Repairing my Dynasty spa that froze during winter, 2 years ago. First replaced the control unit, which burned, then cracked pump before I found the PVC flanges had also cracked. With so much invested in repairs already, I dont want to trash the thing. Have replaced the ports, and busy with piping now. The problem is that the drain faucet is not the lowest point of the system. The 5 port flanges are, and never drained. Is it worthwhile to put in 2 new drains? If so, using what? 2" piping at this point. Second, the "diverter" if that is the correct term, for left/right water supply is also cracked around the threads. Not the housing, so is it possible to just change out the mechanics, without disturbing the insulation and piping below? Can someone point me to a new "diverter" of the same type? What foam spray can I use to replace the foam I stripped away?
Many thanks.
