When you have a septic system, it's essential to consider its capacity when doing laundry. To maintain its health and functionality, limit laundry loads to once or twice a week. Spreading out the loads helps prevent overloading the system with excess water and detergent. It's also advisable to use septic-safe laundry detergents and avoid using bleach or harsh chemicals that can disrupt the septic tank's balance. Regular maintenance and pumping are crucial for the longevity of your septic system.
