The frequency with which you need to exhaust your septic tank depends on on how fast the tank is filling up. For a typical household, the frequency is two to three times in a year.
Exhasuter services are aimed at emptying the septic tank before an overflow occurs. This is however rare because people rely on visual observations before calling for exhauster services. It is therefore important to install a high level indicator in a septic tank. By use of a light bulb or an audio alarm, you will know the time to exhaust. This will avoid overflows. Call us soon as you need exhauster services.
