Opt for biodegradable and septic-safe products whenever possible. Additionally, minimizing the use of water during heavy cleaning can help prevent overwhelming your system.

Additionally, be cautious about what goes down your drains; avoid flushing non-biodegradable items and limit the use of harsh chemicals.
