WVO Collection. Ugh.

I have never completely found a good solution for this.

I find that oil generally comes in two ways, either in the 5 gallon carboys, or else in a dumpster, with 20-200 gallons. So you need a pump system as well as way of dealing with carboys. I used to dump the carboys into settling tanks and then pump from the tank to my drity tank. That doesn't work much when I'm on the road, so I gave it up. I came up with a better solution below.

As far as pumping large quantities into the tank, I haven't found a perfect solution. I first attempted an air pump, which was incredible when my air tanks were loaded up, or at least was incredible for the first 10 gallons or so, then I needed to wait for the air compressor to catch up. I was using the bus air tanks combined with a large air compressor, and it just wasn't enough.

After that I tried the normal solution of an electric pump. That was slow but steady, until it died in 2011, right after finding about 80 gallons of oil. Heartbreaking.

I think a trash pump is the way to go - and I bought a mini trash pump on ebay, but unfortunately it is very, very, very hard to prime, so I haven't really used it yet. Need to plumb it properly and prime it. Unfortunately it's also chinese made, so I doubt it'll last long.
