Hi guys,
I'm new to this forum and am looking for some suggestions regarding a s-trap underneath a newly installed sink. The problem I am having is that the sink drain makes a loud gurgling sound after water has exited down the drain pipe. If the s-trap is removed, the gurgling sound does not happen when water is draining. I have a suspicion that the sound may have something to do with the drain pipe from the sink leading to the main soil stack being too long and too vertical. It measures about 14ft long and it seems to drain just fine. What are my alternatives to a s-trap? Any thoughts on the cause of the gurgling sound? Thanks in advance for any input...
