John was so nice and helpful in explaining what the backflow does and what could be the problem (it was leaking a lot). Prior to scheduling the appointment, we received an estimate for repair and also a repair for replacement--- it was nice to have both options. No surprises. He ended up repairing it. He double checked after the repair to make sure nothing was leaking and he left no mess for me to clean up. He even had a few minutes to meet and play with Duke and Rocky (my labrador retrievers) I love doing business with nice people. read more

Finally! A backflow testing company that is professional and reliable. I've struggled in the past to find a legitimate backflow testing company. Let me tell you, this is them! The entire process was so smooth, One Flow Los Angeles surpassed all my expectations. Thank you! read more

I received a notice from the LA County Health that I needed to install a backflow preventer at my restaurant. I had no clue whatsoever what a backflow preventer was at the moment. After Googling what a backflow was I called these guys lol. They gave me a great quote for backflow installation and were really responsive. They even performed the backflow test and submitted the report. Fantastic service! read more

So here we are 6 months later and over $3000 spent and all I've for is a dead lawn! I've had john come back twice since he installed the lawn to work on the sprinkler system and ea time it's over $250 "sprinkler tune up" I've had several other licensed landscape companies come out this week and they all agreed the sprinkler system wasn't installed/designed correctly. Waste of money going with John and now I find out he isn't even licensed! I guess I'm just screwed..... read more

Called John to come out to give me an estimate for a valve replacement. He came on time and provided me with a competitive quote. I moved forward with the replacement ($120 approx) for the type of valve I had. In and out about 40 min. It's been about 2 months and everything works as new. Will use him again if I need to. read more

Wow. Where do I start. My sprinkler system is over 10 years old and I have 7 zones. Noticed problems with the timer, flooding, and low pressure - planters dying and certain spots in lawn not receiving water. John came out and did a free assessment. Ended up installing a new timer, repairing a bunch of underground breakage points, repairing some wiring, replacing a bunch of broken sprinkler heads, and performing a tune up all around. I would recommend John in a heart beat. He was professional and conscientious of my budget, walked me through my entire system (as well as giving me a quick lesson on a few things), and helped me determine what was critical and what can wait. He actually worked another day to finish the job and didn't nickel & dime me. He has very high work ethic and standards - you'll see it when he's on site working on your system while he provides periodic status updates and explains issues to you. There are certain people/businesses that you trust and want in your rolodex. OC Sprinkler, John, is now my go-to guy for sprinkler service. It is my great pleasure to write this review. read more

Relocated 10 sprinkler heads and fixed a cracked bubbler riser. Excellent work and post-job cleanup. Date of service 2/09/17. read more

My sprinkler system was very old and needed repair. We just planted new hedges and John arranged sprinklers so all of them get water and totally revamped our system. One morning I yanked on the hose too hard and broke our new sprinkler connector. John came out within the hour and fixed it for us. Recommend this company! read more

We had an issue with flooding where the gate valve or irrigation valve shutoff was. The guy went over our whole sprinkler system and told us where we needed to replace sprinkler heads, etc. He said it was a leak more to the street side of where the sprinkler shutoff valve box was. He said he would email an estimate and summary. Never got it. He did not return my texts either after he came out. read more

Decided to redo my flower beds and then part way thru it dawned on me that we should really redo the sprinkler system as it was from the 80's. It never worked that well and really relied on the rain to supplement, alas the rain does not come. Found this company on Yelp and read the history on the website and all the reviews and decided this was the one. Have not been disappointed. John and his crew are very professional and do all that is needed and more. They changed some of the sprayheads and nozzles, installed new valves, created a new pattern of sprayheads in the front yard, moved a couple to new locations and capped an unneeded one off. They then fine -tuned each nozzle. Am looking to forward to a much better watered garden and lawn with no water in unwanted places. Margaret E Morrissey read more

John and Orange County Sprinkler Service were by far the most competitive quote we received when looking to have our irrigations system fixed (compared to two additional local companies). John was also extremely professional and hard working. Our job ended up taking some additional work (an understatement) and John problem solved and worked very hard to resolve the additional issues. The additional costs were also more than reasonable for the extra work that was not part of our original quote. We are extremely happy with the high quality job John did on our property in Yorba Linda and we would highly, highly recommend him to anyone. Thank you, The McIntyres read more

I found OC Sprinkler Repair thanks to Yelp, and their quote was fair - so John came out today to work on my mom's Irrigation pipe issue. He got the job done in a pinch, and she is very happy. He offered to do an additional service on the Sprinklers in general, so she is taking him up on it - and I will update as to how it goes! So far, so good. Thanks! read more

I have used OC Irrigation Service several times, and every time John has gotten the job done for a reasonable price and quickly. If you need any irrigation work done I'd highly recommend them. read more

