I have a whole house filter on my WVO pump, if its worm out i can filter the WVO out of the dumpster, into my 55 gal barrel in back of my truck. There is a by pass lever too so if its cold out i can just pump away. Once home i heat the oil in the 55 gal, and transfer off my truck to another 55 gal. "filtering it" . then from that 55gal to my holdiing tank "200gal" The whole house filters kits are like 45$ or so and the filters can be cheap if look around and catch them on sale,, buy by case in 5 to 20 micron size. i just allways use 5. /ubbthreads/images/graemlins/wink.gif
