A Comprehensive Guide to Septic Inspections for Homebuyers in Rural Nevada and Placer County

Introduction

Purchasing a rural property in Nevada and Placer County often means dealing with a septic system rather than a municipal sewer connection. At Sierra Foothills Home Guide, we understand the importance of ensuring these systems are in good working order. Here’s an in-depth look at what a septic inspection involves, why it’s necessary, and what you can expect from the inspection report.

Why Septic Inspections are Essential

Septic systems are critical for managing wastewater in rural areas, but they require regular maintenance and inspections to function properly. A thorough inspection helps identify potential problems early, ensuring the system operates efficiently and prevents costly repairs in the future.

Step One: Locating the Septic System

The first step in a septic inspection is locating the system. Some homes will have easily accessible lids, while others may require locating and digging to uncover the septic tank.

Methods for Locating the System

• Probing: Inspectors use a three-foot metal probe to find the exact location of the septic tank.
• Radio Transmitter: If the location is unknown, a radio transmitter attached to a fiberglass push rod helps determine the tank’s depth and direction, saving time and effort.

The Inspection Process

Once the tank is located and uncovered, a comprehensive inspection is performed, which may involve pumping the tank first to allow a thorough assessment.

Why Pumping May Be Necessary

Pumping the tank is often required if it hasn’t been done within the last year. This step ensures that 90% of the tank is accessible for inspection, allowing a clear view of the interior condition and preventing any hidden issues.

Detailed Examination of the Septic System

1. Septic Tank Capacity

Understanding the septic tank’s capacity is crucial for assessing whether it can handle the household size. Septic systems are typically designed based on the number of bedrooms, estimating two people per bedroom at 150 gallons per day per person. Common tank sizes range from 1,000 to 1,500 gallons for an average three-bedroom home. Proper capacity ensures the system can manage the wastewater volume without overloading.

2. Condition and Construction Material of the Tank and Lids

The durability and lifespan of a septic tank largely depend on its construction materials. Here’s what you might find:

• Concrete Tanks: Durable and long-lasting, but can be susceptible to acid damage over time, especially in certain soil conditions.
• Polyethylene (Plastic) Tanks: Lightweight and resistant to corrosion but can be vulnerable to damage if not installed correctly.
• Metal Tanks: Common in older systems, but prone to rust and corrosion, leading to leaks and failures.

Inspectors check for cracks, structural integrity, and any signs of wear that might compromise the tank’s performance.

Inspection of System Components

Inlet and Outlet ‘T’ Condition

The inlet and outlet ‘T’ components direct the flow of wastewater into and out of the septic tank. Inspectors check these parts for:

• Breakage: Damaged ‘T’s can disrupt the flow of wastewater, leading to backups.
• Stoppage: Blockages can cause overflow and system failure.
• Root Infiltration: Roots can penetrate and clog the ‘T’s, requiring removal and repair.

Baffle and Baffle Vent Space

The baffle prevents solids from entering the leach field, protecting it from clogging. There are different types of baffles:

• Concrete Baffles: Durable but can deteriorate over time.
• Plastic Baffles: Resistant to corrosion but must be installed correctly to function properly.
• Filter Baffles: Include a filter to trap solids, requiring regular maintenance to avoid blockages.

Inspectors ensure the baffle is intact and functioning to prevent solids from entering the leach field.

Checking for Abnormalities

Inspectors look for signs of system failure, including:

• Overflow: Indicates a potential blockage or insufficient capacity.
• Missing Structural Items: Missing or damaged components can compromise the system.
• Wet Spots: Surface water around the septic area suggests leakage or overflow.

Water Level Check

Inspecting the water level helps detect leach field problems. A higher water level than the outlet pipe indicates possible leakage or a failing leach field.

What is a Leach Line and Why is it Important?

A leach line, also known as a drain field or leach field, is a critical component of a septic system. It is a network of perforated pipes buried in a trench filled with gravel or other porous material. The primary function of a leach line is to disperse and filter the effluent (wastewater) that flows out of the septic tank into the surrounding soil.

Importance of a Leach Line

System Longevity: Well-maintained leach lines can significantly extend the life of a septic system by preventing the accumulation of solids and preventing clogging of the soil pores.

Effluent Disposal: Leach lines ensure that the wastewater is effectively dispersed into the soil, where it undergoes natural filtration and decomposition by soil microbes. This process helps remove harmful bacteria, viruses, and nutrients from the effluent.

Preventing System Overload: By distributing the effluent over a large area, leach lines prevent the soil from becoming saturated. This helps maintain the efficiency of the septic system and prevents backups or overflow.

Protecting the Environment: Properly functioning leach lines help prevent contamination of groundwater and nearby water bodies by ensuring that the wastewater is treated before it reaches these sources.

System Repairs and Recommendations

During your inspection period, a detailed septic report will be provided to the seller, highlighting the condition of the system and any necessary repairs. This report is essential for negotiating repairs or credits with the seller to ensure the septic system is in optimal condition upon purchase.

Necessary Repairs

Any required repairs identified during the inspection will be essential to bring the system back to optimal condition. This includes:

• Fixing Cracks: Repairing any cracks in the tank or pipes to prevent leaks and system failures.
• Replacing Damaged Components: Swapping out any broken or worn-out parts, such as inlet and outlet ‘T’s, baffles, and lids.
• Ensuring Functionality: Confirming all parts of the system are working correctly to maintain the overall efficiency and safety of the septic system.

Negotiating these repairs or credits with the seller ensures that the septic system will be functional and reliable, protecting your investment and the environment. Regular inspections and maintenance of the leach line and other septic system components are crucial for long-term performance and peace of mind.

A septic inspection is a crucial step in the home-buying process for properties with septic systems in rural Nevada and Placer County. It ensures that the system is in good condition, identifies potential issues early, and prevents costly repairs in the future. Knowing what to expect during a septic inspection helps homebuyers make informed decisions and maintain a healthy, functional septic system.
