I have a short question...you know the hole in the base of the toilet (not the one that goes to the sewer) but the one opposite that about 3/4" or one inch, when working properly I think it helps push the water down into the sewer pipe. Well, mine is block because no water comes out. I have tried pushing thin wire in there to see if I could unblock it but the wire gets stopped like something is blocking it. Is there a way to unblock that little hole??
