Water Softener backwash
I need some help with my water softener. I have a fleck 2510sxt on a 10x54 tank with about 1.25cuft of standard resin.
The problem I'm having is the backwash mode is only expanding the resin by about 9 inches during regeneration. I have 4-5 inches of gravel in the bottom of the tank and about 30 inches of resin. Everything I read says that I should be achieving a backwash expansion of 50% or more (15+ inches).
My current DLFC is 2.4. The drain line has a vertical run of about 4ft before going horizontal for 15 ft to the air gap drain. Drain pipe is 3/4 cpvc. Will increasing the DLFC to 3, 4 or 5 improve the bed expansion during backwash?
