Ideally a sump pump should be installed in the lowest point of your crawlspace or basement. This will allow the water to naturally grade down to this point so it will not pool. When a large amount of water is present or the area is generally level, we do then recommend a drainage system is installed to assist directing the water to the sump pump. From here the sump pump will divert and push all of the water safely out and away from the home's foundation.
