Report of issue with Master valve

I would really like to get this resolved. Going to have to replace the Rachio at this point since it will not run a Pump Start Relay without erroring out every other time!

Hey @dirkg - having the team review now. So sorry for the delay!

Hey @dirkg, I sincerely apologize again for the delay in response, I’ve been away from the office on leave. I was actually working in our DMs to address the issue and let you know we were actively still investigating your particular PR model. We believe the issue stems from your pump relay’s inrush current.

In the meantime, I would like to clarify and confirm that your current setup is not actually interfering with watering, but is generating “false” errors every time you trigger a run. I do see your system currently running along with several past history events indicating that it has actually watered.

I still see that you have notifications for the alerts still enabled and would like to refer to my original suggestion to disable the notifications:

This should at least silence the problem until we are able to confirm the root cause.

@dirkg, do you happen to know if there’s any additional numbers for your PSR model number? I’d like to cross reference the tech specs for your PSR to better understand it’s power requirements. If you’re unsure, feel free to post a photo of the PSR. Additionally, do you know what size pump you’re running (in HP)?

This is the PSR:

I believe my pump is 1.25hp. I’ll verify when I get home.

Fair point, although i cannot really tell if it has an impact on watering. After the alert there have been times (not always) when I cannot get the system to respond. It may be some plaguing WiFi issues or related to the Master Valve error. I will be more diligent about noting the operation (normal or otherwise) after the next Valve Error.

Thanks @dirkg! I would not assume that your experience with the app sometimes not responding is directly related to these error notifications. There could be many factors involved including your controller or device’s signal strength.

I’d definitely recommend ensuring you are on the latest version of the app via your device’s App Store. If you continue to experience unresponsiveness afterwards, it might be best to open a separate investigation with our Support Team!

My guess is the Rachio Controller is overly sensetive to the induction current from coil. If I have time this weekend I will put in a diode and see if that eliminates the false readings.

@dirkg - out of curiosity, how close is the PSR to the Rachio controller?

About 20feet of direct burial 18ga connects them.

@dirkg - that answers the question. When I saw the mention of induction current I was wondering if they were side by side. 20’ should be far enough.

So I mainly just use manual runs at this point and the Master Valve issue is worse that ever. The PSR kicks in then immediately shuts off. Sometimes if I try the manual run several times in a row it will eventually work. Sometimes I need to reboot the controller. Sometimes I just give up and try again tomorrow.
Can someone please look into the logs of my controller over the last few days and see what is up. If it is a sensitivity issue to induction voltage, please address in software.


I’m no help here, but I know who is!

Hey @dirkg! (Thanks for the heads up @tmcgahey :slight_smile: )

I had my team take a look at the logs and it looks like the issue is coming from zone 8 specifically - would you be up for looking into that zone to see if there’s anything weird happening on your end?

I’m also having the team look into the firmware side of things to see if there’s anything there that could be affecting this.

Let’s keep each other posted!

:cheers: Lo

Thanks for looking into this. FYI I have seen it happen on zone 1 in the past…but any way…Zone 1 is a Hunter PVG101 with three pop up rotors. The Master Valve is tied to my PSR to energize the well pump. I do not have a pressure tank. Are you guys looking for load or resistance on the Zone 8 terminal during operation? That could be an issue as this is not connected to a valve. It only turns the pump on for when I have the hose bib open. Still trying to figure out if the anomaly you are alerting on is from the Master Valve or the zone terminals. Induction voltage from the PSR or no load on Zone 8?

RACHIO>Master Valve Wire>PSR>220Volt RELAY>WELL PUMP>Hose BIB(normally closed)>Manifold
RACHIO>Zone 1 Wire>PVG>3 Rotor Heads
RACHIO>Zone 8 Used When Hose Bib is open (nothing connected to zone 8 terminals) I run zone 8 to force the PSR on only.

Hi @dirkg,

Zone faults are triggered when we receive more than 1.5 Amps through the power supply.

It looks like you may already have a relay setup for the things after the master valve. It may be the master valve itself, but if you think the master valve isn’t triggering the zone faults the next steps would be, like you mentioned, to try to isolate the individual components and see if any one of them draw more than 1.5 Amps at any time they are triggered, especially during start-up of the zone.

So Im digging around the forum and I see that this issue is already documented in the thread: Rachio 3 Pump Start Function by CROCKBOY. I am using the same PSR. Your answer to hime was to get a new PSR…is that what’s going on?

The regular Munro PSR required more power to switch on my irrigation pump than the Rachio 3 supplies. Munro makes a PSR with a special circuit that reduces the power needed. The new PSR works perfectly

If you are using the same PSR originally, I would recommend purchasing the same/similar one referenced in the other article since that seems to be the root cause.
