A specially-equipped, licensed and bonded, septic tank service company should be hired to test the tank level, and as necessary, pump out and dispose of the sludge from the bottom of the septic tank. In addition, the septic tank company should check the alarm, baffles, compressor, motor, timer, and pump, as applicable to your system.

TIPS:

Since grease tends to clog septic tanks and slows down bacterial action, you should avoid pouring fats or oils down the drain.

Also do not put chemicals such as paint thinners, insecticides, or gasoline down the drains, as these will kill the important bacteria that break down waste products in the tank.

Further, to help extend the useful life of the septic system, insoluble solid material, such as plastic, rubber, rags, coffee grounds, and other foreign matter should never be flushed down the drain.
