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.

Help Identifying a sprinkler valve

Does anyone have any idea what model this is ? I likely have a faulty Solenoid, but would like to replace the valve internals as well. Any help would be appreciated. It is likely from the late 90s or early 2000s.

Thank you

Small leak and steam coming out of the top

I was going to blow this out today. It’s unseasonably warm in the northeast I might have even pushed it a week or so. Noticed it leaking and I don’t know from where and even more weird is there appears to be steam coming from the top. Why would this happen??

Underground drip

I know what I am about to say sounds crazy, but … I have a driveway which has narrow pieces of land on both sides. I plan on planting clover/grass mix and also small trees. As time goes by, maybe I will add other plants too. For this reason, I don’t want to put in sprinklers. So I thought of underground drip tube. But underground means I would not have access to it easily, in case it gets cloged. Plus, I am afraid I would cut it while planting. I have a few drip tubes around my vegetable garden that I placed directly on the grass, to get from one part of the garden to the other. And I noticed they get covered in time with the grass (if it’s rainy, in just a few weeks), enough that they are not visible, unless you are looking for them. The garden robot has no problems in cutting the grass over and around them. So I thougt why not try this with an underground drip tube, placed in a grid over the grass, that I would have easy access to, and that is made so that dirt can’t get in easily. The roots would not try to get it, as the tube would be above, I could water the grass and the trees and the other plants. I could easily replace it if necessary. It would be more accessible, more efficient and it wouldn’t need that much pressure. But I’m sure you will tell me why it’s not a good idea :)

This is a pic I took today where the diagonal is one of the drip tube I was talking about.

Do I need a back flow preventer if my valves are anti-siphon?

I'm planning a sprinkler system for my home in Florida to cover about 700 sq ft of grass in one zone and a 100-foot soaker hose in another. I'm considering using the Rain Bird 075ASVF 3/4 in. Plastic Residential Anti-Siphon Irrigation Valve with Flow Control, with one valve for each zone. These valves would be installed about 14 inches above the highest sprinkler head.

Since these valves have built-in anti-siphon features, do I still need a backflow preventer? If a backflow preventer is recommended, what would you suggest pairing with these valves?

Any advice on changing out this handle?

I’ve got a ball-valve going from the city main to underground sprinklers that is about 3ft down and I need to replace the valve handle. I would prefer not to dig out the whole thing to get access, and i dont really want to replace the whole ball valve if I don’t need to. Right now my plan is to spray a bunch of penetrating oil on it, then use a super long ratchet extension to remove the nut, then a grabber tool to replace the handle. However I also feel like that may be a really stupid plan so I would appreciate any suggestions. Thanks in advance.

Mystery leak

Curious if you guys have customers where you can’t find the leak. Meters spinning when it shouldn’t. (Separate meter)Can find no visible signs of leaks but they get calls from city about higher water use. I’ve fixed alot of stuff for this guy. Just don’t know how to locate a mystery leak.

Upgrading Rain Bird ESP Modular to ESP-ME3

Hi folks. I'm trying to upgrade my old ESP-Modular to a Rain Bird ESP-ME3. I have the face plate and LNK module, but the pin configuration on the ribbon is different so I understand that I need a new backplane. I think it is the one here that is marked "Assy 639660": https://www.ebay.com/itm/285540350589?_skw=Assy+639660+rain+bird+backplane&itmmeta=01JC1KYWVCJCB66DKZDY78VEY4&hash=item427b87fa7d:g:cs4AAOSwQbllQkey&itmprp=enc%3AAQAJAAAA4HoV3kP08IDx%2BKZ9MfhVJKlNfPOS10Q912tyGOcZx%2FjRoyxjgU45wNv7SHcFjKVNGkMN7s%2BjfC%2BlWrQlJ6crldlVZJa0nlLS1Yz9ISCqs2uwfUbXT4OEO9OChUaqYrzQJ2QJ%2FbAq%2FfXKWbAMSyBDSncST78UTE5VV2LWgU6RqbIQMVRgPZF7oQJNbkvqRGGRyzIaku2HZ9UDKb0NACk1HTP%2ByvEvuxYuOe30ZJBXzWFqyPHuxPq%2FEzWDWcFllPrmgCwMd%2BiKawrp%2BI7rPxnpAUR9oaFbXzaI23IxIVRVGjzi%7Ctkp%3ABk9SR9zN-7PgZA

Does anyone know where I can buy just the backplane? Google is not helping. Thanks!!

