Tarev, I have done something similar for my mobile home lot. The pvc over the rebar also prevents damage when string trimming around them. Ask me how I know. I have used the dual spigots for many years, as I only have 1 spigot and it requires a 100' hose to reach all the way around. To solve the problem, I ran pvc , complete with spigots to each flowerbed and use short hoses to connect that to the main spigot. I have soaker hosed in each bed and control them from those spigots. The only problem is that those " Y" or Quads are cheaply made, and the valves don't last very long, at least not here, and you do need a backflow preventer at the main source. Still well worth the effort and pvc is cheap and easy to work with.
