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

(1) Coupler

(2) 90 deg elbows

(1) Tee

(1) End cap
