Keeping a septic system healthy isn't complicated, but it does require a few habits. Most of the work is about what you don't flush and don't do - the system handles normal household use well when you give it the chance.
Ongoing (Every Day)
- Flush only human waste and toilet paper. Nothing else belongs in a septic system - not "flushable" wipes, not feminine hygiene products, not paper towels, not medication.
- Don't pour grease or cooking oil down the drain. Grease accumulates in the scum layer and dramatically shortens the interval between pump jobs. Let it solidify and put it in the trash.
- Use septic-safe cleaning products. Occasional use of bleach-based cleaners is fine; heavy regular use can kill the beneficial bacteria in your tank. Look for septic-safe labels on household cleaners.
Weekly
- Spread laundry loads throughout the week. Doing multiple loads in one day sends a large surge of water into the tank, reducing its ability to separate solids. One or two loads per day is better than six in one morning.
- Check for leaks. A constantly running toilet or dripping faucet can add hundreds of gallons of unnecessary water to your septic system per day, overwhelming it over time.
Monthly
- Look at the drain field area. Walk the area over your drain field and note anything unusual - very green or wet patches of grass, odors, or standing water after dry weather. Early observation prevents serious problems.
- Check that no surface water drains toward the system. Downspouts, sump pump discharge, and surface runoff should be diverted away from the drain field, not toward it.
Annually
- Have the system inspected. An annual inspection by a licensed professional can catch developing issues (failing baffles, tree root intrusion, settling) before they become major repairs. This is separate from pumping.
- Check the tank riser lids. Make sure they're secure and haven't cracked or shifted. An unsecured lid is a safety hazard, especially in households with children.
Every 3-5 Years
- Pump the tank. The most important maintenance item. Schedule based on your household size and tank size - see our pumping frequency guide.
- Ask for an effluent filter check. Many modern tanks have effluent filters at the outlet. These need cleaning or replacement periodically.
Things to Never Do
- Don't park vehicles or equipment on the drain field - it compacts the soil
- Don't plant trees or large shrubs within 30 feet of the drain field - roots seek water
- Don't use a garbage disposal if you can avoid it - it significantly increases solids load
- Don't add septic tank additives or enzymes - the EPA has found no benefit and some can cause harm
- Don't divert roof runoff or HVAC condensate drainage toward the drain field
