A septic system rarely fails without warning. Recognizing these signs early can save thousands of dollars in repair costs:
Over time, solids settle at the bottom of the tank (sludge) and oils/grease float to the top (scum). If the tank is not pumped every 3 to 5 years, the sludge layer rises high enough to block the outlet pipe or the inlet baffle, allowing solids to flow into the drain field, which causes catastrophic failure. clogged septic tank
