Like an automobile airbag, a sump pump is something you do not want to have to use. If you do need it though, it can really be a life saver. These pumps are available in either manual or automatic type, with battery operated backup sump pumps available as well.
If you do not have a sump existing in your basement floor, it is possible to create one yourself. You can use a saw with a special masonry blade, a powered chisel, of even a pick and shovel. In some way, a hole to collect water and contain the pump must be created. You will need to have a screen, to filter debris and avoid clogging the pump. You can have a float type switch, that will turn the pump on when the water level rises. If you seldom have water problems, you may get by with a manual pump, that you turn on yourself when you need it. Any type sump pump you install will need a hose to carry away the water. It is important to have this empty in a proper and legal location.
