to move wet appliances.

Small actions now can prevent costly repairs later.

Limit the Water Damage

Use towels, buckets, or shallow pans to catch active drips and slow the spread of water. If possible, move furniture, rugs, and personal items out of the affected area to reduce damage.

Light mopping is fine for small amounts of water, but avoid using household vacuums unless they’re designed for wet use. If water is spreading quickly, focus on safety and shut off the main water supply first.

 

Yes. Opening cabinets under sinks and interior doors can help air circulate and reduce moisture buildup, especially if the leak has been stopped.

If water is soaking into walls, ceilings, or flooring, or spreading to multiple rooms, it’s time to call a professional. Hidden moisture can lead to mold and structural issues if not addressed properly.
