Eruption of water from toilet and kitchen sink.
Hello! I have a question or two that hopefully someone can help me understand. My brother lives in an apartment building in a city where his apartment is at the lowest level. (Namely the basement level.) He has frequent occurrences where his kitchen sink drain and his toilet will literally erupt like a volcano sending a jet of water one to two feet in the air. He's told his landlord about it and the man insists that there is nothing wrong with the plumbing, especially since the toilet flushes fine. I think otherwise. To my knowledge, there is no strong sewage smells and everything does flush down fine. There seems to be no blockages anywhere we know of. When the incidents occur, first there is a loud gurgle followed by a strong bubbling eruption. These incidents appear to be at random around the clock, but occur mostly in the wee hours of the morning. (Between 12:00am and 4:30am.) Has anyone ever heard of an incident like this happening? What would make the toilet and sink behave like that? Last question, is living in this apartment dangerous? Any help with this mystery will be greatly appreciated!
