NOTE: # 2 Gray ( Grey ) PVC
is commonly used in residential sized ( tanks 8" - 12" ) systems that use Potassium Permanganate ( or in some cases liquid chlorine / bleach ) as the "Regenerant" that is drawn into the Valve Head.
These are either Iron Filters using Greensand, or Carbon filters that "regenerate" with the chlorine / bleach solution.
And these PVC versions can last / hold up 3 - 4 times longer than the standard plastic Nozzle & Throats used in water softener ( Brine / salt water ) applications.
The # 3 Gray PVC
is only used for larger tank diameters of 13 - 16 inches, and that would be a light commercial application.
Cross References = ( 10027XB and 10028X ) - many similar valves sold under Brands such as MacClean, CUNO, and Aqua Pure,
That are really their versions of Fleck 5600 or 2500 models.
