I needed a clean/efficient water delivery system with out taking up space in a compact coop. By leveraging "water nipples" bought online for $5 for a dozen I built a system for about $15.
Step 1: Drill 1" Hole for Garden Hose Attachment & Vinyl Hose.
Drill 1" hole for hose attachment & goose neck valve. I used a rubber hose washer to avoid leaking, no sealant needed. After attached, move on to connecting the 3/4" vinyl hose w/ hose clamp.
Step 2: Attach Water Nipples & Distribution Pipe.
Drill holes for each nipple, I have 4 birds so inherently 4 nipples. I did use plumbers tape in addition to silicone caulk.
The piping used is plastic designed for outdoor sprinkler system. I am sure pvc would be fine but I preferred the grey look.
Screw on threaded end cap and elbow. One side of the elbow is threaded, the other ribbed - designed for hose attachment. Again used a hose clamp for added security.
Step 3: Elevate Bucket and Attach Distribution Line.
The bucket exit valve should be elevated above the distribution line to allow for gravity to fill. I placed behind the chicken coop for easy access but also positioned to be out of sight.
I leveraged old stones from a previous project.
Attach the distribution line to the birds natural head height (no extension/bending). I attached directly to the chicken wire with zip ties.
