Company Overview

Since 1956, R.K. Knight Plumbing in Whittier, CA has proudly operated as a family-owned business. We offer a variety of plumbing services, including drain repair, trenchless drain repair, drain cleaning, hydro-jetting, plumbing fixture repair, commercial plumbing, water heaters, water lines, gas lines, trenchless installations for water and gas mains, and much more!

In 1947, Ronald Knight Sr. started his journey in plumbing, working on new construction in the L.A. and Palm Springs areas. In 1956, he decided to launch his own venture, founding R.K. Knight Plumbing. Following in his father's path, Ronald Knight Jr. joined the family business in 1980. Sr. devoted many years to his family and work before he passed away in 2007. Today, Ronald Jr. works alongside his two eldest sons, Ronnie III and Randy, to maintain this family heritage. As the general manager, Ronnie III oversees operations, and Randy is one of our expert technicians. Completing our family team are Delia, the office manager, and technicians Shawn and Memo.

I inherited this business from my dad, who took over from his own father. I love the opportunity to go to work, meet new individuals, and listen to their distinct 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.

Outstanding service from R K Knight Plumbing. On the phone Delia took great care to answer my questions and concerns completely and professionally. The technician, Josh, was outstanding in getting the problem fixed. He explained the cause and future steps to take to prevent it from happening again. Great work for a great price.

Ronnie and Randy. Two excellent, honest, hard-working, conscientious, brothers who came by to replace my water heater. It is obvious they know their craft. The work they leave is awesome and their pricing is very fair. Thank you again for your work!!

We very much appreciate RK Knight Plumbing and they are our plumber moving forward.

We had originally contacted this company because they are in Whittier and they had stellar reviews. But they were not available on the day I contacted them. Since we had a sewer issue and this home is a rental, I wanted to resolve it as quickly as possible for our tenants.

I contacted a different plumber in the area who was able to come out same day. Unfortunately, he not only was NOT able to resolve the matter, but he came up with a crazy list of stuff that didn't make sense and wanted thousands to do it, pressuring me with a panic tactic. I ended up pausing at this point in order to get a second opinion.

In the meantime, my husband contacted a buddy in the area and he said they knew the owners of RK really well and that they are who they recommend.

We contacted RK the following day, and they were able to get out there same day at this time. They immediately found the problem, and it was resolved within two hours.

They provided us with an estimate of adding a clean out at the front of the house for any future issues. The estimate provided was substantially less than the first plumber who wanted a fortune for a bunch of stuff that wasn't necessary.

We will be adding a clean out in the future to make any issues even easier to resolve.

They were professional, knowledgeable, polite, super nice and amazing. We will refer RK Plumbing every chance we get.

update Ron the owner came out Friday to try and fix my bathtub faucet he wanted to try and help me I do have a press in seats shower valves and he tried to grind down the seats and re install but still leaks he said it needs new seats which are very hard ti try and replace if you find them and if I decide to change out the unit it has to go through the outside walk stucco he referred me to an copper repipe that could do the job Ron at least tried to help me Thank you Ron I found the seats on line dont know when I'll receive it's just frustrating to know that something that should be simple turns into a major job because obsolete parts
