The ProteKtor™ (PN PSD100) diffuses vacuum in any residential or commercial irrigation system that pulls fluids from a reservoir, canal, lake, etc. and can also be used in “trash” pump systems.
The ability of the gold fish to swim around the drain exemplifies the safety created by the ProteKtor from the intense vacuum which is created by the pump. This also exemplifies the inability to get entrapments with the ProteKtor in place.
The second video shows how easy it is to install the Vacuum diffuser system, along with adapter configurations.
