Here's a strange one. When I use the sink in my guest bathroom, water
comes out of the bathtub drain in the room. Then it just sits there
and takes forever to drain. What's going on? Can anyone shed some
This may sound dumb, but how do I check the vent? I assume you are
talking about the pipe that runs to my roof? It runs for 30 feet or so
through some of the rooms in my house and comes out on a deck at the
top of my roof. How could I check to see if it is blocked?
Also, should I 'snake' the drain myself or should I call a plumber?
I've never done any of this, but I am *somewhat* handy.
Sink and tub drains come together at some point downstream. You have a
blockage past the point where they come together, and/or a blockage in
the vent that goes to the roof above the bathroom. Does the toilet in
that bathroom flush properly, or gurgle? If it does work properly, and
the toilet drain ties into the other drains below where the tub ties in,
that tells you pretty well where the blockage is. Try one of those
2-part drain cleaners down the tub and the sink. Probably a hairball
plus soap scum. If that doesn't work, it is time for a snake or roto-rooter.
