A septic tank is the most popular and cheapest solution used by people who do not have a sewage connection. The only operating cost is the need to regularly empty the tank. If the conditions are right, you can do it yourself, but you need to have the right pump. Sometimes it must be equipped with a shredder. Find out what to consider when choosing a pump with a grinder.
What is the grinder in a septic tank pump used for?
Septic tank pump is a device used to discharge sewage from a septic tank. It is a type of dirty water pump, but with a special purpose. It is immersed deep into the septic tank, where it pumps both treated and untreated sewage to the appropriate height. The sewage contained in the septic tank is characterized by a large amount of solid pollutants, and the ability to deal with them distinguishes a septic tank pump from a dirty water pump. It not only has a reinforced structure, but is also equipped with a special shredder. It is a type of knife that, when sewage flows through the pump, breaks solid particles into smaller elements, making them pass through the device much easier. The shredder therefore makes pumping heavily contaminated sewage not only easier, but also faster. When deciding to buy a pump, it is necessary to check whether it is adapted to pumping water from a septic tank, because otherwise it will not cope with this task.
The most important features of the grinder pump
In order for a pump with a grinder to properly fulfill its function, you must first of all pay attention to its quality. It is not enough to just find information on the box that it is equipped with it. Cheap devices of unknown origin may have appropriate cutting knives, but this does not mean that they will be up to the task. Their most important feature is the use of durable and proven materials, which can certainly be found in devices from renowned manufacturers.
The choice of a grinder is also important, as there are pumps equipped with a grinder on the market:
- knife - adapted for grinding small impurities with a moderate degree of hardness,
- hammer - designed to deal with hard and compact deposits,
- rotor - intended for thicker waste, its design increases the efficiency of the pump, which is why it can empty the tank very quickly,
- disk - intended for very hard dirt, used in professional septic tank pumps.
The operation of the pump with the grinder is effective and it perfectly copes with sewage containing large amounts of solids. However, it is important to choose pumps with a good quality grinder, as this will guarantee their long-term, failure-free operation.
