How to fix an irrigation sprinkler zone that is not working

[@alexiluther]

10 years later and this is still one of the best, clear, and concise videos on the topic of sprinkler zone troubleshooting. You covered a lot of ground in a short amount of time logically and methodically. Very well done.

[@shelterrockisland]

10 years later and still the VERY BEST troubleshooting video and explanation for an irrigation system. I recently had a lightning strike near the house and various things on GFIs and surge protectors fried in very odd ways. Some transformers fried; some power supplies exploded; some wires fried but the end units were fine; in the case of irrigation system control/power box is fine but won't activate solenoids. This helped me troubleshoot and it turns out power wire to solenoids is fried somehow. Can't explain it but this HELPED!!! Now I need to fix it.

[@KittyHerder]

I took a class in irrigation and learned a lot, but we covered installation and not repair. I emailed my teacher for advice and he described what to do, which gave me the technical terminology to find videos This is exactly what I need to do and I'm pleased you have the same kind of valves, which makes it easier. Now I just have to buy an ohmmeter and not electrocute myself.

[@jacribb]

I was talking to some co-workers and they thought that it may be the ground as well. I will take a look at it tonight when I get home with a multi-meter and will check the panel. Thanks for the video btw. Very helpful.

[@MrDiddy74]

Thank you! As a mom of 6 and a hard working husband, I try to learn how to fix things around the house myself. This was the fix to my problem! Thank you for making it so easy!

[@JEHaddo]

I like this guy. Very straight forward, relatively easy to comprehend, and straight to the issues. Good job!

[@spelunkerd]

Thanks, man.

[@idkwatnametoput1468]

Thank you after a month and a half of calling my sprinkler guy and he never showed up I decide to google this is very problem and your video was first to show up and I'm glad I saw it because my sprinkler system is working perfectly now thank you

[@Iscaper]

Thanks Dave. I like how you started at the timer and systematically went through all the sprinkler zone components that could have been a potential problem. Very well done!

[@rickdelgado7112]

great diagnostic and solution process, Ive been a professional groundskeeper for over 14 years and it really bothers me when others give inacurate suggestions on irrigation repair however this is a great example of proper troubleshooting and I really recommend this video to anyone seeking proper advise on irrigation repair,GREAT JOB!

[@JimboHurt]

Very awesome knowledge and skill with the multimeter etc. I learned a lot from your video on how it worked but then I took the lazy approached and put one solinoid from a working zone and stuck it on, ran that zone, it made my broken zone work, boom solved. Replacing the solenoid is my confirmed fix!

[@progers5019]

I have some a zone not working properly. This video helped me on the troubleshooting end. Very well done. Everyone is on different levels of expertise. If you are savvy in mechanical and electrical things, it is very easy to follow. Well done Thanks

[@spelunkerd]

Irvin Rogers Thanks, man!

[@zx8401ztv]

I dont have sprinklers but your systematic methods are A1 mate :-) Hey you cant make videos if your life is complex or nothing much happens so never worry about us tubers, its your channel and your not contracted to make videos for us :-) Washing machine water input solinoids often go the same way.

[@donaldpeyton2341]

Thank you. Mystery solved. The actual leak was a good 30 feet from the leaking PVC connection, actually coming up at a joint in the sidewalk. Lots of digging in the mud, the family dog enjoyed the work. On to the next home repair adventure. Thank you so much.

[@spelunkerd]

Thanks for the followup, I"m sure others will find your example useful.

[@jillmeesey683]

This explanation was great. The replacement went smoothly. The landscaping company that put in the irrigation system didn't use the waterproof wire caps, so I upgraded all of those when I replaced the solenoid. Since I live in Sacramento and we only have two seasons, summer and not summer, I covered the wire connectors in a plastic container. I scored the bottom and popped them through with the the top on of course., I can replace it as needed. Thanks!

[@spelunkerd]

That's a good plan. If you are looking for an inexpensive substitute for those specialized connectors, look for "dielectric grease" in any autoparts store. One tube will last a lifetime, and you'll find lots of uses for it if you do any kind of auto repair. Some technicians put it on every electrical connector they open, to prevent oxidation and electrical shorting. The grease is a nonconductive barrier to water, oxygen, and other impurities.

