The 1600 Brine Valve Short Stem is commonly used in the Fleck 1500 and 2500 models.
The piston assembly ( part # 60029 ) should be replaced if the brine refill never stops.

The 1600 ( or 3/8" tubing size ) valve is normally used on softener tanks up to 16" in diameter.
Larger commercial valves will use the 1700 ( or 1/2" tubing size ), part # 60034 ( see our part 346003424 ).

NOTE: The Brine Line Flow Control portion ( 6002025 or 6002050 ), is sold separately, but you should be able to re-use the one you have currently.

Part numbers INCLUDED with this Assembly are one each of the following:
