Description

Master Spas X278925 DSG Single Filter Weir Assembly

The X278925 is a genuine Master Spas weir assembly for DSG-style single-filter housings used on Down East series hot tubs. The weir door creates a surface-skimming action that draws in the top layer of water, trapping floating debris at the filter while preventing it from flowing back into the spa.