[@kc8ncr]

Terrific video on troubleshooting a sprinkle system. In addition to covering the topic in depth, the explanations and camera angles are really top notch. This video should be used as an example of "how to do a you tube video". Very high quality video work and consistent audio levels. Great job Spelunkerd!

[@spelunkerd]

What a kind remark, you made my day!

[@Kanoee64]

I agree with Doug B

[@benpreister990]

Hello I'm we doing my garden as well it looks really good I'm doing it professionally. My parents have the exact same system you just showed I know it well and the how it was built

[@OzzyMoto2K10]

Awesome video - you've helped me a great deal, thank you!!! We moved into our new home last Fall and it has been a fun adventure figuring out how everything works inside and outside of the House. Today, after Spring blooms eternal in Minnesota and Winter fades away, I opened the valves on the outside head unit, then did the same off of the water main inside. I went to the Sprinkler Panel in the Garage and manually switched between the zones. No Water, No Sprinkling. Went next door to our new neighbors and asked if the system had worked last summer (they said, "Yes, and nice to meet you!"). Clearly, I was doing something wrong. This is where you come in -- after watching just a brief portion of your informational video I learned that I should go check the solenoid position for the valves in the yard -- sure enough, they were in the closed position. A 1/4 turn clockwise and I was in business, happily switching between zones to see what kind of water coverage I had at each zone. Thank you, again!!

[@spelunkerd]

+Ken Osborn No problem, thanks for the followup. If you live in a frost area, remember to carefully blow out each branch of the system, one at a time, with compressed air in the fall. It's pretty easy to do if you have a good compressor, with as large a tank as you can afford. You don't want high air pressure but you do want a good volume tank. I routinely leave all the solenoid valves open in the winter to avoid pooling of any remaining condensed water behind the valve.

[@wingsstringsandreallysharp2535]

Thank you for your helpful videos! I now have enough knowledge to tackle my dead zone in my sprinkler system. Before watching your videos I had NO IDEA what I was getting into. Appreciate your help very much.

[@leecannan8805]

This is PRECISELY what I needed! Clear, condensed, and accurate. Thank you for your help and saving me some money 👍🏻

[@The1Beav]

Very helpful. I was told my common wire may have a shortage, so this video helped me to test for bad wiring.

[@rylsta6590]

I found the valve this afternoon. My parents just moved into a new house and we have pop up sprinklers and since I have been hear I have been trying to find this valve. But thanks to your help I found out where it was and the problem and why it wasn't working. Thank you so much

[@spelunkerd]

Hey, I'm glad to help. Thanks for the followup!

[@WrenchingWithKenny]

I enjoyed how you explained the process !! Well done !!

[@spelunkerd]

I find it interesting to see how you have the personality to cultivate a dedicated following of viewers, soon to eclipse my subscriber list in the next couple of months. My videos on the other hand are almost all found through Google searches by homeowners who have a problem, wanting a deep dive into understanding how their system works. I admire people who are able to captivate an audience, but in any case these humble old videos still serve useful a role.

[@Iscaper]

Excellent video on troubleshooting a sprinkler valve.

[@JerrePaquette]

Nicely done. You have a pleasant manner, effective when one of us is panicking at the other end. I'm on my way to get a voltage meter--been putting it off. Thanks for your care and help.

[@spelunkerd]

Thanks!

[@spelunkerd]

And thank you for the reply. Electrical solenoid problems are not very common, but when you understand how they work the whole system is that much easier to understand.

[@fmundo2]

This guy knows what he's talking about. Video is paced well and thorough. Well worth a watch. I'm a novice in this electrical stuff, but now want to get into this.

[@blitzkreegy4232]

Excellent video. The all in one complete sprinkler problem solutions are in this informative video. Great tutorials thanks!

[@patrickfrausto9866]

Thanks for the video. I've replaced the solenoids before but just did it by trial and error. I really appreciated the meter readings for troubleshooting electronically. Haven't been able to find that any where else. Thanks again!!

[@spelunkerd]

Thank you for the kind feedback!

[@Ki-Lessons]

Very nicely done video, one of the more professional on KZbin. You voice is so calming, you remind me of Bob Ross.

[@spelunkerd]

Thanks!

