This valve can be used for a small system of 1 to 2 cups or a large system designed to support 1500 quail. Supplies 5 lb. water pressure to drink cups. Includes 5/16'' and 1/4'' hose barbs and 2ft normal pressure hose with connector. Place pressure reducing valve at least one foot above cups
Failed in less than a week.
Poorly built item that failed within one week and was not reducing pressure adequately (if at all) for cup waterers to operate correctly resulting in chickens being unable to drink. I noticed the reducer had failed because the pressure gauge had pegged out all the way to the back side of the needle stop permanently damaging the pressure gauge. Disassembled the unit and reseated the valve and spring, it worked for a day then went back to high pressure again. Glad it didn't fail when the weather was hot like it is now.
Would not work when I first got it had to take apart and free up valve
