What are common signs my tankless water heater needs repair?

Common signs include fluctuating water temperature, lukewarm or no hot water, error codes on the unit, strange noises, or the unit shutting off during a shower. If you notice any of these, it is smart to schedule a diagnostic before the problem worsens.

Can you repair any brand of tankless water heater?

Yes. Omaha Drain services most major tankless brands installed in the Omaha metro, including gas and electric units. Our technicians are trained to read manufacturer error codes, test components, and bring your system back to peak performance whenever repairable.

How often should a tankless water heater be flushed or descaled?

In areas with hard water like the Omaha metro, most manufacturers recommend a professional flush and descaling once a year. This helps remove mineral buildup, protects the heat exchanger, and keeps your tankless running efficiently.

Yes. If your tankless quits in the middle of a busy day, we offer same-day and emergency appointments in many cases. Our team will stabilize the situation, get you hot water as quickly as possible, and provide clear repair options before any work begins.

Will you give pricing before you start work?

Absolutely. We perform a diagnostic, explain what we find in plain language, and present clear options with upfront pricing before any work starts. You choose the option that fits your home and budget and there are no surprise add-ons at the end.

The Problem

Cold Showers, Error Codes, and a Family Waiting on Hot Water.

When your tankless water heater stops doing its one job, everything grinds to a halt. Showers get cut short, dishes pile up, and you are stuck staring at a blinking error code while the water stays ice cold.

Water temperature swings from scalding to freezing mid-shower.
Error codes flashing on the unit with no clear explanation.
Unit shuts off randomly or struggles to keep up with demand.
Mineral buildup and hard water scale slowly choking performance.

Why It Matters

Why Tankless Water Heater Maintenance & Repair Is Essential.

Tankless water heaters can last for years, but only if they are maintained and repaired correctly. Ignoring small issues can turn into major breakdowns, expensive replacements, or even safety concerns.

Protect Your Investment

You spent good money on an efficient tankless system. Regular maintenance and proper repairs help you get the full life out of it instead of replacing it years early.

Prevent Surprise Breakdowns

Flushing, descaling, and inspecting components catch small issues before they leave your family without hot water on the coldest day of the year.

Maintain Efficiency & Warranty

Many manufacturers require annual service in hard-water areas to keep warranties valid. We follow those guidelines so your system stays efficient and protected.

How Tankless Systems Work

What Is Happening Inside Your Tankless — and Where Things Go Wrong.

Instead of storing hot water in a tank, your tankless unit heats water as it passes through a heat exchanger. When scale builds up or parts fail, that process breaks down.

1

Cold Water In

Water flows through the inlet filter and into the heat exchanger. Hard water can clog strainers and reduce flow before it even reaches the heating components.

2

Heat Exchanger

Burners or elements rapidly heat the water. Scale buildup here is the #1 enemy of tankless systems, causing error codes, noise, and premature failure.

3

Sensors & Controls

Flow sensors, temperature sensors, and safety switches constantly check performance. When a sensor misreads or fails, the unit often shuts itself down.
