Water Heater Repair, Installation and Replacement
No cold-shower roulette, no guesswork, no pressure to replace a unit that just needs a part. We diagnose honestly, repair when repair makes sense, and install tank and tankless systems sized to how your household actually uses hot water.
Book a Water Heater VisitSix warning signs your water heater is failing
Water heaters rarely die suddenly. They fade, and the symptoms below are how they tell you. Catching them early is the difference between a scheduled water heater repair visit and a flooded utility room. If you recognize sign five or six, act today rather than this weekend.
Water is not as hot, or runs out faster
A failing heating element, a stuck dip tube, or a tank half-full of sediment all shrink your effective hot water supply. If showers went from twenty comfortable minutes to eight lukewarm ones, the heater is working harder to deliver less.
Rumbling, popping, or crackling sounds
That percolator sound is water boiling underneath a layer of hardened sediment on the tank floor. The overheated steel beneath fatigues over time, which shortens tank life and wastes energy with every heating cycle.
Rusty or metallic-tasting hot water
If discoloration appears only on the hot side, the anode rod is likely spent and the tank interior has started corroding. Replacing the anode early can add years; ignoring it lets rust finish the job from the inside out.
The pilot light will not stay lit
A pilot that keeps dropping usually points to a failing thermocouple or gas control valve rather than user error. Both are repairable, and neither should be worked around by relighting it every morning.
Moisture, drips, or corrosion at fittings
Dampness around the connections or relief valve may be a fixable fitting leak, but check quickly: water travels, and what looks like a loose fitting can be the first visible evidence of a tank seam failing.
Water pooling under the tank
Water from the tank body itself means the internal liner has failed, and no repair reverses that. Shut off the cold supply and the fuel source, and call us. If it is actively flooding, treat it as an emergency plumbing call, any hour.
Repair or replace? Here is how we actually decide
The right answer comes from three numbers: the unit’s age, the cost of the repair, and the cost of a comparable new installation. We put all three in front of you and let the arithmetic talk. As a rule of thumb, when a repair exceeds half the cost of replacement on a tank past its eighth birthday, replacement wins on every timescale that matters.
Repair usually wins when…
- The unit is under 8 years old and the tank itself is sound
- The failure is a single component: thermostat, heating element, thermocouple, igniter, or relief valve
- Hot water quality is fine and the tank is quiet; the problem is control-side, not tank-side
- A tankless unit needs descaling or a sensor rather than a new heat exchanger
Component repairs are quick, economical, and often completed in a single visit from truck stock. We warranty the work, and we tell you the honest remaining-life outlook so a repair never becomes a surprise down payment on next year’s failure.
Replacement usually wins when…
- The tank is leaking from the body. This is terminal, full stop
- The unit is past 10 years and needs anything expensive
- Rust-colored hot water persists after flushing, meaning internal corrosion is advanced
- Repair bills are becoming a subscription: two or more in eighteen months
- Your household outgrew the tank, and demand-days end in cold showers
Replacement day is also decision day: same-size tank, larger tank, high-efficiency tank, or a switch to tankless. Our comparison guide on tankless vs tank water heaters walks through that choice in detail before we ever quote it.
Systems we install and service
We work on every common residential configuration, gas and electric, and we size installations from your actual fixture count and usage patterns rather than from whatever is on the truck.
The familiar 40 to 75 gallon storage tank remains the value benchmark: lower upfront cost, simple maintenance, and straightforward like-for-like replacement, often completed the same day.
- Gas and electric models, 40 to 75 gallons
- Code-current installation: expansion tank, pan, seismic strapping, and venting
- Old unit hauled away and recycled
Tankless units heat water only as you use it, delivering endless hot water, a 20 year service life, and meaningful energy savings for many households. They demand correct gas sizing, venting, and condensate handling, which is exactly the part we do not improvise.
- Load calculation and gas line verification before quoting
- Whole-home and point-of-use configurations
- Annual descaling service to protect the heat exchanger
Heat pump water heaters move heat rather than generate it, cutting water heating energy use by well over half in the right space. They need adequate air volume and condensate drainage, and they reward the investment with dramatically lower operating costs.
