The Environment One pump is capable of accepting and pumping a wide range of materials. Regulatory agencies advise that the following item(s) should not be introduced into any sewer, either directly or through a kitchen waste disposal unit:
Seafood or eggshells
Diapers, socks, rags or cloth
Plastic objects, (toys, utensils, etc.)
Sanitary napkins or tampons
Fish tank stone
In addition, you must never introduce into your sewer:
In order to provide you with suitable wastewater disposal, your home is served by a low-pressure sewer system. The basic unit in this system is an Environment One grinder pump. The tank collects all solid materials and effluent from the house. The solid materials are then ground to a small size suitable for pumping as a slurry with the effluent water. The grinder pump generates sufficient pressure to pump this slurry from your home to the wastewater treatment receiving line and/or disposal plant.
