If your house was built on a flood plain or a very flat field, you'll find out soon enough after a bout of heavy rain or snow showers leaves you with water pooling in your basement. Installing a sump pump may be the most efficient way to solve the problem. The sump refers to the hole dug out of the basement floor in order to hold a pump that can move any water that accumulates up and away from the foundation of your house.
You can install a pump of two different styles of pumps. The first is a submersible sump pump that is positioned at the bottom of your pump hole .Since it's submersed in water, it's a pretty quiet model to run. But the submersible pump is more expensive than your second option, a pedestal pump that keeps the motor elevated out of the water via a standpipe. Although it's less expensive, it tends to be very noisy.
Find the lowest point of your basement floor that is located near an exterior wall and an electrical outlet to plug in the sump pump. Don't forget that you need to run a pipe from the pump through the exterior wall to the outside of the house to dispel the water.
Use the sump pump plastic liner as a guideline for how big you will need to construct your sump hole. Dig your hole about 24 inches deep and make sure the bottom is level. Put your sump liner inside the hole, making sure it's a secure fit and on a level field with the floor, using concrete to fill in as necessary.
Now you are ready to put your pump and discharge pipe into the pit. Cut and position a hole in the wall for running the discharge pipe through, leaving about 4 inches of pipe inside the house and half a foot of pipe outside. Once you are sure the pipes fit properly, cement them in place and seal the area around the discharge pipe with caulking. Make sure that the water will be diverted away from your house's foundation by at least six feet.
Check to be sure the pump's float valve is adjusted according to the manufacturer's directions, then plug your pump into the electrical outlet and fill the hole with about 10 gallons of water. When the water reaches a certain level, the float valve will activate the operation of the pump, pumping the accumulated water in the hole through the discharge pipe and outside the house.
