bathroom sink drain
Posted by Donald Smith on December 01, 2002 at 13:51:11:
My bathroom sink drain makes noise after the water is gone out of the sink. kind of like glub, glub, glub.
I thought it was because i do not see a vent any where in the septic system. I replaced the pipes with plastic and added a 18" extention from a Y. The other side of the Y I took to the trap under the sink. It still GLUBS after the water is out of the sink. the trap is below where the trap goes into the drain pipe.
Any advice? Thanks