[@thomasscoville1148]

Oh, this is a riot: I've just finished a big hardscaping/remodeling project involving a six zone irrigation system. My guys couldn't get it working, so I had to roll up my sleeves, bust out the continuity tester/voltmeter/line tracer and diagnose it myself. When I was probing the bad solenoid hypothesis, I pulled up THAT VERY SAME VIDEO. Seriously. About two weeks ago. I remember thinking that guy was very helpful.  Turned out to be the Rain Bird controller; when you short out one of the circuits, the controller takes that zone out of service until you fix the short and reset the controller. My guys had shorted out half the circuits while thrashing around with the lines. They got them all straight, but they never reset the controller, so confusion ensued. Speaking of Bob Ross, are you aware of the whole ASMR cult? it's actually huge business on KZbin.

[@Ki-Lessons]

Thomas Scoville spelunkerd I had the sprinkler system installed in the house I'm in right now years ago, when I was traveling. Now that something was wrong with it, I had to both familiarize myself, as well as learn the interface to my controller, remember pascals law so I could recall how these valves work, pull out my multi-meter, and remember where everything comes and goes, because in America no one marks anything (very odd). When I got to my first valve I realized I should do a quick check on the web. While I know how all of it works, it was really wonderful having someone just calmly walk through the 1 2 3 of it. So, I walked back outside, started at the controller, and followed it to its end. Of note, everything is working now, not because I did anything clever or smart, but it seemed ultimately that unscrewing the sprinkler valve assembly, and just putting it back together again made everything happy again. I'm now going to label everything, and draw arrows for water direction on the pipes.

[@Ki-Lessons]

Thomas Scoville ASMR - Yes. LOL I even know people into it.

[@thomasscoville1148]

Reichart Von Wolfsheild oh, labeling is a pathology with me. Compulsion. I have a label maker, a dozen different kinds of line tags, and fine line sharpies at the ready. You should see my work in the server room and the punch-down block. In a similar vein, you might want to check out www.reddit.com/r/cableporn. Not what you think: it's a forum for OCD server-room line jockeys. Lots of zip tie embroidery and Velcro straps and color-coding schema. We obsessives take control where we can. 

[@spelunkerd]

Thank you. Solenoid problems are a lot more rare compared to the more mundane issues of water pressure, leaking seals, and incompletely closing valves. But if you understand how the solenoids work, everything conceptually slides into place.

[@jayg461]

Hi! I just watched your video and it helped me diagnose the problem with my sprinkler system. I just had to replace the solenoid. Great video! Thank you!

[@spelunkerd]

Great, thanks for the followup, I'm glad it helped.

[@vfb07]

Thanks buddy. Helped me fix one of my stations that wasn't running. Very thorough and informative!

[@spelunkerd]

You're welcome, I'm glad it helped.

[@donmacdonald494]

Very well thought out and organized. Breaks done the steps easily so the real problem can be fixed quickly and efficiently. Nice job. Because replacing the whole valve is more expensive and if the trouble is in the wires or in the timer is a waste of time and money. Thanks DM

[@spelunkerd]

Thank you, Luke. Most guys who know their way around a DVOM will have no problem with this. For others who need more help, this may not be enough. Mostly I worry about walking people down a pathway that is too difficult for their skill set. Nice to meet you.

[@TheJosa007]

Thank you much !!! I did not know much about sprinklers, and now I do. I appreciate your time

[@tomificationable]

Thanks to your video, my problem is fixed ! Very helpful video for a person like me, who doesn't know much about this stuff. Thanks!

[@spelunkerd]

tomificationable You're welcome, thank you for the feedback.

[@Regg363]

I troubleshoot electronic control systems for a generation station so I understood your troubleshooting method. This video would be very helpful to someone that isn't familiar with electricity, meters, ohms or voltage drop. Very good video.

[@JoeHeuser]

Very systematic approach. I totally agree with the previous comment. That's exactly what I was looking for. Well done and thank you!👌

[@alijhi]

Pro-tip Marette in Canadian = wire nut in the USA. thanks for the nice video and greetings from Florida

[@DJDevon3]

Just moved into a new place and there is an existing irrigation system. Officially just moved in today. No garage though. :( I have an almost identical Pro C irrigation controller as you! One of the heads is a geyser so I went looking for videos and voila, amazing that you covered this a decade ago. Great video as always. Hope you are doing well!

