    check valve replacement in mini split heat pump



    Hi guys
    i got LG mini split heat pump
    it has bad check valve

    so i removed it
    but here we dont have spare parts
    s what i can do then

    here is the ac unit diagram for cooling only no heating





    here is both heating and cooling
    so u can see check valve in heating only also an addition capillary




    Power consists not in being able to strike another but in being able to control oneself when anger arises

    without parts I cant see a way round it mate

    maybe if you have an old solenoid valve and a relay

    the bypass solenoid can be wired to the normally closed side of relay so when the liquid line solenoid drops out this kicks in

    only other thing can think of is a shut off / isolation valve but that means you manually switching from cooling/heating mode

    will message you on facebook if I can find one in my garage and see if I can post it to you
