What Is Included in Basin Replacement

A basin replacement covers the pit itself and the parts that touch it. Here is what is in the standard scope and what we handle as an add-on when we find it.

  • New Basin and LidWe supply and set a new sump basin liner sized to your pump, with a gasketed lid. Standard sizes are 18-inch and 24-inch. The lid gets sealed and the pipe penetrations get gaskets so the pit stays closed.
  • Base Prep and GravelWe remove the old gravel and silt, check for voids, and set the new basin on compacted gravel. If the soil is washing in, we add filter fabric. This is the step that keeps the new liner from cracking.
  • Pump ReconnectionWe pull your existing pump, clean it, and reinstall it in the new basin. If the pump is failing, we tell you and quote a replacement. We set the float switch to the correct trip level for the new depth.
  • New Check ValveEvery replacement gets a new check valve. It stops water from draining back into the pit and short-cycling the pump. We test it during the fill test before we leave.
  • Discharge Line ReconnectionWe reconnect the PVC discharge pipe and check the slope and the exterior outlet. If the line is clogged or broken, we quote a repair or a new run. The pump has to move water away from the foundation to matter.
  • Live Fill TestWe fill the pit with a hose and watch the full cycle. The float switch trips, the pump runs, and the water leaves through the discharge line. You watch the test with us. If it does not pump down clean, we fix it before we pack up.

What Sump Pump Basin Replacement Naples FL Involves

Sump Pump Basin Replacement Naples FL is a drainage repair that removes a failed sump basin or pit liner and sets a new, sealed basin sized for your pump, inflow rate, and water table. We cut out the old liner, clear the gravel and silt, check the perforated drain pipe feeding the pit, then set the new basin on a compacted bed. The pump, float switch, check valve, and discharge line get reconnected and tested. Most homes are done in one day.

Naples sits on a high water table, and that is hard on pits. Thin plastic liners crack, concrete pits spall, and sandy soil shifts under the floor. Once the basin leaks, the pump runs constantly and never catches up. If you have been searching sump pump basin replacement near me Naples, the fix is usually the basin itself, not another pump. We see this most in homes built before 2005 and in low-lying parts of East Naples and Golden Gate.

A basin that holds water is what makes the pump last.

How Our Basin Replacement Process Runs

Five steps, one visit for most homes. Here is exactly what happens from the first call to the final test.

  1. Call and Assess

    Call and Assess

    You call, we ask three questions: how often the pump runs, whether the pit holds water after the pump shuts off, and how old the basin is. That tells us whether you need a full replacement or just a new float switch. We schedule a same-day estimate across Naples and Collier County.

  2. Drain and Cut Out

    Drain and Cut Out

    We kill power at the breaker, pull the pump and discharge line, and pump the pit down. Then we cut the old liner free and lift it out. Expect 45 to 90 minutes for this step on a standard 18-inch basin. We lay drop cloths and bag the debris as we go.

  3. Prep the Pit

    Prep the Pit

    We dig out silt and roots, check the perforated drain pipe for crush damage, and re-level the base with compacted gravel. If the surrounding soil is washing in, we add filter fabric. This is the step most quick replacements skip, and it is why their basins crack again within two years.

  4. Set the New Basin

    Set the New Basin

    We set the new liner, plumb it level, and seal the inlet and discharge penetrations with gasket and sealant. Then we reinstall the pump, a new check valve, and the PVC discharge pipe. A Wayne or Little Giant submersible drops straight in on most jobs.

  5. Test and Walk Through

    Test and Walk Through

    We fill the pit with a hose, watch the float switch trip, and confirm the discharge line carries water clear of the foundation. Then we show you the test and hand over the paperwork. Total job time runs three to five hours for a single basin.

Tools and Methods We Use

  • Submersible Utility Pump

    We use it to drain the old pit down before we cut the liner out. It handles the silt-heavy water that a standard shop vac cannot.

