Calling a plumber is not step one when a pipe splits. Step one is the main shutoff, step two is draining the lines, and step three is cutting power to the heater. Only then does it make sense to line up someone who can open the wall and make a lasting repair. Below you get that order, a price guide, and the rental and insurance wrinkles. Our broader write-up on leak and burst-pipe work sits one level up. Everything else we line up is on the Harbor Lights home page.
Water is pouring out right now, so what comes first?
Locate the main valve and crank it shut, clockwise. In most Long Beach houses it is near the meter box out front or on the outside wall beside the water heater; condos sometimes have a unit shutoff. Then run the tap that sits lowest in the building, and switch the water heater off at its breaker or move the gas dial to pilot.
Next, protect what you can. Lift valuables off the floor, take photos before any mopping, and keep clear of puddles that reach outlets or appliances. If water is dripping out of a ceiling fixture, that room's circuit should be shut off, but only from a spot where you are standing dry.
Our service takes requests weekdays from 9 in the morning until 5 in the afternoon. After hours, the shutoff holds things until then. If the failure sits upstream of your meter, customers of Long Beach Utilities can ring the city's water and sewer emergency line, (562) 570-2390. Homes in San Pedro and Wilmington get water from LADWP, which is the agency to reach there.
How does a pipe actually fail, and how can I tell?
Pressure, corrosion or metal fatigue opens a split, and water leaves at whatever force the system carries, commonly in the 50 to 80 psi range. Expect a bang or hiss, a spreading stain, a meter dial turning with every faucet closed, and weaker flow elsewhere in the house.
Not every burst is loud. Inside a wall it can sound like a thin trickle, announce itself with a floor that feels warm, a baseboard that puffs up, or nothing until the bill jumps. The quiet signs are collected in a separate piece on recognizing a burst line, while the underground burst guide deals with breaks in the yard.
Gas near the wet area adds a separate worry. Smell it and you walk out, then phone from the sidewalk. Long Beach and Signal Hill homes are supplied by the city's Long Beach Energy Resources, emergency line (562) 570-2140, whereas Lakewood, Seal Beach and San Pedro are on SoCalGas, 1-800-427-2200. Add a 911 call for a strong odor or anyone feeling unwell.
Do pipes burst from cold here, and at what temperature?
Seldom. Water freezes at 32 degrees, yet pipes inside heated walls rarely get there on the coast. The Insurance Institute for Business and Home Safety recommends setting the thermostat no lower than 55 degrees when frost is a concern. For a Long Beach house, age, rust and high street pressure explain more splits than ice does.
Bare lines in a garage, along an exterior wall or in a vented crawl space are the exception on a rare clear, cold night. Wrap them, and let a tap drip when a freeze is forecast. Causes are ranked in why pipes split; a prevention checklist follows from it.
Local housing matters more than weather. Belmont Shore and Bixby Knolls bungalows put up between the Roaring Twenties and Eisenhower can still carry galvanized steel water lines. Those corrode from within, and coastal salt air hurries the process, so a failure can arrive without a warning drip.
Will tape or a clamp hold until the plumber arrives?
A wrap, putty or rubber clamp is a stopgap and nothing more. On a dry, straight, reachable section, it may slow a drip for some hours. Lines run under constant pressure and expand and contract, so patches creep loose. Behind drywall, on a bend or on threaded steel, forget it and wait for a proper replacement.
Where a clamp does earn its place is a straight run under a sink: dry the pipe, wrap it tightly, and keep the main off if the household can manage without water. A spray sealant will not survive a night at full pressure. For a comparison of what each product can and cannot do, see the pipe leak sealant guide.
What will the repair run me?
Thumbtack's April 2026 national figures give $234 to $771 for a typical burst pipe repair, $98 at the cheapest and $1,905 at the dearest. Treat those figures as a ballpark. Pipe material, ease of reach and how much wall has to come off all push the total around, and a night or weekend call costs extra. You get the real price on paper once somebody has looked at the damage.
Cleanup frequently outweighs the repair itself. Drying equipment, drywall, flooring and paint can pass the plumbing bill. Per the EPA, absorbent materials like carpet or ceiling tile can end up in the dumpster, so quick drying saves money. For the cheap end, Thumbtack cites a pinhole in half-inch copper at roughly $150 on a job in Poway, California.
A split beneath a slab belongs in another category, since the crew must cut concrete or reroute the line. Those numbers live on our slab leak cost page. Finding an unknown leak is billed separately, as the note on leak detection cost explains.
I rent an apartment. Who is on the hook when the pipe breaks?
Usually the landlord. Civil Code section 1941.1 treats a unit whose plumbing does not work as uninhabitable, so notify the owner or property manager in writing at once and keep the message thread. Close the valve serving your unit where you can get to it, and photograph whatever of yours got wet.
Those belongings fall under renter's insurance if you carry it, not the landlord's policy. Pay attention to mold, since drywall that stays wet for days becomes a health issue of its own. If the landlord drags, a local tenant resource or the city housing office can outline options. Upstairs tenants should also warn the neighbors below, as water travels.
If I own the home, will my insurer pay for a burst pipe?
Water damage that follows an abrupt, accidental split is the part insurers most often pay. The broken pipe itself may be excluded, and slow seepage nearly always is. Policies vary, so check the declarations page. Some low-cost California plans leave water damage out altogether.
The state insurance department encourages owners to learn the coverage terms ahead of a loss rather than after one. Once a pipe goes: close the water, photograph everything, and notify the insurer promptly, sticking to what you saw and did. Skip guesses about cause. The plumber's invoice naming the failure usually counts for the most with an adjuster. Our piece on burst pipes and insurance describes how a claim tends to unfold.
Is the answer different for a bathroom, a crawl space or a sprinkler line?
The shutoff stays the first move, though the nearest valve differs. In a bathroom, try the fixture stop, the small oval handle near the floor, before the main. Basements are rare across Long Beach, so water usually collects in a crawl space or on a slab. A split sprinkler pipe is closed off at that zone's valve or the irrigation main.
In every room the plumber asks three things: where is the break, why did it happen, and is the neighboring pipe thin too? Work inside walls usually means access holes. Replacing more than a patch may require a city permit; Long Beach Building and Safety exempts stopping a leak that needs no new materials, so ask how your job fits. For the aftermath, the burst water pipe guide picks up where this leaves off.
Common questions
How fast does help arrive after a burst?
We make no promise on timing. Requests are read weekdays between 9 and 5. Use the quote page, say plainly that water is running, and shut the main while you wait, since that does the real work of limiting damage.
Is a burst pipe just another word for a slab leak?
No. A burst is an abrupt rupture that dumps a large volume fast. A slab leak sits in a supply line below the concrete floor and tends to be gradual. The clues differ (a warm spot on the tile, a meter that creeps) and so does the way it gets fixed.
The break is in the yard line, so who deals with it?
The utility looks after the line through the meter. Past the meter the line is yours, and Long Beach Utilities does not pay for private leak repairs. Close the meter valve if you own the key, and hire a plumber to trace and repair the run.
Can I handle the cleanup alone?
Pumping out standing water and opening windows is fine. Soaked drywall, insulation or carpet has to dry quickly, though. The EPA advises fixing the plumbing problem and drying everything fully, and puts mold patches larger than roughly ten square feet in the specialist category.
Does fixing a burst require a permit?
Long Beach says plumbing alterations and repairs generally need one, with an exemption for stopping a leak or minor repair using no new materials. Swapping out a longer stretch of pipe probably falls under the permit rule. The plumber should tell you which side you are on and pull the permit if needed.
