615 Septic Tank Pumping is a septic tank pumping company serving Nashville and Davidson County, Tennessee, and septic tank inspection is one of the services it provides across the county. A documented assessment of tank, baffles, filter and field condition — for owners who want to know where they stand rather than wait for a symptom.

When people call us about this

These are the situations that bring most septic tank inspection calls in:

  • No service records for the property
  • Buying land or a home and wanting the system assessed
  • Planning an addition or an extra bedroom
  • Recurring slow drains with no obvious cause
  • Wanting a baseline before a system reaches 30 years old

What is included

Every septic tank inspection job includes all of the following. Nothing on this list is an upsell presented once we are on site.

  • Tank located and both access points opened
  • Sludge and scum depths measured and recorded against tank capacity
  • Inlet baffle assessed for corrosion, displacement and blockage
  • Outlet baffle and effluent filter assessed, cleaned and reported
  • Tank structure checked for cracks, spalling, root intrusion and groundwater infiltration
  • Drain field walked for surfacing, ponding, odour and differential grass growth
  • Metro bedroom-approval record cross-checked against the property's actual bedroom count
  • Written report with photographs and a plain statement of what needs doing and when

What it costs, and what moves the price

Most pumpers check baffles as part of standard service at little or no extra cost; a standalone documented inspection is a separate, longer job.

The published range for this service is $225–$400 standalone, or $0–$50 as a baffle and filter check during routine pumping. We give you a band before we come out and a firm number before we do anything that changes it. If you want a figure right now without talking to anyone, the cost estimator takes three questions.

How septic tank inspection runs, start to finish

  1. 01

    Records first

    Before we open anything we check what Metro holds — approval date, inspection dates and the bedroom count the system was permitted for. That single record explains a surprising number of failing systems.

  2. 02

    Open and measure

    Both lids come off. Depths are measured against tank capacity, which tells us whether the tank is being serviced adequately for the load it actually carries.

  3. 03

    Assess the mechanicals

    Baffles and effluent filter are where a system fails quietly. A corroded outlet baffle sends solids to the field for years before anything shows at the house.

  4. 04

    Walk the field and report

    The field is walked for the early signs — soft ground, differential growth, faint odour. You get a written report with photographs rather than a verbal all-clear.

Doing it yourself, hiring cheap, and doing it properly

The difference between a cheap pump-out and a proper one is not the truck. It is whether anybody looked inside the tank while it was empty.

  Doing it yourself Cheapest quote Done properly
Solids actually removed Surface liquid only — no way to remove settled sludge Liquid draw-down; tank looks emptied, sludge stays Liquid, scum and sludge pumped, then backflushed
Baffles inspected Not visible without emptying the tank Rarely — the tank is not pumped down far enough to see them Both baffles inspected while the tank is empty, and reported
Effluent filter Usually not known to exist Left alone Removed, rinsed back into the tank, inspected, replaced if split
Interval set by Guesswork or a number off the internet A flat three years for every customer Measured sludge and scum depth against your tank capacity
Disposal of septage No lawful route for a homeowner Varies — ask where it goes Licensed disposal under Tennessee pumping contractor rules
What it costs Nothing up front Slightly less than proper $300–$525 typical
What it risks Solids reach the drain field. Field replacement $7,000–$15,000+ Same failure, delayed. The field pays for the saving The field is what you are protecting

Worth reading before you book

Rules & Permits

How many bedrooms is my Davidson County septic approved for?

Metro holds the record and will tell you. It affects what you can advertise, what you can add, and how often you should pump.

Rules & Permits

Does my lot have room to replace the septic if it fails?

A rule most owners have never heard of, that Metro says can in rare cases lead to a residence being condemned.

Rules & Permits

Do I need a permit to repair my septic system in Davidson County?

Davidson runs its own program on top of the state rules. What that means when you need work done.

Decision Guide

How do I know if my septic baffle has failed?

You almost certainly cannot tell from the surface — which is exactly why this failure is so expensive.

Septic Tank Inspection — questions people ask

How many bedrooms is my septic system approved for?

Metro Public Health holds that record and will tell you the approval date, inspection dates and permitted bedroom count for an existing residence. It matters more than most owners realise: the system was sized for that number, and Tennessee makes it illegal to advertise a residence for more bedrooms than its septic is approved for.

Does my lot have room to replace the system if it fails?

Tennessee requires a septic system to sit entirely within its own parcel with specific setbacks, and requires the parcel to retain sufficient area to replace the system should it fail. Properties that fail that second test create serious problems on sale, and Metro notes that on very rare occasions a residence may be condemned. We assess reserve area as part of a full inspection.

Is an inspection the same as a pump-out?

No. A pump-out empties the tank and includes a baffle check. An inspection is a documented assessment of the whole system — tank structure, mechanicals, field condition and records — producing a written report. Many owners have the tank pumped at the same visit because an empty tank inspects far better than a full one.

How long does an inspection take?

Around 90 minutes to two hours for a standard residential system, longer where lids are buried or the field is large. Standalone inspections take longer than the baffle check bundled into a routine pump-out, which is why they are priced separately.

How do you price the work, and will the price change once you are here?

You get a range before we come out, based on your tank size and how buried the lids are. Tennessee pumping runs $275–$525 and Davidson County figures span $199–$796, so the honest answer is that access and capacity move it. If we open the tank and find something that changes the job — compacted sludge needing a clean, a corroded baffle, a split effluent filter — we tell you what it costs and let you decide before we do it. We do not do the work and present the bill afterwards.
