Kitchen sink won't drain, unless I turn the garbage disposal on.

Drain pipes are clear.
I just bought a new disposal.

Could it be a venting problem? If so, what would cause it all of a sudden? (Been working great until today...)

Other suggestions?

Is the disposal clear. Unplug the disposal and reach your hand down in there to see if there's anything to clean out.

Garbage Disposal Problem

VERY clear -- It's brand new, but the problem continues.

Even the dishwasher still properly flows into the sink, but the sink won't drain, unless I switch-on the Disposal to suck the waste water down.

Other thoughts?

Sounds like you will need to clean the line out, could be partially plugged up.

I snaked the line today - it was pretty clean.
Trap was spotless.

Can't figure why it drains easily when the disposal is turned on, but won't drain at all without it.

Any other thoughts?

I don't know, is the drain pipes from the outlet on the disposal, to the trap, and out the wall, all graded to flow downhill?

Yes, everything is graded & was working perfectly until last night.
I thought it was a blockage, so we checked the trap & snaked the line. Thought the disposal might have gone bad, so I put a new one in today.

Ever hear of a possible "vapor lock" type problem, which might prevent gravity drain? I'm outta ideas...

You could check for a vent blockage.

On a new disposal the rubber spash guard between the disposal and the sink restricts the flow of water out, but only until the water enters the disposal it's self.

Fill the sink all the way up and pull the plug, don't turn it on, now push in on that splash guard, does it drain out faster?

If not check out the vent.

Thumbs up

Great minds must think alike.
I climbed up on the roof, & went into the vent from above.
Found a blockage, cleared it, now working like a charm!
Appreciate your help -- Do you renovate bathrooms, too?
We're looking to hire a smart man who does good work!!
Thanx again!
