Damien was awesome. He was prompt, knowledgeable and explained everything in details .

I called a couple places about my Noritz tankless water heater not working and was referred to Demian at Blueriver Plumbing. Demian was quick to reply and was able to see me within a few hours. I always expect the worse when it comes to a major house appliance not working, but Demian talked me through and showed me what the cause was. What I thought would be a major problem turned out to be a minor drain issue which Demian was able to resolve on the spot. Thank you Damien for being honest, thorough and for explaining what I can do to prevent my issue from happening again. read more

Demian was very professional and explained everything he was doing. It is clear he is very knowledgeable about tankless hot water heaters. My general plumber recommended him when I had an internal issue that needed repair. I will keep his number handy for the future. Thank you Demian. Chris read more

I don't normally write reviews but this time I will. I was grateful to find Demian of Blueriver Plumbing who replaced my Navien tankless water heater.. He was referred to me by another plumber Katie who said " he is the tankless water heater pro ". Indeed, she was absolutely right. He came , visualized the unit and started to work on the replacement. After it was completed, he explained to me in such a way it was easy to comprehend, how this unit works, the care and its maintenance. I am very grateful and satisfied. His knowledge, professionalism, diligent service and dedication to make a difference. Thank you Demian for all that you do . read more

I had a weird intermittent issue with my Navien tankless water heater. Demian came out the day I called even though it was after hours. He took the time to explain the issue with me and fixed the system. His pricing is fair and he doesn't gouge like many plumbers. If you need service or installation for a tankless water heater Blueriver is who to call. read more

I called and furnished a picture of my hot water heater as requested but never received a response

Our Noritz NRCR had an error code 70 & I got 3 expert opinions to fix it. The first Noritz "expert" recommended we completely redo & replace our entire 4-1/2 year old unit. The second plumber listened to my opinion that maybe it was the motherboard & got Noritz to mail us one (then ghosted me). Then Demian at Blueriver remotely researched the issue & concluded that the motherboard probably wasn't the issue. He explained that a Noritz motherboard may need to be rebooted (like any computer) to return to normal operation. His honest, fact based opinion saved us from giving thousands of dollars to the first plumber. Demian will be our go to source for factual solutions for future issues. read more

Working with Demian was seamless. I contacted Demian around midnight when my wife realized that our Noritz stopped working. I was also on travel on the other side of the globe and was out of options to troubleshoot and fix. Demian immediately responded to my messages and scheduled to visit as the first thing in the morning. I let him in remotely (as my family had left home for work), but Demian took care of it in 10 minutes and addressed the root cause. No over charge, no gimmicks - just get the right solution to the problem! True professional and highly recommend. read more

Demian is a ROCK STAR !!! Everyone once in a while you come across a person who restores your faith in humanity with their personality, honesty, work ethic, and professionalism. I just had one of those experiences today. How mundane and uneventful a Heat Exchange install in a tankless water heater can be? It all depends who is doing it and how is it being done. Demian is the principal of the school of tankless water heaters. He did it under 1 hour flat - Brilliant Job - Impressive doesn't do justice to his skill set, at one point I felt he could have done this blindfolded. He is a mechanical engineer who works with the top brands and knows his stuff and used to teach this. Fair, Economical, Efficient, and Professional - check check check. Excellent - Standing Ovation level appreciation. read more

From first communication to final install of our Norritz EZTR50 tankless water heater kit, Demian was knowledgable, personable, and professional. He answered our questions, explained everything about the system, and did an outstanding job in every way. I recommend him completely! read more

After several emails (I had a lot of questions) and then setting up an on-site appointment for an accurate estimate, I had Demian order a Navien NPE-240A2 for install. He was able to install within a week. He arrived on-time and started work immediately. Took about 4 and a half hours to take out the 12 year old Rudd and install the Navien. Now I get hot water in less than 30 seconds to the master shower (about an 80 foot run) compared to the Rudd which took 2 - 3 minutes. Walked me through the menu settings. A first rate plumber that is customer oriented. read more

Responsive to my requests, accommodated my schedule. Came out and discovered other issues so he was unable to do the job requested (flushing of tankless heater). Told me just to wait until the heater no longer works and then replace (dual setup so I won't be without hot water) read more

Our old water heater started leaking, so I called Demian. He actually came over a few years ago and fixed it from making a terrible grinding noise, and it worked great till now. This is an older unit, so it made sense this is the end of the life for it. Demian explained all the options, answered all my questions, coordinated the time with me, was very good about keeping me appraised as to when he was on his way, and finished the job quickly and well! I would recommend him to anyone who has issues with their heater. read more

This is the 4th tankless I've done with Demien and Blue River. Professional and considerate, he is always very responsive and thorough. Does some of the cleanest work you will ever see, extremely knowledgeable about everything tankless. This is the specialist you want/need for your tankless application. I've cheaped out before and used home depot no name brands tankless and standard plumbers. Demien had to fix. Hire right the first time and you won't have any issues. read more