  • Basin Liners (18-inch and 24-inch)

    We stock both sizes on the truck. The right one depends on your pump body, switch range, and whether you plan to add a backup.

  • Zoeller and Liberty Pumps Units

    These are the submersible pumps we install most. We match the basin depth to the pump's float swing so the switch trips at the right level.

  • PVC Discharge Pipe and Check Valve

    We plumb the discharge in PVC with a new check valve. The valve stops backflow and the pipe carries water clear of the foundation.

  • Float Switch Test Rig

    We use it to confirm the switch trips and resets at the correct water levels in the new basin. A switch that hangs up is the number one cause of a dry pit flood.

  • Filter Fabric and Compacted Gravel

    We line the pit base with fabric and compact gravel under the new basin. That stops sandy Naples soil from washing in and shifting the liner.

  • Florida Building Code compliance

    We set the basin, lid, and pipe penetrations to meet Florida Building Code for sump pits. That includes a sealed lid and proper venting where the code calls for it. It keeps the inspection clean and the pit closed.

  • NEC electrical code disconnect

    We kill power at the breaker and keep the cord connection above the flood line per NEC electrical code. The pump gets a proper disconnect and a sealed cord entry. No exposed splices sitting in water.

When Naples Homeowners Replace a Basin

  • The pit is original to a 1990s home in East Naples and the liner flexes when you press it.

    We cut out the old liner, check the drain pipe, and set a new 18-inch basin on compacted gravel. We reuse the pump if it tests well and install a new check valve. The pit holds water between cycles and the pump stops short-cycling. Most homeowners get another decade out of the new basin.

  • A storm flooded the pit and the pump ran for two days straight. Now it will not turn on.

    We pump the pit down, test the float switch, and find the basin cracked from the load. We replace the basin and the failed float switch, then run a live fill test. The system cycles normally again. We also check the discharge line to make sure the next storm does not repeat the problem.

  • You are adding a battery backup system and the existing pit has no room for a second float.

    We replace the basin with a 24-inch liner, set the primary float higher and the backup float lower, and mount the battery box on a dry, sealed lid. The backup only runs when the primary fails or the power drops. Both pumps fit without the floats tangling.

  • A home inspection before closing flagged a cracked basin and a slow-draining pit in Port Royal.

    We document the old liner with photos, replace the basin, clear the perforated drain pipe, and re-test the full cycle. We provide the report the buyer needs. The inspection item clears and the closing stays on schedule. The new owner starts with a sound pit and a tested pump.

How Basin Replacement Runs in Naples

Naples sits on a high water table, and that shapes every basin job we do. In low-lying areas near the water, like Royal Harbor and Aqualane Shores, the pit can fill faster than a standard pump can clear it. We size the basin and the pump to the inflow, not to a generic spec sheet. Inland in Golden Gate and Pine Ridge, the issue is more often sandy soil shifting under the slab, which cracks liners at the inlet. We dig out the loose material and set the new basin on compacted gravel with filter fabric. Summer is our busy season. Afternoon storms dump two inches in an hour, and that is when failing pits show themselves. If you have been looking for sump pump basin replacement for older pits Naples Florida, we handle the full job: cut out the old liner, check the perforated drain pipe, set the new basin, and test it. We work to Florida Building Code and NEC electrical code, and we pull permits when the scope calls for it. Most homes are done in a single visit.

  • Old NaplesOlder homes with original concrete or thin plastic pits. Many basins here are past 15 years and crack at the inlet.
  • Royal HarborWaterfront lots with a high water table. Pits here fill fast, so basin depth and pump sizing matter more than usual.
  • Golden GateSandy soil that shifts with the water table. Basins set without a compacted gravel bed tilt and crack within a few seasons.
  • Pelican BayMid-rise and condo buildings with shared drainage. Basin replacements here often need coordination with the building's maintenance schedule.
  • High water table near the coastThe pit refills quickly, so the pump cycles more. We size the basin and pump to the inflow rate and set the float higher to reduce cycling.
  • Sandy, shifting soil inlandLoose soil washes into the pit and tilts the liner. We compact the base and add filter fabric to keep the new basin stable.

