Grey water pumps look like they are about $150, which is far, far too much. I'm looking at a small stainless sink w/faucet on craigslist for $20. If I can mount that high enough to gravity into the drain I'll be good. All I really need is hot/cold water and somewhere to dump chems. Actually, before I found out I had laundry hookups, I was planning on just hauling water to/from the bathroom across the apartment. Just having closer water and somewhere to dump chemicals will be great.
