    hI all, I have just recently connected my ATO to my APEX. was working fine for a few days. now it will not turn on the pump. and the FMM box keeps making a clicking and the pump never kicks on.

    Check for obstructions. That clicking means the pump stalled.

    ok,I'll take another look at the PMUP. Is there a way to tell if the PMUP is shot?

    I dont see anything, blow the lines out, checked all connections, and even look for a software update. Maybe the pump itself?

    I'm on my 3rd PMUP in my RO/DI reservoir in less than 1 year. I now keep a couple extra PMUPs on hand in case another one fails. Neptune has replaced the failed units under warranty.

    that's for your comments, So when your pump went did the green light flash and you can hear it clicking on an off. Is this what you experienced

    On one PMUP that failed, I did hear clicking, but I'm sorry I didn't notice if the green light went on and off. On the other failure, I could just hear the PMUP humming/buzzing but not pumping any water.
