I was hoping you could help me with a general question about my 2nd floor toilet operation. My TOTO toilet creates a gurgling and/or choking sound when flushed. I have research this problem and found that it maybe cause by improper venting. I also conducted a 2-gallon bucket test and got the same noise. I repeated this test on my neighbors main floor TOTO toilet. The flush worked as designed without any gurgling noise or a choking sound. The water from the flush completely cleaned the bowl.
Could you please tell me what the proper code and/or requirement is for venting a toilet. I believe my venting system is tied into the sink, shower and maybe another bathroom below this one.
Thank you
