The new module is the advanced 255 design ( the 155 was updated in late 1995 )  and includes new o-rings for mounting to your tank adapter ( the part which connects to your resin tank, your plumbing, and your brine air check assembly ).

This is the complete upper body with all new flapper valves,  injector, screens, & brine control.

Everything from the tank adapter up!

Add another 10 -20 years of life to your water softener ( the resins, and tanks will last 40+ years under normal conditions ).
