Sewer Line Repair

What the Sewer Line Is and Who Owns Which Part

Every drain in your house ties into one main pipe under the slab. Plumbers call that the building drain. Once it leaves the foundation, it becomes the building sewer, which runs across your yard to either a septic tank or a public sewer connection.

The short run between your property and the main in the street is often called the lateral. Who owns what depends on the utility. In general, the homeowner is responsible for the pipe from the house out to the property line or the utility’s connection point, and the utility maintains the main and its side of the connection. Some utilities draw that line at a cleanout near the property line or right-of-way. If you’re not sure where your responsibility ends, we’ll help you find the connection point and check with your utility before any digging starts.

Common pipe materials in Southwest Florida

• Cast iron: standard in many homes built before the 1980s, especially under the slab.
• PVC: the usual material for building drains and sewers in newer homes and for most replacements today.
• Clay: less common here, but it shows up on some older properties and commercial sites.
• Orangeburg: a tar-paper pipe used decades ago. It’s rare in this area, but when we find it, it almost always needs to be replaced.

Signs of Sewer Line Trouble

A single slow sink is usually a local clog. Sewer problems tend to show up across the whole house at once, or in the lowest fixtures first.

• Several drains running slow at the same time
• Gurgling from a toilet when you run the washer or a tub
• Water coming up in the shower or tub when you flush
• Sewage smell inside the house or near the cleanout outside
• Soggy, unusually green or sunken spots in the yard along the sewer route
• Clogs that come back a few weeks after the line is cleared
• Cracks in floor tile or a damp spot on the slab with no water line nearby

Sewer gas has a rotten-egg smell from hydrogen sulfide. If you smell it indoors, start with the easy stuff. A dry floor drain or a shower that hasn’t been used in a while can let gas in through an empty trap. Run water in those fixtures. If the smell stays, there may be a cracked pipe, a failed seal at a toilet, or a break in the drain under the house, and it’s worth having it checked.

If a clog is the only symptom, our drain cleaning service may be all you need. When the same line keeps backing up, that usually points to something wrong with the pipe itself.

What Causes Sewer Line Problems in Southwest Florida

Our soil, water table and weather create a specific set of problems. These are the ones we run into most.

Aging cast iron

Cast iron drain pipe corrodes from the inside. Gases in the sewer line and our humid climate speed that up. Over time the bottom of the pipe can wear through and form a channel, and scale builds up that catches paper and grease. It’s one of the biggest reasons older homes here have repeat backups.

Tree and shrub roots

Roots go after water and nutrients, and a sewer line has both. They get in at joints and small cracks, then grow into a mat that catches everything flowing past. Clearing roots helps for a while, but they come back if the opening is still there.

Sand, settling and shifted pipe

A lot of SWFL lots are sandy fill over a high water table. When soil settles or gets washed out by heavy rain or storm surge, a section of pipe can drop and form a belly, a low spot where water and waste sit. Joints can also pull apart and create an offset, where one pipe end no longer lines up with the next. After major storms, we also see sand and silt inside lines that were damaged or flooded.

Collapsed or crushed pipe

Heavy equipment, a new driveway, or just age can crush a line. Once a section collapses, nothing gets through, and the fix is replacing that part of the pipe.

Camera Inspection: Seeing the Problem Before We Dig

We don’t guess with sewer lines. A camera on a flexible cable goes in through a cleanout or other access point and sends back live video of the inside of the pipe. We can see roots, cracks, bellies holding water, offset joints, scale in cast iron, and anything that doesn’t belong there.

Most cameras also carry a locator, so we can mark on the ground where the problem is and how deep it sits. That tells us whether it’s a small repair in the yard or something under the slab, and it keeps digging to the spot that actually needs it.

A camera inspection is also smart before you buy an older home, before a remodel that adds bathrooms, or after a storm when the drains don’t seem right. If we’re already working on a slab leak or other issue through our leak detection service, we may recommend looking at the drain line at the same time.

Sewer Line Repair and Replacement Options

The right repair depends on what the camera shows, how much of the line is bad, what it’s made of, and where it runs. Here’s how we usually break it down.

Spot repair

If there’s one cracked joint or one root intrusion and the rest of the pipe is in decent shape, we can dig at that location, cut out the damaged piece, and put in new pipe with proper couplings. It’s the least invasive option when it fits.

Section replacement

A belly or a run of cracked clay usually needs more than a patch. We’ll replace that stretch, set it back on proper grade, and bed it so it doesn’t sink again.

Full replacement

When the whole line is failing, or you’ve paid for one spot repair after another, it often makes more sense to replace the building sewer from the house to the connection point. New PVC with correct slope and cleanouts gives you a line you can maintain.

Trenchless methods

There are trenchless ways to rehab a sewer line, like pipe lining and pipe bursting, that need only small access pits. They can be a good choice under a driveway, pool deck or mature landscaping. They don’t work for every line. A pipe with a severe belly, heavy collapse or tight bends may not be a candidate. We’ll tell you whether it’s an option for your line and what the tradeoffs are.

Cast Iron Drains Under the Slab

Most Florida homes sit on a concrete slab, and in older houses the cast iron drains run right under it. When those pipes deteriorate, you can’t see it happening. The signs are backups, a sewer smell, cracked tile, or a camera showing a channeled bottom or heavy scale.

