Abstract (en)
[origin: US2017254333A1] Design solutions to mitigate the following four fatal flaws in the conventional pump system design; namely, (1) surprised pump-failure in single pump design that can result in costly water damage; (2) the threat of fatal high voltage electrocution accident in flooding situation; (3) grid power outage and no energy supply to support the needed pumping power that result in water damage; (4) stinky smell from the sitting foil water in the well after a period of low seeping rate with or without activated pumping. The principles described in the content disclosure, the proposed designs can completely mitigate the above four fatal design issues.
