Get Eyes On it Before You Buy: Florida Real Estate Septic Inspections
The Cleanout (Scope Access)
The Fork In The Road
This is the primary access point for the sewer scope. In Florida, these are often buried under St. Augustine grass or mulch. If this cannot be found, inspectors may have to pull a toilet (risky) or go via the roof (limited visibility). Locating this before the inspector arrives saves time and ensures a full scope.
| Missing Cap | Allows rainwater or debris into the system. In Florida storms, this causes Hydraulic Overload (flooding the drainfield) and Lizard/Frog Intrusion. |
| Staining | Residue on the cap underside or threads indicates Past High Water Events. This suggests the system has backed up previously—ask the seller for details. |
| Obstructions | Vegetation, pavers, or concrete poured over the cleanout. This is a code violation in many FL counties and hinders emergency access. |
| Hand Tight Cap | The cap can be removed without tools. This is ideal for emergency relief during a backup, preventing sewage from entering the shower/tub. |
| PVC | Plastic cleanouts are the modern standard. Cast iron cleanouts (common in pre-1980 Florida homes) often have jagged internal corrosion that catches paper. |
"Ensure you have the tool to open this. It acts as an emergency relief valve. If the toilets ever start gurgling, remove this cap. If you see water standing here, the issue is the Septic System (outside). If it is dry, the clog is inside the house."
Tank Integrity & Location
Pump & Inspect
An inspection isn't complete without a pump-out. You need to see the physical walls of the tank. Important: In Florida's high water table, a cracked tank doesn't just let sewage out; it lets groundwater in (Infiltration). This constantly floods the drainfield, leading to premature failure.
- Sludge Level: Indicates maintenance history. Thick sludge means the seller deferred maintenance.
- Low Water Level: Indicates the tank is leaking. This is an environmental hazard.
- High Water Level (Over baffle): Indicates the drainfield is not accepting water. This is a "Red Flag" for system failure.
- Filter Check: Is there a filter on the outlet baffle? These protect the drainfield from solids.
- Risers: Are the lids at surface level? Digging up lids in Florida heat is difficult; risers add resale value and prevent damage to the yard during maintenance.
Request photos of the tank location relative to the house. Buyers often want to install pools or pavers later—knowing the tank location prevents costly surprises during future permitting.
Pump & Alarm Controls
Mounded Systems (Lift Stations)
Many Florida homes require "Mounded" systems due to the high water table. There must be a minimum separation between the bottom of the drainfield bed and the water table to allow for the discharge to perc. When this is not met the system is raised into a mounded drain field. These rely on electric pumps as gravity can no longer be achieved from the septic tank to the drain field. A tripped breaker during a hurricane cuts the alarm and the pump, leading to a silent backup.
- Alarm: Must be Visual (Red Light) AND Audible (Buzzer). Test this!
- Panel Location: Is the breaker accessible? GFCI breakers often trip during lightning storms.
- Weatherproofing: Ensure plug boxes have intact covers. Ants and lizards often nest in warm pump boxes, causing shorts.
Show the client the pump plug location. If the outlet fails, they can run an extension cord to the pump to keep the system running temporarily until an electrician arrives.
Drainfield Viability
The Big Ticket Item
The drainfield is the most expensive part to replace ($8,000 - $15,000+ in FL). It assesses current health but cannot guarantee future life, especially in sandy soils where "Biomat" can seal the ground suddenly.
If the home is Vacant, the drainfield is "rested" and dry. It may pass a visual inspection today but fail 3 weeks after a family moves in. Always request a Hydraulic Load Test where the inspector introduces hundreds of gallons of water to stress-test the field.
Does the client want a pool or guest house? In Florida, setback rules are strict (usually 75ft from well, 5ft from property line, 5-10ft from house). Verify the drainfield location doesn't kill their future backyard dreams.
