I have had Rachio for a couple seasons now and my lawn always seems to dry out, can someone help me figure out the settings? I just raised the Available Water setting to .2 in hopes that will help?
I am located in New Jersey - here are settings for one of my zones:
Have you done a catch cup test to make sure your nozzles are really putting out 2 inches per hour? There’s a chance they are not actually putting that much out, but Rachio will think it’s been getting enough water.
Hey, thank you for your quick reply!
I have not - how would I go about doing that? Where does the cup get placed and what size cup should it be?
Here’s an article on it. https://support.rachio.com/hc/en-us/articles/115010542208-How-do-I-perform-a-catch-cup-test-
You can use cans like tuna cans, but I just went ahead and bought some Orbit catch cups on Amazon. More expensive but they will get the job done right.
Hey @Linn - thank you for that great information! I bought Orbit Catch Cups and just finished running my test, most of my zones came out to only 0.36 in/hr!
I calculated it using this website: https://sprinklersystemcalculator.com/audit.html
Now that I adjusted it though, I see something else that seems off - my schedule for tomorrow is now showing around 2 hours of water time for each zones, that’s excessive…
Does this seem right to you? Here are the settings for one of my zones.
Thanks for all the help!
Actually, I just reset each zone to default since I had been messing with the settings, then I readjusted the inches per hour.
Available water was reduced to 0.17 from 0.20. This dropped the amount of water time to 1 hour 45 minutes per zone, but that still seems like a lot?
It is currently showing a 71% Soil Moisture.
If the 0.35 in/hr seems low to you, you may want to double check the catch cup procedure. But if you’re certain of the result, then yes, at 0.35 in/hr the 1 hour and 45 minute watering times would be reasonable. At 0.35 in/hr, it is no wonder that your lawns dried out with the previous 2 in/hr setting.
@Kubisuro I believe I did it all correct, and also got the same amount in most of my zones.
I put the Orbit Catch Cups all over the zone area.
Ran the zone for 20 minutes.
I kept track of ML in each cup, so used this site to calculate the total https://sprinklersystemcalculator.com/audit.html
One example zone had these amounts (in mL)
When I use that website and enter 16.25 throat area, 20 minutes, and all those mL amounts, it says 0.35 inches per hour.
I am assuming the website is calculating correctly?
It just seems strange, my lawn does look very wet after running for only 20 minutes, but I don’t know enough about watering lawns to understand how much water they really need.
Great, I will keep an eye on it and update you. Thank you all for your help!
