Proper maintenance of your septic tank is crucial for its longevity. Monthly, check for odors, wet spots, and balance water usage to avoid overloading. Quarterly, add bacterial additives to maintain the bacterial balance. Annually, schedule a professional inspection to check the tank, baffles, and drain field, and measure sludge levels. Every 3-5 years, pump your septic tank to remove accumulated sludge and scum. Address any repairs promptly and maintain the drain field to ensure proper drainage. Conserve water, dispose of waste properly, and protect the drain field from heavy vehicles and deep-rooted plants. If you notice foul odors, slow drains, gurgling sounds, or wet spots over the drain field, it's time to call for service.
