Thread: Bathroom Sink Drain (Broken from wall to Ground)

  1. #1

    Default Bathroom Sink Drain (Broken from wall to Ground)

    There was a clog in the bathroom drain so I took off the connections under the sink to unclog.... I cut the sheet rock to get to the pipe to see what I was dealing with I cannot find where the drain pipe went into the ground (or where the pipe actually broke) coming out of the ground. I looked and looked. The obvious answer is straight down... I thought I was going crazy but I cannot find where the spot where the pipe broke..

    I had purchased flexible couplings to reconnect the drain pipe but without seeing where the pipe broke I cannot fix. THe foundation is cement but the water supply lines that all come from the ground so the drain pipe would too, right? I am hoping someone can give me some insight here.. Thanks.

    Will have to remove the vanity to get in the wall to make the needed repair to the pipe. More work than I think is worth it than just calling a reputable plumber and the assurance that brings.

    Default Tough one

    I've demo'd a few of these. If you are a DIY'r and feel confident, then the fix is difficult, but not impossible. If not, hire a respected plumber.

    - Where the leak is showing isn't always where the actual leak is. Water tends to find the path of least resistance and follows the rules of gravity & capilary action. Sometimes leaks are obvious..sometimes not.
    - The lav drain, if next to a toilet prob runs towards the toilet.
    - If you can't determine which way the pipe bends, you could run a small camera down the pipe to see which way it bends (turns). Most camera's don't do small pipes well, but at least you'll get an idea.
    - You'll have to remove the vanity to gain access. Vanities are easy to move and replace. Be carefull of moving mirors.
    - You can rent a hilti demo hammer for approx $35 to $50 a day.
    - If you hire a plumber, remove the vanity yourself. No need to pay for that also!

    Do your homework & good luck!

    opps i had copied and pasted this and missed the most important part.


    Originally there was a clog

    When I was putting the pieces back onto the sink, the S trap, and the pieces that leads to the drain pipe behind the wall I was having a hard time the drain pipe that runs from the wall to the ground broke, the break happened near the bottom where the pipe leads into the ground...

    I had done some research on and found that flex couplings can be used to reconnect.. I went and bought the couplings but when I went to look through the hole under the sink I could not find where the drain pipe broke? I was thinking that the pipe should have gone straight down into the ground but when I look there is no hole or broken pipe. I just see solid wood and cement.. The drain pipe had to of gone somewhere in the small space...

    Also let me say I have great respect for plumbers and the knowledge that goes with the job.. I understand there are probably a million scenarios that would require me to call and a plumber and I would be more than happy to do just that. I know when I am in Way over my head.. As of now I feel like this is something I can fix.. I have taken on some pretty big projects before so this one seems easy enough, as of now, if it does get to be a bigger project I will call someone...
