bathroom sink will not drain fast

JuliaGloria MonroeWoodbridge Environmental


we moved into a home that one of the bathroom sinks will drain very slowly, we can plunge it until the water is all gone but this happens to be the bathroom that guest use. We have taken the pipes apart under the sink and nothing clogged there. I have tried to use a snake in the pipes in the wall but there is a turn and my snake will not make it. Can you give me a suggestion. I have even went as far a plunging drano thru the pipe and that didn't help

  • The plug is past the wall tee. IF you are using a small snake and it cannot make the bend, the trick is to help the snake go around the corner. In order to do this you will need a small length of 1/2" copper pipe about 12 inches long. and one long sweep 90 or 45 degree elbow. connect the elbow to the pipe, you can use duct tape to hold the pipe and fitting together. Then push the snake into the pipe until it begins to come out the other side of the elbow. Then push the entire pipe and elbow into the pipe until it hits the back of the Tee in the wall. Then continue to use the snake as you normally would. The elbow will cause the snake to make the bend and continue to the plug.

    Perhaps the bathroom is not vented properly. Check the plumbing stack penetrating the roof.

    I have also flipped my snake 180 degrees and use the tail end in which I put a hard bend. it is important to rotate the snake during use...

    I recently had a problem with drains. When I checked my vent pipes on the roof there it was a walnut stuck in by one of the little grey guys in the neighborhood! Laughing out loud not but not at the time.

    I climbed in my attic and could not find the pipe for this sink

  • Susan the vent pipe may not be visible in the attic. It often is combined with several vent pipes and ran out through the roof. So the pipe your looking for might be four inches down to two inches in diameter. Sometimes it is right along the wall by the bath, other times it is piped across the ceiling or through the walls to another location were you may not be looking. In any case your better looking for it outside on the roof. As there is no access to this pipe in the attic anyway. How old is the home? Have you ever noticed a glub glub sound when the toilet is flushed? What about the tub or shower? If your hearing that type of noise then it could be a vent issue. However I still think its a plugged drain line past the fitting in the wall where the pipe exits into the room to attach to the sink.

    everything else works fine, I will look more tomorrow, thanks for replying! Getting the best of me, we were told the home was built in 1970s it has been added on several times. I think this bathroom was one of the add ons. The toilet and the shower work great

  • Then there is no vent issue. Something is plugged somewhere beyond the reach of your snake.

    turn off the water under the sink then take the pipes apart there has to be something caught in there, dont forget a bucket under the pipes where you are working

    i had the same problem and found that the pipe going into the wall was going to a t and not a swipe t this causes the water to drain but very slow there is also an air vent you can put in with out going thru the roof check this out at your hardware stories. [
