Title: "Duo" waters only one valve
Review: I object to that fact tha this exists. The very name implies a dual-valve watering system. It looks like other dual valve systems. But it only waters one valve. The other valve? It's a handy "manual watering valve". If I wanted a manual valve I'd get a $3.50 brass T-adapter!I boutht melnor's other non-computer two valve waterer recently, but it leaked so I returned it and bought this. Needless to say, I'm not trying melnor again!
