Septic System Do's and Don'ts

The Essential Guide to Septic System Do's and Don'ts

Owning a home with a septic system comes with specific responsibilities that differ from homes connected to municipal sewer lines. Your septic system is a living ecosystem that requires proper care to function effectively. Understanding what to do — and what to avoid — can mean the difference between a system that lasts 30+ years and one that fails prematurely. This comprehensive guide covers the essential do's and don'ts every septic system owner should know.

The Do's: Best Practices for Septic System Care

DO Pump Your Tank Regularly

This is the single most important maintenance task for your septic system:

• Schedule pumping every 3-5 years depending on household size and usage
• Keep records of every pumping date and the technician's findings
• Have the tank inspected during each pumping
• Do not wait for signs of problems — prevention is always cheaper than repair
• Ask your pumping service to check baffles, measure sludge levels, and note any concerns

DO Conserve Water

Reducing water usage extends the time between pumpings and reduces strain on your drain field:

• Install high-efficiency toilets that use 1.6 gallons or less per flush
• Use water-saving showerheads and faucet aerators
• Run full loads in the dishwasher and washing machine
• Fix leaking faucets and running toilets promptly — a leaky toilet can waste 200 gallons per day
• Spread laundry over the week rather than doing multiple loads in one day
• Consider the water usage of any new appliances you purchase

DO Watch What Goes Down the Drain

Your septic system is designed to process household wastewater, not everything under the kitchen sink:

• Use septic-safe toilet paper that breaks down easily
• Scrape plates into the trash before washing
• Use minimal amounts of household cleaners
• Choose biodegradable, septic-safe cleaning products
• Collect cooking grease in a container and dispose of it in the trash

DO Protect Your Drain Field

The drain field is the most expensive component to repair or replace:

• Keep trees and large shrubs at least 30 feet from the drain field
• Plant only grass over the drain field area
• Direct roof drains, sump pumps, and other drainage away from the field
• Keep heavy vehicles and equipment off the drain field
• Do not pave, build, or install anything over the drain field
• Ensure gutters and downspouts do not drain toward the field

DO Know Your System

Understanding your septic system helps you maintain it properly:

• Know the location of your tank, distribution box, and drain field
• Keep a map or diagram of the system for reference
• Understand what type of system you have (conventional, mound, aerobic, etc.)
• Keep all maintenance records organized and accessible
• Know the age of your system and its expected lifespan
• Familiarize yourself with your local regulations regarding septic systems

DO Schedule Regular Inspections

Professional inspections catch problems before they become emergencies:

• Have your system inspected every 1-3 years
• Include inspection with each pumping service
• Get an inspection before buying or selling a home
• Have the system checked if you notice any changes in performance
• Keep inspection reports for your records

DO Use Your System Regularly

Consistent, moderate use is better than irregular heavy use:

• Regular water flow keeps bacteria active and pipes clear
• If the home will be vacant for extended periods, have someone run water periodically
• Gradual increases in usage are better than sudden surges
• Balance usage throughout the day rather than all at once

The Don'ts: What to Avoid

DON'T Flush Non-Biodegradable Items

Your toilet and drains are not trash cans. Never flush or drain:

• "Flushable" wipes — Despite marketing claims, they do not break down
• Feminine hygiene products — Tampons, pads, and applicators
• Condoms — They do not decompose in the tank
• Diapers — Even small amounts can cause blockages
• Cotton swabs and dental floss — They tangle and create clogs
• Cat litter — Even "flushable" varieties harm septic systems
• Paper towels and tissues — They are not designed to break down like toilet paper
• Cigarette butts — They contain chemicals that kill beneficial bacteria
• Medications — They can kill the bacteria your system needs and contaminate groundwater

DON'T Pour Chemicals Down the Drain

Harsh chemicals destroy the beneficial bacteria that make your septic system work:

• Bleach in large quantities — Small amounts are okay, but avoid pouring cups of bleach
• Drain cleaners — Chemical drain cleaners are especially harmful
• Paint and paint thinners — These are hazardous waste
• Pesticides and herbicides — Toxic to bacteria and groundwater
• Motor oil and gasoline — Hazardous and destructive to the system
• Antibacterial soaps in excessive amounts — They can reduce beneficial bacteria
• Photographic chemicals — Contain silver and other harmful compounds

DON'T Use a Garbage Disposal Excessively

Garbage disposals dramatically increase the solid waste entering your tank:

• They can increase sludge buildup by 50% or more
• If you must use one, use it sparingly
• Never grind fibrous materials (celery, corn husks) or starchy foods (pasta, rice)
• Consider composting food waste instead
• If you use a disposal regularly, plan to pump your tank more frequently

DON'T Ignore Warning Signs

Early detection saves money and prevents environmental damage:

• Slow drains — May indicate a full tank or system problem
• Gurgling sounds — Suggest air being trapped or drainage issues
• Sewage odors — Never normal, always investigate
• Wet spots near the tank or drain field — Indicate potential failure
• Sewage backup — An emergency requiring immediate professional help
• Lush grass over the drain field — May signal effluent surfacing

DON'T Use Septic Additives Without Professional Advice

The septic additive market is full of products that promise to eliminate the need for pumping or fix system problems. The reality is more nuanced:

• Most additives are unnecessary for a properly maintained system
• Some can actually harm your system by disrupting the natural bacterial balance
• Chemical additives can damage tank components and contaminate groundwater
• Biological additives are generally safe but rarely necessary
• No additive eliminates the need for regular pumping
• Consult a septic professional before using any additive

DON'T Attempt DIY Repairs on Major Components

Septic systems involve hazardous materials and complex engineering:

• Septic gases can be lethal — never enter a tank
• Improper repairs can make problems worse and more expensive
• Code violations from amateur work can result in fines
• Environmental contamination from improper work carries serious consequences
• Always hire licensed professionals for repairs and installations

DON'T Overload Your System

Sudden surges of water can overwhelm your system:

• Do not run multiple water-intensive appliances simultaneously
• Avoid hosting events that drastically increase water usage without planning
• Do not allow roof drainage or stormwater to enter the septic system
• Space out water usage throughout the day
• Fix running toilets and leaking faucets immediately
