MP3500 performance issue

Assuming you have the necessary pressure at the head, you may want to take the guts out of the head and turn that zone on. You should get a pretty good flow of water shooting out. I'm guessing you may have a small stone or something else blocking a fitting and not allowing enough pressure to pop it up.

None of my sprinkler stations are firing.

And the outcome was.................?

None of my sprinkler stations are firing.

Prior to your last post and changing out the controller, I was going to suggest disconnecting all the zone wires from the controller and testing each station terminal voltage with a solenoid hooked directly to the controller. (or use a voltage meter). That would probably have told you enough about the controller as to weather it should be changed. If the controller is operating as it should, then you have to look at the field wiring just as you suggested. Absent a good tracker, you will have to ...

No lightning strike, power surges that you know of ?? burn spots on controller? Either way you look at it, there should not be voltage to all stations at the same time. Does your meter show an "open" when you test ohms. What model controller do you have?

Also, test your resistance with the wires removed from the controller zone terminals for more accurate results.

I read your post as as saying that when you turn any zone on that you have voltage (27v+_) going to all stations terminals. If that is correct, your system will not operate properly because there is too much flow. Try leaving #1 station wire connected and disconnect the remaining station wires at the controller. See if #1 comes on ok. You can go through this process with all zones to verify each zones operation. It does appear you might have a bad board on the controller, but this will at least ...

master valve

Use a multi meter to test the resistance in the master valve circuit. Generally 20-60 ohms is good. do you have voltage at the master valve terminals at the controller?

Valve will not open, already replaced

Sounds like a blockage between the mainline piping that extends to the other zones and this particular valve manifold. To check. shut main water supply. take top off the valve in question. have someone open main water valve slowly. you should have a gush of water. If not, you have a blockage in the pipe that feeds this valve.

Issues with Hunter Sprinkler NODE400 - program cycles thru and never shuts off

You should have “one” start time on prog. A , that being 8:00 am. The 4 zones will then run in sequence for the set time of each one. Then it will shut off and come on again on it’s next scheduled day

Valve won't open manually, but opens when another valve does

Dat, Glad to hear you finally resolved it. Sometimes you have to step back and think of the smallest of things that were done previously And of which you believe had no bearing on the situation. That very often is the answer to the problem. Especially since some of which Described was not making hydraulic sense. (Valve not coming on manually). I figured there was some missing info as to why your problem existed. Anyway, glad you found it and just as important, thanks for getting back and letting...

Please, do let everyone who is following this thread know what the outcome is. We are curious to know

Valve won't open manually, but opens when another valve does

Don’t really see anything telling in the photos. Any chance somewhere along the way during a field repair zone #2 got connected to #4? I assume you checked voltage at controller terminals and made sure there is no voltage bleed from one zone terminal to another Disconnect #4 wire at controller and try #2 Checked resistance/ohms on all field wires ( none of this answers why you can not manually open #2.???)

See if you can resend your pictures in a different format. Was not able to open as originally sent. Have to think more about this

Valve won't open manually, but opens when another valve does

Not to be a pain, but please clarify your last statement as to operating the same via manual or controller. FYI, if the exhaust port in the valve body is blocked the valve will not open. But you stated that it works fine when it comes on with zone #4. So the bottom part should be fine. Two zones coming on at the same time could indicate the two zone wires are touching, but that doesn't answer why #2 will not open manually. Something is amiss here.

Valve won't open manually, but opens when another valve does

Ok, that kills my theory. It may be one of those where i'd have to see it to figure out. Something is missing in the information scenario. If a zone works hydraulically via the controller it should work hydraulically if manually opened with the bleed screw. Let us know if any new info pops up. Curious now as to what it is

Valve won't open manually, but opens when another valve does

So, when you opened #3 the water just went into the dirt/valve box. Just trying to wrap my head around what you have there. Things Are not making sense.

Just for jollies, open #3 manually and see what happens . That’s the one your not using yet
