you have any good links for this Cold Up-Flow settling method?
There are a number of people doing Cold Up-Flow Settling, but John Galt seems to be the go-to-guy for Cold Up-Flow Settling.
I went one step further and installed a dip tube in my filter barrel so the pump draws oil from about 6" from the bottom, giving even more opportunity for settling.

i settle untill the oil has cooled from 150* down to about 100 which takes 48 hours in the summer and 24 hours in winter.
A tank will settle out in less time but i have to wait for it to cool.
i just started using this method as with my new source i have to collect in a drum outside. im taking water precautions even though after my first collection a hot pan test showed no water. but one cant be too careful.

I've pulled so much water that it's not even funny. I sometimes boil it out and end up with 2/3 oil and the rest evaporates.

Clay, I have a 250 gal plastic tank outside that I pump thru the shop wall where I have household water filter housings mounted up that dump into a plastic 55 gal drum with a spiket on the bottom. prior endevor. I purchased a 50 gallon electric hwh and a couple northern pumps like you recommended. one for backup. would there be anything wrong with plumbing " your" setup in schedule 40 pvc? My plans are to filter to 5 micron before hwh. overkill maybe. then go thru another set of household water filters w/ 5 and then 2micron after hwh while oil is still warm. Why do you wait til the oil is 100 degrees before moving? safety? thoughts? thanks, Scott

PVC would work well i believe, in fact i want to redo my unit because these hoses get old and hard and i have replaced them twice so PVC might be my next choice.
I settle the oil till it gets down to 100* because it is settling out particle matter and water while its cooling. This is the most effective, least expensive (free) way to clean the oil. Take a sample quart jar of oil, mix in some corn meal and a little water, shake it up. You will have an emulsion when your done. Heat the sample on the stove top till it reaches 150* and then remove the heat. See how long it takes till you see a visible layer of water and particle matter in the bottom of the jar. This will demonstrate the settling process in the HRH. So skip all that filtering your talking about and let gravity and heat do the work for you. Oh and water filters are not recommended.

Clay, have you updated your setup in the last 6 months or so? Changed anything? Just trying to get caught back up in the WVO scene... I originally copied my setup off of your frybrid still deal, and figured you'd be a good source to ask about updates haha.

If you are going to use PVC pipe, I would suggest using CPVC pipe( you know, the gold stuff), it's a little more durable, (a little bit more expensive too, not too bad tho) and is rated for hot water use. I don't know anything about WVO systems, but I was reading the post about PVC, just thought i'd offer my plumbing opinion :thumb:

Haven't changed a thing... Yet. I just ordered an absolute centrifuge and am going to completely change my filtration methods. Not for any reason other than I like to tinker. The "still" has worked flawless for almost 4 years but I really want to try this centrifuge setup. There's a link here somewhere and I'll find it for u if interested.

Ok cool. I'm glad to hear you liked your original setup though. I agree tinkering is always fun, but I would really like to just use my system and try it out for a while. I'm sure once I have the setup working like clock work, I'll want to change it too, keep things interesting.

Thanks for the link, I'm gonna start researching centrifuges now...

How does one heating element in the bottom of the HWH heat the all the oil to the same temp? ) I would assume that the oil in the bottom of the HWH would be a much different temp then what's at the top. Or does it matter?

heat rises and oil conducts heat very well.

Suggestions: start saving money if your blending fuel. Soon you will be buying a new engine.

Yet I've been doing it for 4.5 years in the same two vehicles without any issues what so ever. Maybe I'm on borrowed time and I'm sure living in Florida's warm climate helps, but I'll stick with what I'm doing.

FL warm weather is definately a plus...kinda like smoking light cigaretts instead of Marlboro reds though...What % is your blend? How many miles have you gotten by with doing it...years is irrelevent, some people drive 5k miles a yearr, while others drive 50k miles a year. If you have been doing this for 200k miles then you MAY have saved enough in fuel to pay for a new shortblock but I doubt it.
