Services / Water heaters
No hot water? We can usually fix that today.
From a leaking heater in a Brooklyn apartment to a commercial unit down in a Manhattan restaurant, our technicians arrive prepared to diagnose, repair or replace. Same-day service for most calls.
1Cold supply & shut-off
Brings cold water into the heater. The shut-off valve on this line stops water to the tank.
Watch forA valve that won’t close all the way, or drips at the handle.
2Dip tube
Carries the incoming cold water to the bottom of the tank, so it doesn’t mix with the hot water at the top.
Watch forHot water that runs out much sooner than it used to.
3Hot outlet
The hottest water sits at the top of the tank. It leaves here and goes to your faucets.
Watch forLukewarm water at every faucet in the home.
4Relief valve
A safety valve. It opens to release water if the temperature or pressure in the tank gets too high.
Watch forWater dripping or discharging from its pipe. Never cap or plug it.
5Gas valve & thermostat
Sets the water temperature and controls the gas going to the burner.
Watch forA pilot that won’t stay lit, or no hot water at all.
6Burner & flue
The burner heats the tank from underneath. Exhaust rises through the flue in the middle of the tank and out the vent.
Watch forSoot around the heater, a yellow flame, or a rumbling or popping sound.
7Tank & anode rod
A lined steel tank holds the hot water. The anode rod inside corrodes first, which protects the tank.
Watch forRusty hot water, or water on the floor under the tank.
8Drain valve
Used to drain the tank and flush out the sediment that settles at the bottom.
Watch forA drip at the valve that doesn’t stop.
Signs it needs service
No hot water at all
Pilot out, a failed gas valve or thermocouple, or a tripped reset.
Leaking at the base or connections
Shut off the cold supply and call. It can worsen quickly.
Runs out faster than usual
Worth a check before it stops altogether.
Rusty, brown or sulfur-smelling water
Have it looked at. Internal tank corrosion usually means replacement.
Popping, banging or rumbling
Noises from the tank are a reason to call.
More than 10–12 years old
Repeated pilot outages or a relief valve releasing water are also signs it’s time.
Questions
Water heaters: common questions
Why do I have no hot water?
On gas heaters, the pilot may be out, or the gas valve or thermocouple may have failed. On any type, it could be a faulty heating element, a broken thermostat or a tripped reset button.
Should I repair or replace my water heater?
Under 10 years old with a minor problem: repair it. Over 12 years old, recurring issues, or a repair above half the cost of replacement: a new unit is usually the better investment.
My water heater is leaking. What should I do?
Turn off the cold water supply valve on top of the heater. On gas units, turn the gas valve to PILOT. Then call us. A leak can worsen quickly and may mean internal tank corrosion, which usually means replacement.
How long does water heater replacement take?
Most residential tank replacements take 2–4 hours, including removing the old unit. We handle all required permits and inspections.
What water heater brands do you work with?
All major brands, including Rheem, Bradford White, A.O. Smith, State, Navien, Rinnai and Noritz. We can help you choose the right unit for your home or building and budget.
Do you offer water heater service at night or on weekends?
Yes. Emergency service runs 24/7 every day of the week, including nights, weekends and holidays.
