What to Do When a Pipe Bursts: 7 Steps for NJ Homeowners

A burst pipe does not wait for a convenient time. Water keeps coming until someone closes a valve, and every minute it runs is more drywall, flooring and belongings ruined. Here is exactly what to do, in order, if a pipe lets go in your North Jersey home.

Step 1: Shut off the main water valve

Everything else can wait. Find the main shutoff and close it. In most North Jersey homes the main valve is in the basement on the front wall of the house, the side facing the street, right where the water line comes through the foundation. The water meter is usually right there too. Look for a valve just before or just after the meter.

Two kinds of valve are common. A round wheel handle is a gate valve: turn it clockwise until it stops. A lever handle is a ball valve: turn the lever a quarter turn so it sits across the pipe instead of in line with it. Homes on a slab, and some split-levels, may have the valve in a utility closet, the garage or a crawlspace near the water heater.

If the valve is stuck or broken, do not force it with a wrench. A gate valve stem can snap. Skip to Step 6 and tell us when you call. We can shut the water at the curb.

Step 2: Kill power to wet areas

If water is near outlets, extension cords, appliances, or the electrical panel in a finished basement, turn off power to that part of the house at the breaker panel. If the panel itself is in standing water, do not touch it. Call the utility or an electrician and stay out of the water.

Water and electricity together are the one part of a burst pipe that can hurt you, not just your house. Take this seriously.

Step 3: Open faucets to drain the lines

With the main closed, open the lowest faucet in the house, a laundry sink or basement spigot, and a faucet on the top floor. This drains the pipes and relieves pressure so water stops dribbling out of the break. Flush the toilets once. If the burst is on the hot side, this also stops the water heater from feeding it.

Step 4: Contain and remove the water

Move rugs, boxes and furniture out of the wet area. Mop, squeegee or wet-vac standing water. Set up fans. Open cabinet doors and closets so air moves. In a finished basement, pull back carpet so the pad can dry or be removed. Mold can start in damp material within days, so speed matters more than perfection.

• A bucket or tarp under an active drip from a ceiling
• Towels rolled along doorways to keep water out of the next room
• A wet-vac, if you have one, for standing water on hard floors
• Fans and a dehumidifier running as soon as the water is off
• Furniture lifted onto blocks or foil so the legs do not wick water

Step 5: Document everything for insurance

Before you throw anything out, take photos and video of the burst pipe, the water, and every damaged item and surface. Note the time you found it. Keep receipts for the wet-vac, fans, or any emergency cleanup. Call your insurer once the water is off and the plumber is on the way. Sudden pipe bursts are commonly covered; long-term slow leaks often are not, and the adjuster will ask what happened and when.

Ask the plumber to keep the failed section of pipe. Insurers sometimes want to see it.

Step 6: Call a licensed plumber

Call Master's Plumbing at 862-666-2155. Tell us where the break is, what the pipe is made of if you know (copper, PEX, galvanized steel), and whether the main is off. Active leaks go to the front of the line.

On the visit we cut out the failed section, replace it in copper or PEX, and pressure test the repair. We also look at why it failed. A pinhole in old copper or a split in a galvanized line often means the rest of the run is close behind, and it is better to know that now than at 2 a.m. in February.

Step 7: Know what NOT to do

• Do not turn the water back on to see how bad it is. It is bad. Leave it off.
• Do not wrap the pipe in tape or a rag and call it fixed. A compression clamp buys hours, not months.
• Do not leave the water heater running with the main off for long. If the tank drains down, the elements or the tank can be damaged. Set a gas heater to Pilot or turn off the breaker on an electric one if the water will be off for a while.
• Do not use a space heater, heat gun or open flame to dry a wet wall or thaw a pipe inside a wall.
• Do not walk through standing water in a basement where the panel or outlets may be live.

Frozen-pipe bursts in winter

In North Jersey, winter is burst-pipe season, and the usual cause is ice. Water expands as it freezes, the pipe splits, and nothing happens until the ice melts and pressure returns. That is why bursts often show up during a thaw, or when the heat comes back on after a furnace or boiler failure.

The pipes that freeze are the ones on exterior walls, in unheated crawlspaces and garages, in a kitchen sink cabinet on an outside wall, and hose bibs that were never shut off in the fall. If you find a frozen pipe that has not burst yet, close the main, open a faucet on that line, and warm the pipe gently with a hair dryer or warm towels, starting at the faucet end. Never use a torch.

If you had one freeze, you will have another. Ask us about insulating, rerouting or replacing the vulnerable run before next winter.
