Leaking or no hot water right now? Start here
If water is spreading from the tank, act before you call. Close the cold supply valve on the pipe entering the top of the heater by turning the handle a quarter turn or clockwise until it stops. That cuts the flow feeding the leak. Then keep people and pets out of the wet area.
Stop the supply
Shut the cold water valve above the tank. If the handle is seized or the leak is heavy, shut the main water valve for the house instead.
Kill the fuel or power
For an electric heater, switch off its breaker. Never step into standing water to reach a panel. For gas, turn the gas control to off only if the area is dry and you smell nothing.
Gas smell means leave
If you smell gas, do not touch switches or phones inside. Get everyone out, then call Eversource or 911 from outside. Call us after the gas utility clears the house.
Protect what you can
Move boxes off the floor, lay towels or a wet vac at the edge of the spill, and call (603) 815-9179 so a plumber can plan the right replacement unit for your fuel and space.
Water and electricity do not mix
A flooded basement floor with an electric water heater and a panel nearby is a shock risk. If water reaches outlets, appliances, or the panel, stay out and say so when you call.
Water heater leak: where it comes from and what it means
Most leaks fall into two groups. A leak from a fitting, valve, or supply line can often be repaired. A leak from the tank body itself cannot, because the steel liner has corroded through and the heater has to come out.
Water at the base
A puddle spreading from under the jacket usually points to the tank. Insulation inside gets soaked, and the metal has rusted through.
Drip from the relief valve
The temperature and pressure relief valve and its discharge pipe can drip when pressure runs high. This can be a failing valve or a missing expansion tank, so it needs a look.
Wet fittings on top
Moisture on the inlet and outlet connections or the flexible connectors is often a repair. We check whether the tank behind them is sound before deciding.
Water in the drain pan
A pan with standing water tells you something is leaking now or has been. A warm spot on the floor near the unit is a reason to call even if the pan is dry.
One related case is a hot water line that runs under the slab and leaks near the heater. It looks like a tank leak but is not. If the meter keeps moving with everything off, ask us about leak detection when we are on site.

Call the 24/7 line and we will dispatch a licensed plumber and book the earliest same-day visit when available.
No hot water in the house: replace, or just restart?
No hot water does not always mean a dead heater. A tripped breaker, a pilot that blew out, a failed thermostat, or a burned-out element can all do it. We test before we sell you a new tank, because a repair is the better answer when the tank is young and sound.
Replacement becomes the honest recommendation when the tank is leaking, when it is well past its usual service life, or when the repair would cost a large part of a new unit. Our water heater repair crews handle the cases that can be saved.
Repair or replace: a decision table
| What you see | Likely cause | Usual answer |
|---|---|---|
| Water leaking from the tank body | Corroded steel liner | Replace the heater |
| Drip at a fitting or valve, tank dry | Worn connector or valve | Repair, if the tank is sound |
| No hot water, tank young | Element, thermostat, igniter or pilot | Repair |
| Rust-colored hot water, tank old | Inside of tank breaking down | Replace soon |
| Rumbling or popping, low output | Sediment buildup | Flush, or replace if old |
| Repeated repairs in a short span | Tank is wearing out | Replace |
Age matters but is not the whole story. Look for the manufacture date in the serial number on the rating label, and ask the maker how to read it. A tank near the end of its life that develops a second fault is usually not worth fixing.
Anode rod, age, and the signs a tank is finishing
Inside every steel tank is an anode rod, a sacrificial metal rod that corrodes first so the tank does not. When the rod is used up, the steel starts to rust. Checking and swapping the rod can add life to a tank that is still dry, but once a tank has leaked, the rod no longer matters.
Signs the tank is near the end
- Rust-tinged hot water that clears when you run the cold tap
- Rumbling, popping, or knocking as the burner or element runs
- Moisture or rust streaks around the base or on the jacket
- Hot water that runs out faster than it used to
- A tank older than the maker's expected service life
- A relief valve that drips again after being replaced
Tank, tankless, heat pump, gas, or electric
Standard tank
Lowest upfront price and the easiest swap when the fuel and venting stay the same. It stores and reheats water, so it keeps losing a little heat all day.
Tankless
Heats water on demand and frees floor space. It needs the right gas line size, proper venting, and care in a cold space. See our tankless water heater page.
Heat pump (hybrid)
Moves heat from surrounding air into the water, using much less electricity than a standard electric tank. It needs open air space, a condensate drain, and the right electrical supply.
Gas versus electric
Gas heaters recover quickly and need a flue. Electric units need no flue but need the right circuit. Switching fuel changes the scope of work, so plan it before the old one fails if you can.
A heat pump water heater can be a sound replacement when the tank is in a basement or utility room with enough open air around it. In a tight closet or cold space in a Massachusetts winter, it works harder. Electric utilities and state energy offices often run incentives for heat pump water heaters, and terms change, so ask before you buy.
If the old tank fails at night, the plumber can talk through your options, including a switch to a different type, once the immediate problem is handled. For planned changes see water heater installation. Questions on the spot? Call (603) 815-9179.
What a replacement costs and why it varies
What affects the price of a water heater replacement
We do not quote a number over the internet because the answer depends on your house. You get a clear price before work starts, after the plumber sees the unit.
Want your real number? Call (603) 815-9179 and we will price your replacement before any work starts.
Permits, licensed plumbers, and the old tank
Under Massachusetts rules, plumbing permits are issued to licensed plumbers, and only a licensed plumber should replace your heater. Minor repairs are exempt, but a replacement is not. The Methuen Inspections Division issues plumbing permits, and the 2022 schedule listed a 50 dollar fee for a water heater. Check the current fees, because schedules change.
If the failure is a true emergency, state rules allow temporary emergency work, with the inspector notified and an inspection by the next working day. Our licensed plumbers handle that step. Homeowners can verify any plumber's license on the Mass.gov site before they hire.
Ask the plumber about removing the old tank, so you are not left with a rusted 100-pound shell in your cellar. Landlords and property managers can call the same line for a tenant with no hot water, and we coordinate access.
Questions we hear
Yes. Our emergency line runs 24/7, so a leaking tank at midnight or on a Sunday gets a dispatcher and a plan. We offer same-day appointments when available, and the dispatcher tells you what to shut off while you wait. Call (603) 815-9179.
A leak from the tank body means replacement. A fitting or valve leak, a bad element, or a failed thermostat is often fixable. Age, rust in the water, and repeated repairs push the answer toward replacing.
Shut the cold water valve above it, switch off the breaker for an electric heater, and keep people out of the wet area. If you smell gas, leave and call Eversource or 911.
A like-for-like swap is usually a half day job once the unit is on site. Fuel changes, new venting, or electrical work add time. The plumber confirms the plan before starting.
Often yes, if the electrical supply, space, and drainage allow it. A heat pump needs open air and a condensate drain. We check these on the visit and explain the options.
Yes. Permits are issued to licensed plumbers through the Methuen Inspections Division. The 2022 fee schedule listed a 50 dollar water heater permit, so check the current fees.
A little ticking as it heats is normal. Loud popping or rumbling points to sediment. Call us if noise continues after the first few days.
