01 / Right now
Stop the water, get people clear of gas or sewage, then take photos. A flashlight and maybe a meter key cover it.
Which valve do I close?Stop the water. Close the valve under the sink or behind the toilet. If the water comes from a wall, ceiling or the floor, close the main shutoff where the supply line enters the house, often beside the front hose bib.
Smell gas? Leave the house now and call 911 or SoCalGas from outside. Don't touch switches and don't try to relight a pilot.
If the water heater itself is leaking, set a gas unit to pilot or switch off the breaker for an electric one.
If sewage is backing up, stop using water and keep kids and pets away. Clean it up with gloves and disinfectant, or hire a cleaner.
Move what you can, mop up, and photograph the leak and the damage for your insurer.
Note what you saw and when, then call a CSLB-licensed plumber and ask for a diagnosis before a price.
02 / Shutoffs
Walk the house with this list once, on a dry afternoon, and turn each valve to make sure it moves. It takes about twenty minutes and no tools.
| Fixture | Where the valve is | How to close it | When it's urgent |
|---|---|---|---|
| Whole house | Main shutoff where the supply line enters the house, often beside the front hose bib or in the garage. A second valve sits in the meter box at the curb. | Ball valve: turn the handle across the pipe. Gate valve: clockwise until snug. | Any leak in a wall, ceiling or slab |
| Toilet | Angle stop low on the wall or floor behind the bowl. | Clockwise until it stops. If it won't move, use the main. | Overflow or water at the base |
| Kitchen sink | Two angle stops inside the cabinet. The dishwasher usually tees off the hot side. | Clockwise. An old multi-turn stop may drip at the stem once you move it. | Wet cabinet |
| Bathroom sink | Two angle stops under the vanity. | Clockwise until snug. | Drip under the vanity |
| Tub and shower | Usually no local stop. Some sit behind an access panel on the other side of the wall. | Use the main. | Water inside the wall |
| Water heater | Cold inlet valve on top of the tank. Gas units also have a gas valve on the supply pipe. | Close the cold inlet. Set gas to pilot, or flip the breaker on an electric unit. | Leaking tank or a gas smell |
| Washing machine | Hot and cold valves on the wall box behind the washer. | Clockwise, or flip the single lever. | Burst hose |
| Garden and irrigation | The hose bib handle. Irrigation often has its own valve near the backflow device. | Clockwise at the bib or the irrigation valve. | Rarely urgent |
If a valve sticks or starts leaking when you turn it, stop forcing it and close the main. A gas smell is different: leave the house and call 911 or SoCalGas from outside.
03 / La Palma
Builders put up most of La Palma in the 1960s and 70s, quickly and to a pattern. Houses on one block often share the same concrete slab, the same copper or galvanized supply lines and the same cast-iron or clay lateral out to the street. If your neighbor's pipe gave out last month, yours went in the same year.
We handle the everyday side of the trade: angle stops that weep, supply lines that split, toilets that run, drains that slow, water heaters that rumble and quit. We find the cause before we price the fix. A wet sink cabinet alone can trace back to three different parts.
Below you'll find the warning signs, the valve that stops each fixture, how we work through a repair, and the questions to ask any plumber, us included.
04 / Warning signs
In a system this age, a small symptom usually points at a bigger one. Take a closer look if you notice any of these.

05 / Our process
We follow the same order on each job: find the cause, explain it, put the scope and price in writing, then repair and test with you watching.
We ask what you saw, read the meter for a hidden leak and look at the fixture, valve or line you pointed to. A leak we can't see gets a pressure test or electronic leak detection.
A wet cabinet can mean a loose drain nut, a failed angle stop or a corroded supply line. A slow drain can mean hair in a trap or roots in the lateral. The cause sets the repair.
You get the problem, the proposed repair, any repair-or-replace alternative and the price on paper before we pick up a wrench.
We shut the water off, cover floors and cabinets, and replace the failed part with code-compliant materials. A water heater swap or a repipe also needs a city permit.
We restore water, check every joint under pressure and run the drains. On a water heater we also check the seismic straps, venting and relief valve line.
Your itemized invoice lists the parts, the work and any permit number, so the next person who opens that wall knows what changed.
06 / Typical calls
In older homes this is often a corroded angle stop or a braided supply line that has reached the end of its life, or a slip-joint drain nut that has loosened. Replacing the stops and supply lines together is common, since they tend to age at the same rate.
A warm floor over a slab can mean a hot water line leaking under the concrete. A plumber confirms it with pressure testing and leak detection, then talks through a spot repair through the slab versus rerouting the line overhead or through walls.
A leak from the tank itself usually means the heater needs replacing; a leak from a fitting or the relief valve may be repairable. California requires water heaters to be seismically strapped, and a replacement normally needs a permit.
When several fixtures back up together, the problem is usually in the main line or the sewer lateral, not a single trap. Tree roots in older clay or cast-iron laterals are a frequent cause, and a camera inspection shows what is actually there.

La Palma's streets share a building era and a water supply.
07 / Under the slab
La Palma is under two square miles and filled in fast, so the same failures show up street after street. Slab construction keeps supply lines under concrete. Galvanized steel rusts from the inside until a shower barely runs. Original cast-iron and clay laterals crack, settle and let roots in.
Our water is a blend of local groundwater and imported water, and it runs hard. Scale builds up in tank heaters, faucet cartridges, aerators and shower valves, so flushing the heater and soaking the aerators pay off here more than in most towns.

08 / Calling us
Keep the first call short. We'll ask where the problem is, what you've already shut off, how long it's been going on and whether the house sits on a slab. If you know the water heater's age or the pipe type under a sink, tell us.
Before anyone comes out, ask us, or any plumber, for a CSLB license number and how the visit and the repair are priced. You should see the diagnosis and the price in writing before work starts. While this site is in preview, the number shown is a placeholder, so don't count on it in an emergency.
Get the contractor's CSLB license number and look it up at cslb.ca.gov. Ask whether employees or subcontractors will be in your home, and get the price in writing before work starts. Confirm your address is inside the company's service area.
La Palma Plumber is the business name for this site. Licensing and service details will be published here once confirmed.
09 / Questions
In many tract homes it is a valve on the supply line where it rises out of the ground and enters the house, often near the front hose bib or the garage. There is also a valve at the meter by the street, which may need a meter key. Find yours before an emergency and check that it turns.
A leak from a fitting, the drain valve or the temperature and pressure relief valve may be repairable. A leak from the tank body usually means replacement. Age, hot water performance and whether the heater is properly strapped and vented all factor in.
Simple repairs such as replacing a faucet cartridge usually do not. Work like replacing a water heater, repiping or sewer line replacement generally does. Check with the City of La Palma for the current rules before work starts.
Common causes in older homes are scale-clogged aerators and cartridges, a failing pressure regulator, partly closed valves or galvanized pipe that has narrowed from internal corrosion. A plumber can test pressure at a hose bib and narrow it down.
Signs include a moving water meter with everything off, warm spots on the floor, the sound of running water when nothing is on and unexplained cracks or dampness. Leak detection by a plumber confirms where it is before any concrete is opened.
When multiple fixtures back up together the blockage is usually in the main drain or the sewer lateral. Roots, grease buildup and sagging or cracked pipe are common causes. A sewer camera inspection shows the cause and location.
Ask for the contractor's CSLB license number and look it up at cslb.ca.gov. The lookup shows whether the license is active, its classification and whether bonding and workers' compensation are on file.

Before anything else
Close the fixture valve or the main. If you smell gas, get out and call 911 or SoCalGas from outside. Keep everyone clear of sewage. Then pick a plumber whose CSLB license you've looked up yourself.
