I used 1" pvc, but when I redo the system, I will be using 2"...I found through experimenting with the drill, 2" pipe is easier. Other than that, it is just a pipe with the nipples in place connected to a bucket. The end cap is for draining it in the winter. If you do connect it to a hose for a constant supply, you will have to reduce the pressure with a pressure reducer, or they will leak.
