TPR Valve Replacement
The T&P valve is the tank’s pressure whistle — it opens near 210°F or 150 psi. When it weeps, we determine whether the valve has worn out or the system pressure is genuinely high, then install a correctly rated replacement.

Water Heater Replacement in Medford, MA
There is a line in water heater anatomy that no repair crosses: the tank shell itself. Valves, fittings, gaskets, thermostats — all replaceable. But a steel vessel that has corroded through from the inside or cracked under years of stress cannot be patched back into a pressure vessel. When we find that failure, we say so plainly and recommend replacement. Our water heater replacement in Medford, MA installs a correctly sized unit for your household, evaluates the expansion tank, and tests the full installation. Call (833) 713-2101.

About this service
When the tank shell itself is done
The shell fails the way steel fails: from the inside out. The glass lining develops micro-fissures, the anode rod — the sacrificial decoy — gets consumed (roughly every 3 to 5 years), and then corrosion turns on the steel itself. Sediment accelerates the whole drama, insulating the tank bottom and overheating the metal. The result is pinholes that weep, seams that split, or a base that rusts through — and none of it is repairable, because a pressure vessel with compromised walls is not a candidate for patches.
Replacement is a full reset: the old unit drained, disconnected, and removed; the new one set, connected with fresh supply lines and dielectric unions, vented correctly on gas models, with the expansion tank evaluated and the system pressure-checked. Sizing matters — a household’s hot-water demand should match the tank — and so does the thermostat setting, around 120°F for most homes. We will always tell you honestly when replacement beats another repair. For water heater replacement in Medford, MA, call (833) 713-2101.
How it works
Expect this
Confirm the shell has failed
We verify the leak is truly from the tank body — not a fitting or valve in disguise — before recommending replacement.
Size the new unit
Household demand, fuel type, and space determine the right capacity — a replacement should fit the home, not just the closet.
Remove the old heater
Drained, disconnected, and hauled out — gas or power isolated first, always.
Install and connect
New unit set and leveled, fresh supply connections with dielectric unions, proper venting on gas models, expansion tank evaluated and matched.
Test the full system
Filled, purged, fired, pressure-checked — T&P verified, thermostat set, hot water confirmed at the taps.
FAQ
Your Replacement Questions, Answered
How do I know the tank itself has failed?
Location and evidence: water seeping from the tank body or seams — not from any valve or fitting — often with rust streaks or a damp shell that never dries. We dry the tank and trace upward first, because fittings love to impersonate tank failures.
How long do water heaters usually last?
Typically 8 to 20 years depending on type, with maintenance — flushing, anode checks — pushing toward the long end. A leaking shell near the end of that range is the tank telling you it is finished; a young tank with a shell leak deserves a hard look at water quality and installation.
What happens to the old unit?
We drain it, disconnect it, and remove it from your home as part of the replacement — you are left with the new installation, tested and running, not a dead tank in the garage.

Water Heater Drain Valve Repair
The drain valve is the spigot at the tank’s ankle — a classic drip point when its washer hardens or the plastic body cracks. We replace failed valves with solid brass that seals and makes future flushing easier.
Leaking Fitting and Connection Repair
Where the tank meets the house plumbing — inlet, outlet, dielectric unions — heat cycling works fittings loose over time. We reseat or replace them, then pressure-test each connection.
Tankless Water Heater Leak Repair
No tank, different anatomy: tankless units leak from heat-exchanger seals, condensate lines, and isolation valves. We diagnose the tankless-specific failure points and restore sealed operation.
Leak Pan and Drain Line Installation
A pan under the tank with a drain line carries slow leaks to a drain before they reach your floors. Simple, passive protection — especially valuable in closets, attics, and finished spaces.
Gas Water Heater Leak Repair
A gas heater is two systems in one cabinet: water and fuel. We shut the gas down first, repair the water-side leak, then verify burner, pilot assembly, and venting before relighting.
Electric Water Heater Leak Repair
Electric tanks add their own leak points: heating-element gaskets and thermostat covers. We kill power at the breaker, replace the failed seal, and prove both elements heat.
Expansion Tank Service
The expansion tank is the shock absorber of a closed plumbing system. When its bladder fails, pressure spikes and the T&P valve discharges — we test, replace, and match pre-charge to your home.
Water Heater Shutoff Valve Replacement
The cold-water shutoff is the first valve you reach for in a leak — and old gate valves often refuse to close. We replace them with quarter-turn ball valves that shut with one motion.
Emergency Water Heater Leak Repair
An active leak gets triage first: stop the water, make the unit safe, then diagnose the failed part and complete a lasting repair. If water is spreading, shut the supply off if you safely can, then call (833) 713-2101.
