Sprinkler system repair and questions

Repaired. Plugged for now until I go get a new head or manifold.

Have you been having trouble finding leaks with how wet it's been? We have a dozen or so spots that we've been trying to figure out if they're leaks or just ground water all season. We've also only had to water a handful of times though. Although we definitely knew when we had a whole head pop off a swing arm and shoot a geyser 20 feet into the air directly in front of the clubhouse. 150 psi is a lot of pressure.

I think the fescue should come in fine, although it might be getting too hot. Definitely update if it does germinate.

Pressure decreases suddenly then I walk around and notice puddling water 😂 so not too difficult to find. Groundwater should be much deeper for you up in Evergreen. I should put meter on and see what pressure is, I know at the spigots it's 70 psi

True, I forget that a backyard is a little smaller than a golf course. I haven't had a residential sprinkler system in forever. No point in watering the side of a mountain. We have a few weird spots that have turned into swamps this season plus a few springs we've had for a while. We had an entire fairway in the creek last week. Even got a new log.

Is the irrigation system the last big project left on the house?

You are measuring what is called 'static' water pressure. In this scenario, it doesn't mean anything. Go to your local Rainbird or Toro dealership and borrow a 'dynamic' pressure/flow gauge. It measures the pressure when the water is flowing and how much flow rate your system can provide. They also have design guides to show you how to divide your system into zones, so you will have enough water pressure and flow to properly operate the sprinklers in each zone. Good luck!

Zones are the way to go. Not everything needs watered all the time. I thought most residential systems at least kinda had zones already but it's been a long time since I've done anything with residential systems.
 
Zones 1 (yellow) and 2 (blue) are turning on simultaneously. Why? All other zones (3-6) work as they should.

They're big sprinklers, so they need quite a bit of pressure to turn on and if they're on at the same time I obviously cannot get pressure.
 
Thanks guys.

I've got a couple of issues, though at this point I can run everything with the controller in the garage.

I think the valves and solenoids need replaced. They're original (however old that is).

It almost sounds like something was wired wrong somewhere. Do both run when zone 1 is turned on and then just zone 2 runs when it's turned on or vice versa?

When zone 1 is turned on, zone 1 and 2 come on. When zone 2 is turned on, zone 1 and 2 come on.

I've verified they're wired separately.

Yeah sorry if I'm just saying things you've already verified or thought about. I don't know if I'm being helpful or not. Just trying to do the process I'd go through in my head if I was working on it in person.

It helps! Could be something obvious that I just can't see. I'm stepping away from it today.

Just wanted to make sure! It's very helpful for me too. Residential sprinklers have the same basic operation as the type we use in a golf course, but are honestly a little trickier to figure out. We just have 1 common wire going to a valve in each head and can turn on individual heads and the system is always pressurized.
 
So the inline valve isn't opening fully. It opens enough to have the backyard work, but soon as the front is turned on I have to manually open the inline valve about a 1/4 turn as well as the Zone 1 valve itself, then everything up front goes full force. Maybe in a week or so I will get it changed.

The wiring is still wonky, so the valves for Zone 1 and 2 will be replaced also. That should help.

The back yard is looking better! I still need to fill and seed a few areas but will do that come fall as it is a cool season grass.

Your dog seems to agree...

Soil temps have been staying in a surprisingly good zone for cold weather grass, up here at least. Forgot to take a picture, but I was seeding and sanding tee boxes last Thursday and had a bit left over in a closed tub. When I opened it today the grass had already grown 3 or 4 inches completely in the dark. Plants are rad.
