An engineer is designing a new residential sump pump. Sump pumps are used where basement flooding happens regularty and to solve
dampness problems that can occur if the water table is above the foundation of a home. Sump pumps move water away from a house to any
place where it is no longer problematic, such as a storm drain or a dry well.
There are four factors that the engineer is considering for the design:
1. Whether the pump is a submersible or pedestal pump. Submersible pumps are put underwater in a sump pump basin, and pedestal
pumps are positioned with the pump motor out of the water, above the sump basin.
2. Horsepower, either 1/2 hp or 1/3 hp.
3. Material, plastic or metal.
4. Type of backup battery, gel or lead-acid.
An experiment was conducted to test the number of gallons pumped before there was noticeable pump failure. Pump failure occurred when
the pump did not pump out at least 90% of one-gallon for every one-gallon input, if there were noticeable leaks, or if the pump completely
failed. The pumps were set up to run continuously until failure. In areas where a sump pump can be used continuously, the longer it lasts
An engineer is designing a new residential sump pump. Sump pumps are used where basement flooding happens regularly and to solve dampness problems that can occur if the water table is above the foundation of a home.

Pump failure occurred when the pump did not pump out at least 90% of one-gallon for every one-gallon input, if there were noticeable leaks, or if the pump completely failed. The pumps were set up to run continuously until failure. In areas where a sump pump can be used continuously, the longer it lasts before failure, the better the design.
