When a pipe splits or a sewer line backs up in Castroville, you need an emergency plumber in Castroville, CA 95012 who answers the phone. Our line, (855) 575-2890, is open 24 hours a day, 7 days a week from our dispatch base in Marina. Close the main valve, stop running water into drains, and keep everyone away from wet outlets until we arrive.
Castroville has its own water district, its own seasons of trouble and a mix of housing ages. This page covers how those shape the calls we take. We offer same-day appointments when available, and you get a clear price before work starts.
A town, not a city: what that means for your plumbing
Castroville is a census-designated place in Monterey County, not an incorporated city. The 2020 Census counted 7,515 people there. Your ZIP is 95012, and you have no city hall, so the Castroville Community Services District handles water, sewer and other local services.
The practical result is that a street-side problem goes to the district, while a problem inside your property line is yours. District offices are at 11499 Geil Street, phone (831) 633-2560. We repair the pipes you own, and we tell you plainly when the fault is on the district's side so you do not pay for the wrong repair.
Census figures for 2020 to 2024 show 45.5 percent of Castroville homes are owner-occupied, so many households rent. If you rent, shut off the water, tell your landlord, then call us with their contact. Our drain cleaning work serves owners and managers alike.
Finding you: Merritt Street, Speegle Street and Highway 183
Dispatch works best with a cross street. In Castroville, useful ones include Merritt Street where it meets State Route 183, Washington Street, and Castroville Boulevard near the Highway 156 interchange. The county library branch sits at 11160 Speegle Street. Highways 1, 156 and 183 all meet near town, and Caltrans has road work planned between Marina and Castroville from October 2026 to April 2027.
That road work is a reason to give us a clear address and a landmark. We do not promise arrival times, because traffic and closures change the trip. We will tell you what to shut off while we are on the way.
Rain season, low ground and sewer backups
Castroville sits near Elkhorn Slough and Moro Cojo Slough. News reports from March 12 and 13, 2023 said the Sheriff's Office issued evacuation warnings for low-lying parts of Castroville after heavy rain. We cite this only as reported, but it shows why a wet winter deserves a plan.
During long storms, a sewer lateral can slow down, and a yard drain can overflow near the foundation. Know where your cleanout is, keep it clear, and call early rather than after the water reaches the floor.
| Season | What to watch | What to do |
|---|---|---|
| Wet winter months | Slow drains, soggy yards near cleanouts, wet crawl spaces | Locate the cleanout and the main valve, and call early for a camera check |
| Spring | Irrigation lines coming back on, hose bib leaks | Run each outdoor tap and look for drips and wet soil |
| Summer and harvest | Heavy water use, busy kitchens, grease in food-business drains | Schedule drain cleaning before the busy weeks |
| Fall | Water heaters working harder as nights cool | Flush the tank and check the relief valve line |
If a backup does reach the floor, the district operates the sewer collection system and sends flow to a Monterey One Water pump station on Watsonville Road. Our sewer line cleaning and sewer line repair work covers the pipe from your house to the property line.
Water from the district: hardness and what it does to fixtures
Castroville Community Services District serves more than 7,000 customers through 2,145 water connections. According to its 2025 report, the water comes from wells in the 400-foot and 900-foot aquifers. Average hardness was 145 ppm, with a range of 25 to 243 ppm. As a rough conversion, 145 mg/L is about 8.5 grains per gallon, which counts as moderately hard.
The same report lists total dissolved solids at 527 ppm on average and nitrate at 0.6 ppm. For you, hardness is the number that matters most. It leaves white scale on shower heads and faucet screens, and it builds up inside a water heater tank. Flushing a heater once a year slows that buildup.
If scale keeps clogging aerators or fixtures, ask us about a water softener and filtration setup. Samples ranged widely, so test your own tap before you buy any equipment.
Pipes, leaks and the water line to the street
Castroville's homes come from many eras, and we do not quote a median year because the figures we found came from secondary sources. One house may have copper and the next galvanized steel, so we check your pipes rather than assume.
A sudden jump in your bill, a damp patch in the yard or a meter that keeps moving with every tap off points to a hidden leak. Our leak detection visit traces it with sound and moisture tools before we dig. When the leak is in the line from the meter to the house, a water service line repair is the fix.
Gas smell? Do not wait for a plumber
Leave the building, call 911 from a safe distance, and then call your gas utility. We do not promise a response time for gas leaks, and a plumber is never the first call for one.
Farm-town businesses and the Artichoke Center nickname
Castroville is nicknamed the Artichoke Center of the World, and the town still depends on food, farming and the shops that serve them. Restaurants, packing sheds and small stores all share one concern, which is grease and solids in the drain line.
Food-service kitchens in the Marina Coast Water District area follow a grease program under that district's code. Castroville's own district rules may differ, so ask the district for yours. Our commercial plumbing crews can plan routine cleanings around your service hours.
Next door: Prunedale, Moss Landing and Marina
Prunedale is a separate community nearby. It has no ZIP of its own, and its mail uses 93907, which the Postal Service lists under Salinas. That is not Castroville's ZIP, so do not give it for a Castroville address. Moss Landing, ZIP 95039, sits on Monterey Bay up the coast.
We name these places so you know we recognize them, not to promise coverage at every address. Call and give us the street. Our base is in Marina, and the stretch between is mostly farmland. For the south side, see our Seaside page, or browse every service area.
Frequently asked questions

Castroville has one ZIP, 95012. Nearby places have their own mail codes, and Prunedale uses 93907, which is not a Castroville ZIP. For any address near the town edges, call with the street and we confirm coverage.
No. It is a census-designated place in unincorporated Monterey County. The Castroville Community Services District provides water and sewer, and county rules apply to building and permit questions. Ask the county office whether a repair like a water heater swap needs a permit, since we could not confirm that rule.
The district's 2025 report gives an average of 145 ppm, with samples from 25 to 243 ppm. That is about 8.5 grains per gallon on average. Expect scale on fixtures and inside water heaters over time.
Generally the property owner handles pipes on the house side of the meter, while the district handles its own mains. Because rules differ by district, call the district at (831) 633-2560 if you are unsure. We can find the leak and explain who owns the repair.
We handle plumbing, such as backed-up laterals, failed cleanouts and indoor water damage from broken pipes. For standing water from rain, call the county. If water is rising toward the house, shut off power to wet areas and call 911 if anyone is in danger.
Call us with the street address. We will tell you whether we can dispatch there. We do not publish drive times, since highway traffic and road work change the trip.
