Very pleased with R&R's services. Richard promptly replied to my quote on Yelp. His price was reasonable compared to other businesses. He replied to my emails right away.

Great fast service, great communication! I would highly recommend them if you need backflow testing. The first time we used them, we had to replace a few parts costing a few hundred dollars.

We used them ever since. read more

These guys are great answered right away, came right out, and handled business all in an hour!

Fantastic service from quotation to completion! Richard really took the time to carefully study what the job required instead of just blindly sending a quotation. Once we had decided to move ahead with the project, they were able to put us in their schedule within the week. They arrived on time and got to working on the job straight away, finishing the installation within just a few hours! R&R Backflow is a company that is truly committed to not only their work, but also to their customers. Due to unforeseen circumstances, they had to do additional work that was not included in the initial quotation. We expected to see additional charges on the final invoice, but the invoice we received remained true to the original quote - not a penny more! Outstanding quality of work, outstanding customer service. Do yourself a favor and call this company. They will definitely be our go-to guys from here on out! read more

Richard is a genuine and honest expert in the back flow testing business, but he can also replace pressure regulators and shut off valves. He came out to our company to inspect a leak at a union outside but we eventually had to replace the pressure regulator. Richard did such a great job for our company, that I contacted him for another job at my house. I had a small leak at the main shut off valve leading to the sprinkler system. The previous owner did not do a good job and used multiple fittings pieced together. Richard came out and pin pointed potential problems and gave me options on what I could do. Since it was original valve and pressure regulator, I had Richard do a clean rebuild with all new parts, fittings and valves from the ground to the building. The installation was super clean and professional looking. The connection are all the right sizes and now I have peace of mind. He did a great job for our company and at my house that I would use him for future issues. I would highly recommend Richard. read more

I called for a Sunday afternoon service because of the Backflow leak. Richard came and surprised me with a bill of $385 for a 5 minute service. Basically the screw was loose. I thought it was highly overcharge and he didnot give me an estimate. When I asked why it's so expensive , He said normally he charges $685 for Sunday. Wow. So expensive. Other plumber charges $89 for Backflow testing/service charge. Please be careful !!!!! read more

Had Richard come down for my company annual backflow device test that had failed. He gave me a speedy quote and fixed everything promptly. Very honest guy to work with and good honest prices! Will keep using him from now on for my plumbing and backflow needs! Thanks!! read more

I needed my backflow prevention test done as soon as possible and called many companies to see who can come out the earliest, and Richard was kind enough to empty out his busy schedule to come out in matter of 2 days. Super thankful he was able to squeeze in his time for me. Richard and Mondo (I'm sorry if I spelled your name wrong) came out for the backflow testing and wow, they were a good team. I'm all about efficiency, and they knew how to work well & fast. They were both nice and friendly, and one thing good about Richard and his team is that if anything goes wrong with the backflow prevention test, he makes sure he has all the materials to fix it on the spot so he doesn't have to make that extra trip to buy the parts to fix the problem. He will save your time and money, so I recommend hiring him!! I'll be definitely be referring him to my neighbors. read more

Richard is real and genuine expert in the Backflow testing business. Highly recommended !!! My church has a little complicated backflow device. I found a business in orange county and called. It was 2nd visit to test. Last year there was no problem. At this time, he said our device was failed and sent an estimate price to fix for $950. I contacted Richard to have some advise. Before he came to my church, he called the water company and researched the backflow device in detail. When he visited my church, he re-tested the device then figured out the previous tester did something wrong. Thank you so much, Richard !! read more

R&R Backflow deserves more than 5 stars! They are professional, knowledgable, reliable, and a pleasure to do business with. They communicate clearly and promptly answering telephone calls and E-Mails. I dealt with Richard, the owner, and he always promptly answered my questions in dealing with a somewhat complicated back flow issue. He always communicated with me promptly and clearly. He quickly had his technician test and resolve a back flow device and kept me involved in updates throughout the entire process. Richard is very knowledgable as he apparently worked for a major city and was in charge of the back flow testing and compliance on the city side so he has a wealth of invaluable knowledge. I will definitely use R&R Backflow for my annual testing and future repairs! It's a true pleasure doing business with such a highly professional and reliable organization. read more

I contacted Richard on Friday after being informed from a different Backflow Testing Company that my routine annual Backflow Testing failed. Instead of just paying for the repairs, I decided to get a second opinion since the other company didn't send me a detailed proposal of the repairs to be done. Luckily I found Richard on yelp and sent him a message and he responded within minutes! He even said that he could come out the very next day! Well he DID come out the very next day and performed the test, which did fail, HOWEVER, it passed after a simple cleaning! No repairs had to be done or parts replaced! Richard is very professional and honest and I will be using him every year going forward and recommending him to everyone I know! -KD read more

I definitely recommend and will use them again in the future. read more
