When you call a septic company, the technician will inspect for leaks and examine the scum and sludge layers in your septic tank.
Keep maintenance records on work performed on your septic system.
Your septic tank includes a T-shaped outlet which prevents sludge and scum from leaving the tank and traveling to the drainfield area. If the bottom of the scum layer is within six inches of the bottom of the outlet, or if the top of the sludge layer is within 12 inches of the outlet, your tank needs to be pumped.
To keep track of when to pump out your tank, write down the sludge and scum levels found by the septic professional.
The service provider should note repairs completed and the tank condition in your system’s service report. If other repairs are recommended, hire a repair person soon.