Literally the best people to work with. Our third year getting our yearly backflow checked for our small business and we will be contacting them again for next year and the years to come! read more

Very happy Orange County Sprinkler Service One of the zones in our automatic sprinkler system stopped working. We called OC Sprinkler Service on a Wednesday afternoon and they came out at 8am the next day. They diagnosed the problem for free (a 20+ year old valve had stopped working) and quoted a very reasonable price to replace the valve and surrounding plumbing in a very tight work space sunk into the patio. Repair was done in under two hours and everything works fine again. We will be very comfortable calling them back out when the next 20+ year old valve goes bad. read more

Thank you OC sprinkler ( John ). We had an emergency leak. So I called John yesterday to ask him when he could come and fix and he said he can do it at 6:30 in the morning today. What a great service. Thanks Oc sprinklers you are awesome!!! read more

After receiving a few quotes from different companies on yelp I decided to go with OC Irrigation. John helped me redo my front and back yard. We added about 10 sprinkler heads and a new control panel to my system and my grass is looking better than ever. I have already referred the to to my family. Thank you! read more

Super polite and answer the phone quickly! Good job by John replacing our sprinklers heads!

John came out gave us a very reasonable estimate for putting in a backflow valve to our raised sprinkler bed, plus also diagnosed a leak in our lawn within 5 minutes. We had another technician come out from another highly rated company who wasn't able to find the leak. John found it immediately and also fixed another leak in another area. Extremely knowledgeable, intelligent and efficient. I could not give a higher recommendation, call John immediately for any sprinkler issues. He'll solve it! read more

John did a great job of bringing our 23 year old sprinkler system back to life, working two long days to make sure everything was back in working order. Would highly recommend! read more

John was great to work with! Came in for an inspection and got right down to business. He quickly identified multiple issues with our current irrigation system, and identified solutions to correct them. When he came out to do the work, he was efficient and did the job well - no cut corners here! Others have mentioned his lack of communication, but I didn't have any issues. He's clearly a busy guy, which he should be because he does great work. Thanks John! read more

John doesn't not return phone calls. Been calling and left messages for two weeks. Still haven't heard back.

They do not return phone calls. Left a voicemail weeks ago, still no call back. If they are not taking on new projects, it should say so on their Yelp or voicemail. read more

I couldn't be happier with the job that John completed on my sprinkler system. He was prompt and responsive to my request for a quote and then did the job on schedule and at a cost that I could live with. And beside that, he's a very polite and personable young man - I would recommend him to anyone. read more

John and CARLOS were AMAZING. They replace all 9 valves, adjusted every head, replaced heads, fixed broken pvc, and best of all replaced the timer with a new WiFi timer so I can use an app in my phone to adjust the watering times from wherever and whenever. So so happy, highly recommended!!!! read more

Honestly, this company is the definition of professionalism. I recently purchased a fixer-upper and the repair of the landscaping was what I had thought to be beyond human aid. They certainly proved me wrong. Not only did they accomplish the improbably task of taming my property, they took the time to provide me with the knowledge and tools to maintain it myself (unlike other companies I have used in the past). They did a masterful job, my mother ALMOST CRIED on Mother's day when I had my family over for dinner! These guys are reliable, quick, cost effective, knowledgeable, and MOST importantly; FREAKIN' GOOD! at what they do. I recommend to any one. -Much appreciated. read more

Couldn't be happier with John's work. We only needed a repair this time around for a job that wasn't done right by another guy. John was pleasant and caring. He gave us a fair and thorough estimate and was able to get the work done right away. It looks and works great now!! I would recommend him to anyone. Thanks John!! read more

I woke up to a flooded front yard from a broken sprinkler. I called Orange County Sprinkler Service and said I needed same day service. I didn't expect to find anyone able to do that, but luckily I called these guys. John was over in no time. He was quick to fix the sprinkler and also spotted some other issues which he managed to fix as well. He also gave a tutorial on how to program the sprinkler system. We just moved into our place, and we're clueless. He fixed the programming so the days and timing were watering the plants correctly instead of drowning them or drying them out. I'd recommend them to anyone and plan on having them fix future problems that we might run into later. read more

John replied quickly to our inquiry to setup an appointment for a free assessment. He came by a day or so later and gave a thorough evaluation of our front sprinklers. He found the issues with our poor flow and coverage and provided a good estimate within our stated budget. He and his coworker came back a week later and changed out a valve, located and replaced a broken/leaking head, moved one head 2' for wider coverage, and tuned all the heads. Our front sprinklers work great now with excellent coverage with half the watering time we were used to. There's essentially no evidence of the holes they dug! Excellent service we're happy to recommend and revisit if needed. Thanks John! read more

