Why Choose Masters Plumbing Service

Why Strafford Homeowners Trust Masters Plumbing Service for Water Heater Work

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

๐Ÿ”ฌ

Accurate Diagnosis First

Component-level testing takes 10โ€“15 minutes and produces a clear diagnosis โ€” not a guess that leads to replacing the wrong part.

๐Ÿ”ฉ

Stocked for Same-Visit Repairs

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

โš–๏ธ

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.

๐Ÿ“œ

Code-Compliant Installation

Code compliance isn't just legal protection โ€” a missing expansion tank or improperly discharged T&P valve creates real risk. We install to code every time.

Our Services

Tank, Tankless & Heat Pump โ€” We Service All Types

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

Gas Tank

Gas Water Heater Repair in Strafford, NH

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.

Professional Water Heater Repair technician working in Strafford, NH
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

Tankless units fail in specific, diagnosable ways: ignition failures (error codes for igniter or flame rod), flow sensor malfunctions (unit won't fire when water runs), heat exchanger scale buildup (overtemp or reduced flow error codes), and venting issues (pressure switch errors on direct-vent units). We read the error code, check the relevant component, and repair or replace what actually failed.

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 โ€” 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

Anode Rod Replacement

Anode rods in Strafford 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 โ€” it adds 5 minutes and can add years to the unit's service life.

1

Describe the Symptoms When You Call

2

Component-Level Diagnosis On-Site

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

Repair vs. Replace Quote

No pressure tactics. If repair makes sense, we say repair. If the math favors replacement, we show you why.

Customer Reviews

What Strafford, NH Homeowners Say About Our Water Heater Work

โ˜…โ˜…โ˜…โ˜…โ˜…

Gas water heater stopped heating on a Thursday evening. Masters Plumbing Service had a tech out Friday morning who tested the thermocouple โ€” 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 โ€” 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 โ€” 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

Water Heater Questions We Answer Every Day

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.
The main factors: unit age, repair cost relative to replacement cost, and whether the tank shell itself is compromised. A 4-year-old unit with a failed thermocouple is always a repair. A 13-year-old unit with a leaking tank bottom is always a replacement. The judgment call is units 8โ€“11 years old with a significant repair need โ€” we show you both numbers and let you decide.
We inspect the anode rod condition when we diagnose this complaint and give you an honest read on whether replacement makes sense.
Common repairs โ€” thermocouple, heating element, T&P valve โ€” complete in 45 minutes to 1.5 hours. A gas valve replacement takes 1.5โ€“2 hours including testing the unit through a complete heat cycle. Tankless descaling runs 1โ€“2 hours. Full replacement of a tank water heater takes 2โ€“3 hours including draining, disconnecting, installing, and testing.
In most jurisdictions in NH, yes โ€” 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.
For less common configurations โ€” 75-gallon commercial units, 10-inch rough-in tanks, specific tankless models โ€” we may need to source the unit first. We'll tell you the realistic timeline at dispatch.