Does this shut off valve require relief valve ?

I was told by irrigation system folks that I need a valve on the this shut off valve so the water doesn’t linger in the pipes outside the house during winter. He had to blow the sprinkler system/heads and he looked at this shut off valve and called out. Any suggestions here ? Thanks

Pressure at heads

I’m looking to put a PRV on my irrigation system. My worry is that going from 115psi to around 70 psi is going to cause issues with the distance water is dispersed/thrown at my rotors. Any thoughts on this? I was really looking at the PRV to avoid damaging the heads but maybe I’m overthinking this.

Splice irrigation wires together while keeping separate zones?

Hi, is it possible to keep my zone 1 wire and zone 2 wire separate but somehow splice them together to zone 3?

Reason is that sometimes I want to run both zones at the same time but sometimes I want to run it separate. This is a rachio system.

My thought is that it isn't possible because if they are spliced, one zone will always activate the other zone?

Thanks in advance.

Help identify sprinkler irrigation controller

I have a new to me home. It has a four-zone sprinkler system. The first zone, zone one, isn't correctly working.

Zone 1 turns on if the main water valve to the sprinkler system is turned on. Said differently, without enabling Zone 1, Zone 1 will still run if the main water valve is on.

Can I replace just the 'top' portion of the valve without redoing the piping? If so, what replacement valve should I order?

Thanks so much!

Cement recommendations

I have rather high pressure water (110 psi) and am putting in a PRV. Will standard Oatey PVC cement (with primer) be sufficient or do I need something else?

What are your favorite electric irrigation controller features?

  • Connectivity (only wifi, wifi and bluetooth, cellular etc.),
  • smart irrigation capabilities (adjust daily program),
  • sensor support (flowmeter etc.),
  • display type (touch, character + button + dial, character + button)

In addition to these, what else would you like to add?

Orbit B-Hyve timing is wrong after DST?

Hey guys, is there a setting in the app that allows you to set the time manually or select DST? Currently my controller is spazzing out. For example, I have it set to go off at 4PM, it will go off at 3PM since the our just changed. While this wouldn't be a big problem normally, sometimes it doesn't show that it's currently watering and instead it'll show that it's going to water in an hours time meaning that if I needed to cancel the watering, I wouldn't be able to. The calendar is also reporting wrong details as well because of this.

Manual or auto drain

Hey all! First time homeowner doing his best to winterize. I don’t own an air compressor so I was wondering if someone could look over the actions I took 🙏

For outdoor spigots:

  • turned off main water supply
  • opened outdoor spigots until drained
  • closed outdoor spigots

Note: I have frost free spigots and couldn’t find an indoor valve specifically for the outdoor spigots

For sprinklers:

  • turned off main water supply
  • used water meter key to turn off irrigation
  • turned irrigation control box program to off
  • I’m not sure how to drain with my valve box (pictured). Could I get some help here?

pressure reducing valve

I need to install a PRV as my water pressure at the back flow is around 115 psi. I live at the bottom of a hill. Now that it is winterized I think it's a good time to do it. I assume it is best to put it in before the back flow valve and in an area very accessible. I was going to put it in my basement after the main shutoff to the irrigation system but before the back flow valve. Any reason to not do this? also, should I put in a master valve before the PRV for safety or is it just not worth it? It seems like I am reading that master valves are more of a problem than a help.

Where to blowout?

Help please. First time winterizing sprinklers in new house - previous owner said they would get the system blown out. I have shut off mains water from valve inside the basement. I don't see any access points/valves/bibbs other than the ones pictured here (including in the valve box - 7 zones). Apollo RP4A backflow. Any ideas where to connect compressor to blow out?
