Septic Compass is a free service that connects homeowners with licensed local septic companies. We are not a contractor and do not perform septic work.
A typical system is sized for about 150 gallons per bedroom per day. Overloading it — long laundry marathons, leaks, or many guests — sends water to the drain field faster than it can absorb, risking backups. Spreading water use across the day keeps the system within its limit.