There are a few ways to handle it. We can open the floor at the problem area, tunnel under the foundation from outside, or reroute the drain in some cases. If the cast iron is failing throughout the house, replacing the whole under-slab system may be the better long-term answer. That’s a bigger project, and it often gets paired with a whole-house repipe of the water lines so the floors only get opened once.

We’ll show you the camera footage, explain what we see, and walk you through what each option means for your floors, your timeline and your use of the house during the work.

Cleanouts: Why They Matter and Adding One

A cleanout is a capped fitting that gives direct access to the drain or sewer line. It’s how we get a cable or camera into the pipe without pulling a toilet or cutting into anything.

Plumbing code calls for cleanouts at set points, including near where the building drain meets the building sewer and at regular intervals on long sewer runs. Many utilities also want a cleanout near the property line or at the connection point. Some are installed as two-way cleanouts, which let you access the line in both directions.

Plenty of older homes have no outdoor cleanout at all, or one buried under sod or a paver patio. We can locate an existing cleanout, raise one to grade, or add a new one. It’s a small job that makes every future repair faster and less messy.

Septic Homes vs. Sewer Homes

A lot of Southwest Florida still runs on septic. In a septic home, the building sewer carries waste to a tank on your property, and the tank drains to a drainfield. In a sewer home, the line runs to a public connection and the utility takes it from there.

We work on the building sewer in both cases. That’s the pipe from the house to the septic tank inlet, or from the house to the public connection. We don’t pump septic tanks or repair drainfields. That’s septic contractor work, and if your problem turns out to be in the tank or the field, we’ll tell you so you can call the right company.

Septic-to-Sewer Conversions

Several parts of our area are in the middle of moving homes off septic and onto central sewer. Cape Coral has been extending utilities neighborhood by neighborhood, and there have been conversion projects and studies around Fort Myers, North Fort Myers and Lehigh Acres. When sewer becomes available on your street, your utility will send notice with a deadline to connect. In Cape Coral, for example, owners are given 180 days from the notice of availability. If you’re in one of those areas, our Cape Coral, Lehigh Acres and Fort Myers pages have more local detail.

How a conversion usually goes

• You apply with the utility and pay its connection fees. The utility will usually ask for your plumber’s name.
• We pull the plumbing permit for the sewer connection and the septic abandonment.
• We disconnect the building sewer from the septic tank and run new pipe to the utility’s connection point, with cleanouts where required.
• The trench stays open until the utility or building department inspects the new line.
• The old tank gets pumped by a licensed septage hauler, then collapsed and filled so it can’t hold water again.
• The health department inspects the abandonment. Once everything passes, we backfill and restore the area.

Septic abandonment

Florida rules require an old septic tank to be properly abandoned once a property connects to sewer. The tank usually doesn’t have to be removed. It has to be pumped, then broken or collapsed so it can’t hold water, and filled with clean sand or other suitable fill. In Lee County, the health department expects this done within 90 days of connecting, with its own permit and inspection. We handle the abandonment work on the tank as part of the conversion, and we coordinate the pump-out with a licensed hauler.

Every utility has its own paperwork, fees and inspection steps. We’ll go over what yours requires before we start so there are no surprises on inspection day.

New Sewer Installation for New Construction

On a new home or building, the sewer line is part of the underground rough-in. We lay out the building drain before the slab is poured, set the pipe on correct grade, add cleanouts where code and the utility require them, and run the building sewer to the public tap or the septic tank.

Getting grade right at this stage matters. A line that’s too flat or has a low spot will give the owner trouble for years. We coordinate with the builder, the site work crew and the inspector so the sewer ties in cleanly. Our new construction plumbing page covers the rest of the rough-in and trim work.

We also add sewer connections for additions, detached buildings and major remodels. If a renovation is adding a bathroom or moving a kitchen, we’ll check whether the existing line can handle it.

Backups After Heavy Rain and Storms

When a summer storm or tropical system dumps a lot of rain, public sewer systems can get overloaded as groundwater and stormwater find their way into the pipes. If the sewer main backs up past the level of your lowest drain, wastewater can come up into your house. Septic homes see a version of this too when a saturated drainfield stops accepting water.

A backwater valve is a check valve on the sewer line that lets wastewater flow out but closes when flow tries to reverse. Plumbing code requires one where fixtures sit lower than the next upstream manhole cover on the public sewer. They’re also worth considering on low lots and homes that have backed up during storms before. A backwater valve needs an accessible spot and occasional checking to keep working.

After a hurricane or flood, it’s a good idea to run a camera through the line if drains are slow or you notice a smell. Storm surge and saturated ground can shift pipe, and sand can wash into a broken line.

Commercial Sewer Lines

Restaurants, retail spaces, offices and multifamily buildings put more demand on a sewer line than a single house does. Grease, heavy use and long runs to the main mean problems build faster and hit harder when they show up. We handle camera inspections, repairs, replacements and new connections on commercial properties, and we can schedule work to limit how long a business is down. See our commercial plumbing page for more.

What to Do During a Sewer Backup

• Stop using water. Don’t flush, run the dishwasher, or do laundry until the line is clear.
• Stay out of standing sewage and keep kids and pets away from it.
• If you can find your outdoor cleanout safely, loosening the cap slowly can relieve pressure so waste comes out outside instead of inside. Stand to the side, since it may spray.
• Don’t pour chemical drain cleaners into a backed-up line. They rarely clear a sewer blockage and make the job harder for whoever opens it.
• Take photos for your insurance company before cleanup.
• Call a plumber to clear the line and find out why it backed up.
