A power outage fried the computer of my prior tankless water heat after a rain storm. I was referred to RJ Plumbing, in particular John, by a close friend. And Man, am I glad I asked for a referral! John came by within 1 hr of my initial outreach to check out the situation and set up. After it became clear that a replacement was the only realistic option, John walked me through 3 different options to consider, the considerations of each on performance and installation and said he would follow up with estimates later that evening (which he did). I green lit it that evening and John was able to come by the very next day and complete the job in a very timely manner and left the place spotless. I've found my new go-to plumber! read more

We replaced our tankless water heater because the old one was not maintained and did not keep the temperature. Great service and reasonable price. Also had a clog flushed out. Because of the location of the clog, it had to be accessed through the roof. read more

Great work honest and reliable. It's so good having a plumber you can trust and give you pros and cons for different plumbing choices. Had a whole home filter installed for my water. read more

John was prompt, professional, down to earth. We didn't have a big job, just draining a couple water lines and capping them off, but he was willing to swing by as a "walk in" appointment. You don't know how much you need a quality plumber until you NEED one. And John came through in spades. Thank you! read more

I've worked with John a few times now over the last few years. He's prompt, professional, gets the job done right, and you just know you are in good hands when he's on the job. Super glad to have found R.J. on Yelp, always good to have a great pro to call when you need the help. Thanks read more

My water heater broke and we were desperate for some hot water. RJ Plumbing to the rescue! I reached out on Sunday and we had a brand new water heater and recirculating pump on Tuesday. Our water heater is a weird style, one that is not available at the big box stores, so it took a technician with specialized knowledge to complete the job. RJ Plumbing had the knowledge, they were honest, and efficient. Thank you. read more

Echoing all the review, RJ Plumbing is the real deal! I called John in the afternoon due to a suddenly broken water heater. He came by the same day, and very quickly diagnosed the problem. Being it was an older heater the best move was to replace, and by the next day he had a new heater in place. It was great to finally enjoy hot water again. He is knowledgeable, professional, and very personable. I would give the highest recommendations! Thank you read more

John did a very good job installing a pressure regulator and leak sensor on our water line. I definitely recommend him. The missing 5th star is due to communication - it was difficult to get a hold of John while we were discussing the project. read more

R.J. Plumbing has helped me with so many plumbing problems in the past year or two, let me list them. Water was backing up in my garage basin making it hard to do laundry, but R.J. Plumbing figured out the problem and for a reasonable cost was able to run a new sewer line that has made my laundry chores so much more bearable. The kitchen sink stop making a gurgling noise too! My insurance company wanted me to have a leak detector and automatic shutoff installed and R.J. Plumbing was able to do it for me without a long wait. They have replaced leaking bathroom faucet handles too. I trust R.J. Plumbing because they get the job done right the first time, the pricing is very clear and fair, and once you find a tradesman with high integrity and competence, there is no need to call anyone else. read more

He was reliable, easy to communicate with and on time. His rates were very reasonable.

Professional, skilled and experienced with fair prices. John is meticulous and there are no surprises. We recommend!

John is a rockstar! Very responsive, reasonably priced and quick turn around. He answered my questions promptly and was able to squeeze in the appointment in the same week. Look no further if you need your water heater replaced. Highly recommend. read more

Replace broken p-trap under bathroom sink and connect to vent pipe and faucet. Arrived on time. Knew exactly what fix required and consulted with me on possible fixes. He had all supplies required to do repairs. Never left to fetch missing supplies or tools. Enlarged hole in plaster wall. Kept the hole at minimal size. Tested for leaks. Vacuumed dust and small chunks. Put large plaster pieces and old pipes in wastebasket . Presented invoice with reasonable amount within original estimate based on photo. read more

Finally! Someone with integrity, skill, manners, and a reasonable rate. He's old school, highly skilled, and very smart. I had a parade of plumbers over the years - none of whom could fix the issues I had paid them to fix. John fixed all of them in an hour because he understood (vs. guessed) the root cause. He also did my tankless water heater replacement fast and flawlessly. 100% + satisfied. Do yourself a favor and stop looking around. John is the best. read more

Just had a water softener installed and a tankless water heater a few years back. Both experiences were very easy and the work was excellent. Highly recommend. read more

We had John install a new tankless water heater. He was prompt, honest, and the work was brilliant. He took are of the old water heater tank which was a big relief as I would not know how to get rid of it. With critical work like this, you need someone you can trust. John is definitely that person and I am so glad he helped me with this work. Thank you!!!! read more

John was quick to respond and thorough with his explanations. Thank you. I'm bookmarking them for all my future plumbing needs. If you're in the south bay, don't look elsewhere. Hire only licensed contractors! read more

