    Default Repiping my two story duplex

    I am currently repiping my two story duplex from galvanized to copper 3/4. I am redoing all the plumbing in the basement and I will use the dioelctric fittings to connect the old to the new. I was planning on running a snake with a cut off end up the galvanize pipe leading upstairs to clean the pipe, then connect the two. I don't want to have to tear out walls to redo all the copper. Is cleaning the galv / with a snake affective and should I do it? What would you suggest I do?

    I would be suprised if you can do it.
    The inside build up is irregular and won't allow it.
    When it does start to leak in the walls you will have to deal with them anyway.
    I would change the exposed pipe and deal with the walls when the time comes. Who knows you may sell the house B4 that time comes.

    Default pipe

    The snake will not remove the internal corrosion, but if it does it will only do it for the first straight section. It will not turn any corners, and if the corrosion you disturb is sealing any former leak spots, you could create leaks.

    It is extremely common to repipe 2 story homes. It usually requires opening a few holes in the wall, but with proper planning, most of the holes can be under the cabinets, or in closets. Drywall patching is the least of your worries. Continuing to use the galv. could be a big mistake.

    Talking snakeing the pipe???

    Never heard of snakeing the galvanized pipe,

    and personally I would not attempt it...

    if the snake gets stuck or wedjed into some
    deposit , you are soooo totally screwed...

    and it will most likely make things worse..
    clogging things up beyond where you can reach...

    just bite the bullet and do it right or leave it alone..

    by completely re-doing the basement you will most likely help the
    pressure upstairs anwaay

    I am on board with the rest. I think you will have a hard time snaking the galvanized. When you cut the basement galvanized out, you should get a good indication as to what condition the rest of the system is in. Maybe you will get lucky and it is not too bad.

    Default GUEST , the long way is shorter sometimes.

    my 2 cents. Get this behind you ,all at once. Why re pipe up stairs in 5 years ? Do it all at once It,s all the same rusted pipe

    Look into pulling pex upstairs through the old holes. you'll have to open up some holes to do this . In the end, you'll be much happier
