What Is A Sewage Grinder Pump and Do You Need One?

A sewage grinder pump is an important device used in many homes to aid in waste management. Sewage pump grinders help with the disposal of everything sent to the septic tank through sinks, bathtubs, showers, and toilets. The wastewater from all the appliances makes its way through the pipes and connects into the grinder pump storage system. Once a certain level of waste is in the grinder it will activate and grind the waste into fine slurry and pump it into the main septic system.

On the market today are the most commonly used sewage grinder pumps: the Centrifugal Grinder Pump and the Semi-Positive Displacement (SPD). What makes up a grinder pump system is the tank, the grinder/pump and the alarm panel. For most households, a pump having 1 to 2 horsepower is plenty. The grinder pump has sensors built in and attached on the exterior. The sensors detect how full the grinder pump tank is and if there are problems with the system.

Homeowners they do not have too worry much about their sewage grinder pump malfunctioning allowing the waste to overflow because the sensors will detect it before it is a problem. The homeowner will then be alerted via the alarm panel and they can then fix the problem or call a septic system contractor to fix it.

Depending on the manufacturer, the materials used in manufacturing grinder holding tanks can vary but the most common types are constructed from high-density polyethylene (HDPE), fiberglass or fiberglass reinforced polyester (FRP). All makes of sewage grinder pumps have an opening that serves as an inlet for the waste and a discharge outlet leading to the main septic tank. If you are installing this system into an existing house there is very good chance that you will have to modify the plumbing in order to incorporate a sewage grinder pump. There are also grinders that are large enough to be able to service multiple homes which are all connected to one grinder pump station and one septic tank system.

Advantages of a Sewage Grinder Pump

By grinding up the waste the surface area is increased which means that the bacteria and enzymes in the septic tank will be able to decompose the waste more quickly and efficiently. This may lead to fewer septic tank pumping calls. The alarm system for the alarm is a big advantage because you will be alerted to any problems so you do not have to constantly check the system. If you have a food-disposal unit in your kitchen sink (not recommended for normal septic tank setups) then the food will go through an additional grinding cycle making it easier to process.

As a final note, although sewage grinder pumps help a lot you still cannot send harmful chemicals down your drains; for example, sanitary products, kitty litter, oils, paints, etc.