Blueriver should be your first call for all thinks tankless. I was having an issue with my tankless installation. Rinnai said that the turbine was bad, which didn't make sense because the unit was new. I called Blueriver and he was able to diagnose the issue within a matter of minutes. It wasn't the turbine after all... It was the cold was in hot and vice versa. After this, he gave several suggestion on how to improve the previous installation. He helped me via text the following day and walked me through what needed to be done. He would respond within a few minutes.... Amazing! Blueriver should be your first and last call! read more

Demian did a great job installing a new Navien tankless water heater. The plumbing and gas line arrangement looks great. Took him just a couple of hours to install. He definitely has experience installing tankless water heaters. After the install he answered all my questions and took the cover off and explained the different components and how they function. read more

I called a few plumbing companies when our water heater stopped working due to combustion abnormality. One place was impossible to reach even though they are supposedly open 24/7, and a guy from another company basically said he wouldn't be available and gave me Damian's contact information saying he was an expert in tankless water heater and therefore, I could trust him with mine. So, I contacted Damian with that number and he was quick to respond even though it was supposed to be after his working hour according to the hours posted on the yelp. He asked some details and gave me a quote, which I believed pretty reasonable. And eventually, I was able to make a next day appointment with him. Considering that not having hot water is such a big deal and a huge emergency (at least to me, because I can't stand taking a shower with cold water at all and I like to shower every night), I really appreciated that he made time for me as soon as possible. He showed up at exactly when he promised to this morning. He took a look at it and knew immediately what caused the issue and fixed it right then and there! He also thoroughly checked all the other parts, explained the current condition of our water heater, and taught me how to maintain it to prevent the same issue. I asked a bunch of questions and he answered all of them without showing any sign of impatience. He also didn't mind taking a credit card payment at all unlike some other plumbers/technicians who frequently frown upon it. In a nutshell, Damian was easy to talk to, very efficient, highly competent, and honest. I was really glad with his service and I would absolutely hire him again when we have any problem with our water heater in the future. read more

Damian fixed out Noritz tankless hot water heater in an hour! This man is honest and has integrity!! He has the parts on hand. He knows exactly what was wrong and even put our pump on a timer. Which hadn't been set up. I called him an angel!! We had called several other plumbing companies with them wanting look at it! One company that came out tried to tell us it should be replaced! $6500 solution.) For wonderful service CALL BLUERIVER PLUMBER in Oceanside!!! if I could give ten stars I would have! read more

Before coming out to look at our water heaters, Demian gave us an accurate estimate (best case and possible worst case scenarios). He ultimately did the required maintenance on our heaters and replaced a broken shut off valve. I found Demian to be skilled and honest in our dealings. I highly recommend Blueriver Plumbing read more

I can not say enough about Demian. He saved us what could have been several thousands of dollars. I had a tankless water heater installed by another plumber in 2017. After about a year, we started to have issues with it. The water would get cold after about 3-5 minutes of using the water in the bathroom. I called the plumber that installed it to let them know and asked them about warranty. Their knee-jerk reaction was to say, " well, our labor cost is not under warranty. You would still have to pay for that." I did not ask for a freebie. I was only asking about the tankless since it was pricey to put it in. I then reached out to another plumber, and they came out and cleaned and flushed the unit as we thought this might be the issue. I paid their service fee, which was reasonable, about $125.00 for their time. After about a week, the same thing happened. The water would turn cold; we would have to go to the unit, unplug it, and plug it in again. A few weeks later, I called the original company again to see if they could come and figure it out because this was simply insane. To make a long story very short, another $500.00 for the few hours of them trying to figure out what was going on. It seemed to work fine for a few days, then back to its old tricks. At this point, we started dealing with the situation and more procrastination. However, it got to a point where it could not be dealt with any longer. We called two different plumbers that specialize in these types of water heaters. One quoted $1,800.00 to switch out to a new and similar model. The other company quoted me $3,000. We called the original plumber that installed it and told him what was happening. He said he wanted to come back and try to fix it because there is no way that a 5-year-old Noritz should not be working. After 5 minutes with no clue, he said he could give me a proposal for a replacement, which he did for $1,900. I was then fortunate to get a referral from another great plumber that I found who referred me to Demian. He told me that Demian specializes in tankless water heaters, and he can probably fix it quickly as he has the parts in his working van. And just like that, Demian shows up, approximately 20-30 minutes later he was done. $235.00 later, I now have a working tankless water heater. Thank you Demian! read more

Had an internal leak in a tankless water heater. Called them at 11:00 am and had someone on site by 2:00. He had the parts, was super efficient and clean work. Thank you for an awesome experience! Would recommend without hesitation. read more

Found a water leak in my Noritz tankless water heater at midnight. Found Blueriver Plumbing under Nortiz service website and cross referenced at Yelp. Demian was the first to reply from a group of Yelp requests at 7am. And Demian replied not with your typical call me back message. From the pics, he already knew the problem and gave me an exact quote. He also checked if my parts were under warranty without me asking. He came early afternoon and showed me the exact leaking parts. He walked me through the heater and answered all my questions. He was done in an hour. Everything from the initial quote, appointment scheduling, arrival, and fixing was very professional. read more

