    Before: Old PRV Valve
    Mark M.

    Found RJB Plumbing on Yelp today, having a 5.0 star rating and 140+ reviews I felt pretty comfortable contacting them. I contacted them through Yelp and got a response within minutes. I needed my Pressure Regulating Valve replaced, they sent a quote and offered to be out in 45 minutes if needed. We agreed on the price and Bob came out and did the work, super nice guy, lives the next neighborhood over! He explained exactly what and how he was going to do the replacement and even got me a double union PRV so that next time I could literally replace it myself in about 30 minutes! (as long as I got the exact same model). He even left the area cleaner than he found it! I won't hesitate to call RJB Plumbing if I have any plumbing needs in the future. 5 Stars all the way!

    Bob saved the day. To start, he talked me through the mistake I made when striking my main water line. Since it was late in the day on the weekend, Bob was able to schedule me the next work day and he fixed the issue. And, he really is a nice guy and knows his stuff! 100% recommended!

    Whole house filtration system installed by Bob.

    Bob takes pride in his work, and it definitely shows. He is detail oriented and has incredible expertise to help. In my case, he was able to re-pipe all the exposed copper pipes in my attic with PEX. He also installed a whole house, water filtration system, and a Moen valve that detects leaks. As you can see, the quality of his work shows with beautiful copper welds, and neat plumbing.

    Nice work by Bob!

    Amazing job and I'm a happy customer! Our water heater broke and first thing I did was to go to yelp to find someone to fix it. We never had plumbing issues until this incident so a plumber is not on our phone books. I saw the reliable reviews from RJB plumbing among others. But what stood out was that Bob was the business owner who directly responded and came out to look at the issue. I'd rather have to deal with one person all the way through than a receptionist who sends a random plumber to my house.The other thing is he's open 24/7 and he said I could call him whenever if there's an emergency! That's really reassuring! Also he's in San Marcos, close to where I live. As for his service, he was patient, knowledgeable and helpful. He responds quickly on Yelp and via text. He came in a very short time to provide us a free estimate and arrived on time the next morning for the heater replacement. He swept the floor, cleaned the area, installed the tank securely, stored away the warranty documents neatly, wore shoe covers in the house - professional! I felt safe to leave him do his own thing, and not having to watch over him. He also charged a very reasonable price. I also wanted to replace the whole shower and arm and he went to Home Depot right away to get it done for me after the heater was finished. We're very very happy with his work and professionalism. Highly recommended!

    Brought my sink/faucet install up to the code...I am super happy and grateful!

    Can I send you a photo?

    Yes

    SDGE said the valve in our patio fire pit is leaking gas. Can you do those repairs?

    Yes we can replace valves or pip but sometimes that would require opening up potentially the wall to get access to it

He was also very impressive when listening to him explain what our system could look like and what our options would be. At that time, we were already having an ADU built in our backyard, and when the contractor found out we wanted a new tankless heater and water filter installed on our main house, he offered us a discount and installed a tankless heater. It ended up being a big mistake as they did a very sloppy job. Fast forward to this past September 2025, and my wife put out a Yelp request to get a water filtration system installed. She did not know that Pure Plumbing had come out previously, but I recognized Bryan's name when my wife told me he would be coming to the house. He walked my wife through everything while I was at work, and she was impressed by him too. He even pointed out where our contractor's plumber had made a major mistake with our tankless heater. We ended up having Pure Plumbing install the water filtration system, the price was great, and they did a fabulous job. In addition, thanks to Bryan's alertness, we were able to have our contractor's plumber come out to fix their mistake. Thank you Bryan, and thank you Pure Plumbing. I highly recommend this company.

    I know I'm just piling on with this review, but my experience was quick, painless and educational…read more My guy was on time for our appointment and went right to work. He flushed/de-scaled my tankless water heater and then made sure everything in the house was working as it should. The whole job was done in less than an hour and his recommendation for me was not to worry about it for another two years. So if I only have to spend $125/year for my water heater maintenance, I'm probably getting away cheap. great service, I'll use them again. Oh and if you call to make an appointment you will be connected to "Sophie" at first, just to warn you, she is AI and gets stuff wrong, best thing you can do is ask her if she's AI, she will tell you she is, and then you can ask for a human being, worked for me. TIP TO OWNER - make sure you stock up the True Plumbing stickers in each repairperson's van, having a sticker on my water heater will help me in two years time. My guy had run out.

Was confused because took my name and booked an appointment, but didn't get my address. 2 hour window for the appointment and was able to get a time less than 48 hours. Received a confirmation email and had my address which was wild. Fast forward to Monday and they arrived 25 minutes before their scheduled time. They sent a text that they would be arriving in 30 minutes and then they were there. Usually would be happy for a plumber to arrive early, but wife had a work call and I was driving home from work to meet him. He was ringing the doorbell a bunch which annoyed my wife, but life happens. Joel was very nice and said we needed to call CPL to locate where exactly the leak is. He gave me the wrong number for CPL even though I read the number back to him. True Plumbing didn't have any appointments the next day, but Joel found a way to squeeze me in to take a look after CPL completed their inspection. Sent two estimates which I had questions about. I talked to Joel on the phone and he answered them all. I really like that he was able to do cement work which some places wouldn't do. The communication across the board really stood out to me and I know their prices are better than most because I had quite a few estimates.
