I see there is some discussion regarding Netafim drip use, but it appears to mostly concern trees/shrubs.
I (and several others in my neighborhood here) installed Netafim subsurface for my grass areas. It would be really nice to have a “subsurface emitter” option for the type of watering in the zones so we don’t have to manually calculate flow rate.
Is anyone else using subsurface drip with turf?
(FWIW - we love it, 14 years with no issues, no worries with broken heads, wind, heads pointing the wrong direction, etc.)
By subsurface emitter option, do you mean to have that as an option in the zone setup process? After many years i find myself still skeptical of using sdi for turf irrigation. But that is just my bias in favor of spray irrigation. Rachio should add a drip option and allow a custom input of the gph.
I’m a contractor and I specialize in drip for turf. It works better than spray or rotary irrigation. I use it for both new and existing lawns. For a new lawn in summer, here in Austin, some supplemental over-the-top irrigation is required until there are some roots to water. I also install plant-specific emitter irrigation
There are loads of resources out there for people to convert gph to gpm and inches per hour and create a cystom nozzle as you wisely point out. However, i wish Rachio would add a drip option to the setup algorithms.
I live in NW Okc. I had netaphem 12" installed in existing flower, shrub, tree beds last Fall. But it doesn’t seem close enough to some of the plants and some have already died. I used over 3000 gallons of water in December just for the netaphem area about 500 sq ft. Can you help me how to set up a nozzle in the Rachio?
That is a problem with regular drip. The best answer is to convert to emitter irrigation whereby an emitter is installed at the base of every plant. That’s what we do. Perfect irrigation and you save another 25% of your water minimum.
We use a 17mm solid distribution tubing trunk line through the middle of the bed and we tee off with 1/4 poly tubing with an emitter to each plant. We anchor it with staples every several feet and every turn and install the emitter about 2 inches above the crown of the plant so we can see it.
Not in Oklahoma City. We dont want microsprinklers here. We use Netafim .4 or .6 gallon per hour with 12 inch spacing between emitters. The wetting pattern should be enough to provide excellent coverage. The problem is that Rachio does not have a drip setting. Consider putting the drip zone on a fixed schedule with a 60 minute run time. Ewing Irrigation has a good app to convert precipitation rate from gallons per hour to inches per hour.
