    Don't use the crust, or multi grain type bread, and it will all be fine, eventually. You may get some hang up to begin with if it's a big ol' lump of white bread that makes its way down to the valve. But it should dissolve soon enough.

    I meant the bread trick.

    BTW, I *had* to use 12-grain bread once and it worked. I pulled out the sunflower seeds. The rest held fine.

    To others: after using the bread trick, flush it out by opening the closest hose bib, or closest faucet COLD WATER ONLY with the strainer removed.

    Oh, then in that case, yes I have tried it and retract my no statement. :)

    This unit that I linked to is designed to stop the flow for PRESSURIZED lines. The bread trick ain't going to work on that.

    A co worker that I worked with in plumbing has used it on 4" pipe. He said it worked really good.

    I think he said it take to long. He said he was changing out a butterfly valve in a hospital. He said he just had to look in the pipe to see that.
