I wanted to build a simple, adaptable irrigation setup for my four new raised beds. It is probably not perfect, but in my initial tests this seemed to work as needed. I will also be able to add a timer to the system easily since I had enough water pressure and volume to run all four beds at once.
I've never posted stuff like this before but I do stuff like this all the time. If you have questions or comments I will be happy to try to answer.
