Irrigation Trouble Shooting

Got a 13 zone system with poor pressure. The system was left on for 3 years, year round, never winterized. The stations come on, just really low pressure. By the time it gets to the back of the property, the RB 5004's look like someone taking a leak, sad.
Things I have done, not in order;
replaced MV, did not work
Checked water meter, backflow, no dice
Dug up main line, after Water meter but before and after MV to see if the line had been collapsed, nope
Check for leaks, one a lateral, repaired, still no go

What else can I diagnose, backflow?, proper voltage on controller?
Maybe a hidden regulator? ha ha
Any help would be great!!!!!
Thank You!!!!

Everything has a filter. Could they be clogged up?

Run a diagnostic analysis of the field wiring with your DMM, rule out electrical first since it's easy to do.

Now that you have done that, look at what is working and rule that or those out.

How did you rule the meter and backflow out?

Seems that whenever multiple valves aren't working well you can usually turn the water off and pull the bonnet and guts out of the nearest valve to the source and flush it. The meter should be screaming if there's no obstruction. Focus from the first valve to the meter.

Oh yea, never rule out a hidden anything.

Compare what the zone is designed for, IE four 1.5 5004 =6gpm, to what the meter moves when that zone is running. System left on for consecutive seasons in a freezing climate? Could be a leak not surfacing.

electrical is next. no water coming out of any heads when system is running.

Some of the filters on the heads do have a bit of trash. Flushing is going to be needed.

Wasn't my deal then. The previous people where charging the customers for services not performed. Was told by a tenant that about 4 years ago they called the landlord about the system running on a 15 degree day, ice everywhere. I will check the nozzles and heads for that. Getting accustomed to this with this installer, I don't know if they are even in business anymore.

Thank You Everyone. I will update.

This takes some investigating. I had the exact same problem just a few weeks ago and after checking the irrigation system, electrically and hydraulically, all components were working. Now I had to start asking a lot of questions and come to find out the irrigation system was running through a water softener and I proved it to the home owner by shutting off the water softener and up came all the heads.

I am looking at three possible problems. This being a commercial property,
a water softener is out. I did rule out leaks. I left the MV open and checked the whole property. Nothing. We are pretty dry here so I would see one if there was one.

But did you check the meter? Was there any movement at all when th MV was opened? Walking the site is a waste of time if you are on a meter.
