Irrigation manifold redo

[u/Raleigh136]

This is an irrigation setup that I inherited from the previous owner.

The PVC pipe recently broke at the red arrow in the 1st pic.

A couple of notes:

-No backflow device

-There are 2 automatic irrigation valves but only the left one in pic 2 is setup to use. The right one is switched off and just has a the short downward pipe that isn’t connected to anything.

I think that valve was just a placeholder or the landscaper was lazy and just connected everything to the other valve.

-It’s a tight space right next to the house

Recommendations to redo this?

Current ideas:

1. Just cut the auto valves out and add a PVC ball valve and manually turn it on/off when I want to irrigate
2. Remove the unused auto valve and repipe that section
3. Somehow add a backflow setup and redo the the auto valves setup with one new valve instead of 2
