Water Heater Leak Repair TeamWhen showers swing from scalding to lukewarm, or the reset button keeps tripping, the thermostat is the usual suspect — not the whole heater. Electric tanks use upper and lower thermostats working in sequence, and when one sticks or drifts, you get overheating that can even weep the T&P valve, or chronic lukewarm water that owners mistake for a dying tank. We test both thermostats under load, replace the failed one with an OEM-spec part, and set temperatures correctly for safety and efficiency.

Signs you need thermostat replacement
- Water far hotter or cooler than the dial setting

- Only the top third of the tank seems hot
- T&P valve dripping from overheating
- Inconsistent temperatures day to day
How our thermostat replacement visit works
Power verified off and tested
We confirm zero voltage at the elements before opening any access panel — no exceptions.
Thermostat diagnostics
We test continuity and calibration of upper and lower thermostats against actual tank temperature.
OEM-spec replacement
New thermostat seated flush against the tank wall for accurate sensing, wired to factory spec.
Temperature set and verified
We set a safe 120°F baseline and confirm stable operation through a full heating cycle.
Pricing
| Service | Price Range |
|---|---|
| Thermostat replacement (upper or lower) | $200–$350 |
| Both thermostats + element test | $300–$500 |

Built for Goose Creek conditions
Overheating from a stuck thermostat accelerates every corrosion process in the tank — in our humid market we treat thermostat faults as corrosion emergencies, not just comfort issues.
Every thermostat replacement job in the Goose Creek area includes our standard corrosion survey — we check the fittings, valves, and connections our humid climate attacks first, and we tell you what we find before you ask.
Frequently asked questions
Can a bad thermostat cause my T&P valve to leak?
Yes — a stuck thermostat lets the tank overheat, pressure climbs, and the relief valve opens to protect you. If both symptoms appeared together, the thermostat is the prime suspect and we check it first.
Should both thermostats be replaced together?
Not always. We test each independently and replace only what has failed — though on heaters past eight years, doing both in one visit can make economic sense. We will show you the test results and let you decide.
What temperature should my water heater be set to?
120°F is the safe, efficient standard — hot enough for household needs, cool enough to prevent scalding and slow mineral scaling that plagues Lowcountry tanks.
My reset button keeps tripping — is that dangerous?
The high-limit switch trips when the tank overheats, which means something is wrong upstream. Resetting it repeatedly without fixing the cause risks element burnout or worse — call (833) 713-2101 rather than making it a habit.
