Injector/ Drain Module For the Fleck 5600 Softener Valve
( includes new injectors, new o-rings, and .25 gpm BLFC and DLFC based on tank diameter ).

Since a 9 inch tank is the most common, we will send the module with a 2.0 gpm DLFC ( drain line flow control ) button, unless you specify a different size tank diameter.
If your valve is used for something other than a water softener application, you need to tell us.
Backwash only and Iron Filters use larger DLFC buttons. And we have a Separate Item Number for the Version used for those application ( PN 34600841281 ).