[@spelunkerd]

Hey man, it is so nice to hear from you, after all these years. You still working on cars? I did another more recent video on how the valves work, they have an intriguing design. Around this time of year, sprinkler videos get more action, ha ha.

[@spelunkerd]

You make a good point, that techniques used in one situation will often find application in others. Specifically voltage drop testing principles definitely apply here. Thanks for your input!

[@spelunkerd]

What a kind remark, thanks Dan. I spend my time fixing cars and there is considerable overlap as far as techniques go. One technique I refer to here is voltage drop testing, which is a critical part of automotive diagnostics. If there is a voltage drop in the wire it means there is a bad connection somewhere, and by doing the test you avoid unnecessarily replacing parts. I show how to do that in the starter motor video on my channel. As far as normal values, I found them on the 'net. Dave

[@sjharwick1]

Thanks, just fixed mine, so great that others help spread their knowledge

[@hariniashishtrivedi8301]

very good step by step process that explains how to detect for problems and how to fix it.

[@spelunkerd]

Thanks!

[@teslabulls1238]

I like your videos. Your explanations are so easy to follow.

[@spelunkerd]

And thank you, back. I was happily surprised to be successfully using an automotive technique, voltage drop testing, on an AC system.

[@petersonfamily6223]

Great video and you answered all my questions and demonstrated what to do as well. Well done and it helped me diagnose a bad solenoid.

[@EMTdrummer]

Right to the point, good technique, good camera work... great video overall. Thanks

[@spelunkerd]

Thank you.

[@jlchambe77]

Thanks for the help, thanks to your video we were able to tell that the problem is in the wires. Now we just have to figure out where.

[@spelunkerd]

Finding a broken wire can be tricky if it's in a garden. There are moderately expensive tools to help do that (trace wires and find breaks), but for a big area it might be simplest to just run another wire. Before doing that double check the connections at both ends, which are always problematic areas. Good luck!

[@jlchambe77]

+spelunkerd luckily the wires are bundled, and we had a few redundant wires, so we just swapped in one of the unused wires at both ends and it worked like a charm.

[@SteveRobReviews]

I don't have a system but the testing was fantastic. Thanks

[@Polycreosis]

Great video - very clearly explained. I'm in the first house I've ever had with a sprinkler system, and it helped me better understand how it all works. Thanks for uploading!

[@spelunkerd]

Thanks! I did a few other videos that homeowners might find interesting, too, including a couple on hot water tanks.

[@spelunkerd]

That's the most meaningful compliment I've had in a while, Rick. Thank you!

[@TonyCota]

Thank you! I had a feeling the solenoid was bad, but this video confirmed to just replace it!

[@spelunkerd]

I"m glad it helped, thanks for the followup.

[@bobmartin3]

Excellent no nonsense, straightforward video. Thank you.

[@spelunkerd]

Thanks!

[@robmanriquez6727]

Excellent, well illustrated and explained very clearly.

[@hp11208]

Very good info and system diagnostic,now the grass will be green.

[@stevesifton2063]

I'm a quality engineer by trade which means I understand this stuff but have no clue how to do it! Thanks for a VERY simple video. Thanks to you, I root caused the issue as a bad solenoid (only 1 zone not working), replaced it, and it is working again. Total cost ~$10 instead of calling someone and paying who knows what when they get around to it. Thanks for saving me time and money. If you're ever SE Michigan, I'll buy you a beer!

[@spelunkerd]

I love remarks like this. It says I'm hitting my target audience, guys like you and me (grin).

[@spelunkerd]

I'm glad you chimed in, Gregory. Yeah, you're right, and if I had a spare solenoid that would probably have been my approach as well. But for an amateur it would have meant buying a new part before deciding whether it was broken. I did consider swapping the solenoid with one of the proven ones adjacent. But that would have involved more work, and to properly test the wires it would mean completely swapping it. Thanks for your input!

[@maxcy3]

I love your videos and want to thank you for thorough, clear explanations of the problem as well as the solutions. My understanding and confidence have improved from viewing your videos. I no longer freak out and wonder how to shut off the water and wonder whom to call. Again, thank you.

