GRINDER STATIONS: Long Term/Winter Lay-up

Long term or winter lay-up does not adversely affect your grinder station.  However, there are a few routine steps that can take to prevent maintenance problems upon your return.  The following is a simple list of steps to take before seasonal or other long term absences:

  • Make sure nothing is blocking the airflow around the bottom of the cover.  
  • Before closing your home for an extended period of time (one month or longer), run clean water out from a faucet into your grinder station for approximately 30 minutes. This will thoroughly flush the line from your grinder station to the main line. Failure to flush the line could result in build-up in the line - which may result in the line being dug up and cleaned out at a considerable expense that may be turned over to the resident to pay.
  • DO NOT turn off the power to the grinder station at the panel.  If you normally turn off the main power to shut everything down, turn off all of the other individual circuits EXCEPT the grinder station.
  • Let someone know! If possible, let a trusted neighbor know you are leaving so that they listen and look for alarms. 
If you have any winterizing questions or concerns please call the city maintenance department at 320-251-5836.
The Sewer Department can be reached any time at (320)293-5111. If  your grinder station alarm is ringing please call immediately so the issue can be addressed right away.  If no answer, please leave a message stating the address of the grinder station and a return phone number.
