This is a little long, but PLEASE, I need some advice.
So we live in a 3 story apartment complex.
Ever since we moved in, one of our bathroom toilets periodically gurgles.
When it does, the water level goes down. During this time, if you try to flush the toilet, the water just backs up in the bowl.
It will eventually slowly go down or sometimes flush very suddenly.
About 2 months ago our toilet started spewing sewage into our bathroom.
I also had sewage coming out of the sink and bathtub!!
I finally was able to stop it by plugging up the toilet, but not before I had about an inch of sewage water in my bathroom.
The complex had to replace carpets and send professional cleaners out.
They claimed that since we were on the first floor, there must have been a clog somewhere and we were the unlucky ones since we are on the first floor.
Well, the problem still persists. The toilet gurgles every couple of days.
I'm afraid to leave my apartment!!
Whenever I do, I plug up the toilet just in case. The apartment complex says there is nothing wrong as their maintenance crew cannot find a clog anywhere.
Is something wrong with the plumbing? The building is only 4 years old and rather new. Perhaps something was connected wrong?
Should sewage have spilled out of the sink and bathtub?
I do not have any problems with my other toilet and it has never gurgled.
What should I do?
I remembered some more details. I can sometimes hear water going through the walls. I assume that one of the neighbors upstairs flushed the toilet or released some bath water. This is another time when the toilet will gurgle. Also, during my toilet sewage spill, the water was warm? As if somebody released some bath water and that was the reason for the backup?
Still, don't apartments have recourse for this, like a one-way valve (if one exists? I'm no plumber so I wouldn't know)
