I live in an older home and have a tub and bathroom sink that drain very slowly. When I drain the sink, I can hear a gurgling in the tub drain and, when I put a lot of water down the sink drain, some water will come up from the tub drain into the tub. I've been putting some Drano down the drain every two months or so, but am worried that this may damage my pipes in the long run. I also have tried to get a snake down the tub overflow, but don't think I'm even getting past the elbow that turns from vertical to horizontal under the tub. Unfortunately, the first floor ceiling underneath the tub is finished, so I can't really get at the trap (I'm assuming it's a drum trap). So, 2 questions:
- Is there a secret to getting the snake past that first 90 degree bend? I'm able to get the snake through sink P traps with no problem, but can't really figure out what's catching the snake under the tub.
- Are there any other solutions other than the Drano that are less likely to damage my pipes, but work for more than a couple of months?
Thanks in advance.
