Due to small size of coop, I can't just drop a 5-gal bucket with 4 nipples on bottom. I attempted same bucket with pvc pipes but failed miserably due to leaks on the bottom of bucket (maybe I didn't drill correctly). Can someone help me a little bit? Idea is to have a 5-gal bucket (with lid) -- (at lower side near bottom or bottom itself) --> adapter --> valve (optional) --> pvc pipe or flexible hose --> another adapter --> pvc pipe with 2-4 nipples --> pvc pipe cap or something similar I read somewhere here but I lost it. I'll keep looking and will ask Home Depot in the mean time. Thanks for any help!
