How to replace the drainage trough?
We would not expect to replace the 9mm trough during the life of the Ovivo Screw Compactor. The drainage trough is fabricated from 9mm thick mild steel. This design feature is very different from most other compactor types, which use 2-3mm thick stainless steel troughs. Unless the screw compactor is maintained correctly these troughs would show signs of extreme wear over a period of time and eventually fail. We would not expect this from the Ovivo Screw compactor.
