A heater that has quit or started leaking needs emergency water heater repair in Marina, CA, and our 24/7 line at (855) 575-2890 is open every hour. While you wait, close the cold water valve above the tank. Then switch off the breaker or turn the gas control to off, and keep people away from standing water near outlets.
We offer same-day appointments when available. A licensed and insured plumber finds the fault and gives you a clear price before work starts, so you can weigh repair against replacement with real numbers. If the unit is old, we will say so plainly.
No hot water or a leaking tank: what to do first
Water seeping from the base of the jacket usually means the steel tank has rusted through, and that cannot be patched. A drip at the pipes on top, or at the relief valve, is often a fixable part.
- Close the cold water shutoff valve on the pipe above the heater. Turn the handle clockwise until it stops.
- Electric unit: switch off its breaker. Gas unit: turn the gas control knob to off or pilot.
- Open one hot tap in the house so the system can vent while the tank cools.
- Move boxes and stored items away from the base, and put a bucket under any steady drip.
- Call (855) 575-2890 and tell us the fuel type, the tank size on the label, and where the water is coming from.
If you smell gas
Leave the house, do not touch switches or light anything, and call 911 from a safe distance. Then call your gas utility. In PG&E territory that number is 1-800-743-5000. Do not try to relight a pilot until the smell is gone and the source is found.
A drain pan under the tank buys only a few minutes. Shutting the cold valve stops the refill and limits the damage.
Common water heater faults and how they are fixed
Most heater calls come down to a short list of parts. The table shows how symptoms usually map to causes, so you know what to expect before a plumber arrives.
| Symptom | Likely cause | Usual repair |
|---|---|---|
| No hot water, gas unit | Pilot out, failed thermocouple, or gas control fault | Relight and test, replace thermocouple, or replace control |
| No hot water, electric unit | Tripped high-limit switch, failed element or thermostat | Reset, then replace the failed element or thermostat |
| Rumbling or popping from the tank | Sediment and scale baked onto the bottom | Flush the tank, or replace if scale is heavy |
| Water at the relief valve pipe | High pressure, thermal expansion, or worn valve | Test pressure, add expansion tank, replace valve |
| Pooling under the tank | Rusted tank body | Replacement, since the tank cannot be repaired |
Tell us any error code on the display when you call. It helps us plan the visit.
Gas heaters: pilot light and thermocouple problems
On a standing-pilot gas heater, a thermocouple is a safety sensor. It detects the pilot flame and lets gas flow to the burner. When it wears out, it shuts the gas off even if the pilot looks lit, which is why a pilot that drops out after a few minutes often points to this part.
A thermocouple swap is a short job, and published cost guides put it near $150 when a plumber does it. If the pilot still will not hold, the cause may be a bad gas control valve or a blocked vent, and that needs a professional.
- A rotten-egg smell means leave first and call 911, then the gas utility.
- Carbon monoxide alarms near gas appliances are worth testing. A CO alarm senses carbon monoxide, not natural gas.
Electric and hybrid heat pump heater repairs
Standard electric heaters use two heating elements and two thermostats. If you get lukewarm water, the lower element is often the one that failed. If you get none, the upper element, a thermostat, or the high-limit reset may be at fault.
Hybrid heat pump heaters add a compressor, a fan and a condensate drain on top of the tank. Typical problems include a clogged air filter, a blocked condensate line, or a fault code that sends the unit into backup electric mode.
Bring up the brand and model when you call. If you have a heat pump unit and are asking about a swap, ask the City of Marina Building Division at (831) 884-1241 how current rules apply to your situation. We do not guess at code on the phone.
Marina water, scale and the anode rod
Marina Coast Water District reports moderately hard to hard water. Its 2025 water quality report shows total hardness averaging about 10.5 grains per gallon, ranging from 4.9 to 19.3, and the district disinfects with chlorine. District guidance suggests flushing the water heater regularly, following the maker's instructions, to limit mineral buildup.
That matters at your tank. Hard water drops minerals onto the bottom and onto heating elements, which causes rumbling and early element failure.
The anode rod is a metal rod inside the tank that corrodes so the steel does not. Guides suggest checking it every few years. A replacement runs about $50 to $150 including labor in published guides, and it can add years to a sound tank. A tank that is already leaking cannot be saved this way.
Repair or replace? An honest look at the trade-offs
Tank heaters often last about 8 to 12 years, per national cost guides. A younger unit with a single failed part is usually worth repairing. An older tank with a leak, heavy rust or repeat failures is usually not. We will tell you which side your unit falls on and show you both prices.
| Job | Typical range |
|---|---|
| Water heater repair, overall | $222 to $990 |
| Gas heater repair | $150 to $500 |
| Electric heater repair | $20 to $300 |
| Pilot relight service call | $50 to $150 |
| Thermocouple replacement | about $150 |
| Anode rod replacement | $50 to $150 |
| Tank-style replacement, installed | $600 to $2,500 |
Ranges come from national contractor-marketplace guides, and local prices differ. Your price depends on the fuel, the failed part, access to the unit and the tank's age. If you lean toward a new unit, see our pages on water heater replacement and tankless water heaters.
Night and weekend water heater calls in Marina
Our line is open 24 hours a day, and we offer same-day appointments when available, including after hours. A tank that is leaking at 2 a.m. does not need to wait for office hours.
We serve Marina, Seaside, Castroville and nearby Monterey County. If a leak has soaked a wall or floor, tell us. Water that has spread beyond the tank is worth a separate look, and our leak detection service can trace hidden moisture.
Frequently asked questions
Yes. Our line at (855) 575-2890 is open 24 hours a day, seven days a week, and we offer same-day appointments when available. Close the cold water valve above the tank first, then call so we can plan the visit.
A failing thermocouple is a common cause, but a draft, a dirty pilot tube or a bad gas control can do the same. If you smell gas, leave and call 911 first. Otherwise, avoid repeated relights and call us.
No. A leak at a pipe fitting, the relief valve or a drain valve can often be repaired. Water that seeps from the bottom of the tank means the tank itself has corroded, and that needs a new unit.
National cost guides show repairs from about $222 to $990, with simple parts like a thermocouple near $150. Your price depends on the part and access. We give a clear price before work starts.
We do not state a Marina permit rule from the phone. Call the City of Marina Building Division at (831) 884-1241 and ask. A plain repair, such as a new thermocouple, is a different question from a replacement.
It can. Marina Coast Water District reported about 10.5 grains per gallon on average in 2025. Minerals settle in the tank, so flushing it regularly, as the district recommends, helps.
