Why Choose Masters Plumbing Service

Why Dunbar Homeowners Trust Masters Plumbing Service for Water Heater Work

Water heater work involves gas lines, electrical systems, and pressure vessels — it isn't a DIY project or a job for a generalist. Our techs carry certifications specific to gas appliance work in SC.

🔬

Accurate Diagnosis First

We test before we quote. Gas units get thermocouple millivolt output checked, pilot assembly inspected, gas valve operation confirmed. Electric units get both elements and thermostats tested with a multimeter. A wrong diagnosis wastes money on a repair that doesn't fix the problem.

🔩

Stocked for Same-Visit Repairs

For tankless units, we stock igniter assemblies, flow sensors, and descaling supplies for the major brands common in Dunbar homes.

⚖️

Honest Repair vs. Replace

We don't recommend replacement to sell a unit. We work through the math with you openly so the decision is yours.

📜

Code-Compliant Installation

Every water heater installation in SC must meet current plumbing and mechanical codes — expansion tank where required by closed-loop systems, T&P discharge piped within 6 inches of the floor, correct flue sizing for gas units. We pull permits where required and schedule inspections.

Our Services

Water Heater Problems We Fix in Dunbar

Our techs are trained on all major residential water heater types and brands. Here's how we approach each category.

Gas Tank

Pilot, Thermocouple & Gas Valve Service

Thermocouple millivolt output drops below the 25mV minimum the gas valve needs to stay open well before the pilot stops working entirely. Regular output testing catches this before a cold shower.

Electric Tank

Element & Thermostat Service

A failed upper element causes loss of hot water entirely. A failed lower element produces hot water but in smaller volume. Knowing which symptom you're experiencing before we arrive helps us confirm the likely failure quickly on-site.

Tankless

Tankless Water Heater Repair & Descaling

Scale buildup in the heat exchanger is the leading performance issue in tankless units in hard-water areas. We perform a citric acid descaling flush through the heat exchanger using flush kit ports — restoring flow rate and heating efficiency without replacing the unit.

Safety

Temperature & Pressure Relief Valve Service

A T&P valve that drips constantly, won't reset after testing, or shows visible corrosion needs immediate replacement — it's failing in the closed position, removing the safety protection it provides. We replace the valve with a listed unit rated for the tank's BTU input and install or verify the discharge piping before leaving.

Longevity

Tank Life Extension in Dunbar

Anode rods in Dunbar areas with hard water or water softener systems deplete faster than the national average. We check anode condition whenever we have the tank open for any other service — it adds 5 minutes and can add years to the unit's service life.

Replacement

Same-Day Tank & Tankless Installation

When a tank is beyond economic repair — internal corrosion, cracked tank shell, or a unit over 10–12 years old with multiple failing components — replacement is the right answer. We carry 30-, 40-, and 50-gallon gas and electric units on our trucks for same-day installation. We also perform tank-to-tankless conversions where the existing infrastructure supports it.

How It Works

Our Diagnostic & Repair Workflow

We don't guess at water heater problems. Each call follows a structured diagnostic process that identifies the specific failed component before any repair recommendation is made.

Describe the Symptoms When You Call

Knowing the fuel type, tank size, and approximate age also helps pre-load relevant parts before leaving the shop.

Component-Level Diagnosis On-Site

We test the specific components implicated by your symptoms — thermocouple output for gas units, element continuity for electric units, error code analysis for tankless. This focused approach produces a clear diagnosis in 15–20 minutes rather than a vague 'it needs replacing' recommendation.

Repair vs. Replace Quote

You receive a flat-rate quote for the repair and, where relevant, a replacement option with installed price for comparison. We walk through the numbers — repair cost vs. unit age vs. replacement cost — and let you decide with full information.

Same-Visit Repair or Replacement

Approved repairs happen immediately. For replacements, we drain and disconnect the old tank, install the new unit with proper flex connectors and expansion tank where required, verify the flue or venting, and test the unit through a full heat cycle before leaving.

Customer Reviews

Real Water Heater Repair Reviews from Dunbar

★★★★★

Gas water heater stopped heating on a Thursday evening. Masters Plumbing Service had a tech out Friday morning who tested the thermocouple — millivolt output was at 12mV, well below the 25mV minimum. Replaced the thermocouple and pilot assembly in 45 minutes. Total cost was under $200 and the tech told me the price before touching anything. No upsell attempt at all.

{Electric water heater wouldn't recover — 10 minutes of hot water then cold. Masters Plumbing Service's tech identified the lower heating element had failed, drained the tank, replaced the element and lower thermostat while he was in there, and restored full recovery capacity. Explained the difference between upper and lower element function which I'd never understood.|T&P valve dripping continuously. Tech identified it wasn't just thermal expansion but a valve that had corroded open. Replaced the valve, re-routed the discharge pipe to code, verified tank pressure was in normal range. All in under 2 hours.}

★★★★★

Tankless Navien unit throwing error code 027 — heat exchanger overtemp. Tech explained that's almost always scale buildup restricting flow. Performed a citric acid descaling flush through the service ports, restored normal flow. Unit's been running clean ever since. Much cheaper than I expected and no replacement needed.

FAQ

What to Know Before Calling for Water Heater Repair in Dunbar

If the pilot won't light at all, the issue may be the pilot orifice or the gas control valve. Both are diagnosable and usually repairable. We work through the gas train systematically.

Visible rust staining near the base or around the T&P valve outlet often indicates internal corrosion. Once the tank lining is breached, no repair holds long-term. We check for these signs before recommending a repair that won't last.

Rusty or brown hot water usually means the sacrificial anode rod has been depleted and the tank lining has begun to corrode. Anode rod replacement may buy additional service life — particularly if the tank lining is otherwise intact. In some cases it signals that internal corrosion is already advanced and the tank is near end of life.

Common repairs — thermocouple, heating element, T&P valve — complete in 45 minutes to 1.5 hours. A gas valve replacement takes 1.5–2 hours including testing the unit through a complete heat cycle. Tankless descaling runs 1–2 hours. Full replacement of a tank water heater takes 2–3 hours including draining, disconnecting, installing, and testing.

In most jurisdictions in SC, yes — water heater replacement requires a plumbing permit and inspection, particularly for gas units. We pull the required permit as part of the installation and coordinate the inspection. The cost of permitting is disclosed in your quote.

Yes, for the most common residential tank sizes — 40 and 50-gallon gas and electric units. Our trucks carry these for same-day installation. If your unit is out and you need hot water today, call us first thing and we'll get a tech scheduled.
