If the blockage is very near the septic tank inlet, start digging. If there is no apparent blockage between the septic tank and the clean-out port, locate and remove the septic tank inlet inspection port lid. If the liquid level is below the level of the bottom of the inlet pipe, remove the blockage from the pipe or baffle. If the sewage comes out of the port or if the soil that was over the port is wet with sewage, or if the liquid level is above the top of the inlet pipe, the blockage is toward the drain field from the inlet port. Remove the inspection port lid over the outlet pipe of the septic tank. If sewage doesn't come out this port, the soil over the lid was not soggy with sewage, and the liquid is at the level of the bottom of the outlet pipe, pump out the tank and check for blockage in the connection between the first and second chambers of the tank. If sewage does come up out of both the inlet pipe inspection port and the outlet pipe inspection port, or if the liquid level is above the top of the septic tank outlet pipe, the blockage is on the drain field side of the septic tank. Pump out the septic tank and use the stiff wire to probe through the septic tank outlet toward the drain field. If a blockage is felt somewhere in the pipe going to the drain field distributions system and before the pipe connects to the distribution system, bring in the "sewer
