Jacksonville is one of the most interesting cities in Florida when it comes to plumbing. And not always in a good way.
We’ve got homes built in the 1920s sitting next to homes built in 2020. We’ve got neighborhoods where every house has the same pipe problems because they were all built by the same developer in the same decade using the same materials. And we’ve got homeowners who have no idea what’s running under their slab or inside their walls until something goes wrong.
If you live in one of Jacksonville’s older neighborhoods, this post is for you. We’re going to walk through the most common plumbing issues we see in each area, what kind of pipes are probably in your home based on when it was built, and what you should be watching for before a small problem turns into a big one.
We’ve been working in these neighborhoods for years. This isn’t textbook stuff. This is what we actually see when we show up.
A Quick History of Pipes in Jacksonville
Before we get into neighborhoods, here’s the cheat sheet on pipe materials and when they were commonly used in Northeast Florida:
Cast iron (1920s through 1970s). Heavy, durable, and the standard for drain and sewer lines for decades. The problem is rust. Cast iron corrodes from the inside out over time. After 50 to 80 years, the walls thin, cracks develop, and sections can collapse entirely. If your home was built before 1975, there’s a very good chance you have cast iron somewhere in your system.
Galvanized steel (1930s through 1960s). Used for water supply lines. These pipes corrode internally, building up mineral deposits that restrict water flow over time. If you’ve noticed your water pressure getting worse year after year, galvanized pipes are often the reason. They also eventually rust through and leak.
Orangeburg pipe (1940s through 1970s). This one’s fun. Orangeburg is literally made of compressed tar paper. It was cheap, easy to install, and used for sewer lines. It was also never meant to last more than 50 years. If your home has Orangeburg, it’s either already failed or about to. We’ve pulled Orangeburg pipes out of the ground that were completely flat, crushed under the weight of the soil above them.
Polybutylene (1978 through 1995). A flexible gray plastic pipe used for water supply lines. It was marketed as the pipe of the future. Turns out, it reacts with chlorine and other chemicals in municipal water systems, becomes brittle, and cracks. If your home was built between the late 70s and mid 90s, check for gray flexible pipes under sinks and at the water meter. Insurance companies don’t love these.
PVC and CPVC (1970s to present). The modern standard. PVC for drain lines, CPVC for hot and cold water supply. These are what you want in your home. If your pipes are PVC, you’re in good shape for the foreseeable future.
PEX (1990s to present). Flexible plastic tubing used for water supply. Common in newer construction and remodels. Durable, affordable, and easy to work with. If someone repiped your home in the last 20 years, it’s probably PEX.
If your Jacksonville home was built before 1980, you almost certainly have at least one of the older pipe types somewhere in your system. The question isn’t if they’ll fail. It’s when.
Riverside and Avondale
These are some of Jacksonville’s most beautiful neighborhoods. They’re also some of the oldest. Homes in Riverside and Avondale range from the early 1900s through the 1960s, with a mix of bungalows, Tudor revivals, and mid-century ranches.
What we see: Cast iron drain lines that have been corroding for 60 to 100 years. Galvanized steel water supply lines with restricted flow. Root intrusion from the massive oak trees these neighborhoods are famous for. The root systems on those old oaks are aggressive and they find every crack and joint in underground sewer lines.
The most common call: Low water pressure (galvanized supply lines) and recurring drain backups (root intrusion into cast iron sewer lines).
What to watch for: If you’re getting your drains cleaned more than once a year in the same spot, the problem isn’t the clog. It’s the pipe. Roots keep coming back because the crack they’re entering through keeps getting bigger. A sewer camera inspection will show you exactly what’s going on down there.
We love working in Riverside and Avondale. The homes have character. The pipes have stories. Usually not great stories, but stories.
San Marco
San Marco homes are generally from the 1920s through the 1950s, with some newer infill construction. Similar to Riverside in age but with its own quirks.
What we see: Cast iron throughout, both drain and sewer. Many homes in San Marco have cast iron pipes running under the slab, which makes repairs more involved because you’re dealing with concrete on top of the pipe. We also see a lot of older water heaters in San Marco. Homeowners in these neighborhoods tend to stay for a long time, which means the water heater has been there for a long time too.
The most common call: Slab leaks. When cast iron pipes under the slab corrode and crack, water seeps into the foundation. You might notice a warm spot on your floor, a spike in your JEA bill, or the sound of running water when nothing’s on.
What to watch for: Any unexplained increase in your water bill. If JEA is suddenly $50 or $100 more than normal and your usage hasn’t changed, get a leak detection done before it gets worse. We’ve caught slab leaks in San Marco that would have caused tens of thousands in foundation damage if they’d gone another few months.
Springfield
Springfield is Jacksonville’s original suburb. Homes here date back to the late 1800s and early 1900s. Some of the oldest residential plumbing in the city.
