Water Heater Repair in Franklin & Nashville, TN
No hot water, a leaking tank, or rusty water? Prodigy repairs gas, electric, and tankless water heaters 24/7. We find out why before we quote, repair what can be fixed, and tell you honestly when a replacement makes more sense.
What Is Water Heater Repair?
Water heater repair is fixing the specific part that stopped a water heater from making hot water safely, instead of replacing the whole unit. On an electric tank heater that is usually a heating element or thermostat. On a gas tank heater it is usually the thermocouple, gas valve, or igniter. On any heater it can be a leaking fitting or a dripping temperature-and-pressure (T&P) relief valve.
Tankless water heaters fail differently: scale builds up in the heat exchanger, a flow sensor or igniter fails, and the unit shows an error code or shuts off mid-shower. Prodigy Sewer & Drain repairs all three types across Franklin, Nashville, and Middle Tennessee, and our water heater work carries a 2-year warranty.
What’s Wrong With My Water Heater?
Most water heater problems show up as one of seven symptoms, and each points to a short list of causes. Use this table to describe what you are seeing when you call; the technician confirms the cause by testing before quoting any repair.
| Symptom | Likely cause | What we do |
|---|---|---|
| No hot water at all | Electric: a failed element or tripped high-limit switch. Gas: a failed thermocouple, igniter, or gas valve | Test the part, replace what failed, and confirm safe operation |
| Hot water runs out fast | A failed lower element, sediment filling the tank, or a heater too small for the household | Test both elements, flush sediment, or size a replacement |
| Rumbling or popping | Sediment on the tank bottom boiling as the burner or element heats it | Flush the tank; heavy buildup can signal an aging tank |
| Rusty or brown hot water | A spent anode rod or a corroding tank lining | Inspect the anode; a corroding tank usually means replacement |
| Rotten-egg smell | Bacteria in the tank reacting with the anode rod | Flush the tank and replace the anode rod |
| Water at the base | A dripping relief valve, a loose fitting, or a leaking tank | Valves and fittings are repairable; a leaking tank body is not |
| Tankless error code or shut-off | Scale in the heat exchanger, a flow sensor, or the igniter | Descale flush and repair the failed component |
Is a leaking water heater an emergency? Yes, if water is pooling or spraying. Do this before you call:
- Close the cold-water supply valve on the pipe above the heater.
- Electric heater: switch off its breaker. Gas heater: turn the gas control knob to off.
- Move anything valuable away from the water, then call (615) 914-7349. We answer 24/7; a true after-hours emergency adds a $250 dispatch fee on top of standard rates.
How Does Prodigy Repair a Water Heater?
Every Prodigy water heater repair follows the same five steps, so you know the cause and the price before anything is replaced.
Phone Triage
If the tank is leaking, we talk you through shutting off the water and the power or gas while a technician is on the way.
Diagnosis
The technician tests the heater’s elements, thermostat, gas controls, and valves to find the part that actually failed.
Repair or Replace?
If a repair is sound, we quote it. If the tank itself is failing, we show you why and price a replacement instead.
The Fix
We install the right part, then run the heater and check for steady hot water and a safe relief valve.
Documented Work
You get a written record of what we found, what we replaced, and the 2-year warranty on the work.
Should You Repair or Replace Your Water Heater?
Repair a water heater when one part has failed and the tank is sound; replace it when the tank itself is leaking or corroding. A tank cannot be patched, so a leak from the tank body ends the repair question. Everything else depends on the age of the unit, how often it has failed, and whether it still keeps up with your household.
Repair usually makes sense when
- A single part has failed: an element, thermostat, thermocouple, igniter, or valve
- The tank is dry, with no rust at the seams or base
- The heater kept up with your household until it failed
Replacement usually makes sense when
- Water is leaking from the tank body
- The hot water is rusty because the tank is corroding
- The heater keeps failing, or a repair would cost a large share of a new unit
- Your household has outgrown it (see water heater installation)

Frequently Asked Questions
Should I repair or replace my water heater?
Repair it when a single part has failed, such as a heating element, thermostat, thermocouple, gas valve, or relief valve, and the tank itself is dry and sound. Replace it when the tank body is leaking or badly corroded, because a tank cannot be patched. Prodigy diagnoses first and gives you an honest recommendation either way.
Is a leaking water heater an emergency?
Yes, if water is pooling or spraying. Shut off the cold-water supply valve on the heater, switch off its breaker or turn the gas control to off, and call us. Prodigy answers 24/7 with full-time technicians, not on-call subcontractors.
How much does water heater repair cost in Nashville?
Prodigy’s standard dispatch is $29, and a true after-hours emergency adds a $250 emergency dispatch fee on top of standard rates. The repair price depends on the failed part and the heater type, and we confirm it after diagnosis, before any work starts.
Do you repair tankless water heaters?
Yes. Prodigy services gas, electric, and tankless water heaters, including diagnosing error codes and shutdowns and flushing scale out of tankless heat exchangers.
Why does my hot water smell like rotten eggs?
A rotten-egg smell in hot water usually comes from bacteria in the tank reacting with the anode rod. Flushing the tank and replacing the anode rod usually clears it. If the smell is in the cold water too, the cause is in the water supply rather than the heater.
Is your water heater work warrantied?
Yes. Prodigy’s water heater work carries a 2-year warranty.
