Understanding Septic Systems: A Detailed Guide to Inspections

Regarding homeownership, certain responsibilities might seem a bit like a visit to the doctor—an essential checkup for the health of your property. One such vital examination is a septic system inspection. This guide delves deep into “What Does a Septic Inspection Entail”, from the basics to the details, ensuring you’re well-prepared for homeownership.

Septic Systems and Rural Living: A Symbiotic Connection

Rural life offers numerous benefits, but it comes with the responsibility of maintaining your septic system. Unlike urban areas with convenient city water and sewer connections, rural homes often rely on a “well and septic” system. Roughly one in five households nationwide depend on a well and septic system for water supply and wastewater disposal, respectively. The U.S. Environmental Protection Agency (EPA) recommends inspections every one to three years for such systems.

Types of Septic Systems: Conventional and Alternative

Septic systems come in two basic types: conventional and alternative. Traditional systems can be further categorized as gravity or pressure distribution systems. Gravity systems rely on the natural force of gravity to move effluent through the Tank and into the leach field, while pressure distribution uses a pump for even distribution.

Alternative systems, such as the Aerobic Treatment Unit, Mound System, and Sand Filter System, cater to specific needs, such as environmental sensitivity or limited soil availability. Understanding the type of system you have is crucial for determining the inspection frequency.

What Triggers the Need for Inspection?

Whether you plan to list your property or ensure your septic system’s well-being, understanding the scenarios that necessitate an inspection is crucial.

Inspection Elements: Unveiling the Mysteries

Ingrid Williams, a top agent in Iowa, emphasizes that a typical septic inspection covers three critical elements: the septic Tank, distribution box, and leach field. A passing check implies that all these components function properly and are structurally sound.

• Locating the Septic System: Certified inspectors, whether private contractors, Health Department representatives, or wastewater professionals, initiate the process by finding the underground Tank. In cases where sketches are unavailable or unreliable, a small radio transmitter flushed down the toilet helps pinpoint the Tank’s location.

• Visual Inspection of the Drain Field: The inspector examines the drain field for signs of issues such as cesspools, sogginess, or standing water, indicating potential problems.

• Water Pressure and Leak Checks: Ensuring proper water pressure and distribution in the septic drain field is vital. Additionally, inspectors check for leaks, requiring the Tank to be pumped for a thorough examination.

• Measuring Solids Levels: The level of solids in the Tank, including scum and sludge layers, is calculated using a sludge judge—a long, hollow pole. This step provides insights into the Tank’s maintenance history.

• Baffles and Distribution Box Inspection: Baffles, preventing scum and grime buildup in pipes, are checked for proper functioning. The distribution box, ensuring even wastewater distribution to drain field lines, undergoes scrutiny for damage, structural integrity, and signs of uneven distribution.

Common Septic Inspection Findings and Repair Costs

A professional septic system inspection typically costs between $100-$250, with additional fees for uncovering the Tank. Understanding common issues discovered during inspections is crucial for estimating potential repair costs.

• Cracked Tank: Constructed from materials like concrete, steel, fiberglass, or polyethylene, septic tanks can develop cracks. Repair costs average around $2,000, while replacement can range from $5,000 to $50,000.

• Damaged Walls: Shifting ground, exposure to elements, or invasive tree roots can damage tank walls, leading to leaks. Repair costs range from $500 to $4,000.

• Faulty Distribution Box: This critical component, controlling wastewater distribution, may incur costs between $500 and $1,500 for replacement.

• Pump Failure: The septic tank pump, crucial for effluent flow to the drain field, may need replacement every few years, costing $500 to $1,500.

• Invasive Roots: Trees or shrubs planted too closely can damage pipes, necessitating removal of roots for $1,000 to $5,000. Extensive damage may require pipe replacement.

• System Size Mismatch: If the septic system is too small for the home, overloading occurs, leading to water on the ground surface. Installing a larger tank can cost between $1,200 and $1,600.

• Baffles Clogged: Baffles prevent pipe clogs and may need repair, costing $150 to $600.

• Low Bacteria Level: Aerobic Treatment Units may experience efficiency issues due to low bacteria levels. Adding bacteria costs $350 to $650.

• Swampy Drain/Leach Field: Repairs or rejuvenation for a malfunctioning drain field range from $1,500 to $5,000, with complete replacement costing $2,000 to $10,000.

• Tank Overflows: Pumping a full tank costs $250 to $895, with potential additional costs for issues like invasive tree roots.

• Septic Tank Doesn’t Drain: Clearing clogs can cost $250 to $10,000, depending on severity. Issues like baffle replacement may cost around $150, while lateral line replacement costs $2,000.

• Sinking Ground: Repairing sloping ground may cost $1,000 to $10,000, depending on the cause, such as corroded pipes or a cracked tank.

• Leach Field Leakage: Repairs for a leaking leach field range from $1,500 to $20,000.

When and Who Pays for Septic Inspections

The National Association of Certified Home Inspectors recommends an annual septic system inspection, with additional checks when listing a property. Some mortgage companies and state or local regulations may mandate inspections. In Iowa, for example, septic inspections are required for property deed transfers.

Responsibilities and Considerations: Buyer, Seller, and As-Is Sales

Understanding who is responsible for inspection costs and potential repairs is essential. In Iowa, it’s common for the seller to pay for the inspection, although it’s negotiable. Whether repairs are the seller’s responsibility depends on negotiation and regulatory requirements.

When issues are uncovered, sellers must decide whether to cover repair or replacement costs, find a cash buyer for an as-is sale, set up an escrow holdback, or reduce the sale price to account for needed work. As-is sales often require approval from regulatory bodies and a limited timeframe may be imposed for issue resolution.

Maintaining Septic Health: A Long-Term Perspective

Properly maintained septic systems can last 25 years or more without replacement. Regular pumping every 3 to 5 years, based on household size, tank capacity, and environmental factors, ensures system efficiency. Steve Phelps of Affordable Septic and Repair emphasizes that addressing issues promptly is crucial, as septic systems won’t fix themselves.

In conclusion, being proactive about septic inspections is a regulatory requirement and a safeguard for your property’s well-being. Knowing the intricacies of your septic system, understanding the potential issues, and addressing them promptly contribute to the long-term health and functionality of this essential component of rural living.