I want to give this plumber a score of 10 ! The owner of this business KNOWS TANKLESS WATER HEATERS! Blueriver Plumbing is listed on the "approved service providers" for Rinnai Tankless Water heaters. He serviced the system earlier this year with a cleaning and when you talk with Demian Franco you KNOW that HE KNOWS his stuff. Last Saturday we discovered: No Hot water! I called Blueriver and - - gasp - - he was out of town! Oh No ! What will we do??? The last 4 days I have talked to and worked with THREE OTHER PLUMBERS. All were mystified with the problem our tankless had. There was no error code being displayed, to give a clue as to what the problem is. Two of them told me what the problem is. We paid them $$$ and THEY WERE ALL WRONG ! And still no hot water. How much do YOU like taking cold showers? How do you like not using the dishwasher or clothes washer? What an inconvenience. How the hell people lived without indoor plumbing I will never know... but that is beside the point..... The point is: BLUERIVER PLUMBING ROCKS! This guy - KNOWS - HIS - STUFF ! He even has the parts!! Odds are good that he doesn't have to order the parts and wait for DAYS, for the parts to arrive!! I'd write more, but i have to stop now and go take a hot shower. ANY TANKLESS WATER HEATER ISSUES - - he services ALL makes and models -- CALL BLUERIVER Plumbing. NOW. read more

Had a 7am appt and they showed up promptly w mask on and ready to go. Demian was fabulous , fixed the issue in 30 mins and explained to me how my hot water heater was set up incorrectly by installer. To boot, he charged part of his service fee back to the manufacturer-and he didn't have to do that (I would have never known). I'm very impressed. read more

My 3 year old Noritz tankless water heater intermittently stopped working and displayed an error code on a Sunday evening. I texted Demian and he came to my house the following morning. He explained to me how some parts inside needs to be replaced and showed me and took the time to explain what is wrong. Pretty much he needs to rebuild or assemble new parts and will contact Noritz to send him directly those new and "improved"parts. He reassured me that parts and a big portion of labor cost will be covered by Noritz. At first, I was skeptical, after hearing from other people their not so pleasing past experiences with plumbers and not to mention my own experience with different plumbers. I'm pretty sure I made that gesture with Demian, lol! Then things changed, after hearing how knowledgable he is and showed his expertise with tankless water heater. He told me that as soon as he gets the parts and info from Noritz of what is covered and not, he will contact me via text and from there I can decide what I want to do. Sure enough about a week after, I had Demian to come back to re-build my tankless. I would say he changed about 80% of the faulted/worn-out parts inside, and only took him less than 1 hour to do it! He informed me that he gives a 30 day labor warranty and if i noticed anything not quite right that I should inform him. Sure enough, after a day... there was this constant noise coming from my tankless that I never heard before(although, it is working except that annoying noise). I sent a short video to Demian via text and within minutes he texted me back. He already diagnosed what is wrong and told me that he will call Noritz to send him 2 other parts that was not replaced because it was properly functioning until he replaced majority of them. In other words...he came back after a few days with those new & improved parts and replaced what is causing that noise(took him about 15 minutes). He explained to me that my tankless is pretty much brand new after he replaced "All" the mechanical parts inside. Up to this date, my tankless is working perfectly. I can't thank Demian enough for his professionalism and expertise. Not to mention, I found out that he is a mechanical engineer. That explains why he is so smart in this field. He can practically design and build tankless water heater with little sweat and half the time any other plumber will spend trying to figure out how to fix my tankless! He charged me a reasonable flat fee for labor and the best part of it... I didn't have to contact Noritz myself to inquire about warranty! He took care of all of that for me and he said he will get re-imbursed from Noritz for about 1-2 months for the labor part! I don't think a lot of plumbers will take that extra step, and that's how I knew that Demian is my guy for any tankless water heater! I WILL HIGHLY RECOMMEND DEMIAN to anyone who needs help with their tankless water heater issues. read more

Our Noritz tankless water heater is over 10 years old and quit working. Demian responded immediately and finished his troubleshooting and maintenance on our unit quickly.

Contacted Blueriver Plumbing to check out a gas combustion issue resulting in a loud groaning noise on heating start-up with my Noritz tankless. Demian came on the same day that I gave him my information on my issue and he arrived on time.

Will plan to use him again when I need repair/servicing or have to replace the tankless unit. read more

Demian Franco is a Tankless Water Heater GENIUS! I had a 6-yr old Navien that was leaking from the heat exchanger. This was covered by warranty and Navien gave me a new unit. BUT...the new unit was configured completely differently, so it required re-plumbing and re-venting. I was worried the labor bill (not covered under warranty) was going to be awful...but...it was not. Fairly priced, amazing service, and I am a happy camper! If you have a tankless system that has issues...THIS is the guy to call! read more
