Dishwasher drain

Can a basement dishwasher be drained into the sump pump pit?

It depends on where you are located but most areas these days that have building codes require it to go into the sewer. Your sump pit likely pumps out onto the ground somewhere. Long ago it was rather common for clothes washers and even the occasional shower/tub (gray water) to be dumped on the ground but no longer.

I have to agree with Dane.

But in the event that you find out otherwise.... you need to still elevate the drain hose to the top of the dishwasher and then down to maintain the trap effect.

Pete,

Yep....know about that. What I plan on doing is running the drain into an undersink sump pump and lifting it into the main sewer line.

Another question - I will be draining the dishwasher into the tailpipe "tee" of my sink which will then empty into a lift pump. The pump is about 10-12' away from the sink. Should the air admittance valve go under the sink or should it be attached to the lift pump container? Tks!