From problem to finished result.

  • Cracked 1990s Basin in East Naples

    Before

    An original plastic liner was cracked down one side and flexed under hand pressure. The pump ran every ten minutes even in dry weather because water drained back around the liner. Silt had built up six inches deep in the pit.

    After

    We cut out the old liner, removed the silt, and set a new 18-inch basin on compacted gravel with a new check valve. Run time dropped from constant to about four cycles per storm. The pit now holds water between cycles.

    Flush the pit and test the float switch once a year, ideally before hurricane season. Keep debris out of the pit and check the discharge outlet after heavy storms.

  • Flooded Pit After a Storm in Golden Gate

    Before

    A summer storm dumped two inches in an hour. The pump ran for two days straight and then stopped. The basin had cracked at the inlet from soil shifting under the slab, and the float switch had hung up on the discharge line.

    After

    We pumped the pit down, replaced the basin and the failed float switch, and re-routed the discharge line clear of the float. The live fill test ran clean. The system has cycled normally through two storms since.

    Check the discharge line for clogs each spring and make sure the float swings free. A stuck float is the most common cause of a dry pit flood.

  • Adding Backup Room in Pelican Bay

    Before

    A condo owner wanted a battery backup system, but the existing 14-inch pit was too crowded. The primary float caught on the discharge pipe, and there was no room for a second float. The basin was also showing hairline cracks.

    After

    We set a new 24-inch basin, set the primary float higher and the backup float lower, and mounted the battery box on a sealed lid. Both pumps now fit with clearance and the backup only runs when the primary fails.

    Test the backup pump twice a year by lifting its float by hand. Replace the battery every three to five years and keep the lid sealed.

Problems a New Basin Solves for Naples Homes

Most sump problems trace back to the pit, not the pump. These are the ones we see most in Naples and how a replacement fixes them.

  • Pit will not hold water after the pump shuts off

    Pit will not hold water after the pump shuts off

    We cut out the leaking liner, prep the base, and set a sealed basin with a new check valve. The pit holds water between cycles, so the pump rests. Most homeowners see run time drop from constant to a few cycles per storm. Water drains back around the liner, so the pump short-cycles all night. That burns out the motor years early and drives up your power bill.

  • Cracked or crumbling basin liner

    Cracked or crumbling basin liner

    This is the classic sump pump liner replacement for cracked basin Naples FL job. We remove the failed liner, clean out the silt, and set a new one on compacted gravel. We also check the perforated drain pipe while the pit is open. A cracked liner lets groundwater and soil into the pit. Silt builds up, the float switch hangs up, and the pump eventually fails during a storm.

  • Basin too small for the pump and backup

    Basin too small for the pump and backup

    We size the new basin to the pump's switch range and leave room for a second float. A 24-inch basin fits a submersible pump, a check valve, and a battery backup system with clearance. We set the primary float higher and the backup lower. A crowded pit means the float switch catches on the discharge line or the pump body. The pump either runs dry or never turns on. Adding a backup is impossible.

  • Sandy soil shifting under the slab

    Sandy soil shifting under the slab

    We dig out the loose material, compact a gravel bed, and set the basin level. If the surrounding soil is washing in, we wrap the pit with filter fabric. That stops the movement that cracks liners. Naples soil moves with the water table. A basin set on loose sand tilts, cracks at the inlet, and leaks. You get water at the pit edge after every heavy rain.

A sealed basin stops short-cycling and keeps the pit dry.

  • Pump Stops Short-Cycling

    A leaking basin lets water drain back around the liner, so the pump kicks on every few minutes. Once the new basin is sealed and the check valve holds, that cycling stops. Homeowners in Park Shore and Coquina Sands often see run time drop from constant to a few cycles per storm.

