A grinder pump is a conveyance device. Waste from water-using household appliances (, etc.) flows through the home’s pipes into the grinder pump’s holding tank.

Once the inside the tank reaches a specific level, the pump will turn on, grind the waste into a fine slurry, and pump it to the central. Grinder pumps can be installed in the basement or in the yard. If installed in the yard, the holding tank must be buried deep enough that the pump and sewage pipes are below the.

A grinder pump is different from a or effluent pump. There are two types of grinder pumps, semi-positive displacement (SPD) and. Grinder pump station with HDPE tank being installed The grinder pump “station” consists of the pump, a tank, and an alarm panel. A pump for household use is usually 1, 1.5 or 2.

A cutting mechanism macerates waste and grinds items that are not normally found in sewage, but may get flushed down the toilet, the pump has a level sensor either built into the pump, called “sensing bells,” or attached externally to the pump, called “floats.” (The level sensing devices vary among grinder pump manufacturers.) If the pump malfunctions and the waste level in the holding tank rises above a certain level, the alarm panel should alert the homeowner that the pump is experiencing problems. The alarm panel should have both a buzzer and an indicator light. The holding tank, likely constructed of, (HDPE) or fiberglass-reinforced (FRP), has an inlet opening and a discharge opening. The pipes from the home are connected to the inlet; the pipe that leads to the sewer main is connected to the discharge.

Often, more than one home or restroom (in a park, for example) can be connected to one grinder pump station; in this case, more than one inlet can be installed. It is a good idea to consult the manufacturer or factory representative before purchasing a grinder pump station to ensure that more than one inlet hole can be drilled. The tank has a lid made from heavy-duty plastic or metal that is bolted and/or padlocked shut to prevent entry by unauthorized persons. Maintenance Grinder pumps should not require preventive maintenance.

However, grinder pumps that use floats to sense the level in the holding tank are prone to grease buildup that may turn the pump on unnecessarily, or not turn on the pump at all, causing the tank to fill up and sewage to possibly back up into the home or yard. To prevent this, grinder pumps that use floats are often hosed down to remove the grease from the floats. Homeowners are not usually limited by what they can or can not pour down their drains because their home has a grinder pump.

Not only do people clog their household, they are causing problems with household grinder pumps, and, some wipe companies say 'flush one at a time,' some say 'not for pump systems,' some say 'safe for sewers.' As recommended by, wipes should be put into a garbage can instead of the toilet.

The National Association of Clean Water Agencies has compiled a list of articles and municipal documents regarding wipes. In large sewage pump stations, clogging problems are often avoided by installing a in the tank.
