OK, so I'm stalled out with my keggle conversions until my final and most important shipment arrives from Bobby. I just checked my cell and it is supposed to be delivered sometime this afternoon. To pass some time this afternoon, I went down to my local plumbing supply company and picked up drain/ejector pump system for my brewery sink. After discussing options with my plumber friend and doing some research, I decided to go with the Zoeller 105-0001 with the M53 pump. I checked out the "Drainosaur" by Little Giant and one by Stevens. Since the Zoeller is a little more compact, gets excellent reviews, and I could get a contractor discount, I went with it. I also decided to go with an air admittance valve for venting purposes, as I really don't need any more vents coming out of the back of my house.
I keep a box of plumbing pieces and parts laying around, but I am missing a couple of 2" fittings for the vent, so I really need to take a trip to the hardware. The problem is that the tracking on the package that I am receiving from Bobby today requires confirmation of delivery, so I have to sign for it. I'm stuck waiting for the USPS to arrive before I can proceed with either project.

Here are a few pics of my new pump system and the valve that I'm using.
