Losing hot water is disruptive in a way few plumbing problems match. Whether your tank is leaking from a failed anode rod, your pilot won't stay lit, your electric element has burned out, or your tankless unit is flashing an error code โ Masters Plumbing Service's water heater techs in Watertown, CT arrive with diagnostic tools and replacement parts to resolve it in one visit.

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 CT.
Component-level testing takes 10โ15 minutes and produces a clear diagnosis โ not a guess that leads to replacing the wrong part.
For tankless units, we stock igniter assemblies, flow sensors, and descaling supplies for the major brands common in Watertown homes.
We give you the numbers. If repair costs approach 50โ60% of a replacement unit's installed price and the tank is over 8 years old, we tell you โ along with the reasons a new unit makes more financial sense. If the unit is young and the repair is minor, we say that too.
Every water heater installation in CT must meet current plumbing and mechanical codes โ 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 techs are trained on all major residential water heater types and brands. Here's how we approach each category.
Most common gas water heater repairs: failed thermocouple (pilot lights but won't stay on), faulty gas control valve, clogged burner orifice, failed thermopile, and depleted anode rod causing sulfur smell in hot water. We test the gas supply pressure at the unit, check thermocouple millivolt output with a meter, inspect the burner assembly, and confirm proper draft on the flue before recommending any repair.

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.
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 โ restoring flow rate and heating efficiency without replacing the unit.
T&P replacement is straightforward, but the discharge pipe must be correctly routed per code. We verify both the valve and the discharge piping on every replacement.
The sacrificial anode rod โ typically magnesium or aluminum โ corrodes preferentially inside the tank, protecting the steel tank lining. When depleted, the tank wall begins corroding instead. Most anode rods last 4โ6 years; hard water or softener use accelerates depletion. Replacing the anode on a mid-life tank is the single best investment for extending water heater life.

We carry 30-, 40-, and 50-gallon gas and electric units on the truck for same-day installation in Watertown. Tank-to-tankless conversions are also available where the existing infrastructure โ gas line capacity and electrical circuit โ supports the upgrade.
Here's what a Masters Plumbing Service water heater service call looks like in Watertown, CT.
No hot water? Rusty water? Pilot won't stay lit? Rumbling from the tank? Each symptom points to a short list of likely causes. Describing what you're seeing helps us arrive with the most probable replacement parts already on the truck.
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 15โ20 minutes rather than a vague 'it needs replacing' recommendation.
No pressure tactics. If repair makes sense, we say repair. If the math favors replacement, we show you why.
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.
Our 11-year-old gas water heater got a fair honest assessment: the tech showed us the repair cost vs. a new unit with installation and let us decide. We replaced it. Correct expansion tank installed, permit pulled, inspection passed. Everything by the book.
{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 ignition failure โ error code on the display. Tech checked the flame rod, found a cracked ceramic insulator causing intermittent short. Replaced the igniter assembly, unit fired clean on the first restart. Also checked venting for obstructions since venting issues cause similar ignition faults.
