Water Draining Slowly - Is it Because Dishwasher is Attached to Disposer?
 
We just had our basement finished. We have a single bowl sink in the bar area. The dishwasher drain hose was connected to the dishwasher port on the disposer. When the water is running full blast, the water level rises to about the top of the drain. When I shut off the water, it then drains relatively quickly. Is it normal for the water to drain somewhat slowly when the dishwasher discharge is connected to the disposer?

A dw discharges a lot of water very quickly, and it is not unusual for water to "back up" to the top of the drain, disposer or not, while it's pumping.
All is OK. Don't worry about it. Just for drain maintenance purposes, I pour a little DrainCare enzyme-based, non-caustic drain cleaner down my drains (toilets excluded) from time to time. An enzyme-based drain cleaner will eat out all organic gunk without harming the fixture or the pipes.

Thanks for the response, but I forgot to mention that the plumber just finished the hookups so the dishwasher has not even been turned on as of yet.

How far from the drain is the vent?

The PVC vent is at the back of the same cabinet that the sink is in. So, it's within 12" of the center of the sink. I also have a bathroom sink, toilet and shower on the same venting and they all work perfectly.

Do you use this enzyme-based drain cleaner for your washing machine drain also?

Sounds like there might be some debris in the garbage disposal, I would unplug it and feel around in there for anything out of the ordinary. Lots off things could have fallen in during construction.
