The Irrigation Reddit

Irrigation - the artificial application of water to the land or soil. It is used to assist in the growing of agricultural crops, maintenance of landscapes, and revegetation of disturbed soils in dry areas and during periods of inadequate rainfall. Additionally, irrigation also has a few other uses in crop production, which include protecting plants against frost, suppressing weed growth in grain fields and preventing soil consolidation. In contrast, agriculture that relies only on direct rainfall is referred to as rain-fed or dryland farming.

Irrigation systems are also used for dust suppression, disposal of sewage, and in mining. Irrigation is often studied together with drainage, which is the natural or artificial removal of surface and sub-surface water from a given area.

Irrigation has been a central feature of agriculture for over 5000 years, and was the basis of the economy and society of numerous societies, ranging from Asia to Arizona.

Switch from 4" pop-up to 8" pop-up without cutting pipe for new fitting?

Is there a way to switch from a 4" pop-up to an 8" pop-up without cutting the fitting off the supply pipe and glueing in a new one?

The sod in my yard is thick enough that the existing 4" heads don't pop up far enough to allow the spray to clear the grass. Is there a way to convert without cutting the fittings from the supply pipe and putting in new fittings that will accept the longer pop-ups with a side fitting?

Thanks.

Issues with 2-wire

I have searched for valves that the clock said the decoders were bad and replaced them and solenoids for good measure. The controller is a rainbird esp-xld. It still says it is in short finding mode and all irrigation is suspended. The decoder test returns with no results. When I try to ping individual decoders it doesn’t give any further information. What’s the next step? I need to fix this problem so I can winterize.

MPT to 1/2” poly

What is the best type of connector to connect 1” MPT to 1/2” poly line? The poly line is coming out of my valve assembly. From a maintenance standpoint I am thinking a barbed fitting with stainless hose clamp would be best?

Can anyone confirm that Rainbird DC solenoids always have black and red wires?

I'm pretty sure I've been given 24vac solenoids when I needed DC. Can anyone confirm that rainbird DC solenoids always have and red/black wires, plus say DC on the top? Been racking my brains why this setup has not been working. The solenoids I've been given are rainbird with all black wiring. Sorry the photos i've got are not close up enough. Cheers!

Can you cook a solenoid on 9vdc systems?

Made a stupid mistake wiring in some solenoids back to front. Some negative to negative some postive to positive. Controller is a Rainbird ESP-9V

Now with it correctly wired all the solenoids will click - though it sounds weak. But when I switch the water on they wont click or open the valves.

Have I just fried the solenoids? The controller seems to be operating fine?

(Edit: I'm wondering if they have given me 24VAC solenoids, valves are Rain Bird HV Valve W/Flow Bsp 25mm. Every other 9VDC solenoid I've used from rainburd had black and red wires.)

(Both the wires were black and I screwed the coil fully off, assumed the casing were in the same orientation- they weren't...)

Is a lot of 90 degree angles bad?

I have a situation where I need to connect another line of sprinklers to an existing zone. The issue I have is that I need to add a couple of 90 degree angles from the new sprinkler line to get it connected to the existing zone because of the way the existing pipes are situated. Will adding additional 90 degree angles reduce the water pressure to the new sprinkler line? Or am I too concerned about adding additional 90 degree angles (I always feel that running straight pipe lines offers the best pressure).

An alternative I am considering is to use 45 degree connectors to try to connect the new line to the existing zone. Does using 45 degree (softer) angles versus 90 degree angles help with pressure? Or does it not matter?

Thanks in advance.

Pretty clean install!

I ran across this manifold today and thought this was a nice install. Clean and easy to work on. The main shut-off is in the 4” pipe. Also, a nice hose bib for winterizing.

High School Irrigation Market Study

Hi everyone,

We're high schoolers trying to develop an engineering product to help improve soil moisture uncertainty in gardens and farms using drones. In order to develop an effective solution, it is important for us to understand multiple aspects of the market through data collection. We are hoping you can complete the survey provided below to provide us with information that will aid in the creation of an effective solution. It should be pretty quick, and would be greatly appreciated.

Total hours over a year on Rachio

Hello, has anyone found a way to estimate the total hours ran over the course of a year?

I need to know how many hours I ran my system this year, and haven't found an easy way to do it, other than manually looking at every event that occurred.

Thanks!

Hose Timers and Splitters

My lovely wife and I have been arguing over our hoses for the better part of a year and I am at my wits end. We have 2 main hose spigots with which we need to

  1. refill the watering trough of chickens
  2. refill the watering trough for horses
  3. have manual access to a hose that runs down to the barn
  4. manual access next to the spout

at hose 2 we need

  1. refill the pool on a timer

  2. water the garden

  3. sprinkler on a timer

  4. manual access next to the spout

We have tried the Eden Timers
https://a.co/d/hDfJME3 - they stopped working. Buttons stopped opening the valves.

We have tried the Bhyves
https://a.co/d/hDfJME3 - they are complicated, and leak horribly too.

We don't know what to do. We have enough actions that require timers that it feels like we need some level of automation. But everything leaks or breaks.

Does anyone have any brand / product recommendations to help us? I have included a drawing of our yard/ setup.

Thank you

Pressure test?

I have (3) of these valves assemblies that will be glued into a manifold. What is the best way to test this assembly before glue them together?

This must be the best way

The Premier lawn care company in my city installed my sprinkler system. My lawn becomes a swamp every year and it seems to be coming from around this sprinkler head. Definitely has to be a defect in the sprinkler head and not the installation, correct?

Converting from PVC to drip

I have a 6 raised bed plus a blackberry bush aisle I’d like to keep watered next season. They are as pictured. I dug and placed a 3/4 pvc pipe from the water spigot and the. Split them into 1/2 inch pipe leading to each bed except the blackberries and has a whole ball valve pvc drip system which worked pretty well this season. But I want to convert to drip. I’ll probably use rainbird starter kit since it’s easily accessible where I live. My question is if I want to connect my 1/2 in pvc is a compression fitting on each bed all I need? I have a psi limiter already.

Is there anything else I need to consider before converting over?

180 degree turn PVC

Is making a 180° turn with 1” schedule 40 PVC as simple as using using two 90° elbows? Is there anything special to do or consider?

Rainbird esp-me3 hates daylight savings

I changed the time and then the irrigation would go off at wrong times. I then changed the time back and now it won’t work—not even manual. I reset the panel and typed in my schedule and it won’t work run. Again I can’t even run manual. All wires intact. No power outages. I can turn dial and all appropriate things come up on the screen.

Help!!

I should have never touched it.
