I wanted to keep my chicken coop off the grid as much as possible so I started with the watering system.
I needed save space so I thought a trough waterer would work well.
Step 1: PVC Rain Barrel
I created the rain barrel out of a 4 ft section of 8 inch PVC pipe I got from a local contractor. I used an end cap and sealed it with 5200 marine adhesive. Then I installed 2 3/8" MIP hose barbs and coated the joint with more 5200. The one on the top is the inlet and the one at the bottom is the outlet. The inlet was installed as high as possible based on the gutter collection point.
I also installed a chain to keep the barrel from falling over when full.
NOTE: Use the fast curing 5200 marine adhesive. The normal stuff takes a full week to cure and waiting gets really old!
Step 2: Gutter Connection
To collect water from the gutter down spout I glued a short section of the down spout material inside the to[ elbow to create a little weir. The water is redirected into the PVC pipe coming out from the left. It runs into the coop and through a third 3/8" hose barge and into a hose connected to the rain barrel inlet.
I also included an overflow leg by using a tee and a 90 deg elbow so I can see if the system if full. If the system is full or its raining so hard that the rain barrel can't keep up, the excess water flows over the weir and down the gutter like it normally would.
I used the following 3/4" PVC parts:
(5) Short sections of 3/4" PVC
(2) 90 deg elbows
(1) End cap
