I live in a multi-unit condo on the first floor. There is one common sewage pipe that connects all of our toilets.
One night, my toilet (only one) won't flush. A little bit of water began to seep out of the base. Water starting to back up as in my bathtub as well.
I asked my neighbor and she said he was having problems flushing the toilet as well.
So I called the plumber. He came and proceeded to the outlet where he could ran a snake through the pipes. But after he opened the cap, the stoppage cleared and we could flush our toilets! He didn't do anything! He just opened up the cap!
What could cause this temporary stoppage? Air back pressure? But shouldn't the air outlets on top of the roof handle that?
Thank you in advance for any insight.
These stoppages have been occurring on and off for several years. What can the HOA do besides running a snake and jetting the pipes to prevent these sudden stoppages?
