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

Gomez Sewer and Drain handles tankless water heater installation for homes throughout San Jose and the surrounding communities of Campbell, Los Gatos, Palo Alto, Santa Clara, and Sunnyvale. We assess your home's gas line capacity, venting setup, and water pressure before any work begins. San Jose's water supply carries moderate to high mineral content, which affects how a tankless system performs over time. We account for that during sizing and setup so your unit runs efficiently from day one. Converting from a storage tank to a tankless system often requires a dedicated gas line, new venting, and updated piping. Our team handles each of those steps to meet California Plumbing Code and local building requirements. If your home has a closed plumbing system, we check for proper pressure relief components as part of every installation. When the work is done, you get a wall-mounted unit that delivers hot water on demand and frees up floor space in your garage or utility area. Call Gomez Sewer and Drain to schedule your tankless water heater installation.

Santa Silva Google review · February 2026

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 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.
