SUMP PUMPS are automatic pumps used to remove ground water from sump pits. The most common application is to pump water from a pit located in the basement that collects groundwater from a perimeter drainage system designed to prevent basement flooding. Sump Pumps are the first point of basement protection. We have many varieties to choose from, which differ in construction materials, and performance specs. For complete basement protection, we highly recommend adding a Battery Back-Up system to your primary system as a second line of defense. The battery back up system, will continue the protection even when the power is out. WAYNE Pumps has made it extremely easy to obtain this full system protection, by installing a complete, pre-assembled combination system which is pre-plumbed and drop in ready for an effortless install.
