Company Overview

Established in 1956, R.K. Knight Plumbing is a family-operated company based in Whittier, CA. Our plumbing services encompass drain repair, trenchless drain repair, drain cleaning, hydro-jetting, plumbing fixture repair, commercial plumbing, water heaters, water lines, gas lines, and trenchless installations for both water and gas mains, among other services!

Ronald Knight Sr. began his plumbing career in 1947, focusing on new construction projects in the Los Angeles and Palm Springs regions. In 1956, he made the decision to establish his own company, R.K. Knight Plumbing. In 1980, Ronald Knight Jr., Sr.'s son, chose to follow in his father's footsteps and joined the family business. Sr. devoted many years to his family and work before he passed away in 2007. Today, Ronald Jr. is supported by his two eldest sons, Ronnie III and Randy, to uphold this family legacy. Ronnie III serves as the general manager, while Randy is one of our skilled technicians. Delia, our office manager, along with technicians Shawn and Memo, complete our family-oriented team.

I took over this business from my father, who succeeded his father. I enjoy going to work, meeting new people, and hearing their unique stories. I find it fulfilling to solve unexpected problems for others. On top of that, meeting someone who knew me as a young child working with my grandpa is a rare experience. I realized that my father and grandfather held great respect in our community and the plumbing field, and I aimed to attain that same honor.

First time using R.K Knight plumbing and will definitely be using them again. Memo came out to flush my tankless water heater and he did a wonderful job. Showed up on time, very reliable, knowledgeable, and super nice gentleman. He answered every question I asked him and explained everything thoroughly. I wouldn't hesitate to call R.K. Knight Plumbing and ask for Memo if I ever need any assistance with plumbing. Thank you again for all your help Memo!

Top level service! Friendly and professional. I always feel he comes in with a ""how can I help?"" attitude. He does great work at a fair price. My first choice when I need plumbing service.

We had Memo out to flush out our water heater and look at our low water pressure. He was informative, thorough, and very knowledgeable. He arrived at the scheduled time, kept us updated as he diagnosed our issues, and even found and fixed another problem with a leaky toilet while he was here. Our water is hotter and better than it has been since we moved into this house 3 year ago! We are very happy with the level of service and honesty of Memo and feel that the price was very reasonable. RK Knight Plumbing will now be our preferred plumber!

We called RK Plumbing because we needed to have our washing machine valves replaced. We were so happy when we heard someone could come out today. They sent us ""Memo""within about 40 min.! Memo was extremely professional & polite. We really appreciated how well he explained everything to us & even provided us with various options. Memo got the job done quickly & at a reasonable cost. Thank you Memo !

I was so happy when Art suggested a Hydro jetting might fix the ongoing problem I've had with toilet back ups. After showing me the camera image of the narrowed pipes, I knew this was the right thing to do. Art came today to do the procedure. They were clean, fast and explained everything before, during and after. Seeing the difference in my pipes with their camera was just amazing. I think that technology is just fantastic. I am very pleased with his expertise!

Memo came to our home for a sewer line blockage and saved the day! Clear estimates and options given before work began to avoid cost surprises. Installed a cleanout pipe for any future issues. Thanks Memo!

I can't believe the quick response I got from RK Knight. I called about a backed up sink and they sent someone to my house in about 30 minutes. Shawn did a great job! He figured out the best way to snake the clog and cleared the drain quickly. I appreciate the quick response from RK Knight Plumbing and the professional service from their technician, Shawn. RK Knight is now my go to plumbing company.

Art did a great job and gave a thorough explanation of what our situation was. He arrived earlier than expected and also let us know in advance that he had availability to arrive early which was great. Super amiable, thorough, and fixed the issue we were having quickly. Would definitely recommend RK Knight to anyone in the area and will definitely be reaching out to them again if needed (hopefully not) for plumbing issues in the future!

Not to mention, cost of service was definitely reasonable and worth the $. A staple and go-to plumbing service without a doubt!

We can't say enough good things about these guys. Super great customer service. Diagnosed and fixed our shower leak very fast and very thorough. Great, honest pricing. We've used them before for another (bigger) job and they were fantastic then (better price and quicker repair than two other quoted plumbers). We recommend them to all of our friends and family in the area. Shout out for Memo (who did our last repair)!
