Sump and Sewer Pumps
Sump and Sewer Pumps come in a range of styles.
The most common around the home is a Sump Pump with semi-vortex open impeller which means it can pump small soft solids whilst draining your sump.
For draining clear water, a standard drainage pump will do the job.
If you need to pump raw sewage, then you will need a Cutter or Grinder Pump which macerates the solid so they can be pumped with the liquids.
