Straight Shooter Plumbing & Rooter repairs, replaces, and installs tank and tankless water heaters in Oak Ridge homes, including tankless repair for units showing error codes.
A tankless water heater that flashes an error code and shuts down is a different problem from a tank that has started leaking, and both are different from a household that has simply outgrown its heater. Straight Shooter Plumbing & Rooter handles all of it for Oak Ridge homes: repair of tank and tankless units, replacement, and new installation, with a straight answer about which one your situation calls for. Call (865) 761-8765 for a free estimate during normal business hours. $200 off tankless water heater installation is available in Tennessee; terms apply.
What is involved in tankless repair?
Tankless units heat water on demand as it flows through, so their problems tend to be about flow, ignition, and controls rather than a tank. The symptoms that bring in a tankless repair call:
- An error code on the display, often followed by a shutdown.
- Water that goes hot, then cold, then hot again during a shower.
- Fluctuating temperature when a second fixture is opened.
- Reduced flow of hot water over time.
- The unit cycling on and off, or failing to ignite.
Diagnosis looks at the unit's flow path, which can narrow with scale over time; the ignition and venting, where applicable; the sensors and controls that the error code points to; and the demand being placed on the unit. Some of these are repairs, some are maintenance such as descaling, and some are a sizing issue rather than a fault. The tankless water heaters page explains the technology; the technician explains what yours needs.
If your Oak Ridge water heater is doing any of this, call (865) 761-8765 or book online. Free estimates during normal business hours.
What is involved in tank repair?
Tank units store heated water, so their problems tend to be about heating components, sediment, and the tank itself:
A fault on a sound tank is a repair. Water from the tank body itself is not; that tank is done, and the conversation moves to replacement.
When does replacement or new installation come in?
Replacement is for a unit that has failed or is clearly worn: a tank leaking from its body, advanced corrosion, or a tankless unit whose repairs are no longer sensible. Replacement includes selecting the right type and size for the home and fitting it.
New installation is for adding a heater, relocating one, or serving a new part of the house, including placement, connections, and venting where applicable.
Both tank and tankless are available for replacement and installation. Which is right is a suitability question, and the honest answer is sometimes the one you did not expect.
| Symptom | Likely cause and path |
|---|---|
| Error code and shutdown on a tankless unit | Control, sensor, or flow issue; repair or maintenance |
| Hot, then cold, then hot | Flow response or a fault; diagnosis decides |
| No hot water from a tank | Element, thermostat, burner, or control; repair |
| Water from the tank body | Replacement |
| Rumbling or popping from a tank | Sediment; maintenance, or a sign the unit is aging |
When is tankless the wrong choice?
Tankless is a good fit for many homes and a poor fit for some, and a recommendation should say which. Factors that can make tankless the wrong choice:
- Peak demand the unit would have to meet exceeds what a sensible installation can deliver, for example several showers and appliances running together.
- Existing connections would need extensive changes to support a tankless unit, and the cost of those changes outweighs the benefit.
- Space and venting at the available location do not suit a tankless installation.
- The current tank is repairable and the household is well served by it.
When any of these apply, a new tank unit may be the better recommendation, and you will be told so. When none apply, tankless is worth considering, and the $200 off tankless installation offer applies in Tennessee. Terms apply. No model specifications or savings figures are promised either way.
What goes wrong when a heater problem waits?
A tankless unit that is scaling up keeps narrowing until it fails or shuts down for good. A tank leaking from its body finishes the job on the floor. A failed element on a two-element tank makes every shower a race. A slow leak at the heater can be part of a mystery bill, which is where leak detection in Oak Ridge comes in. Hard water that is scaling the heater is a reason to discuss water softener and filtration in Oak Ridge at the same time. The cost of waiting is losing the chance to choose on your own schedule.

Great service! very knowledgeable. They work hard. They will go above and beyond.
We love how Dakota, was so friendly and kind, and very helpful, patient with my family we would call this service back anytime! Thank you Straight Shooter for coming out fast.
Dakota was very pleasant and very informative
Great service actually 24/7 service. Reasonable price for coming so late. Really clear on what the issue was and fixed it. But was honest that it not gonna last (roots in pipe) . Definitely would recommend them.
Dakota was very professional and worked quickly but fixed three toilets that had been “fixed” by three other plumbers who just made things worse. Very pleased with the work.
