In response to Re: kitchen sink drainage problem
: : In the process of remodeling a an upstairs bedroom i replaced there was a 1-1/2" vent stack running from the basement through the first floor kitchen up into the bedroom upstairs, at the floor in the bedroom the vent makes 2-45 degree angles with about a 6" piece between and then upwards and switches to a 3" pipe through the roof.

: : Ther pipe was rusted through, so we decided to replace it, we added a 3" piece protruding from the roof down to a rubber 3" to 2"connecter, then a 2" to 1-1/2" connecter and then into the origional metal piping(went from 3" to 2" to 1-1/2" because we could not locate a 3" to a 1-1/2" connector), eventually we will be switching the entire pipe to a 3" all the way to the basement , which will eventually have a toilet, shower and sink added in, but the problem now is that the kitchen sink no longer drains. Could the size changesds on the vent make this happen and if so will there need to be another vent added when the batroom changes are put in?

: sorry for my spelling but it is 1:30 am here and have been going fighting with broken water lines to the kitchen sink(with no shut off valves except the main) and a leaking trap that needed to be replaced.

I hope you installed individual shut offs while the water was off.
The vent repair itself (the size change) did not cause the kitchen sink problem. I would be inclined to believe that you broke something loose inside the pipe that dropped down the stack, clogging the kitchen line. Bad or non existent venting does not cause fixtures to not drain. Clogs in the drainage line cause things to not drain.
You will need more that simply adding another vent when you get to the basement bathroom. Venting for multi-floor homes gets more complicated. Vents will need to be run and other things may need a revent. Consult a licensed plumber when you get to this phase.
