This guide anchors our water heater services services in South Dakota — the specialized fixes below go deeper on each job, and the full water heater services catalog lists everything we handle.
Water heater repair covers a wide range of failures — from a $25 thermocouple that takes 30 minutes to a control valve or heat exchanger that takes longer. Our plumbers diagnose to the component level rather than recommending replacement as the default. A 5-year-old Rheem with a bad element or a Navien tankless throwing an ignition error is almost always worth repairing; the same tank at 13 years old with a rusted-through bottom is usually worth replacing.
Trucks stock the common parts for the major brands: upper and lower heating elements and thermostats for electric tanks, thermocouples, thermopiles, gas control valves, and pilot assemblies for gas tanks, and igniters, flame sensors, and flow sensors for Navien and Rinnai tankless units. The 96% first-call fix rate applies to water heaters too — most no-hot-water calls are diagnosed and resolved in the same South Dakota visit.
Every water heater repair includes a full operational check after the fix: temperature verified at the tap, the T&P relief valve tested, the burner or elements confirmed cycling correctly, and — on tank units — a sediment flush to protect the parts we just replaced. If you've been living with lukewarm water or a pilot that won't stay lit, the post-repair check is often a noticeable improvement on its own.
Boiler Repair — if the failing unit heats radiators or baseboards, not tap water.
What tells us a home needs water heater repair
No hot water at all
A dead pilot, tripped thermostat, or failed element leaves the tank cold. Fix is usually a thermocouple, reset, or element swap — often $89–$189 in parts and under an hour of labor on a South Dakota call.
A failed upper element or thermostat, or a burner running low, leaves the water lukewarm. Diagnosis is free in the South Dakota service call; the element or thermostat swap is a same-visit fix.
Tankless throwing an error code
Navien and Rinnai units flash a code for ignition, flow, or scale faults. We read the code, descale or replace the sensor, and clear it during the South Dakota visit.
Popping or rumbling tank
Sediment on the tank bottom rumbles and insulates the burner, wasting fuel. A flush during the South Dakota visit restores efficiency and quiets it.
Pilot won't stay lit
A failing thermocouple or dirty pilot assembly drops the flame seconds after you light it. We carry both on the truck and isolate the cause at your South Dakota home.
Common causes & what we fix
Sediment buildup
Hard-water minerals settle in the tank, insulate the burner or lower element, and force it to overheat — the most common cause of a failed element or a noisy tank we see in South Dakota. A flush prevents most of these calls.
Thermocouple or thermopile age
The flame-sensing components on a gas tank weaken over 5–8 years until the gas valve won't stay open. A routine South Dakota fix that restores a pilot that won't stay lit.
Element or thermostat failure
Electric tank elements burn out and thermostats drift out of calibration around 6–10 years. A $150–$250 element-and-thermostat swap extends the tank another several years, and it's one of the most common South Dakota repairs.
Scale in a tankless heat exchanger
Hard water scales the tankless heat exchanger, dropping output and throwing error codes. A descaling flush restores it; we carry the kit on every South Dakota truck.
Gas valve or control failure
Control valves fail from age and sediment. Rheem and Bradford White valves run $200–$350; often worth replacing on a 5–10 year old tank, rarely past 13 years. We stock them on every South Dakota truck.

What homeowners ask about water heater repair
Top questions homeowners searching for Water Heater Repair near me ask us:
Can you relight a pilot in South Dakota?
Yes — and we diagnose why it went out. A pilot that won't stay lit usually needs a thermocouple, which we carry on every South Dakota truck, so it's a same-visit fix rather than a repeat outage.
Is it worth repairing vs replacing in South Dakota?
Rule of thumb: under 8 years old, repair almost always. 8–12 years, depends on the failure. 12+ years and a corroded tank or major control — usually replace. We'll quote both for your South Dakota home so you can decide.
What's covered after a repair in South Dakota?
Repair labor and replacement parts are backed for 1 year. Manufacturer parts from Rheem, Bradford White, and Navien are covered under their own warranties. We service ZIPs and the surrounding South Dakota area.
How long does a water heater repair take in South Dakota?
Most repairs are 45–90 minutes including diagnosis. Element and thermostat swaps run under an hour; gas valve and tankless descaling take 90–120 minutes — same-visit across South Dakota.
Do you repair tankless units across South Dakota?
Yes — Navien, Rinnai, Rheem, and Bosch tankless, including descaling, sensor replacement, and error-code diagnosis. Some off-brand tankless have unavailable parts; we'll tell South Dakota homeowners upfront if that's the case.