What we see: Everything. Cast iron, galvanized, clay tile sewer lines, and occasionally lead supply lines in the oldest homes. Springfield homes have been renovated so many times over the decades that you’ll often find three or four different pipe materials spliced together in the same system. One section of cast iron connected to PVC connected to galvanized connected to something we can’t identify.
The most common call: Complete system failures. When a 120-year-old plumbing system has been patched and repaired for generations, eventually the patches can’t hold anymore. Full repipes are common here.
What to watch for: If you’re buying a home in Springfield, get a plumbing inspection. Not just a home inspection that includes plumbing as a checkbox. A dedicated plumbing inspection with a camera run through the sewer line. The cost of the inspection is nothing compared to what you’d spend if you buy a home with failing pipes and don’t know it.
Springfield homes are full of surprises. Some of them are charming. The plumbing surprises usually aren’t.
Arlington
Arlington was largely developed in the 1950s through the 1970s. These are your classic mid-century Florida ranch homes with slab foundations.
What we see: Cast iron drain lines under the slab, Orangeburg sewer lines running to the street, and some polybutylene water supply lines in homes built in the late 70s and 80s. Arlington is where we see the most Orangeburg pipe. It was cheap and the developers building hundreds of homes at a time used a lot of it.
The most common call: Sewer line collapses. Orangeburg literally flattens over time. The pipe goes from round to oval to flat. Once it’s flat, nothing’s getting through. We’ve dug up Orangeburg pipes in Arlington that looked like someone stepped on a paper towel roll.
What to watch for: Slow drains throughout the entire house, not just one fixture. If every drain in the house is slow, it’s probably the main sewer line, not individual clogs. Gurgling toilets when you run the washing machine is another sign the sewer line is struggling.
Mandarin
Mandarin developed through the 1970s, 80s, and 90s with continued growth today. It’s a mix of older established neighborhoods and newer subdivisions.
What we see: Polybutylene supply lines in homes from the early 80s through mid 90s. This is the biggest issue in Mandarin. Poly B pipes can look fine from the outside and be deteriorating from the inside. When they fail, they fail suddenly. One day everything’s fine, the next day you have a fountain in your ceiling.
The most common call: Sudden pipe bursts from polybutylene failure. Usually in the attic or inside walls. Water damage can be significant because homeowners don’t know there’s a problem until water is coming through the ceiling.
What to watch for: Check under your sinks. If you see gray flexible pipe (not white PVC, not red or blue PEX), that’s polybutylene. Some insurance companies in Florida have started requiring poly B replacement or won’t write the policy at all. If you’re selling a home with poly B, expect it to come up in the buyer’s inspection.
The Beaches (Jacksonville Beach, Neptune Beach, Atlantic Beach)
Newer construction overall, with homes ranging from the 1960s through today.
What we see: Corrosion. Salt air accelerates corrosion on exposed pipes, outdoor fixtures, and water heaters in garages. Water heaters at the Beaches have shorter lifespans than water heaters 20 miles inland because of the salt exposure. We also see more outdoor shower and hose bib issues here than anywhere else in Duval County.
The most common call: Water heater failure. Between salt air corrosion and Jacksonville’s hard water, water heaters at the Beaches take a beating from both sides.
What to watch for: Rust on your water heater, especially around fittings and connections. If the exterior is corroding, the interior is worse. Also, if your outdoor shower or hose bibs are dripping or hard to turn, get them fixed before they freeze during a cold snap and crack. Yes, it freezes at the Beaches. Not often, but enough.
How Do I Know What Pipes I Have?
You don’t need to crawl under your house or tear open walls. Here are three easy ways to find out:
1. Check the age of your home. The decade it was built narrows down the likely pipe materials significantly. Use the cheat sheet above.
2. Look under sinks and in the garage. Exposed pipes in these areas will tell you what’s running through the rest of the house. Gray and flexible? Polybutylene. White plastic? PVC or CPVC. Metallic and threaded? Galvanized steel. Dark and heavy? Cast iron.
3. Get a plumbing inspection. We can run a camera through your drain and sewer lines and tell you exactly what’s in there, what condition it’s in, and how much life it has left. A sewer camera inspection takes about an hour and gives you a complete picture of what’s happening underground.
You wouldn’t buy a car without checking under the hood. Same goes for a house. Know your pipes.
When Does It Make Sense to Repipe?
Not every old pipe needs to be replaced immediately. Cast iron that’s been in the ground for 60 years might have another 10 years in it. Or it might not. Here’s our general rule of thumb:
Repipe now if: You’re having recurring problems (multiple leaks, repeated backups, water pressure dropping), your insurance is requiring it, or the pipe material is known to fail (polybutylene, Orangeburg).
Plan for it if: Your pipes are past their expected lifespan but still functioning. Start budgeting and get an inspection so you know what you’re dealing with. Proactive replacement on your schedule is always cheaper and less stressful than emergency replacement on the pipe’s schedule.
Don’t worry about it if: You have PVC or PEX installed in the last 20 to 30 years. You’re good.