  • Correct Depth and Diameter

    We size the basin to the pump's switch range, usually 18 to 24 inches deep and 18 inches across for a submersible unit. Too shallow and the float switch trips early. Too narrow and a Zoeller or Liberty Pumps unit will not fit with the discharge line and cord clear of the float.

  • Code-Correct Lid and Seal

    Florida Building Code and NEC electrical code both apply to a sump pit. We set a gasketed lid, seal the pipe penetrations, and keep the cord connection above the flood line. That keeps radon and moisture out of the living space and keeps the electrical inspection clean.

  • Room for a Backup System

    A new basin gives you space for a battery backup system or a water-powered backup pump. On a two-pump setup we set the primary float higher and the backup lower, so the backup only runs when the primary fails. That layout is hard to fit into an old, crowded pit.

What Basin Replacement Costs in Naples

Typical 2026 pricing for a basin replacement in Naples runs $650 to $1,800. The low end is a straight 18-inch liner swap with a new check valve and labor. The high end is a 24-inch basin with a new submersible pump, discharge line work, and a permit. Cracked concrete pits, crushed drain pipe, and tight crawl space access add labor. We give you a written range before we cut anything, and we tell you if a repair makes more sense than a replacement. If you have been quoted a sump pump basin replacement service Naples FL price that seems high, call us for a second number.

What your estimate is based on

  • Basin size and materialAn 18-inch plastic liner costs less than a 24-inch basin or a concrete pit. Larger basins take more labor to set and more gravel to bed. The size you need depends on your pump and whether you plan to add a backup.
  • Pump replacementIf your pump tests well, we reuse it and the price stays low. If it is failing, a new submersible unit adds to the bill. We test the pump before we quote so you are not paying for a pump you do not need.
  • Discharge line conditionA sound PVC discharge line gets reconnected at no extra cost. A clogged or broken line needs repair or a new run, which adds labor and materials. We check it while the pit is open.
  • Drain pipe and base prepIf the perforated drain pipe feeding the pit is crushed, we replace that section. If the base needs extra gravel or filter fabric, that adds time. Skipping this step is why cheap replacements fail early.
  • Access and permitA pit in an open utility room is a quick job. A pit in a tight crawl space takes longer. If the scope requires a permit, that adds a fee. We tell you upfront whether a permit is needed.

$650 - $1,800 depending on basin size, pump condition, and discharge line work A new basin stops the short-cycling that burns out pumps and the leaks that flood floors. Most homeowners get a decade or more out of a properly set basin, which is far less than the cost of one flooded room.

Basin Versus Pump: Which One Failed

A pump that runs constantly is usually a basin problem, not a pump problem. Here is how to tell the difference before you buy a new pump.

  • Check the water level

    Fill the pit and watch. If the water drops after the pump shuts off, the basin or check valve is leaking. A sound pit holds its level.

  • Press the liner

    Push on the basin wall. If it flexes or you feel cracks, the liner is done. A solid basin will not move under hand pressure.

  • Watch the float

    Lift the float by hand and let it drop. If the pump does not start, the switch is bad. If it starts but the pit refills fast, the basin is the issue.

What Naples Homeowners Say

  • Our pit was original to the house and the liner was cracked all the way down one side. The pump ran every ten minutes even when it was dry out. They cut the old basin out, set a new one, and replaced the check valve. It has been through two storms since and the pump cycles maybe four times a night now. Clean work, drop cloths everywhere.
    Dana R.Homeowner, Old Naples
  • We had water coming up around the pit after every heavy rain. I thought we needed a bigger pump. They showed me the basin was leaking and the drain pipe was half crushed. They replaced the basin, fixed the perforated pipe, and re-tested it with a hose. No water on the floor since. Fair price and they explained everything.
    Miguel S.Homeowner, Golden Gate
  • I manage several units and two of them had failing basins. They replaced both in one day and set them up so a battery backup could be added later. They sent photos of the old liners so I could show the owners what failed. That kind of documentation makes my job easier. I have used them on three more units since.