[@haseebahmed6278]

Awesome Video! Thanks for helping the rest of DIYers :-)

[@kimgreen945]

awesome job explaining! I troubleshoot my sprinkler system quite a bit and its a hit n miss way I do things....getting soaked quite often☺ Thanks for the explanations and also how to use a voltmeter! thanks n wish we were neighbours!!🌞

[@spelunkerd]

What a kind remark, thanks for the followup.

[@robertmartinez1645]

Thank you so much! I just discovered that 2 zones were not working. I followed your other video and cleaned all of the insides of the valve and still no go. I'll try this. Cheers!

[@BillCooperOK]

Makes perfect sense! I have a bad solenoid. Will be replacing this weekend. Thanks!

+Javier Lopez Thank you.

[@bulkybiatch6811]

Dude thanks for sharing. My valve ended up replacing the filter.

[@mikeschumacher9715]

Loved the video and very helpful. I usually just start with swapping out the solenoid for a good one and work back from there. Usually it is the solenoid. Thanks for making an sharing this with the world. Sure helps a lot.

[@spelunkerd]

You make a good point, that is the technique used by many professionals who have replacement parts handy and who can easily recognize the situation. Coming from the auto repair field, some parts are special orders and hundreds of dollars, so it makes sense prove the part is bad before replacing it. I like testing because it gives me insight as to how the system works, and it doesn't take a lot of effort to do the testing.

[@tomdavies9708]

This video was very helpful. I will try this series of checks tomorrow.

[@spelunkerd]

Thanks, I'm glad it helped!

[@brentcos9370]

Great sprinkler fix video! Thanks for sharing.

[@spelunkerd]

Thanks!

[@travisserio469]

Great video thanks a bunch! This should definitely help me diagnos a large non functioning system on a house I just purchased.

[@spelunkerd]

***** Thanks, man. The first things you should check are, first, the manual shutoff valve inside the house. Then check to be sure that the solenoids are all manually closed. Over winter, most homeowners leave the solenoids manually open so that water can't pool near the valves, possibly destroying them in a freeze. That's usually done as the final stage after blowing out the circuit with compressed air in the fall. If you try to restart without closing all the solenoid valves, then every valve is left open and the water can't build up enough water pressure to drive any sprinkler head.

[@travisserio469]

Thanks! So far ive had to repair a break in the line where a new main water line was installed and broke the irrigation line in two. Luckily my system is lake fed and I was able to get the pump up and running after replacing a bad relay. Ive manually opened all of the values and I have at least 1 that is stuck open and 1 with a broken solenoid line somewhere between the timer and the solenoid (fun). Sadly it was in the high 90s today so I surrendered after fixing the water break. Tomorrow's another day! 

[@spelunkerd]

***** The broken wire problem can eat a lot of time. If you've ruled out a connector issue it's sometimes easier to run a new line. There is a device, colloquially called a 'fox and hound' tool to help hunt down a broken wire, but those can be expensive. You could make your own fox and hound set with headphones and some kind of electronic noise generator, but that would be a weekend project, too. Good luck!

[@travisserio469]

Yep im planning on running a new line. Not even gonna try to find the break lol. Thanks for all the help!

[@divindave6117]

Yesterday I was troubleshooting my sprinkler system and used this video as a guide. (great video btw). 2 of my zones weren''t coming on. After measuring for voltage and resistance, I was convinced the solenoids were bad. But was not the case. After a whole lot of head scratching, I started disconnecting and connecting wires and ultimately I determined that I had a 25 volts on each terminal of the expansion module when there should have been voltage on the 1 terminal at a time, so multiple valves were opening but the zone wouldnt work due to lack of pressure. I replaced the controller and all works now.

[@dogsbyfire]

Fantastic video! Truly professorial. Thank you!

[@caseykjolhede3993]

This is exactly what I needed...love the Canadian accent too ! Thank You !

Thanks, I'm glad it helped. Funny how people talk about my accent, I never noticed, ha ha.

[@LukeWooz]

Great video! Very informative and well put together. You do a great job of articulating the steps as you take them. I am going to use this to help troubleshoot my weak sprinkler zone. Thank you!

