Septic tank inspections are a critical part of maintaining a properly functioning septic system. Regular inspections can catch problems early before they lead to costly repairs or system failure. Here are answers to some of the most frequently asked questions about septic tank inspections.
Key Takeaways
- Septic tank inspections should be done every 1-3 years
- Inspections check the tank, drainfield, and other system components
- Warning signs of septic problems include foul odors, slow drains, and soggy spots in the yard
- Inspections are required when buying or selling a home with a septic system
- Costs range from $200-$600 depending on the type of inspection
Why Are Septic Tank Inspections Important?
Your septic system handles all the wastewater from your home, including from toilets, sinks, showers, and appliances. Over time, sludge builds up in the tank and needs to be pumped out. The drainfield can also become clogged, preventing wastewater from properly draining.
Regular septic tank inspections allow you to:
- Identify problems early, before they cause backups or system failure
- Avoid costly repairs from neglected maintenance
- Ensure your system is functioning properly to protect your property value
- Prevent contamination of groundwater and nearby water sources
How Often Should I Get My Septic Tank Inspected?
Most experts recommend getting your septic tank inspected every 1-3 years, depending on the size of your tank, number of people in your household, and amount of wastewater generated. More frequent inspections may be needed for older systems.
You should also get an inspection if you notice any signs of septic system problems, such as:
- Foul odors in your yard
- Slow drains or gurgling sounds in pipes
- Soggy spots or standing water in the drainfield area
- Sewage backup into your home
What Happens During a Septic Tank Inspection?
A typical septic tank inspection includes a visual check of the tank, drainfield area, and other system components. The inspector will measure the levels of sludge and scum in the tank to determine if pumping is needed.
Here is an overview of what an inspector looks for:
| System Component | What is Checked |
|---|---|
| Tank | Sludge and scum levels, signs of leaks or cracks, condition of baffles |
| Drainfield | Even distribution, soggy areas, odors, trees or roots, pavement over the top |
| Distribution box | Levelness, equal distribution to drainfield lines |
| Pipes | Leaks, cracks, corrosion |
For a more thorough inspection, the tank may need to be pumped out. Once empty, the inspector can check the inside for cracks or damage. A dye test may also be performed, where dye is flushed through the system to check for leaks.
Are Septic Tank Inspections Required?
Septic tank inspections are typically required in two situations:
- Buying or selling a home with a septic system
- When applying for a building permit for a remodel or addition
Most lenders require a septic system inspection before approving a mortgage on a property with a septic tank. This protects the buyer from inheriting a faulty system and the lender from financing a property with a major defect.
Some counties also require periodic septic system inspections to ensure proper functioning and prevent groundwater contamination. Check with your local health department for requirements in your area.
How Much Does a Septic Tank Inspection Cost?
The cost of a septic tank inspection ranges from about $200 to $600, with most homeowners paying around $300-$400. Factors that affect the cost include:
- Size of the tank
- Type of system
- Soil conditions
- Accessibility of the tank and components
- Whether pumping is required for the inspection
Some inspectors charge a flat rate, while others charge by the hour. Be sure to ask upfront what is included in the price and whether there are any additional costs for services like pumping the tank.
What Happens if Problems Are Found During the Inspection?
If the inspector finds any damage or malfunctions, they will recommend repairs or replacement of the affected components. Minor repairs, like fixing a broken baffle or distribution box, may cost a few hundred dollars. Major problems, like a cracked tank or failing drainfield, can cost thousands of dollars to repair or replace.
If you are buying a home with a septic system, you will need to negotiate with the seller about who pays for any needed repairs. You may be able to get the seller to fix the problem before closing or offer a credit towards the repair costs. If you are selling your home, you will need to disclose any known problems with the septic system to potential buyers.
Maintaining Your Septic System Between Inspections
Regular septic tank inspections are important, but there are also things you can do to maintain your system between service visits:
- Watch what goes down the drain. Avoid putting grease, oil, coffee grounds, cigarette butts, paper towels, and other hard-to-break-down items in your sinks or toilets.
- Use water efficiently. Fix leaky faucets and toilets, run full loads in the dishwasher and washing machine, and don’t let the water run unnecessarily.
- Space out laundry and dishwasher loads. Doing all your loads back-to-back can overload your septic system with too much water at once. Allow time between loads for the system to recover.
- Don’t pour chemicals down the drain. Harsh drain cleaners, paints, solvents, and other chemicals can disrupt the delicate ecosystem in your septic tank.
- Protect your drainfield. Don’t drive or park on the drainfield, plant trees nearby, or cover the area with concrete or asphalt. Keep excess water from rain gutters and sump pumps away from the drainfield.
Septic System Inspection Requirements by Loan Type
If you are buying a home with a septic system, the type of mortgage you get can affect the septic inspection requirements. Here is a breakdown of common loan types and their septic system rules:
| Loan Type | Septic Inspection Requirements |
|---|---|
| FHA | Inspection required, system must meet HUD guidelines |
| VA | Inspection required if the system is older, failing, or missing maintenance records |
| USDA | Inspection required, system must meet state and local codes |
| Conventional | Varies by lender, but often required, especially for older systems |
In most cases, if the septic system does not pass inspection, repairs will need to be made before the loan can close. Be sure to discuss septic inspection requirements with your lender early in the buying process.
Hiring a Qualified Septic Tank Inspector
Not all septic system inspectors are created equal. To ensure you get a thorough and accurate assessment, look for an inspector who:
- Is licensed and certified in your state
- Has experience with the type of septic system on your property
- Uses proper safety gear and follows industry standards
- Provides a detailed written report with photos
- Is insured in case of accidents or damage during the inspection
A good place to start your search is by asking for referrals from your local health department, real estate agent, or neighbors who have had good experiences with septic inspectors. You can also check online reviews and ratings from sources like the Better Business Bureau.
The Bottom Line on Septic Tank Inspections
