Large air bubbles in 2nd toilet
Hello,
I'm having a problem with a 2nd bathroom toilet. I was unable to clear it approx. 2 weeks ago & the plumber came and plunged it and it seemed to be OK. Then it started "belching" large bubbles. This happened for a couple of days & then stopped. Now it's doing it again a LOT. In fact the noise woke me up this morning it was so loud & so long. I heard it again when my sister flushed her toilet on the next floor. I don't know if this was just a coincidence or what. Now the toilet's plugged up again. What could be the problem? It went almost 2 weeks without doing it.
Thanks for any help you can offer!
