Toilet started clogging frequently and required plunging after every other use. Used a toilet snake to clear possible obstruction. After using snake, when toilet is flushed it immediatly makes a pronounced burp and then seems to flush fine. Sometimes the burp is strong enough to splash a little water outside the bowl. I have a septic system. What could be causing this? Thanks for any possible solutions!
