    Replacing Filter valve and 3 way valve

    I recently replaced 12 year old single speed Pentair with a Super-flow Variable speed. Noticed some fine cracks pipes thread into filter valve and also I over tightned the old pump coupling causing a crack on suction side but does not leak, I will replace with new couplings that came with pump.
    • current filter valve is Pac-Fab TM12-A. Suggestion on replacement of valve and should I replace all internal parts
    • What 3 way valve is best ?
    • Currently has Nature 2. But I do not have a cartridge installed. Do not plan to use. Should I just remove when I re plumb ?

    Thanks in advance for any suggestions
