Is anyone else constantly battling weird issues with their DIY sprinkler setup? I finally got mine installed last spring and thought I was in the clear, but it seems like every month there's a new problem cropping up. Right now, I'm dealing with really uneven water pressure across different zones. The first two heads barely trickle,while the last one in the series is practically a geyser.

I've checked for obvious blockages, made sure all the heads are clear of debris, and even tried adjusting the flow at the manifold, but no luck. I'm wondering if maybe I undersized the main supply line or if the cheap zone valve I bought is already crapping out. It’s a 3/4" line feeding four zones.Anyone have experience with something similar? any tips before I start tearing things apart and potentially flooding my yard? I'm starting to think hiring a professional would have been cheaper in the long run!
