I have a bathroom sink that has been a constant problem since we moved in.
We've called the rooter guy out several times, and he's run the auger through and cleaned out the clog. This lasts for about a month, and then it's back to abysmal.
We've also tried getting the clog buster rubber doohickey and running water through it ourselves, with the same basic results - it clogs again after a month.
My husband even got on the roof with a water hose and ran water down the vent, to make sure we didn't have something blocking it - and ended up running a lot of water into the bathroom. But at least the vent isn't clogged.
We think the clog is between the sink and the toilet, because the toilet has no problem draining, and the tub is fine too. What could possibly be the problem? Any help will be appreciated - I'm just about to go mad!
