A burst pipe in West Hollywood, CA can put a kitchen floor underwater in minutes, and the first hour decides how far it spreads. A burst pipe is a water line or fitting that fails under pressure and releases water continuously until the supply is closed.
Callers describe it plainly: a pipe under the sink let go this afternoon and water is all over the floor, or it feels like the whole house is flooding. The steps below work for both situations.
The first-hour sequence
Stop the supply
Close the fixture valve under the sink or toilet. If you cannot find it, close the main water valve for the unit or building.
Make it safe
Avoid wet outlets and cords. Turn off power to wet areas only if the panel is dry and reachable.
Protect and photograph
Lift valuables and rugs, then take photos of the source and the water.
Call for help
Call a plumber for the repair and the 24/7 line for water removal.
Find and close the right valve
Most sinks and toilets have a small oval or round valve on the supply line. Turn it clockwise until it stops. If water keeps flowing, close the main valve for your home, which is often near the water heater, in a utility closet or at the building's entry point.
In an apartment building, the main for your unit may sit in a shared closet or the property manager may control it. Call them at once if you cannot reach it. Once the supply is off, opening the lowest faucet in the building can drain the lines, but only when it is safe to do so and no water is near electrical equipment.
Power and electrical safety
Water and electricity do not mix
If water has reached outlets, appliances or the panel, do not stand in it. Call 911 for any electrical or gas risk before you call anyone else.
Switch off power to the wet area only if the breaker panel is dry and you can reach it without crossing water. When unsure, leave the power alone and get out.
Pipe burst and water spreading?
The 24/7 emergency line is open. Describe the source and the wet rooms, and a crew can be sent when available.
Decide who to call and when
| Situation | First call | Why |
|---|---|---|
| Water still flowing and valve will not close | Utility or building manager, then plumber | Someone must close the supply |
| Supply closed, standing water on floor | Restoration line for extraction | Water must be removed and the area dried |
| Water near panel or outlets | 911, then restoration line | Electrical risk comes first |
| Small leak, no standing water | Plumber | Repair first, then check for hidden moisture |
A plumber repairs the pipe and a restoration crew removes the water. You usually need both.
What the removal and drying crew does
Pumps and extraction units pull standing water from the floor, then crews open any wall or cabinet that trapped moisture and set up drying equipment. Our emergency water removal page covers that first stage and our water mitigation page explains the drying that follows.
A burst supply line sends clean water at first, but it can pick up dirt and materials as it spreads. A crew checks the water category and decides which finishes can be saved and which should be removed.
Mistakes that make a burst pipe worse
- Waiting to see if the leak slows down before closing a valve.
- Running a household vacuum on standing water, which risks shock and damages the motor.
- Walking through water toward an outlet or panel.
- Leaving soaked rugs and cardboard in place while the floor stays wet.
- Painting or sealing a surface before it has been checked with a moisture meter.
Each of these either lets more water out or traps moisture where it can do more harm. When in doubt, close the supply, stay clear of electrical equipment and call for help instead of improvising.
Hidden moisture after the surface is dry
Water from a pipe inside a wall or under a cabinet travels along studs and behind baseboards. The floor can look dry while the wall bottom and the cabinet base stay wet. Crews open small inspection holes and use thermal cameras and moisture meters to follow the water.
If you notice a musty smell, warped baseboards or paint that bubbles in the days after, call back and ask for a recheck. These signs point to moisture still sitting in the building.
Prepare before a pipe fails
A few minutes of preparation pays off in an emergency. Find every shutoff valve in your unit and test that each one turns. Label the main and tell everyone in the household where it is.
- Locate the fixture valves under sinks and behind toilets.
- Find the unit main or the building main and note who controls it.
- Keep a flashlight and a list of the plumber and restoration numbers near the panel.
- Photograph your belongings room by room now, so a later claim has a starting point.
Who controls your shutoff and what needs a permit
The City of West Hollywood states that LADWP serves most areas of the city and Beverly Hills Water serves certain areas on the west side. The street-side meter shutoff belongs to whichever utility serves your building, so know which one it is and where your building's main valve sits before an emergency. In multi-unit buildings, ask your property manager now, not during a flood.
The city's Building and Safety FAQ says the repair of leaks in water piping, valves or fixtures does not need a permit, while replacing drain, soil, waste or vent piping does and requires an inspection. Ask the city's Building and Safety division if you are unsure how your repair is classified. If your property sits near the western edge, Beverly Hills has its own building permit center.

Common questions from West Hollywood readers
Should I turn off the water main for a burst pipe?
Yes if the fixture valve will not close or you cannot find it. Close the main for your unit, or ask the property manager to close the building main.
Do I need a restoration crew if I mop up myself?
If water reached walls, cabinets or subfloor, hidden moisture can remain. A crew uses moisture meters to check, and the EPA suggests drying within 24 to 48 hours to prevent mold.
Is the restoration line open at night?
Yes. The line is open 24/7, including nights, weekends and holidays, and a crew is sent when available.
Can I repair the pipe myself?
Minor fixture repairs sometimes are simple, but a failed supply line or a pipe inside a wall is best handled by a plumber. Ask the city's Building and Safety division about permits.
How do I know which utility serves my West Hollywood building?
Check your water bill or ask your property manager. The city says LADWP serves most areas and Beverly Hills Water serves certain areas on the west side.
