This is all apartment building gossip, but maybe someone can help out.
On Friday the the unknowledgable superintendent, who happens to be the landlord's son, was here "fixing" the fourth-floor's clogged kitchen sink.
Today the third floor people came home from a weekend trip and found "food" backed up into their toilet, clogging it to the point that they cannot plunge the problem away.
It seems that the clogged sink must have had something to do with this.
Did the super really screw up? We live on the first floor. Do we need to worry that this might have messed up the plumbing for the whole building?
Any advice would be appreciated.
Well if the plumbing was done correct this would not happen but in older buildings this could happen
When you run a snake in a line you push the food down the line into the main line if it goes down the main from the 4th to the 3rd well really in between the 2nd and 3rd floor what would happen is when the 4th floor uses the water it will go into the 3rd and when the 3rd uses water it will come back into there app- now for the 2nd and 1st your ok for now.
more then likely the weight of the water alone will push it right past you and you wont have any problems.(I Hope)
The problem with the 1st floor if the main line backs un in a building it goes into the 1st floor and the 2nd3rdand 4th all go into the 1st floor since it has no where else to go.
Now like I said in new buildings they are not plumbed like this so its not a worry.
I have been a plumber for 20yrs and there is a good chance that he caused this but then again he might not have. Rule of thumb when you do a app- and run (snake) a line on the 4th floor you make sure and go to the 3rd and make sure its ok and go to the 1st and make sure also. This way there is no doubt in your mind everything is ok
GoodLuck
I Had to edit this and say I love some of the answers people gave you. Just to let everyone know this can happen and it does happen alot. Most citys have changed there codes and how things are plumbed but some still let this happen so even now and then it will happen. This is a landlord that tryed to do the correct thing and just did not know what he was doing and what to do to make sure it was correct.
And the cost for only 4 floors running from the roof if you could get to it would be about 200.bucks or it will be about 150 to run from the main in the 4thfloor. Unless you have it HP washed (High Pressure) then It will be 300plus This is the best way and it will clean the pipe like it was new again.
