This fun little annoyance started a few weeks back after working on some of my plumbing. I moved a toilet in an adjacent bathroom, to include rerouting some DWV piping. The two toilets share a vent stack. The water from the bowl is siphoning out. Not completely, but it is obvious that it recedes once the bowl finishes filling. The other apparent issue is that it's readily siphoning while filling the bowl.
I've included a youtube link of the problem. Does it seem likely this is a clogged vent line, or could there be another issue?
