Water on the floor, a gurgling drain or no hot water: start here
Match what you see to the most likely cause, then take the first safe step. The last column tells you whether to phone the 24/7 line now.
| Symptom | Likely cause | First move, and call now? |
|---|---|---|
| Wet floor under the sink | Failed supply line or drain fitting | Close the stop valve. Call now only if it will not close |
| Wet ceiling or stain spreading | Leak in an upstairs supply or drain | Shut the main valve and call now |
| Gurgling toilet, slow tub, sewage smell | Partial blockage in the main drain | Stop using water and call now if it backs up |
| Cold water only from the shower | Tripped element, pilot out or failed heater | Check the breaker or pilot, call if you see a leak |
| Water heater puddle | Tank corrosion or loose fitting | Shut the cold supply to the tank and call now |
The hot water heater problem Cudahy callers describe most
A heater that runs lukewarm or spits rusty water is often near the end, especially in a rental where nobody has flushed it. A leak from the tank body means water heater repair cannot fix the corrosion inside, and a replacement is the straight answer. A leaking fitting, valve or element is a repair.
Ask your landlord who owns the heater before you buy one. Tell the plumber what fuel it uses, since gas and electric tanks need different parts. For gas, leave the area and call SoCalGas right away if you smell it.
Why 19,400 people per square mile is hard on old pipes
Cudahy packs 5,854 housing units into 1.18 square miles, and 82 percent are rented. More people per fixture means more flushes, more dishes and more grease, which wears drains and supply valves faster. Repeat clogs are usually a pipe condition, not just a bad habit.
If a drain has been cleared and clogs again within weeks, ask for a camera inspection before another cleaning. It shows whether roots, a crack or a sagging section sits behind it, and it gives a tenant or landlord evidence to act on.
Do this at home while the line rings and the plumber heads out
You may be in a rental, so these steps are about limiting damage and gathering what the plumber needs.
- Shut off the main valveTurn the valve at the house or meter clockwise. In a rental, ask the landlord where it is if you cannot find it.
- Kill power to wet areasSwitch off the breaker feeding any wet room, and do not step in standing water near plugged-in devices.
- Clear the areaLift rugs, move boxes and keep children and pets out of the wet room. Photograph the damage for your landlord.
- Call the 24/7 lineTell us the symptom, what you shut off and who owns the property. Same-day appointments are available when a visit can safely wait.
If you smell gas, leave the building and call SoCalGas or 911 before calling us. Repairs in Cudahy follow the California Plumbing Code (UPC based), and whether a job needs a permit is a question for the city.
Big old lots, long pipe runs and a high bill with a dry house
In 1908, Michael Cudahy bought 2,777 acres of ranch land and resold it as large Cudahy lots for gardens, orchards and animals. Some properties still reflect that, with a back unit or garage set far from the street, so the water line and sewer lateral can run a long way underground.
A long buried line can leak quietly for weeks. If your bill jumps and nothing is wet, turn every tap off and watch the meter. When it still moves, leak detection with ground microphones can locate the line break before anyone digs, and it keeps the repair limited to that stretch.
Which water company bills your Cudahy address
The City of Cudahy lists three providers: Golden State Water Company, Tract 349 Mutual Water Company on Santa Ana Street, and Tract 180 Water Company on Florence Avenue in Bell. Which one serves you depends on the address, so check your bill.
If Golden State Water bills you, its 2025 report for the Bell and Bell Gardens system gives average hardness near 210 mg/L, about 12 grains per gallon. Numbers vary by block, so test your tap. A heater on hard water benefits from yearly flushing, and tankless units need descaling.
Elizabeth Street, Santa Ana Street and where Cudahy ends
Cudahy is small, so landmarks help. The post office is on Elizabeth Street and the library on Santa Ana Street. The city borders Bell to the north, Bell Gardens to the east, South Gate to the south and southwest, and Huntington Park to the west.
That is why a 90201 address can belong to Cudahy, Bell or Bell Gardens. We serve all of 90201 and 90255, the Huntington Park border ZIP, and we serve neighbors in South Gate and Bell too. Read the dispatcher your cross street so the right truck heads out.

Questions homeowners ask
Yes. ZIP 90201 covers Cudahy and is shared with Bell and Bell Gardens, so it takes in the blocks around Elizabeth Street and Santa Ana Street. ZIP 90255 is the Huntington Park border on Cudahy's west side. If your address is near a city line, give us the cross street when you call.
Yes. The emergency line is open 24/7, including nights, weekends and holidays, and dispatch covers Cudahy around the clock. We schedule same-day appointments when available and do not promise arrival windows. Shut off the main valve while you wait and tell the dispatcher what you did.
A buried line can leak without any wet spot, especially on a long run from the street to a back unit. Turn off every tap and watch the meter. If it still moves, call us. We use listening equipment to find the leak, then limit the repair to that section.
It can mean a partial blockage in the main line or a vent problem. If several fixtures gurgle or a floor drain bubbles, stop using water and call. A camera inspection shows whether roots, grease or a broken section is the cause, which helps the landlord choose between cleaning and repair.
That depends on your lease and the landlord. Tell the landlord immediately, and ask us for a written note describing the failure. In an emergency, shut the cold supply and power so the leak stops. We can then quote a replacement for the landlord.
We advise against it. Chemical cleaners can sit in a stopped line, burn skin and damage old pipe, and they make a later cable or jet job riskier for the plumber. Try a plunger, then call us for drain cleaning if the clog stays.
