Plumbing Problems

Sunday night I had gotten home from my Mom's house from having dinner.  I had gone up stairs to use the toilet and when I went to flush I noticed the handle was very loose and would not flush.  So I took the top off of the toilet and quickly saw what the problem was and fixed it.  Awesome its working now!!  OK so the night ends and its time for bed.  I wake up the next day and have breakfast and take a shower.  Later while I am doing the dishes I hear water to my left.  I look over and see water coming out of the hookup for the washer (we don't have a washer).  After a few seconds the water stops flowing out of the washer hookup.  My brother is sleeping in the living room on the couch.  I ran over to him and woke him up so I could tell him about it.  I am wondering what the hell is going on and why the water is coming out of the washer hook up.  My brother goes to the bathroom and I can hear the toilet being flushed and more water comes out of the wall where the washer hookup is.  Its coming out pretty fast and stops after a few seconds.  I called my brother downstairs to tell him that we can't flush the toilet till we get this fixed.  So I got the towels out and cleaned up the water and went to work.  My brother called the land lord to come and fix the water problem.  When I got home it was fixed.  Problem solved yeah!!!  Later that night I go to do the dishes and the water in the sink won't go down the drain.  I try using the garbage disposal and the water goes down the drain and when I turn the garbage disposal off it comes back up.  So I'm thinking shit we have another problem.  I knew that if they were going to fix it in the morning that I had to do the dishes so I did the dishes and went to bed.  In the morning the water was down the drain.  I think good the problem is no more.  So I take a shower and shave and I start coming down stairs and I hear dripping.  I am thinking shit what the hell is going on?  So when I get to the bottom of the stairs and step on the tile floor my foot touches not a dry floor but a soaking wet floor.  The hall way is flooded along with the kitchen.  The sink is full of water that has overflown on to the floor and counter.  Water is every where.  I am flipping out and cursing up a storm.  Not happy at all!!  I used all the towels in the apartment to clean up the water and then I wake up my brother telling him about the flood.  He says OK I will get up at 6:30 and give the landlord a call.  So I do what I can and leave for work.  Later at work on my break I call my brother to see if the plumbing problem has been fixed.  He tells me they are working on it and that the apartment to the left and on our right both are having the same problem.  So something went wrong and I don't know what it was but that was really a pain in my ass but I was not the only one to have to deal with a water problem.  I later received a call from my brother telling me that the problem was fixed and that tomorrow (Friday) the landlord would be sending over someone to shampoo the carpet.  I said why because the carpet did not get wet?  My brother says well they are doing it as a courtesy.  I thought wow that's really nice of them.  So now its Friday, and I got home from work about an hour ago and I can see the carpet people were here and it looks great!!  The water has been working fine since yesterday and its still working the way it should.
