A grinder pump, also known as a sump pump, resembles a larger household garbage disposal unit. It takes the waste water of the house, from items such as toilets, showers and dishwashers, and then converts it into a slurry. This slurry is then moved into the public sewer system. The grinder pump is surrounded by a tank which stores waste until there is enough to be ground into the slurry. Some homes require a grinder pump, as the gravity flow from a household waste pipe into the sewer may not be enough. In places where the home is in a valley, or on low-lying ground, a grinder pump is necessary to push the waste up and into the drain. If you are looking for a new grinder pump, there are several factors which should influence your decision on which pump to buy.
The principle of the grinder pump is to convert sewage into a movable slurry, but there are several designs of pump. One of the latest innovations includes a chopping, or sawing machine by the tank's inlet pipe. This cuts down pieces of sewage which may have jammed the grinder pump previously. This limits one of the biggest problems which the pumps have, that of being easily blocked. The designs of the pump can include noise level reduction, for example. Another form of grinder pump design uses floating weights which trigger the pump when it reaches a certain level. Consider the design when making a purchase.
Another important aspect is that of the size of the grinder pump. They come in a variety of sizes, some of which may be more suitable than others. A small home or apartment, with 1 or 2 people living there, may need a smaller pump than a household with 6 or 7. Size relates to the cost of the whole pump, and may also affect the choice of designs you have available to you. You should consider the size requirements of the tank and pump before purchasing.
The cost of a grinder pump is also a consideration. In houses who are regularly having to call out plumbers to remove sewage from pipes, a pump of this nature can help to cut those costs, although you will still need to consider calling out a professional for the installation and maintenance of the pump. There is very little on the pump that can be done by the householder, so once it is installed you will need annual servicing, and call outs for any other times. These costs, plus the costs of the original installation, should be considered when choosing the type of grinder pump you want.
Grinder pumps run on electricity, and they are perhaps not very fuel efficient. If you are trying to live a greener life, then one option is to convert the waste without a grinder pump, although human waste products are not suitable for the garden. There are some grinder pumps that attempt to deliver efficiency, doing so by limiting the time that the grinder operates, and the time between uses. This can save money as well as being greener.
