What to Do the Moment a Pipe Bursts
A half-inch supply line can release hundreds of gallons of water into your home in a single hour. What you do in the first ten minutes after a pipe bursts often determines whether the damage is limited to a quick repair or turns into a major restoration project. This guide walks through the five critical steps every homeowner should take: shutting off the water, cutting power safely, draining the system, documenting the damage, and getting professional help. It also covers how to prepare before a burst happens and what to do while waiting for the plumber to arrive.

1. Shut off the main water valve
The first and most important step is stopping the flow of water. The main shut-off valve is usually located where the water service line enters the house, often in the basement, crawl space, or utility room near the water meter. In some homes, it is in a mechanical closet or near the front foundation wall.
Turn the valve fully clockwise until it stops. If you have a lever-style ball valve, turn it perpendicular to the pipe. Gate valves may require several rotations. Do not force it. If the valve is stuck or corroded, leave it alone and call for emergency help — breaking the valve can make the situation worse.
Every adult in the household should know where the main shut-off is before an emergency happens. If you have never tested yours, do it now. A valve that has not moved in decades is likely to seize exactly when you need it most. Exercising it once a year keeps it operational.
2. Cut power to affected areas
Water and electricity are a dangerous combination. If water is anywhere near outlets, electrical panels, appliances, or light fixtures, shut off the circuits that serve those areas at the breaker panel. This reduces the risk of shock and prevents further damage to appliances.
Never stand in standing water to reach a breaker panel. If the panel itself is wet or you must walk through water to reach it, leave the house and call an electrician. Do not take risks. A professional can disconnect power safely.
If the burst pipe is in an unfinished basement with exposed wiring, be especially cautious. Even a small amount of water on a concrete floor can conduct electricity. When in doubt, evacuate the area and wait for professionals.
3. Drain the system and relieve pressure
Once the main water is off, open the lowest cold-water faucets in the house, usually in a basement sink or laundry tub. Then open the highest faucet, often an upstairs bathroom sink. This creates a path for remaining water to drain out of the pipes and relieves any pressure still trapped in the system.
Flush the toilets to empty the tanks and bowls. If the burst pipe is on a hot-water line, also open hot-water taps. Be careful — the water may still be hot. Draining the system reduces the amount of water that can leak from the break and helps the plumber start work faster.
If you can safely access the area around the burst pipe, place buckets or towels to catch any remaining drips. Move valuable items, electronics, and furniture away from the water. The less time water sits on floors and walls, the less damage it causes.
4. Document everything for insurance
Before you start cleaning up, take photos and videos of the burst pipe, the water damage, and any affected belongings. Capture wide shots of the room and close-ups of specific damage. This documentation is what your insurance company will ask for, and it takes only a few minutes.
Make a rough list of damaged items with their approximate age and value. Save receipts for any emergency supplies you buy, such as fans, dehumidifiers, wet-dry vacuum rentals, or temporary repairs. Many homeowners' insurance policies cover reasonable emergency mitigation costs.
Do not throw away damaged items until the insurance adjuster has seen them, unless they pose a health risk. Mold can begin growing within 24 to 48 hours, so document quickly and then start drying the area as soon as you have the photos you need.
5. Request plumbing help and start drying
Call us or submit an online service request 24/7 across Putnam County. While you wait for the plumber, start removing as much standing water as possible. Use a wet-dry vacuum, mops, or towels. Set up fans and a dehumidifier to move air and pull moisture out of walls, floors, and furniture.
Remove wet rugs, pillows, and other absorbent items from the area. Pull furniture away from walls so air can circulate behind it. If baseboards are wet, removing them can help drywall dry faster and reduce the chance of mold growth behind the wall.
When the plumber arrives, point out the burst area, the shut-off valve location, and any other concerns. A professional can repair or replace the damaged section, check for additional freeze risk, and advise you on whether the rest of the system needs inspection.
How to prevent the next burst
Most bursts happen because a pipe froze first. After the immediate repair, ask the plumber to identify other pipes at risk. Insulate exposed lines, seal air leaks, and consider heat cable for pipes that have frozen before.
If you plan to be away during cold weather, keep the thermostat at 55°F or higher, open cabinet doors under sinks, and let faucets drip during severe cold snaps. For extended travel, shut off the main water and drain the system entirely.
A little prevention goes a long way. The cost of insulating a few pipes and sealing a crawl space is a fraction of the cost of repairing water damage, replacing flooring, and remediating mold.