John and his crew are awesome. From start to finish, my wife and I were impressed with John's attention to detail, great communication and quality of work. His estimate for a total rework of our system was thorough and fair. He and his team showed up bright and early each day and finished our project in great time. Our new sprinkler system is more extensive than before and it better services and waters the lawn, flower beds and raised garden plots. The drip lines have saved our lives and are already giving our veggies more water than we were getting them. Overall, a great experience and an outstanding service/product. I highly recommend hiring John and his team! read more

John was on time, very friendly business owner. Extremely fair price to fix a sprinkler head and replace wires to my solenoids that my dogs chewed off. Very pleased with his service and did the job in a timely matter. read more

John was able to come out days earlier than scheduled due to a cancelation. It was so nice to have a contractor who will text you with updates on his arrival time as well. He gave me the most honest and competitive quote. Explained everything he would do and in a very timely manner. John performs the work with his guys so you know your getting exactly what was quoted. John is also a really good guy and I would recommend him to anyone. read more

My valve bank had a pipe break, so, I called John to give a quote on repairing it. He answer the phone quickly arranged a time to come out. The value bank had to be completely rebuilt in order for the pipe to be replaced. John gave me a fair bid and set up a time to come back to perform the work. Arrived on time and quickly did the work. I would high recommend Orange County Service. read more

We called OC sprinkler service on Wednesday and our problem was fixed by Friday afternoon for half the cost of other quotes from other companies. John was polite, professional and respectful of our home. He was upfront with the costs and needs of our project. We will definitely call again for our next project. read more

We had an old sprinkler valve not working and a second valve just as old but still functioning. We called John for an estimate to replace the bad valve. He was prompt upon arriving and gave us a quote. He also made a suggestion to address both valves vs. just fixing the one. After some thought we went with John's suggestion. This was not the "easy option" for him but a good one for us. A long term solution versus just a repair. We made the appointment to do the work. John was punctual, and made the change and we are very pleased with his service and workmanship. Definitely would call John/Orange County Irrigation Service again. read more

The best sprinkler installation and repair company in Orange County! John came to my house 2 years ago because I was tired of watering my backyard by hand and they installed an amazing sprinkler system at a very good rate! I recently called him back because I needed to move two of the sprinkler heads to another location due to a new bbq area I'm installing, he came out on a Saturday and moved both sprinkler heads and adjusted them to perfection! I'm very satisfied with the quality of service he provides!! read more

Spent a few hundred ($350-$400) on sprinkler repairs. Saw some pretty significant improvement in a few few areas but really no improvement in the majority. The sprinkler heads that were installed didn't provide the coverage needed or were the wrong type for the need. They consistently over shoot or undershoot. Tightening or listening the sprinkler head just controls the flow but ultimately the solution provided in this instance was inadequate. Had several issues with the new sprinkler heads installed. read more

First of all let me say that John is very courteous. It was nice that when I meet him, he shook my hand and looked me in the eye. John also showed up 10 minutes earlier than his schedule time to be there so that was refreshing. I told John that that my sprinklers in my front yard were flooding the yard and that I thought that the solenoid might be stuck open at the end of the cycle. I also have a ton of over-spray and asked John what i needed. He first took a look at my control box and told me that this box was "Overly complicated, but simple to understand". He spent 20 minutes reprogramming the box. He told me that the box had preciously been set for the front sprinklers to go for 3 hours! wow! I then asked him what else he thought I needed and he told me i need there tune up and that would be $149.00. I asked him how much for programming the panel and he said that would be $79.99....I thought that was a lot for 20 minute reprogram, however, I decided to do the tune up and John included the re-programming in for free. So I gave him $175 because I wanted to support a young man running his own business. Then came the first night, all 6 stations ran continuous, back to back for 4 hours and flooded everywhere. I turned the water off and called John later in the day. He said he would meet me the next day. The next day out of nowhere he text me and says his partner came to my house, unannounced and without setting appointment and reprogrammed the panel without me there. He also states that this guy has 25 years in the business and everything should be fine.... Next time the sprinklers came on, all the cycles went great until the last station, the front sprinklers again ran for over an hour and flooded the front again! I went ahead and texted John the problem and he wrote..."the diaphragm of the valve must be sticking open (even though he told me prior the box was set to run for 3 hours), we charge $89.00 for that but will take off $20 for the inconvenience"....no thanks I will have to go elsewhere for sprinkler service to get this fixed now. read more

I got a quote from John based on the Yelp reviews. He came out quickly, gave a reasonable quote and reworked all of my old sprinkler valves quickly. Also installed a new outdoor timer and rewired the valves. Looks great and works great. Definitely recommend. read more

I work 8 - 5 and John made time in the morning according to my schedule. He got the job done quickly and checked his work. Very trustworthy and knowledgeable. read more
