I installed my irrigation system about 3 years ago. Ever since installing it, I have one zone that causes the ASV to rattle pretty loud. All other 4 zones are totally quiet when running. I've replaced the valve, flushed the system, checked for leaks and I just can't seem to figure out what in this zone would cause the rattling. Irrigation is after our PRV which is set at 70psi. All spray bodies are Rainbird SAM PRS 30 (check valve/pressure regulated at 30psi) with Toro Precision spray nozzles. There are 6 heads in this zone.
My understanding is that this is usually a sign of a high flow situation, but I've walked where the lines are and I haven't notice any significantly soft/mushy areas so I struggle to think it's leak related.
Any suggestions on additional steps I can take to troubleshoot this? Thank you!
