Does this work with drip irragtion

not sure, trying to figure this out

Yea I’ve got some drip emitters in our garden area and you just put in the precip rate and the area’s and all works to plan.

It definitely works, but if you’re like me you’ll find it’s challenging when you try to convert GPH to in/hr. This link might help.

Drip Emitter Calculator for Precipitation Rate & Area

I put together a calculator for precipitation rate (PR) and area of emitter systems that do not have continuos, evenly spaced emitters. The calculator is complete, and includes the link to the Web Soil Survey instructions as well. The calculator is easy to use, but please read the notes above the calculator to be sure you give it the right data. The information below the calculator is just a description of the equations involved, so ignore that part of you don't care for the details. Please…

Yeah, there’s no problem with using Rachio and drip irrigation. Just make sure you set the zone attributes up as close as possible to the drip system specs.

For what it’s worth, I caution against the use of the ‘Precipitation rate calculator’ above. It assumes an area of 1 sq.ft. for each drip emitter and I leads to under-watering your vegetation. I tried using that method and it was frustratingly wrong. It’s actually the reason that I created the drip calculator I posted above.

No offense to anyone, but there have been a lot of people that have had a lot of issues with setting up drip due to the 1 sq.ft. assumption.

@azdavidr Thank you for the feedback! I’ll make sure we look into this further.

There’s a long sordid history. Some of it can be found in the thread where the calculator was being developed. Other threads have people that tried the link you mentioned and they ended up having problems.

Three years and still no Gallons per Hour?

@redwagon If you use the 1 sq. ft. assumption, do a sanity check on your run times once you use the associated PR. I found the watering duration to be vastly lower than what it should be using the 1 sq. ft. assumption for single point emitters. I know the 1 sq. ft. assumptions work for some. Maybe it’s due to desert watering requirements, but I would check your watering times against what you expect them to be. My PR for my 2 GPH drips (3 per tree) is 0.4 in/hr to get the deep watering we re…
