Abstract

A system for circulating water between a container and an external system in such a way as to maintain a desired water level in the container may include, an overflow assembly and a return assembly. The overflow and return assemblies are generally tubular structures, each of which includes a pair of concentric tubes. The overflow assembly typically includes a skimmer and a silent overflow device towards its upper portion, as well as a strainer towards its lower portion, wherein water is taken out of the container through the skimmer and/or the strainer. The return assembly typically comprises an upper capped diffuser and a lower diffuser, wherein the former allows for water to exit into an tipper portion of the container and the latter provides for water inflow at a lower portion of the container. Both assemblies are installed inside the container by attaching to a lower wall of the container.
