Package of 5 drink cups. Drinking cups require a source of water at a pressure below 5 lbs PSI which is provided by a pressure reducing valve, or by gravity tanks or buckets. These cups have a spring loaded trigger stem for positive shut off of water. Water flows only when the birds beak is in the cup. Designed to screw on #4087 and attached to a PVC pipe with low pressure water.

We are very happy with them and the birds caught on right away. No more dirty, poopy ground waterers that need daily refilling. These are easy to setup and super simple to maintain! (Posted on 2/28/2016)
Flashes out easy Review by Joey
If you have dirty or film water coming into the pipe it can make the cup leak. What happens is the particle gets caught in the valve of the cup. However , if this happens it is easy to fix. Just push theyellow nipple into the spring of the valve and it flushes right out. (Posted on 12/5/2015)
