Fleck 2510 clock unit
My current softner is going out so I stopped out to talk to a water softner dealer and he is suggesting a 2510 fleck 48k clock unit. My hardness is 22 gpm with 3 ppm iron. He said I ahould be recycling every 3 days and Its just me living here. Is there anything else I should adding to this system? He wants $849 if I install and $899 if he installs. I found the same unit online for 519 with free shipping. Please comment on this.