Don't hesitate to hire John Allen/RJ Plumbing. His wealth of experience and his expertise are comforting. I get that everything has gone up in price over the years, so while a quote may not sound cheap, if you check around, you'll find it to be very fair. He needed to get to a gas line underground and recommended for us to do the digging if we could. He said it saved us several hundred dollars. John had to replace part of the gas line, a shut off valve and a 40 gal gas water heater. He really does nice clean work. No more gas leak and plenty of hot water! He is a true professional, a decent, hard-working and honest man who did a great job for us. read more

John and RJ Plumbing is not just the best plumber, but probably the best contractor of any type that I have worked with since first becoming a home owner in 2002. I'd give them 6 stars, if I could. I called about five plumbers to help re-build my tub drain and trap. Four came for an estimate, but just three actually provided an estimate. My house is on a slab, and two of them wanted to jack hammer the slab under my bathroom to get at the drain. It would also mean that I would have to find new 12" tiles, which would never match. John took a little extra time to analyze how the original drain was constructed and came up with a much faster and much less expensive solution. I awarded the job on the spot. The key is EXPERIENCE. Other plumbers will send out a newer technician or a sales person to provide your estimate. As the owner, John has the experience to see the most options and provide the best solution. Fortunately, he also does his own estimates. He arrived on time, worked with limited access and finished on time and on budget. The work was elegant and completed with a high level of craftsmanship (see photo). Amazing and wonderful. For your next plumbing project, feel free to get additional bids if you like, but make sure that one of them is from RJ. Even with just one job completed, I have a high level trust with RJ Plumbing. read more

R.J. Plumbing is a one man shop. John is honest, personable, on time, prices are reasonable, and last but not least, he's a really good plumber. We plan to use his services in the future. He gets booked up so plan ahead. He doesn't do emergency calls. read more

I wanted to descale my water heater and reached out to 3 different companies for a quote. R.J. Plumbing offered the best rate. Due to a scheduling mix-up I went with a different company, but John was incredibly understanding and professional about the situation. When I need work done in the future I will contact R.J. Plumbing. John is straightforward and does not try to fleece you. read more

After having some unpleasant experiences with plumbers in the past we found RJ on yelp and decided to give them a try. We have had issues ranging from clogged drains to a leaky water heater and they have come through for us every time. The owner John is friendly, punctual and a great communicator. So glad we found them! I now recommend them to all of our family and friends. read more

I had the best experience with John and R.J. plumbing. John is incredibly genuine, honest, and reliable. This was evident in every single one of my interactions with him. He is knowledgeable, patient, and he knows what he is doing, and most importantly, he is fair. John is now my go-to for any plumbing matter. If i could give 10 stars I would! read more

John is the best! Call up RJ Plumbing for all your plumbing needs. I recently got the tankless water heater descaled by him and it's running great! Since we have hard water here in South Bay, it's a good idea to have tankless water heaters serviced annually to clean out all the calcium build up. Easy to make an appointment, very reasonable pricing, punctual, professional and honest. Highly recommend~ read more

Had to reroute a gas line and he came in with a fair price and completed in timely manner. Will use again for plumbing issues.

I sadly write this review due to the repeated non-response of John and RJ Plumbing, both this year and last. Most recently I left a message describing services needed early yesterday morning via both his preferred text and the listed office phone to address. I had three plumbing issues at my home: drain stoppers, a leaky faucet base, and replacing a kitchen faucet. He has not responded via text or phone. The same thing happened about a year ago or so; I chalked it up to Covid, but maybe not. To be fair, I'd used John in the past; he was excellent, fair-priced, and efficient, even answering questions about what I'd need to do to maintain his new repairs. I'm sorry that he has become non-responsive. read more

Our 75 gallon water heater began to leak a couple weeks ago so I started calling around to get estimates for a replacement. I got about 5 estimates and a couple were similarly priced including RJ's and the others were way over priced (30-40% over). I went with John at RJ because he was responsive, knowledgeable and came across honest. He came on time and completed the job quickly and neatly. He helped me subsequently troubleshoot a small problem with the hot water faucet and was super responsive. John at RJ is definitely at the top of my list for plumbers to call when I have any issues. read more

