Expert Water Heater Installation in San Jose And Surrounding Areas, CA

Water heater installation in San Jose and the surrounding South Bay cities involves more than swapping one unit for another. At Gomez Sewer and Drain, we handle the full scope: removing your old unit, sizing the right replacement for your home, making all water and gas or electrical connections, and installing seismic strapping required under California code. Every city we serve, from Campbell and Santa Clara to Palo Alto and Sunnyvale, requires a plumbing permit before work begins. We pull that permit for you. San Jose's hard water is also a real factor here. Sediment buildup shortens the life of a water heater and reduces hot water output over time. We inspect supply lines, shutoff valves, and the T&P relief valve during every installation so nothing gets missed. Whether you are replacing a failing tank unit or upgrading to a tankless or heat pump system, we match the right solution to your home's existing plumbing, gas lines, and electrical panel. Call us to schedule your installation in San Jose or any of our surrounding service areas.

Our experience was terrific. We had a medium sized job: replace the 90 year old iron sewer connection out rom back of home, down the driveway and out to the property line, and add a BBQ island (sink, garbage disposal, gas appliances) in the back yard. All together about 150' of sewer plus venting for the BBQ island, and water, gas to the BBQ. All work was done with permits. The quote included connection to the sewer under the home (not just at the exterior foundation where other quotes specified). Communication was excellent. They arrived when they said they would. Both the principals and the workers are very good people. Work went quickly when not waiting on inspections (schedule inspections early!). I judge a firm by how they handle problems. In this case, the rough plumbing inspector gave the OK for a certain island venting technique. The different final inspector said it must be changed, and Gomez plumbing just fixed it promptly, all within the original quote. Of course we waited for a second final inspection before getting the project closed (schedule early!) Gomez is now our go-to plumber.

5/5 stars – I was very impressed with Gomez Sewer and Drain. Ivan & his entire crew are wonderful! They showed up on time as promised, squeezed me in next day on the schedule, handled the problem quickly & efficiently, cleaned up beautifully, and sent me the emailed invoice, all within 24 hours! I'm a realtor of 23 years and had a back up in a condo I'm selling. I had no time to waste and they came to my rescue quickly! They made me look good to my clients. I have them on speed dial and part of my trusted team. I highly recommend you put them on yours.

I was nervous about a clogged drain, but the team from Gomez Sewer and Drain showed up on time and were incredibly friendly and professional. They explained the problem, worked efficiently, and had my kitchen drain clean and flowing again in less than an hour. The plumber was courteous and answered all my questions about the repair, making me feel confident that the job was done right. I appreciate the timely service and will definitely call them again for any plumbing repair needs.

He patiently answers all my questions and clearly explains the work needed. Fidel’s pricing is fair and honest. I highly recommend Fidel!

I wanted to express my sincere gratitude to Fidel Gomez for his quick response and help! My daughter had a bit of a mishap by putting a toy down the toilet, and we were without a working toilet for nearly three months. A plumber came to fix it, but they initially suggested replacing the entire toilet. However, something just didn’t feel right, and I suspected the toy was still inside. To my surprise, when I called Fidel, there was a bubble bee inside! So, we owe him a huge thank you for his prompt assistance and for saving the day. He’s definitely my go-to plumber from now on.
