Troubleshooting a Sticking Float in a Septic Tank
- 1). Lift the maintenance access hole cover from the tank and set it aside.
- 2). Observe the location of the electrical wires and debris in the tank. Wires leading from the float switches attached to the pump's standpipe should be securely attached and in no way inhibit the free movement of the floats.
- 3). Lower the pump hook until it is below the float switch. Raise and lower the float switch, checking to see if an electrical wire or debris obstructs its movement.
- 4). Raise the float to its fully open position, and if the pump does not pump or the alarm does not sound, give the float a bump. If the alarm then trips or the pump then starts, replace the float.
- 5). Replace the septic tank maintenance access cover.
