A grinder or effluent pump is capable of accepting and pumping a wide range of materials found in domestic sewage.  Regulatory agencies advise that the following items should not be introduced into any sewer system either directly or through a kitchen waste disposal unit:

• Glass 
• Metal
• Plastic (toys, utensils, etc.)
• Sanitary napkins or tampons
• Seafood shells
• Diapers, rags, clothing, etc.

In addition, you must NEVER introduce into any sewer system:

• Explosives
• Flammable materials, such as  gasoline or paint thinner
• Oil or grease
• Strong chemicals (lye, household cleaners, etc.)

Power Failure: Your pump cannot dispose of wastewater without electrical power.  If electric power service is interrupted, keep water usage to a bare minimum, as it is illegal to have wastewater run on the ground.  The maximum penalty is $500.00 per day and/or jail time.

Water Infiltration: Make sure no outside source of water can get into the tank (leaking toilets or sinks, unsealed tanks, etc), because your pump has to work harder to dispose of this excess water.

Cleaning: Wash the float, tank and lines down with a hose at least monthly, as grease, detergent, etc. will build up on these items.

Parts Replacement: Replace grinder blades annually.
