Keep your endless hot water flowing with expert tankless water heater repair in Chula Vista.
At LGE Prime Plumbing, we specialize in diagnosing and fixing tankless systems so you don’t have to deal with cold showers or inconsistent hot water.
Tankless systems are built to last, but like any appliance, they can run into issues — especially in areas like Chula Vista where hard water and coastal air can impact performance. Our licensed plumbers repair problems such as:
Mineral buildup from hard water that reduces efficiency
Fluctuating water temperatures or lukewarm water
Error codes and ignition issues with gas units
Low water pressure connected to your tankless system
Blocked exhaust vents or ventilation problems
If your tankless unit is beyond repair, we also offer full water heater replacement in Chula Vista with both tank and tankless options.
Our tankless water heater repair specialists in Chula Vista will restore your system fast — so you can get back to comfort.

Since 2010, we’ve been trusted by homeowners in Eastlake, Rolling Hills Ranch, San Miguel Ranch, and Bella Lago for reliable tankless water heater repairs. We understand the unique plumbing challenges of Chula Vista homes, from water quality to local building codes.
Our technicians arrive on time, diagnose issues quickly, and provide upfront repair options so you can make the best decision for your home.
When your tankless water heater isn’t performing like it should, trust our experienced team to get it back in shape. And when you need a reliable Chula Vista plumber for other home or business plumbing projects, you can count on us for the same quality service.
Not sure if you need a repair or a replacement? Here’s a quick guide:
Repair makes sense if: your system is under 10 years old, the issue is minor (sensor, valve, descaling), or the cost is much lower than replacement.
Replacement may be better if: your system is over 12–15 years old, repairs are frequent, or efficiency has dropped significantly.
If your unit has reached the end of its lifespan, we’ll guide you through the process of selecting the right system and handling a seamless water heater replacement in Chula Vista.

Our tankless water heater stopped working right before the weekend, and with three kids, we were in trouble. LGE Prime Plumbing showed up quickly, diagnosed the issue, and had us back to hot showers in no time. As Eastlake residents, it’s a relief to know we have a reliable Chula Vista plumber we can call whenever something goes wrong.

Thought I would have to replace my entire system, but the team explained that a repair was all I needed for now. They were honest about the options and saved me money. It’s rare to find that level of service these days. I highly recommend them for anyone in Chula Vista dealing with tankless water heater problems.

Owning a condo near Rancho del Rey means space is tight, so we went with a tankless system years ago. When it started acting up, LGE Prime Plumbing knew exactly how to fix it. Professional, on time, and respectful of my home — they’ve definitely earned my trust as my go-to Chula Vista plumber.
