If conditions prevent installing additional traditional through-the-deck drains, the alternative way to effectively reduce a ponded area is to install a self-sufficient, solar powered (PB-2000) pump unit.
The PB-2000 system is a totally enclosed, uniquely designed water pumping system that acts as an auxiliary drain. The self sustainable unit is placed at the lowest point of the ponded area. When the ponding water reaches a critical depth,the solar powered pumping system automatically activates and starts the draining cycle. Flexible drainage lines are run from the PB-2000 into an existing roof drain, downspout or over the edge of the roof up to 100' away. The PB-2000 will pump up to 36" in a vertical application, like a parapet wall. The unit will effectively remove up to 95% of the total ponding water under normal conditions.
Available as a single component unit (PB-2000S) and as a two component unit for hard to reach locations (PB-2000T).
