Customers that have a new or existing pond but want the same fantastic benefits that a bottom drain gives you, without having to rebuild your pond, were the target market for the Weighted Suction Dome Range.
The water circulation around any pond will be significantly improved by weighted suction domes once they are linked. Reduced maintenance is the result of the enhanced water circulation that helps remove dirt and suspended particles from the bottom of your pond.
There is no need to dig a hole or make one in the middle of your pond liner. Put it there simply, in the pond's lowest point. A weighted suction dome operates in a manner very similar to a sump drain, drawing sediments and detritus from the pond's bottom right into the filter.
The Weighted Suction Dome line is simple to maintain and clean, and each model is equipped with a Base Plate that is positioned at the ideal height to provide the most draw across the pond's bottom. Therefore, there are no concerns about flow limitation even if the bottom of your pond is not perfectly level.
