There are two basic types of sump pumps and it really is a matter of personal preference as far as which one you're going to use. The pedestal pump is one of the more common that is used and with this particular type of sump pump, the motor is above the water level which makes it easy to access. Submersible sump pumps, however, reside entirely below the surface of the water. This makes them less less conspicuous and at times, a better choice for use in your sump hole.
Whenever you are choosing submersible sump pumps for your home, it is important to make sure that you get one which is rated high enough to take care of the job. For example, if your home only rarely gets water in and your pump only runs once every couple of weeks at the most, you will not have to pump much water per minute. If, on the other hand, you find that your sump pump is running constantly, you should get one which pumps a lot of water per minute so that it can stay ahead of the demand.
Even though submersible sump pumps tend to be a little bit more expensive than the pedestal variety, you're going to get several benefits in return. First of all, they are much quieter whenever they are running which is very important if you tend to spend a lot of time in the area where it is installed. They are also going to last longer because they tend to be better sealed than the pedestal variety.
