the nutrient valve pipe is rendering on top of the wheel that you spin to open/close it
I've tried
-un-placing the entire pipe network and placing it down again
-placing the pipes in various orders
-placing then reloading
-un-placing, reloading, placing again

I got it to work exactly one time and i dont know what i did to make that happen

I dont have an error log cause it doesnt give me an error when placing even in dev mode
Not sure how to link my mod list, i have it in a text file i got using rimpy, but it doesnt look like i can upload files
