Your Septic Tank User Guide
Introduction
Your septic system is a vital component of your home, responsible for treating and dispersing wastewater safely. Proper maintenance is essential to prevent costly repairs, environmental contamination, and health hazards.
This handy guide provides detailed instructions on how to care for your septic system and ensure its longevity.
Be Water Wise
Excessive water use overloads your septic system and can push solids into the drain field before they're properly treated.
- Repair leaky faucets and toilets promptly.
- Use water-saving appliances (e.g., low-flow showerheads, high-efficiency washing machines).
- Spread out water-intensive activities like laundry loads throughout the week.
- Avoid running half-empty dishwashers.
Only Flush the "Three Ps"
These are: Pee, Poo, and Paper. Toilet paper that is. Everything else can cause problems.
You should never flush:
- Feminine hygiene products (tampons, pads, wipes)
- Condoms
- Dental floss
- Diapers (cloth or disposable)
- Paper towels
- Cat litter
- Cigarette butts
- Coffee grounds
- Food waste
Think at the Sink
What goes down your drains in the kitchen and bathroom also affects your septic tank.
- Avoid pouring grease, fats, and oils down the drain. Wipe greasy dishes with paper towels before washing and dispose of grease in a sealed container in the trash.
- Don't pour harsh chemicals down the drain. This includes drain cleaners, solvents, paints, pesticides, and even excessive amounts of antibacterial soaps and cleaners, as they can harm the beneficial bacteria in your tank that break down waste. Opt for septic-safe and environmentally friendly cleaning products.
- Use sink strainers to catch food scraps.
Boost Your Bacteria
Bacteria augmentation kits like those offered by Sea-Chem are the most effective way of nurturing and replenishing the friendly bacteria which make you system tick.
