My toilet is making a slight gurgling noise at the end of the flush. Here is a video of the flush: https://photos.app.goo.gl/yIcFN14zdgDAAFu43
I am wondering if I should have put the vent coming in the back of a sani-y instead of meeting up with the toilet post 45 elbow. Would this have been a better solution:
Or is there a better solution out there?
