when bathtub drains, it overflows sink!!!!

my upstairs bathtub and main level bathroom sink are on same line. when the tub drains the water overflows into and out of the sink. when you open the drain on the tub, you hear gurgling from the sink. it only started doing this 3 weeks ago. this line doesn't tie into the main sewer line in the house, it runs out the basement wall and ties into the main sewer line outside. the plumber snaked the line and found nothing?????? ANY help is greatly appreciated!!!!

Sounds like the plumber totally missed the clog. Have him/her come back at their cost to correctly diagnose the location of the clog and remove it. Sometimes repeated passes with a cable, bending the end of the cable will remove the obstruction.


Sounds like he/she trailed a vent instead of the downward turn of a sanitary tee; very possible scenario and bending of the cable will remedy this problem of dropping down into the tee.


Short of a drop-head attachment, but those are not common with the smaller diameter cables. (1/4") < I always use open hook with the end bent @ a 45 degree angle.

Bath tub drain problem

jwalker9 is the sink on the same floor? If it is I don't have a clue what is wrong, but if the sink is on a lower floor, Dunbar Plumber is right, you have a clog.

no the sink is on the first floor, tub on second. the tub is directly above the sink. the sink ties into the same drain pipe as tub and outside, connecting to main sewer line.

sink overflow

jwalker9, you have answered the question, you have a clog. Its running out of the sink because it has nowhere to go. The stopage is below the lower sink, if you have a way to rod at this point thats the way to go. Luck.
