I'm trying to figure out a little sprinkler system for my girlfriend's vegetable gardens. She has 3 small vegetable patches that run down a 60 ft length of fence in the back yard.

This is what I've come up with after an hour or so of searching the interwebs and yes I have no idea what I'm doing. Starting at the faucet I'll install a y-ball valve, then a hose end timer, then a hose vacuum break, inline filter ...
