While you wait: five things to do before we arrive
Safe steps for a heater that is leaking or cold
These are the only steps we ask homeowners to take. Everything else waits for the plumber.
- Close the cold supply valve on the pipe above the heater to stop water feeding a leak
- For an electric heater, switch off its breaker at the panel, but only from dry ground
- If you smell gas, leave the house and call Eversource or 911 from outside
- Put a bucket or wet vac at the edge of any spill and move stored items off the floor
- Keep children and pets away from hot pipes and wet floors
Do not keep resetting a breaker that trips over and over, and do not relight a gas pilot unless the label instructions walk you through it and there is no gas smell. If it will not stay lit, call. Repeated tries hide the real fault and can make it worse. If the heater still will not behave, write down what you saw and call the 24/7 line.
Leaking tank or leaking fitting? The difference decides everything
A leaking fitting, flexible connector, drain valve, or relief valve is a repair. A leak out of the tank shell is not. Water that appears at the bottom with the insulation soaked, or seeps from seams in the jacket, means the liner has corroded through.
Usually repairable
- Drip at the hot or cold connection on top
- Wet drain valve at the lower side
- Relief valve dripping with the tank dry
- Loose or corroded supply connector
Usually means replacement
- Water coming from under the tank body
- Rust streaks down the jacket
- Puddle that returns after the fitting is dry
- Tank old and leaking in more than one spot
If the verdict is the tank, our crews move straight to water heater replacement so you are not paying for two visits. Call (603) 815-9179 if you are not sure which side your leak falls on.
No hot water, or not hot enough
Lukewarm water, short hot showers, or nothing but cold are the usual calls we get on tanks. The cause depends on the fuel, so the first question is whether the heater is gas or electric. Both fail in predictable ways.
Gas: pilot or igniter
A pilot that will not stay lit, or an igniter that clicks without lighting the burner, points to a worn thermocouple, igniter, or gas control valve. Gas controls are licensed work.
Electric: element or thermostat
An electric tank has an upper and lower element, each with a thermostat. When one fails, you get a short supply of hot water or none at all. Power must be off before anyone opens a panel.
Tripped limit switch
A high-limit switch cuts power or gas if the water overheats. If it keeps tripping, there is a reason, and resetting it again and again is not the fix.
Sediment and scale
A layer of sediment at the bottom insulates the heating surface and wastes energy. Popping or rumbling sounds are the clue. A flush can help if the tank is sound.
Cold shower this morning?
Call the 24/7 line. A licensed plumber can usually diagnose on the first visit and book the earliest same-day slot when available.
How we find the fault
Read the label and history
We check the rating label for fuel type, capacity, and the manufacture date in the serial number, and ask when the problem began.
Test power or gas supply
With a meter for electric units and the controls for gas, the plumber checks whether the heating source is actually reaching the tank.
Test the parts
Elements, thermostats, igniters, thermocouples, and the relief valve are checked one at a time rather than replaced by guesswork.
Check the tank
The plumber looks for rust at the base, soaked insulation, and wet fittings to confirm the tank can be saved.

Repair or replace: how we weigh it
| Situation | Lean toward | Why |
|---|---|---|
| Tank under a few years old, one failed part | Repair | The tank is sound and the part is the cheap piece |
| Tank older than its expected life, new fault | Replace | Another failure is likely soon |
| Rusted or wet at the tank body | Replace | The liner cannot be fixed |
| Failed relief valve or connector only | Repair | Small parts, quick fix |
| Third repair in a short span | Replace | Repair costs keep adding up |
Ask the maker how to read the date code on your unit. A tank still within its expected service life with one bad part is almost always worth repairing. See installation options if you decide to switch fuel or size.
Any thermostat, element or valve we fit goes in according to the manufacturer's installation instructions for your model, and in Massachusetts gas water heater work is licensed work.
What drives the price of a repair
What affects the price
Repair prices swing with the part and the access. You get a clear price before work starts.

Hard water, sediment, and flushing
Minerals settle in the bottom of a tank and shorten its life. We do not publish a hardness number for Methuen because we have not verified one. Ask the Methuen Water Department for its annual water quality report, or test your tap with a simple kit, and tell the plumber the result.
Methuen draws its water from the Merrimack River and treats it with a corrosion inhibitor, as the water department's 2023 report describes. Whatever the hardness, a yearly look at the anode rod and a flush are cheap insurance. For tankless owners, the schedule is different and is covered on our tankless page.
Landlords and property managers
A tenant without hot water is an urgent matter, and heat or hot water complaints rarely wait. Call the 24/7 line, tell us who will give access, and we coordinate the visit and a clear price for you before work starts. We also serve rentals in Lawrence and other nearby towns.
Questions we hear
Yes. Our emergency dispatch runs 24/7, including nights, weekends, and holidays. We book same-day appointments when available. Call (603) 815-9179 and we will tell you which valve or breaker to handle while you wait.
A worn thermocouple, a dirty pilot assembly, or a draft problem are the usual suspects. Gas parts are licensed work, so do not open the gas control yourself.
A failed lower element or bad thermostat is the common cause. The tank may still heat the top section, so you get a short burst of hot water and then cool.
Codes vary by brand and model. The code on a gas or tankless unit points to ignition, venting, flame, or sensor faults. Photograph the code and the label and tell the dispatcher.
A tank flush is a drain and refill of sediment, but it involves hot water and a drain valve that can stick. If the valve has not been opened in years, let a plumber do it.
No. A constant drip means the valve has failed or pressure is running high. It is a safety device, so do not cap it.
If the leak came from a fitting and the tank is dry and sound, yes. If water is coming from the tank body, replacement is the honest answer.
