"The plumber spent a lot of time just trying to figure out the source of the hidden leak. He had a lot of patience. The quality of work was good as was the price. I would definitely hire them again."

"Jose (with JRC Plumbing) did an excellent job replacing my kitchen faucet. He quickly responded to my request and was on time to the job site. He was clean and effecient (everything you hope for in a plumber inside your home)! His attention to the details (making sure the faucet was centered and no smudges) was definately appreciated. I highly recommend Jose for your next job!"

"I had a break in my water main, leaking about a half-gallon per minute (720 gallons/day). By the time the water company inspector left, it was almost noon and I still had to find a plumber. Do It Right Plumbers scheduled me for immediate service, and Dakota was at my home that same afternoon. He restored the water service to my home, while bypassing the water main. This stopped the leak and allowed me and my family to go on with our day as if there was no water main problem. He explained my options and gave me exact prices. A lot of digging was needed, there were complications, and extra labor and hours were needed because the burst pipe was underneath the sidewalk. All of the dirt was shoveled on to protective tarps. When the water needed to be shut off, the down times were really brief. When everything was done, Dakota had not only replaced the water main, but also the water pressure regulator, the hose faucet, and all of the connections and valves. Then he replaced all of the dirt, re-planted the shrubs that had been removed during the job, and left the area looking as if nothing had happened. As for the final price, it was very fair, and exactly as he had quoted---not a penny more! I had a water main break before, and I remember how disruptive, expensive and stressful the last job was. Dakota really took a lot of the pain out of this latest ordeal. As hard as Dakota worked on the job, he worked equally hard to make this job as easy on me and my family as possible. If any future plumbing needs arise, I will be calling Do It Right Plumbers."

"HomeX technician Eddie replaced a broken water shut off valve in the bathroom & installed a replacement kitchen faucet. He was knowledgeable, friendly, efficient & responded to my emergency call within the hour. The HomeX office & dispatcher were very friendly & helpful. This is the second time HomeX has come to my rescue to take care of my plumbing problems. I will definitely call them next time I need a plumber."

"We had a great experience with GG’s Plumbing at our cabin in Lake Arrowhead. We originally hired them to install a whole-house water shut-off system, and the job was done quickly and professionally. While they were there, the team noticed that our pipes weren’t properly insulated — something that can obviously become a real issue in the mountains during winter. What I appreciated most was their approach: they didn’t pressure us at all. They simply explained the risk, gave us the option to fix it now or later, and let us decide. That kind of honesty goes a long way. We chose to go ahead and have the insulation done, and I’m glad we did. Their team was easy to work with, the communication (mostly through text) was fast and clear, and everything was handled smoothly. Reliable, knowledgeable, and straightforward — I would absolutely recommend GG’s Plumbing."

FAQs for plumbing projects in Walnut, CA

It depends on the severity of the leak. Minor leaks may not require immediate attention and can be scheduled during regular business hours. However, if the leak is causing significant water damage or you can't control the flow of water, it's best to call an emergency plumber right away. Addressing serious leaks promptly can prevent structural damage and mold growth, potentially saving you money on extensive repairs later.

A journeyperson plumber is a licensed professional with a state-issued permit who installs and repairs piping for water and heating systems under the supervision of a master plumber. They have completed extensive training and amassed significant experience leading teams, drafting blueprints, and designing comprehensive plumbing installations. Their proven expertise ensures that they can handle both routine repairs and complex projects with precision.