- Placement assessment for airflow, clearance, and noise
- Utility rebate paperwork guidance where available
- Ideal for garages and large utility rooms
The maintenance schedule that doubles a heater’s useful life
Every year of a water heater’s life, minerals settle, anodes sacrifice themselves, and valves age. A modest maintenance rhythm keeps efficiency high and converts sudden failures into planned upgrades. This is the schedule we recommend and perform.
- Every 6 months
Quick visual check
Look for moisture at fittings, corrosion streaks, and scorch marks. Sniff for gas near the burner compartment. Two minutes, zero tools, catches the majority of early failures.
- Yearly
Flush the tank
Draining a few gallons until the water runs clear removes the sediment layer that causes rumbling, wasted fuel, and floor-plate fatigue. Homes with hard water benefit from a full flush.
- Yearly
Test the T&P relief valve
The temperature and pressure relief valve is the tank’s last line of defense. Lifting the lever should produce a burst of water into the discharge tube. A valve that dribbles constantly or does not flow at all gets replaced.
- Every 2-3 years
Inspect the anode rod
The sacrificial anode corrodes so your tank does not. Once it is consumed to the core wire, the tank starts eating itself. A timely anode swap is the single best longevity purchase a tank owner can make.
- Yearly (tankless)
Descale the heat exchanger
A vinegar or descaler circulation flush clears mineral scale before it throttles flow and efficiency. In hard water areas this single service protects the most expensive component in the unit.
Two of these tasks, the tank flush and the relief valve test, are genuinely DIY-friendly for a comfortable homeowner, and we are happy to demonstrate both during any visit so you can carry them forward yourself. The anode inspection and tankless descaling sit better in professional hands, partly for the tooling and partly because both are natural moments for a trained eye to catch the early failure signs from the top of this page while the unit is already opened up. Homes on our annual maintenance visits replace their water heaters on schedule and on sale pricing; homes that skip maintenance replace them on the coldest morning of the year at emergency rates. The tank does not care which you choose, but your budget does.
Worth knowing: a slow leak at a water heater connection often announces itself first as a mystery on your utility bill or a warm spot on the floor. If you suspect water is escaping somewhere you cannot see, our leak detection services find it with instruments instead of demolition.
Gas or electric: the fuel question, answered honestly
Most replacements keep the existing fuel type because switching adds cost, but “most” is not “all,” and the tradeoffs are worth understanding before you sign anything.
Gas units heat water roughly twice as fast as standard electric elements and usually cost less to run where natural gas is cheap, which keeps them the default in homes that already have gas service at the heater location. Their costs of ownership hide in the details: combustion needs correct venting, burners and thermocouples add service items, and installation code has more moving parts. Electric units are simpler machines with fewer failure modes, install almost anywhere without venting, and pair naturally with the heat pump technology that now dominates the efficiency conversation. Their weakness is recovery speed on standard elements and operating cost where electricity is expensive.
The interesting modern case is the heat pump water heater, which runs on electricity but sidesteps the operating cost argument by moving heat instead of generating it, typically using two thirds less energy than a standard electric tank. For homes with a suitable garage, basement, or utility room, and especially where rebates apply, it has become the configuration we find ourselves recommending most often when a customer asks what we would put in our own house. What we will not do is push a fuel switch that requires expensive new infrastructure just to inflate a quote: if your current setup serves you well, a like-for-like replacement is usually the honest recommendation, and we will say so.
What installation day looks like
A water heater replacement done properly is a half-day appointment with a predictable rhythm. Here is the sequence, so nothing about it surprises you.
Your installer starts by protecting the path from the door to the heater with runners, then drains the old tank, disconnects fuel and water, and hauls the unit out for recycling. The new unit goes in with the details that separate a code-correct installation from a swap: new supply connectors and shut-off valve if the existing ones show age, a thermal expansion tank where the water system requires one, a drain pan piped to a safe termination when the location calls for it, seismic strapping where applicable, correct venting with proper rise and clearances on gas units, and a temperature and pressure relief discharge tube terminated the way inspectors expect to find it.
