    Put a ball valve at the bottom of the tank to stop and regulate the sand flow.
    X2 That is exactly how they are setup.

    Secondly, the best investment I ever made was a carbide nozzle for the blaster. They don't wear very rapidly so you don't lose the blasting capability as you do with a ceramic one. I've had the one I currently use for several years.

    That style deadman uses a block across the nozzle that wears almost as quickly as the nozzles. Make sure to get extras. Also, the sand will still flow into the hose and you'll shoot a lot pure sand for several seconds before the hose clears. Put a ball valve at the bottom of the tank to stop and regulate the sand flow.

    There should be a main valve at the water separator/main inlet, a second valve after the line comes out of the tank, and a third valve at the bottom of the tank to stop the flow of sand. Shutdown is sand 1, air to nozzle 2, main inlet 3. Depressurize tank before opening to add or peer in to check abrasive, don't ask me how I know.

    Hi Jerry
    I think all that would do for me is to delay the sand belching from at the time I stop to the time I start again.
    Would that reduce the amount of sand splurting out?

    Also I knew about the avalability of the dead man valve, I may use it if there is no good solution
    to my original question.

    Thanks
    Paul

    Experienced sand blaster?

    I have a home made sand blaster.
    It holds over 100# of sand.
    It works great and have used it for years.

    The only thing I don't like about it is that when I shut off the air,
    it continues to belch sand until the air pressure diminishes.

    The sand for blasting comes out at the bottom, so can I plum another valve some where
    near at the top to let the air out after the inlet air is shut off?

    I lived with it this long, but as I get older more things annoy me.

    Thanks
    Paul
