Drainage & Sump Systems under a real house, step by step
Water gets into a crawl from outside far more often than from below. Gutters discharging at the wall and grade that falls toward the house are the usual causes, and fixing those is cheaper than anything you can do under the floor.
A sump with no battery backup fails exactly when it is needed, because the storms that flood crawl spaces are the storms that take the power out.

FAQ
Under the house: drainage & sump systems questions
Why is there standing water in my crawl space?
Because water from outside is getting in and has nowhere to go — from gutters dumping at the foundation, from ground that slopes toward the house, or from a water table that rises in wet weather. Standing water rots framing, feeds mold and draws termites. It is dealt with by getting the water away outside and, where that is not enough, by an interior drain and a sump pump.
Do I need a sump pump in my crawl space?
If water collects there after rain, yes, and with a battery backup, because the storms that fill a crawl space are the storms that take the power out. The pump sits in a basin at the low point with an interior drain feeding it, and it discharges well away from the house. It is installed before the space is sealed, not after.
