    Moisture from leaking flare nut?



    I was at a site where the sight glass was yellow, the system kept on pumping down every few days and i also found the suction flare nut on the TEXV had a leak.
    I fixed the leak, changed driers and evacuated and all is good.
    My question is how can moisture get into a system via a low side flare nut without the system runnning into a vacuum? The system in running on 134a and is a coldroom, the LP switch does cut out above 0psig.
    Can the refrigerant drag in moisture (venturie effect)???

    Re: Moisture from leaking flare nut?

    Thanks for that..... I did have a seized condenser fan motor a while ago on the system. Once Ive replaced the fan motor and pressures returned to normal would the existing driers have reabsorbed the moisture over a period? (If they had released the moisture)

    So .... could a leaking TEXV (on the suction side) , while still being in a positive pressure, drag in moisture as well?
