If your septic alarm keeps going off and won’t stop, a clogged drainfield could be the cause. In this video, you are seeing black sludge and biomat buildup erupting from a pressure distribution drainfield lateral — a clear sign of a clogged drainfield. This blockage was straining the effluent pump and triggering constant septic alarms.
We restored the drainfield using hot water hydrojetting, clearing the biomat buildup from the lateral lines and relieving pressure on the system.
This is a common fix when:
✅ Septic alarm won’t stop going off
✅ Effluent pump running constantly and effluent isn’t leaving the tank
✅ Higher than usual electric bill
✅ High level accumulation of solids in the pump tank
If your alarm keeps sounding, don’t ignore it — it usually means the system is under stress somewhere downstream of the tank.
