Sump Pumps for Basements and Crawlspaces
If unwanted water is making its way into your basement, then you may want to consider installing a sump pump.
A sump pump works to keep ground water from making its way into your home. The sump pit - located within the sump pump - is set to a particular level that will trigger the pump to remove water once a maximum has been reached.
Sump pumps are also useful for removing moisture if it has already made its way into a basement. The sump pump does not work to keep leakage from entering through the walls of a basement, but instead to reduce ground water that may cause or worsen an already existing problem.
It is possible to install a sump pump on your own; however, it does require a great deal of work and the use of heavy machinery, like a jackhammer. For this reason, you may want to consider the opinion of a professional who has the necessary equipment at his or her disposal.
