    Default Dive Tank valve - Dip tube

    I am busy assembling a new fibre tank.

    The purpose or the dip tube (pin at the bottom) on the valve is to block any water from a breathing apparatus. Very helpful for firefighters that wear their bottles upside down.

    Would it not be a good idea to leave this tube out when assembling. You can then periodically after a dive bottle fill hold the bottle upside down and purge some water out.

    If you get water in the tank , you have a much more serious problem.

    Its also to prevent any solid particles from entering the regulator. A stuck regulator under water or in an oxigen deficient area can be deadly. Rust in the filling equipment or cylinder is the biggest risk.
    Rust is the firts thing that is looked for during a visual inspection.

    Luckily we are not underwater shooting
    so its not needed
    and dont presume that commercial dive shops always have dry air
    I have experianced were my steel bottle had to be cleaned and treated for rust
    it had always been filled commercially and only by this supplier for the previous 4 years
