For a half hour after I use the shower, a strange loud slurping noise comes from the pipes. It keeps getting louder and louder, then stops, then starts up again for about another hour.
I have a question, are you on a septic or city sewer system? I would also add that you should post this query on the Plumbing forum.
Clog slowly burping in the drain?
Try a plunger.
I dont know what it is but I would keep my toes away from the drain, it sounds hungry, sorry I couldnt help it...lol
You waste pipe might not be vented. That causes a slurping or gurgling noise as the water does down the pipes. Common in older houses.
I don't have anything to add to this. I just wanted to see why people resurect nine year old posts.
