Do You Know What Kind of Pipes Are in Your Walls? Huntington Park Is Trying to Find Out.

Do you know what kind of pipes are running behind your drywall, under your slab, or connecting your house to the water main in the street? If you're like most homeowners in Huntington Park, the honest answer is probably no. And you're not alone. The city itself didn't have a complete picture either, which is exactly why they started a new inventory program this year.

The City Wants to Know What's Underground

Huntington Park recently launched a Lead Service Line Inventory (LSLI) program in partnership with a company called TruePani Inc. The goal is straightforward: figure out what every single water service connection in the city is made of. That means cataloging roughly 6,600 connections across the entire system.

Why now? The EPA updated its Lead and Copper Rule back in 2021, and the revised requirements put pressure on cities across the country to identify and eventually replace any lead service lines. Huntington Park is responding to those federal rules, but the local angle matters just as much. This is a city where a lot of the housing stock went up before 1986. That year is the cutoff because Congress banned lead solder in plumbing that year. So if your home on Bickett Street or over near San Antonio Drive was built in the 1950s or 1960s, there's a real chance the original plumber used lead-based solder on your copper joints.

To be clear, having lead solder doesn't automatically mean your water is contaminated. The risk depends on water chemistry, how long the water sits in your pipes, and whether the solder has corroded over time. But the whole point of this inventory is to stop guessing and start knowing.

What the Water Quality Numbers Actually Say

Huntington Park runs its own municipal water system through the Water and Sewer Division at 6550 Miles Avenue. The system serves about 15,275 residents, which makes it a small operation by LA County standards. The city publishes an annual Consumer Confidence Report that tests for lead, heavy metals, chlorine, volatile organic compounds, PFAS, and radionuclides.

On the regulatory side, the water meets EPA maximum contaminant levels. That's the legal standard. But independent analysis from TapWaterData.com paints a more detailed picture. Out of 371 contaminants tested, 7 were detected above health guidelines set by groups like the Environmental Working Group. These health guidelines are stricter than the legal limits, so this doesn't mean the city is violating any rules. It does mean that if you're the kind of person who reads labels at the grocery store, you might want to read your water report too.

If you've lived in your home near Pacific Boulevard for a couple of decades and never thought twice about your tap water, now is a reasonable time to pay attention. Not to panic, just to get informed. A point-of-use water filter is a low-cost way to add protection while you wait for more information from the inventory program.

Old Pipes and Everyday Plumbing Problems

Here's how this connects to the stuff you'd actually call a plumber about.

Lead solder joints in pre-1986 homes aren't just a water quality concern. They're also a weak point in your plumbing system. Over 40-plus years, those joints can develop pinhole leaks. You might not even notice at first. A tiny drip behind a wall can go on for months before it shows up as a stain on your ceiling or a musty smell in your hallway.

Homes in Huntington Park's older blocks, particularly those near the Southern Pacific rail corridor and the neighborhoods between Salt Lake Park and Miles Avenue, were largely built during the postwar construction boom. That era produced solid, affordable houses. It also produced plumbing that was considered state-of-the-art in 1955 but is now 70 years old. Galvanized steel supply lines, cast iron drain pipes, and yes, copper with lead solder. All of it has a lifespan, and most of it has reached or passed that window.

If you've noticed low water pressure at your kitchen faucet, rust-colored water first thing in the morning, or your water heater seems to need flushing more often than it used to, the culprit could be corrosion and sediment buildup from aging pipes inside your own walls.

The City's Infrastructure Budget Tells a Story

Huntington Park's adopted FY2026 Capital Improvement Program includes money for well improvements and sewer system upgrades. That's worth paying attention to because it signals that the city knows its underground infrastructure needs work, and it's putting dollars behind that knowledge.

For homeowners, the practical takeaway is this: when the city starts replacing or repairing water mains and sewer lines in your neighborhood, it's a good time to have a plumber inspect your own service lateral and supply lines. Construction crews will already have the street open. If your lateral is cracked or your service line is corroded, coordinating your repair with the city's project can save you money on excavation and repaving.

The sewer lateral side of this is especially relevant. Huntington Park's sewer mains serve roughly 6,600 connections, and some of those mains are long overdue for rehabilitation. But remember, the city handles the public main. The lateral running from the main to your house? That's on you. A collapsed lateral can cause sewage backups into your home, and the repair often involves digging up your front yard or driveway. Getting a sewer camera inspection done before you have an emergency is one of the smartest preventive moves a homeowner can make.

What You Can Do Right Now

You don't need to rip out your walls this weekend. But there are a few practical steps worth taking.

First, find out if the city's lead service line inventory has reached your address yet. Check the LSLI program page for updates or contact the Water and Sewer Division directly at 6550 Miles Ave.

Second, if your home was built before 1986, run your cold water tap for about 30 seconds before filling a glass in the morning. That flushes out water that's been sitting in contact with your pipes overnight. It's a simple habit that costs you nothing.

Third, read your city's Consumer Confidence Report. It's published annually and it breaks down exactly what's in your tap water. Not exciting reading, but useful.

And fourth, if you haven't had a plumber do a full inspection of your supply lines and drain system in the last five years, consider scheduling one. Huntington Park's housing stock is old enough that surprises are common, and catching a slow leak or a corroding joint before it becomes a flood is always cheaper than the alternative.
