Overview
Tankless water heaters heat water on demand as it moves through the system. When something interferes with that process, you may notice inconsistent temperatures, no hot water, error codes, or repeated shutdowns.
Purflo Plumbing provides tankless water heater repair for homes and businesses in Tucson, Arizona. We assess the unit and its connections to identify what is causing the problem, then explain the recommended repair before work begins.
Symptoms
Signs your tankless water heater needs attention
Water temperature keeps changing
Temperature changes can happen when water flow is inconsistent or the heater is not responding correctly. Testing the unit while water is running helps narrow down the cause.
Water takes too long to get hot
A delay may point to a flow or heating problem, especially when the issue is new. We check the heater and its connections to determine where the delay begins.
The unit is leaking
Water around the heater should not be ignored. The location of the leak helps determine whether the problem is at a connection or within the unit itself.
Our process
How tankless water heater repair works
-
Describe the problem
We start with the symptoms, when they occur, and whether the issue affects one fixture or the whole property. This gives the inspection a clear starting point.
-
Inspect the heater and connections
The unit, water lines, shutoff points, and visible connections are checked for signs of leakage, restricted flow, or an operating problem.
-
Identify the repair
After diagnosis, we explain what is causing the problem and what work is needed. If the issue is outside the heater, we point that out rather than treating the wrong component.
-
Test the result
Once the repair is completed, the system is operated again to check hot water delivery and confirm that the original symptom has been addressed.

Tankless Water Heater Repair questions
Answers before you book.
More questions on our full FAQ page.
Why is my tankless water heater not producing hot water?
Several issues can cause a tankless water heater to stop producing hot water, including flow problems, ignition issues, temperature controls, or a problem within the unit. Purflo Plumbing can diagnose the cause before recommending a repair.
Why does the water temperature keep changing?
Inconsistent temperatures can be caused by changes in water flow, temperature settings, or how the heater is operating. Purflo Plumbing can inspect the system to determine what is affecting the temperature.
Can a leaking tankless water heater be repaired?
It depends on the source of the leak. Leaking connections may be repairable, while a leak within the heater itself may require a different solution. We can identify the source before recommending the next step.
Should I keep using the heater if it is leaking?
If the unit is actively leaking, stop using it if you can do so safely and arrange for an inspection. Continuing to operate a leaking heater can lead to additional water damage or other problems.
Plumbing Problems Don't Always Wait
A leaking pipe, backed-up drain, or failed fixture can quickly turn into a bigger problem. If you can safely shut off the water, do so, then contact Purflo Plumbing so the issue can be assessed before more damage occurs.
