    Hi.

    Could someone please advise me where can i find a " PVC Ball Valves Socket White 1-1/2 ". ( preferable for less than €10 )
    i am making a potato cannon.
    i have searched the net and everything i find is in America where shipping is €50 and up or a motorized valve for 70€.
    i have called to my local plumbing store but they only have them for flex PVC pipes.
    i am living in cork.

    Thanks in advanced.
    Rick

    Why not just use a standard ball valve with inserts and it will save you all the trouble,

    the potato cannon shoots potatos out of a pvc pipe. compressed air is used in my case to shoot the potato. ( wiki ).

    1 last question the pipe i got says
    polypipe 40mm waste pipe.

    He is right....

    If you told us the use at the start it would not have taken us as long to get here.

    How do you mean not have taken us as long to get here.?
    Is the pipe not suitable?

    Thanks

    You never said waste pipe. Nor have you explained propperly what your trying to do by pressurising waste pipe. This is not what waste pipe is designed to do and i doubt it will be suitable. Its back to old school science. When you increase pressure you increase temperature and volume. When you increase the temp of waste pipe it buckles. Additionally the solvent welded joints are not suitable for expansion and contraction.

    Your best bet is a philmac fitting. Although to be honest you need the pressure to be instant so if it were me i would be using an air compressor and taking a feed for an air controlled spring loaded ball valve that way you just push a button and the spring in the valve closes it off.

    This what you talking about?

    They can be made by using compressed air instead of fuel so maybe that is what the valve is for but these look simpler.

    the reason i got the waste pipe was because that is all that was in the shop. the video below explains how the cannon works.
