Frequently Asked Questions

Septic System FAQ

1What is a septic system, and how does it work?

A septic system is an onsite wastewater treatment setup for properties not connected to public sewer. All wastewater from the home enters a septic tank, where solids settle to the bottom and lighter materials float. The partially treated water then flows into a soil-based or engineered system — such as a sand mound, at-grade bed, or advanced treatment unit — where the final purification takes place before re-entering the ground. When installed and maintained correctly, a septic system is safe, reliable, and long-lasting.

2How often should a septic tank be pumped?

Most households need pumping every 3–5 years.

Pump frequency depends on:

  • Home occupancy
  • Tank size
  • Water usage
  • Whether garbage disposals or high-volume appliances are used

Routine pumping prevents solids from reaching and damaging the treatment area.

3How often should my septic system be inspected?

You should schedule an inspection:

  • Every 1–2 years for residential homes
  • Annually for commercial properties
  • Whenever buying or selling a home
  • Before renovations or adding bedrooms

Inspections catch problems early and protect both property value and the system’s lifespan.

4What are the warning signs of a septic system problem?

Big red flags include:

  • Slow drains or gurgling pipes
  • Sewage backing up
  • Wet or spongy areas over the system
  • Strong odors outdoors
  • Pump tank alarms or high water levels
  • Standing water around the drainfield or mound

These indicate the system needs immediate attention.

5What should NEVER go into a septic system?

Avoid flushing or draining:

  • Wipes (any kind)
  • Grease, fats, oils
  • Feminine hygiene products
  • Paper towels or tissues
  • Bleach, harsh chemicals, or antibacterial cleaners
  • Paint, solvents, or automotive fluids
  • Cat litter

These items clog pipes, kill essential bacteria, and cause system failure.

6Is a garbage disposal safe for a septic system?

A garbage disposal adds a large amount of solids to the tank. While it can work, it increases pumping frequency and strains the system. If you have one, use it sparingly or avoid it altogether.

7How do I protect my drainfield or sand mound?

Keep the area:

  • Clear of vehicles, heavy equipment, and structures
  • Free of trees or deep-rooted plants
  • Dry — no roof drains or sump pumps discharging onto it
  • Aerated — avoid compacting the soil with heavy objects

A healthy drainfield is open, dry, and undisturbed.

8How long does a septic system last?

A well-installed and well-maintained septic system generally lasts 20–40 years. Soil conditions, proper pumping, water usage, and system design all influence lifespan.

9What should I do if my septic alarm goes off?

If your alarm activates:

  1. Stop using water immediately.
  2. Check for tripped breakers.
  3. Call us right away.

An alarm usually means the pump isn’t working or water levels are too high. Both require quick action.

10What should I know when buying a home with a septic system?

Before closing, you should:

  • Schedule a certified septic inspection
  • Review pumping and maintenance records
  • Confirm system type and age
  • Learn where each component is located
  • Ensure the system matches the home’s bedroom count

A real estate septic inspection helps protect buyers from future issues.

11Are septic additives helpful?

Most additives are unnecessary and can actually harm the system. A healthy septic system relies on natural bacteria, proper water usage, routine pumping, and correct installation, not chemicals or “boosters.”

12What daily habits help keep a septic system healthy?

You can extend system life by:

  • Fixing leaks quickly
  • Spreading out laundry loads
  • Using septic-safe soaps and paper products
  • Conserving water
  • Keeping grease out of drains
  • Pumping and inspecting on schedule

Good habits create decades of trouble-free performance.

13Can landscaping affect my septic system?

Yes. Keep trees and shrubs away from the tank and drainfield to prevent root intrusion. Use grass or shallow-rooted plants over the drainfield area. Avoid heavy mulch, rock beds, and dense gardens.
