Cast aluminum, blue, non-porous 7"L x 5 1/2"W x 1 1/2"D for watering all swine. Uses a trouble free, non-siphoning patented 393 valve. Stainless steel trip plate is pressured by swine to fill cup. Orifice sleeve inside the filter controls high & low water pressure for uniform water flow. Holds up to 2 cups. (3 lbs*)
The tank is a food grade 55 gallon plastic barrel
the bowl is the system used to water horses. (Pic attached)
I just drill a hole into the drum the size of the pipe coming from the water bowl and also two hole for the mounting bolts. I set he flow adjuster to full because the only pressure is gravity so the water flows correctly.
i mount the bowl at the very bottom of the drum so the bottom of the bowl pests on the pallet. This way the hog doesn't break the bowl if he steps on it. I also put auto gasket cement on the washers inside and out side of the drum whew I have drilled the holes for mounting and flow.
It takes about 1-1/2 hour to make and costs about
$35.00 including barrel, gasket cement,washers,and the bowl itself.
