I guess one downside of my layout (if you consider it a downside) is that all the black tubing and occasional Tees and crosses do look a little geeky. Like THAT could be a bad thing!
I learned last spring that hard freezes do not
necessarily burst tubing, fittings and timers. I didn't drain my system at all well, yet NOTHING burst or sprang a leak! I think I got lucky.
P.S. If you have trouble stooping and squatting like I do, it's worth while propping up the frequently-used valves and things like timers on a cinder block or stack of bricks so you can reach them without grunting and groaning.