Then comes the part rushed installs skip: the system is filled and purged of air, fuel connections are leak-tested, the burner or elements are verified under load, the thermostat is set to 120 degrees, and the installer walks you through the shut-off locations, the relief valve, and the maintenance schedule from the section above. Where your jurisdiction requires a permit and inspection, we handle the paperwork and meet the inspector. You end the day with hot water, documentation for your records and warranty, and a heater whose installation will not be the reason it fails early. The whole visit typically runs three to five hours for a like-for-like tank, longer for tankless conversions and heat pump units with new electrical or condensate runs.
Water heater questions we answer every day
How long should a water heater last?
Conventional tanks average 8 to 12 years, with hard water and skipped maintenance pulling that number down and annual flushing plus anode replacement pushing it up. Tankless systems commonly reach 20 years or more with yearly descaling. If your tank is past a decade and you are reading this page because something seems off, start budgeting for replacement on your schedule instead of the tank’s.
What size water heater does my home need?
For tanks, the honest sizing input is your busiest hour: how many showers, laundry loads, and dishwasher cycles overlap. A household of four typically lands at 50 gallons or more, but usage patterns beat headcount. For tankless, sizing is about simultaneous flow and incoming water temperature. We calculate both rather than guessing, because an undersized unit disappoints daily and an oversized one wastes money upfront.
Why does my hot water smell like rotten eggs?
Sulfur odor on the hot side usually comes from bacteria reacting with the anode rod in the tank. It is not dangerous in a disinfected municipal system, but it is unpleasant. A tank flush and disinfection plus an anode swap, often to an aluminum-zinc or powered anode, typically resolves it for good.
Can I replace a water heater myself?
Legally, in most jurisdictions, a water heater replacement requires a permit, and for good reasons: the job combines gas or high-amperage electrical work, venting of combustion gases, temperature and pressure safety devices, and code items like expansion tanks and drain pans. Mistakes are not cosmetic; they are carbon monoxide, scalding, and flood risks. This is one of the jobs where professional installation genuinely pays for itself.
What temperature should I set my water heater to?
120 degrees Fahrenheit is the standard recommendation: hot enough for cleaning and comfort, low enough to slow scale formation and sharply reduce scald risk, especially for children and older adults. Households with immune-compromised members sometimes run 140 degrees with mixing valves at fixtures; if that applies to you, ask us about it during your visit.
Why does hot water take so long to reach my faucet?
Distance, not a defect. Every foot of pipe between the heater and the fixture holds cooled water that must be pushed out before hot arrives, and in a large single-story home that can be a minute of waiting and gallons down the drain per draw. The fix is a recirculation system: a small pump, either dedicated-loop or retrofit with a crossover valve at the far fixture, keeps hot water staged near the taps. Modern smart recirculation pumps run on schedules or motion sensors rather than around the clock, which preserves most of the energy savings. It pairs especially well with tankless systems, where it also eliminates the cold water sandwich.
Do I need an expansion tank?
If your home has a closed plumbing system, meaning a check valve or pressure-reducing valve separates you from the street, then yes, and many jurisdictions require one at replacement. Heated water expands, and in a closed system that expansion has nowhere to go, so pressure spikes hammer the relief valve, fixtures, and the tank itself with every heating cycle. An expansion tank gives the extra volume a cushion. It is an inexpensive component that quietly prevents a family of expensive symptoms, including relief valves that drip forever and premature tank failure.
Is a tankless upgrade worth it?
It depends on your gas capacity, your usage, and how long you plan to stay in the home. Tankless wins on lifespan, floor space, and endless hot water; tanks win on upfront cost and simplicity. We lay out the ten-year math for your actual household in our tankless vs tank comparison guide, and we install both, so the recommendation is not self-serving.
