Trying to water 4 quail cages. Planning to use 3/4"pvc, nipples, and a 5 gallon bucket. The "closed" end of the line will have a stop valve so I can open it to flush the system. I will fill the bucket manually (with a hose) every few days. My question is: can I pipe the pvc directly into the bottom side of the bucket or do I need more height? Also, do I need a lid or just a screen over the bucket? Will it even work??
