The washing machine discharge should be connected to that pipe. I'm not sure
what you mean by directly. There must be a "trap".

I have one of these http://www.oatey.com/quadtro.html that the hose hangs on
then there is a standard trap below...

See how it was installed

See the trap, near the floor, then the vent going out the roof.

well, I found out not to vent the dryer to that pipe. however, I as i
said before the washing machine is piped directly to that drain. is
that allright? also should it be a direct connection?
