Central O Plumbing

Central O Plumbing handles plumbing work in Hayward. Jose shows up for water heater repairs under warranty, tankless system installs, sewer line clogs, and shower valve fixes. Customers reach them after parts arrive from manufacturers or when existing systems stop working right. The company takes on calls for Rheem units with error lights, overflowed cleanouts after storms, and temperature controls that customers tried fixing themselves first.

Jose handled a warranty part swap on a water heater and walked a homeowner and trainer through every diagnostic step before finishing the job. A week later the same customer called again when a sewer cleanout backed up, so he brought heavy equipment to clear the line and ran a camera to show what was inside. Another call came in for a shower that stayed the wrong temperature; he talked the homeowner through the needed parts over the phone, then came the same day to finish the repair in short order. Tankless installs also get done with clear arrival times and a follow-up visit to confirm everything runs as expected.

Response stays quick once the call comes in, with updates on when the truck will arrive and straight talk on what the house needs. Pricing stays reasonable with nothing added later, and the crew explains options without pushing extra work. They cover calls inside Hayward and nearby spots, often fitting in same-day slots when parts are already on site. Communication stays direct from the first message through the final check.

Reviewers keep noting the same points across jobs: clear explanations, fair costs, and solid results on water heaters and drain lines alike. The company holds a Google rating of 4.9 from 121 reviews. DIRT Score 4.7 from 121 reviews on Finds.

“My hot showers had become luke-warm almost cold 🥶. I checked my Rheem water heater and the blue light was now a red flashing 7 times. I called Rheem and luckily the water heater was still under parts warranty 😉. They said they would send the parts. I asked, “Who is going to install them?” I was told I would have to find a plumber to install the parts😳. I was sent a list of plumbers but before I received the list, I called the company that installed the water heater. They said it would be about $400 to come out when the parts arrived and then I would be charged hourly (2 hours minimum) 🤨. When the parts came, I checked the list Rheem sent, I called JC Plumbing and Rooter and left a message. Jose promptly texted me back and gave me a quote for the repair (one price) and it was very reasonable 🥳. The day of the repair, Jose kept me up to date on his arrival time as he completed other jobs. He and his team came in and got to work (professional, friendly, and insisted on wearing booties over their shoes). They finished within an hour. And since I had a plumber in the house 😬, I asked if he could take a look at the tub drain (my repair wasn’t working). He did and made a quick correction to my attempt and the issue was fixed. I will call JC Plumbing and Rooter for any plumbing issues I have going forward. If you are looking for a good, honest plumber, give Jose a call. I’m glad I did 😊!”

“Amazing service! Came out on a warranty call when the water heater went out. Very quick to get us on the schedule; great communication and really helpful trouble shooting some stuff over the phone with me. Highly recommend”

“I could not be more impressed with Jose. He’s responsive, thorough, knowledgeable, and reasonably priced. I first worked with him on a warranty call to replace part of my water heater that the company had provided. He came with a trainer and patiently talked both of us through his diagnostics and replacement steps. Then, a week later when we noticed our sewer clean out had overflowed in the wake of recent storms, he came out and used some pretty powerful tools to first clear the clog and then to run a camera through the pipes to help us both understand our system. He took several photos along the way and was eager to explain everything he saw and answer all my questions. Throughout, and in a detailed follow up invoice/summary, he gave specific advice on how to follow up with our builder and the city when we encountered items they should address. I will not hesitate to contact him again with the next plumbing/sewer related issue. He’s a model for all tradesmen—trustworthy, a genuine teacher, and a pleasure to work with.”

“Needed assistance with my shower, the water temperature wasn't adjusting. I tried to DIY via YouTube but I was missing a tool. I looked for a plumber in Hayward and so glad I found JC plumbing. He not only talked me through the repair, he was patient in helping me identify the parts and tool I would need. I decided I wouldn't DIY it and thankfully he was able to take me the same day! The repair was quick, the price was fair, and I felt pleased with the work and future recommendations! I give them 5 stars!”

“Highly recommend JC Plumbing for tankless water heater installs! He arrived promptly and gave me accurate ETAs prior to arrival on day of installation. No hidden costs or additional costs came up. Fair price for excellent work. Very professional with explaining my options and what suited my house needs for a tankless system. He came back a week later to patch up part of the area he worked on and checked if everything was working as advertised. A+++”
