What should I do if my unit is inactive for a year?

BIOROCK answer:

If your residence is vacant for a year, it will not be necessary to empty your septic tank; you will only need to remove the grease deposits.

When your unit is not in operation, the grease hardens and will lead to the clogging of the septic tank.
