Thats true what hj said. Water is stupid. You may want it to smartly go where no water has gone before and not go where it should not go but then you have that dang stupid thing going on.
That's why the first thing they teach us plumbers is what day pay day is. If'n you didn't know that one, you'd be spending lots of time putting the worry to it. But that's not the thing that water is worrying about. It wants to go downhill all the time..... that's right, one of the other things plumbers have got to know is not licking your fingers. That and water being stupid and all just wants to go downhill. Me.....that's why I get the big bucks, I know where it goes.

: As soon as the pump started, your piping would become its drain and the water would enter the sewer system. Apparently that would be illegal in your area otherwise the pump would have been attached to the sewer system originally. Water is stupid. It takes the easiest route and would not remember it was supposed to go all the way up to the roof and drain to the outside.

: : I'm adding a sink and washing machine to a basement. I can easily drain them into the main stack. But finding a place to vent each is difficult. Nearby is a sump pump and a 2 inch drain pipe that goes up to the ceiling, accross to the outside wall, then down about 6 feet, and out the back of the house. Can I tie the new vents into the sump pump drain--even though it goes up and down--since the end of the drain is outside?