Thanks to Yelp, I've found an awesome new plumber. Backstory: For several years I've been using a plumbing service that drove a distance to get to my area. I liked that they were avail 24/7 (and I did have emergencies) but the older, experienced guys I've worked with are no longer there. So I went to Yelp searching for a local plumber, hopefully a small family-owned company. R.J. had 5-star reviews up the wazoo. John works alone & I like that. You can't call him at 2am on a weekend so know where your main water shut-off is, just in case. My immediate problem was declining water pressure/volume as I tried to water landscaping the past couple weeks. I disabled all the sprinklers a few years back during the drought & discovered it's more efficient to water by hand, although very time-consuming. So there I was recently, with water exiting hoses like a limp noodle as I stood in the blazing sun ready to tear my hair out by its bleached blond roots. A pressure regulator is a good idea (so your pipes don't blow up) & I always have one installed wherever I live. I suspected mine might need adjustment & I was right. John increased the pressure. Meanwhile, I learned about water volume - different from pressure. To increase the volume I need to get the water dept. out to change the meter - my next task. John had some great ideas to make my watering experience easier, like adding a hose bib, etc. & I will consider his suggestions. But for now I'm back in business with the hoses & the interior faucets are functioning more like normal. And John is wonderful. I learned so much. And he was kind to my cat who was in his face as we checked out an ancient toilet in the bathroom. As long as I'm on the subject of water: I have a big two-tiered concrete fountain in my back yard that doesn't work & leaks but is too heavy to move so the previous owner left it here & I fill it daily to use as a bird bath. The birds not only drink from it but they congregate on it. I see at least 3 different varieties of birds, chattering away, hanging out by the "pool". Like I should bring them a pitcher of margaritas & some sunscreen. Cat lazily watches the action from inside the house. Everybody's happy. H2O, yo, let it flow. read more

John was great in doing an affordable installation of a tankless water heater for us - job was on-time (he made time), the installation is super clean, and he was extremely timely. I've since called him for other plumbing needs and he is always responsive and has been able to work with my schedule. John is extremely responsive via yelp messenger as well as phone. he is definitely my go-to guy for any plumbing needs. read more

John was able to fix the shower valve and got us a new water heater installed. Good communication and great work!

John was amazing! He's the only plumber I've ever met who didn't try to up charge me just because I live in a nice neighborhood. He gave me the same quote as the last time we worked together, which rarely happens with other plumbers. He was quick, on time and super helpful. Honest guy. read more

John was quick to provide an estimate, priced our job very fairly, and completed the work quickly and efficiently. Would highly recommend him!! read more

John is responsive, knowledgeable, punctual, easy to communicate with. He replaced our water heater, made the process smooth and easy. Competitive price point. read more

John was professional, on time, and quick to install a water heater for us after giving us a quote which exactly matched what he charged us after doing the work. Highly recommend. read more

John is the epitome of what a real professional is!!! John is a great guy! He is someone that absolutely cares about your problems instead of how much money he is going to make. He came out to diagnose and fix my sink/faucet problem in no time. Thanks John!!! you're a Southbay National Treasure!!! read more

John was fantastic - got to us within a couple of days which I was not expecting (it was not an emergency). Fixed our toilet flush, snaked our kitchen sink and, in a return visit, bought and replaced the garbage disposal. Lovely to deal with, super straightforward and happy to explain things and give options. Everything is working great again! Highly recommend. read more

I've used yelp for reviews for a long time but hadn't felt strongly enough to write a review until now. It's time I give back. We hired RJ Plumbing to replace a water heater that was long overdue for replacement. It finally started leaking and we knew it was time. Reached out to various places. John was very professional in his communication, provided a reasonable estimate on both time to fix and cost, and stuck to both of them. He helped assess what needed to be done as a result of the leak which helped give us piece of mind on next steps. He actually showed up ahead of schedule and had quoted about 2 hours to swap it out but it took substantially less - I guess it was a relatively simple situation (water heater in garage with relatively easy access). I then asked about a bbq gas line that was incorrectly installed (hint: stay away from Fix All Plumbing who messed it up initially) and he gave me the information I needed to fix it myself instead of doing it himself which definitely saved me some money. I followed his instructions and was able to seamlessly fix it with $30 in parts. I find it rare to come across an honest plumber (several bad experiences), so it was refreshing to work with John. I'd hire him again in a heartbeat for the next issue we face. Thanks John! read more

I had a small plumbing job that needed to be done. His office called me back right away with a time for the work to be done. Not only did John show up on time, but he did all the work I needed very quickly and efficiently. He also showed me where the main water shut off was located on my new house and talked to me about additional work that needed to be done - not right away but he told me what to look for so I don't run into any problems. I was very happy with his estimates on the proposed work and the work completed. I will absolutely call them again with any new work I need. read more

Super quick response, reasonable estimate and quick appointment to replace my leaking water heater. Recently lost my great plumber and am thrilled to have this very capable replacement. read more

These guys are amazing! John was the one that worked with me and he's very honest about my plumbing issues, instead of upselling me. I saved a lot of money and appreciate the help provided! You can trust these guys like I did. read more