[@robinsonsauto]

Great job, like mentioned in the previous comment i like the systematic methods you use as well, starting with the basics to a complete test of the system = a job well done with no worries, Thumbs up, in addition im adding you to my recommended channel list hope you don't mind. Thank you for sharing

you saved me a lot of time by including those first 30 seconds :)

[@ronaldelsis7603]

Very helpful video. Really helps you diagnose your system. I think I may have a dodgy solenoid as it works sometimes an not others. But at least now I know.

[@spelunkerd]

Thanks! I'm working on another sprinkler video right now, this time with a valve sticking open.

[@thechasecomplex]

Very helpful, thanks a bunch for taking the time to make such an informative and comprehensive video.

[@spelunkerd]

Thanks!

[@johnhurtado440]

Sir, you did a wonder full job explaining all very succinct. Keep those excellent videos coming. How about doing a video in locating irrigation valves that are buried!. I saw some videos but you are very articulate, so you could do another great video on that. thank you so much.

[@derekdyer3929]

Appreciate this video and information, checked mine out to find it was simply a broken breaker switch, popped it and the unused sensot open swapped the broken breaker switch for a good one and presto, Zone two is Aive!

[@GeorgeIreton]

Perfect! A great explanation and demo. Just what I needed to know. Thank you friend!

[@evanthayer5374]

Informative video! Thanks. I think my issue is the solanoid too. All I could think of the whole time was "this guy is so canadian"... You might not think you have much of an accent, but you do. I'd guess Alberta, but could be anywhere.

[@spelunkerd]

Yes, originally from Alberta, ha ha. Thanks for watching.

[@11brittanyleann]

Great video. I understand how to check out the solenoid.

[@MrRondeezzee]

great video first off, I have a issue with one of my zones. the problem I'm having is when I leave my lawn to work off the timer the pressure at the sprinklers are low but if I manually do it at the diaphragm the pressure is fine.

[@spelunkerd]

Some systems have a manual control that will adjust how much the valve opens with the solenoid, I would look for and try that first. Make sure the solenoid is tightened all the way down, and I would remove it carefully and clean the seat. If that fails you could temporarily swap a neighbour solenoid to see if it works better. If it does, then it's time to replace the solenoid, they aren't very expensive.

[@MrRondeezzee]

Hello sir thanks for the prompt response been 5 tears for this video. I'll check that. My diaphragms are the same as the ones in your video

[@kevinyork4757]

That was a good video: Constructive criticism, because this is new to me. Show the bushing and what it looks like. I have never seen one. When you were screwing it in, try to start it off where your hand is not blocking it... or at least show yourself starting it off with an unblocked view. Still Excellent...

[@spelunkerd]

Thanks, man, you're right. I've rarely made a video that I didn't think was glaringly amateur in some way, and especially audio has been a steep learning curve. There's a balance between showing everything and keeping viewers entertained. Showing every step is better for serious viewers, but I try to respect the time of all viewers by reducing how long they need to sit still, ha ha!

[@edawriter]

Thanks, most helpful. I followed your instructions and, sure enough, it was a bad solenoid. $9.

[@spelunkerd]

+edawriter Thanks for the followup, it's always nice to hear of success like that.

[@danjimenez2985]

Best diagnostic and repair of sprinklers I have seen. Very thorough! Thank you so much. I would love to see a how to use a voltmeter from you or how to set it properly for each application. How do you know what the resistance or OHM ranges should be? Cheers, Dan

[@spelunkerd]

You twist the plastic control arm below the solenoid counterclockwise to get water. If you don't get water with that, but you do get water in all the other zones, look for a supply problem, either an obstruction OR a leak within that zone. If a leak causes a fall in pressure, the heads won't spray. Look for a leak, and if no leak take heads off, one at a time, and flush the line. You may need to clean the valve. Look for kinked supply lines. Good luck!

[@denniemelton206]

I was trying to point when I see some one has not put right Wing nuts at time I repair stuff. I point it out to customer and replace them. All as up grade convenience for better customers relations also. Plus if there is any change in Building Codes etc plus Industry Standards is always good PR.. I would rather lose few cents on replacement of Gel nuts. However rest of information is very good. Thanks for pointing it out to the Folks Great job.
