Thanks fellas!! I'm really leaning towards the Wolverine products; I like to support our "local" vendors, and I've heard nothing but good things about their products.
I find I need to use a settling tank because of some of the suspect WMO I've been getting from friends & neighbors...some folks like to place their UMO into used 5-gallon paint buckets, which tries to dissolve the latex paint & create a nasty sludge. Filter socks have worked pretty well at filtering out these solids, but I still get a LOT of water & antifreeze contamination in my free WMO supply. To be on the safe side, I'll incorporate a settling tank.
For now I've been coarse-filtering my WMO supplies into 55-gallon drums that I've been getting free from a friend; they originally contained engine coolant so I flush them out with a gallon of brake cleaner and let them vent out for about a week to dry (it's a VERY dry climate here, sometimes it works in our favor!). If they need additional flushing, I do it then, but it's hard to beat free!!
Thank you again to everyone for your excellent help, tips, and pointers!! This really helps to figure out what I'll need to set up once I get my concrete poured for my Deuce parking pad that will also act as a refueling & WMO-filtering station.
