    Hi peeps

    So I bought the the JBL m502 solonoid kit and it came with a 2 in 1 drop checker and check valve.

    Good Quality plastic
    Seals well (has threaded nut so line can be locked in)
    clearly marked on intput and output
    Easy to see the bubbles

    The mounting bracket does not stick very well - these suction cups seem worse than others
    Check valve doesnt work - I only realized a few days later as water went missing so I added a check valve before the unit and it seems to have helped

    Would I buy it, probably as you can see its quality but you do need a check valve

    Here is the water that has disapeared

    Was the original the solid black check valve ?

    If so I have found they work just fine at a high pressure .... but if you reduce the flow they do not handle tweaking very well.

    If you are using the JBL Thaifun - I am OK with counting the bubbles from that.

    JBL was my first CO2 kit- and the stuff still works.

    Later Ferdie

    PS really like the fact that you are reviewing stuff - TASA needs more of it, good job.
