Fortunately, 303 Sprinklers seems to be doing well. Matt is super responsive to both seasonal and repair requests. I like the convenience of scheduling on-line and receiving text confirmations and service windows. He always shows up when he says he will, does good work, and stands behind it. His prices are reasonable too. I needed a ball valve replaced, which he accomplished quickly then tested the system and adjusted some of the sprinkler heads. Another hassle free job.

My sprinkler backflow preventer was leaking so I hired Dan to replace it. His price was reasonable…read moreand his response time to questions was great. I was also having an issue with the drip line in my sprinkler system. He was able to find the problem quickly and fixed it at a good price. The issues we had are related to the copper pipe work. I would not recommend him for those types of jobs. On his first trip to our house, he left such a downward angle in the piping that I wouldn't be able to drain all of the water out in the fall. He agreed to come out and correct the issue. On his second visit, he redid the pipe work but somehow made everything worse. There was still a downward slope on the inlet pipe to the backflow preventer (see picture), and the outflow pipe was now crooked. I ended up paying another company to come out and correct his mistakes. I would recommend Dan for poly pipe problems. I would NOT recommend him for any copper pipe work. I don't think that's his area of expertise.

Susan actually picks up the phone. Alfredo shows up on time. Just with those two things alone,…read moreAction would be one of the best sprinkler companies in the Denver suburbs. But they do so much more! We have a really big backyard without having land, about 1/3 of an acre. We had a terrible sprinkler system installed by the previous owner that was truly a joke on covering our grass. A couple years ago, the worst sod company ever (Stay Fresh Lawn Services - never use them), did an absolutely terrible job extending our sprinkler system. Enter Alfredo, our lawn's sprinkler savior. I got three different quotes and plans on how to make our system work with our six zones that actually work. Alfredo's was not only the smartest plan, it was the least disruptive, required the fewest new parts, and it provided efficient coverage of our entire lawn. It was also priced better. About 70% of our lawn used to roast and turn yellow in the summer. With Alfredo's sprinkler design and installation, about 98% of our lawn was green through the whole summer. It was and is unreal. He showed up when he said he would every day, provided realistic expectations, and let me know what he was doing when plans changed or when he thought of a better way to do something. He made the project fun to be a part of, and he takes a lot of pride in doing it right. We found our sprinkler people for as long as Alfredo is a part of Action. We love this business!

When you have a busted head and water is shooting everywhere, you want someone there yesterday, not next Tuesday. The price was reasonable, though, I'll give them that. The technician knew what he was doing and got the head fixed pretty quickly once he arrived. What I appreciated was that he also took the time to adjust my Rachio controller settings without me even asking. That was a nice touch since most irrigation guys fix the immediate problem and bolt. The work itself was solid - no complaints there. The new head is working perfectly and hasn't given me any issues since. It's just that initial response time that knocked them down from what could've been a 4-star experience. Would I call them again? Probably, but I'd plan next time instead of treating it like an emergency. If you're not in a rush and want decent work at a fair price, they'll get the job done.

I would only recommend maybe a sprinkler blowout but no big jobs. He never came back to put the system on my phone or to show me what kind of system it was nothing I was out of town.

Sept. 2026: Came down the stairs one day and heard a huge whooshing sound, and I just knew my…read morebasement must have inches of water in it! Ran downstairs: nothing! Went outside...a pipe to the sprinkler system had busted because of settling or something over the past 26 years. (Go figure!) Called up A 3 in 1 Irrigation Specialists, and Nathaniel and John came out (on time, right when they said they would), and fixed the broken pipe in short order! I showed him another broken sprinkler head, and he made quick work of that too. Oh, and I needed a new bell thing, and he got me all fixed up on that also. A few weeks later I asked them to come back for 2 reasons: 1: When Rod Martin's Complete Basement Systems installed the sump pump in my subfloor, it shoots water out of a pvc tube up to ground level, then goes underground for about 20 feet before dumping out a vent thing in the yard. But the pvc was the lamest, thinnest kind possible, and going over the buried pipe with the riding lawn mower caused it to crush the pvc pipe down flat (underground, under the grass, but I could see little shards of white plastic here and there.) So Nathaniel and John laid down a new, stronger pipe for me. The 2nd reason they came is because I've been noticing that when it rains, the water does not go down the downspout and into the pvc pipe and away from the house, it just stays there overflowing right up against the foundation of my house. I had a plumber tell me about a year ago that the roots from the fir tree above the pipe had busted through the pipe, and there was nothing he could do without removing the fir tree! All's I wanted him to do was to roto root the pipe, but apparently it was too full of roots to do it, or maybe he figured it also had cracks and holes in it. So I let that go until I decided to let them remove the fir tree, because I thought it had to be removed to lay new pipe. Well, I had Nathaniel take a look, he and John dug to find the end of the pipe, and guess what? It wasn't the fir tree's roots, it was the big maple tree in my front yard! And the pvc was entirely intact! When they built my house, they ran the pvc from the downspout, to under the sidewalk, it went about 18 inches further, and then it just stopped! There was no cap on the end or anything, just good old hard Colorado clay soil. So as the tree grew, its roots found that if it went inside the pvc pipe, it would have lots of water, so that's what it's been doing for the past 20 years. Mix that with the leaves and dust that have come DOWN the downspout and into the pipe, and you have a nice big rope of small and large roots, mixed with lots of mud. So Nathaniel and John added some pipe to bring it further into the yard (additional watering for a very dry spot in my yard!), and put a pop-up drainage thing at the end, so that whenever it rains, the water comes down the downspout, through the pvc, and the pop-up thing lifts up an inch and lets the water out into my yard. The rocks around it help absorb the heavy impact of the water, until the grass grows nice and strong again, then it will fill in around the rock. And NOW those pesky tree roots won't have a way to clog the pipe again! Just look at what 20+ years of roots in a pvc pipe looks like! Like a 15 foot snake! Anyway, Nathaniel and John are my Go To guys now, they went above and beyond at every turn. Once they located all my irrigation boxes (there are 5), and by located, I mean they were covered with bark and dirt across 2 sides of the house, I mentioned that I would get some flags so that we can find them easier next time. Guess what? They quickly grabbed their flags and flagged them for me! And there was a lot of leftover dirt piled up after the new pipe was laid, and Nathaniel asked me where I would like for them to remove the dirt to. I said "Oh, I think I have an idea of where I want to put it (hidden behind one of my bushes), don't worry about it, just leave it and I will take care of it." But they would not leave a job a mess, and they moved all the dirt and mud for me, and of course replaced the sod they had to remove to lay the pipe. So like many others here on Yelp, I had a fantastic experience with both Nathaniel and John. Nathaniel is super great at what he does, and I trust his expertise, and am very happy with all the results. Thanks so much, Nathaniel and John!! :)
