Sorry, I’m traveling again. I’m absolutely happy that I switched from my indexing valve to in-line valves. There is so much more control over the system and u can now turn on any zone I want from anywhere.
Think about it this way. If you had different times setup for your zones and used a indexing valve, you could throw off the system if you did a manual run. And if you were traveling, you wouldn’t know which zone was selected.
Living in Fl, I like to water my garden anytime I want, and the in-line valves make it easy and reliable.
