Leaking tank: what to do right now
When a water heater tank leaks, the damage grows with every hour. Dispatch answers 24/7, and we offer same-day replacement when a unit and a plumber are available. In the meantime, you can limit the water yourself.
- Close the cold water shutoff valve on the pipe above the heater. This stops new water entering the tank.
- Turn off the heat source. For electric, switch off the breaker only if you can reach the panel without standing in water. For gas, turn the control to off or close the gas valve.
- Open a hot tap upstairs so the tank does not hold a vacuum, then attach a hose to the drain valve and run it to a floor drain.
- Move belongings off the floor, mop up and call.
A gas odor at any stage changes everything. Walk out, put 350 feet between you and the building, and only then phone PSE&G on 1-800-880-PSEG (7734) or 911. Leave switches and doorbells alone on the way.
Signs the tank is finished
When a water heater needs replacing
One of these is a warning. Two or more usually mean the tank is at the end.
- Water pools around the base and the tank wall is wet or rusted.
- Rust-colored hot water, or a metallic taste, from the hot tap only.
- Rumbling or popping noises from sediment baked into the bottom.
- Repeated repairs within a short period.
- The unit is old enough that parts are hard to find. The serial number gives its age.
If the water is only cold, you may not need a new heater at all. Our water heater repair page covers thermostats, elements and igniters that fail on a healthy tank.
Replace or repair: a decision table
| Situation | Better move | Reason |
|---|---|---|
| Tank body leaks | Replace | Corroded steel cannot be patched |
| Failed element or thermostat on a young tank | Repair | Small part, healthy tank |
| Old tank with a failed gas valve | Often replace | The repair can approach the cost of a new unit |
| Repeated failures of different parts | Replace | Other parts are likely close behind |
| Anode rod worn but tank sound | Repair | A fresh rod can extend life |
Tank, tankless or hybrid heat pump
A replacement is a chance to change the type. A standard tank heats water and holds it, and is the simplest swap. A tankless unit heats water as you use it and takes less space, which is covered under tankless water heater. A hybrid heat pump heater draws heat from the air around it and uses less electricity, but needs open airflow and room for a condensate drain.
The right choice depends on fuel, space and how many people share the hot water. Fuel changes need new gas lines, venting or wiring, so tell the plumber early.
Anode rod: the repair that extends life
Inside a steel tank sits an anode rod made of softer metal. It corrodes first, so the steel does not. When the rod is gone, the tank starts rusting from inside.
If your tank is sound but the rod is worn, replacing the rod is far cheaper than a new heater. It will not save a tank that already leaks, but on a middle-aged unit it can add useful years.
Expansion tank and relief valve
A new heater should have a working temperature and pressure relief valve with a discharge pipe that runs to a safe spot. If your home has a closed plumbing system, where a backflow device or check valve stops water from flowing back into the main, heated water has nowhere to expand. An expansion tank takes up that extra volume and protects the heater.
Ask Veolia or the Union City construction office whether your service has a device that makes an expansion tank necessary.
Getting a tank out of a tight Union City building
Many Union City buildings are attached and dense, with the water heater in a basement corner, a utility closet or under a staircase. A full tank is heavy, and the old one must come out through stairs and narrow doors. We drain it first, cut it free and carry it out in pieces if needed.
Tell dispatch about stairs, ceiling height and who holds the key to the basement. If the heater serves several apartments, ask the super to open access.
Permit and inspection
The state construction code requires a permit for plumbing work on existing buildings, except ordinary maintenance. A heater swap is usually more than maintenance, but rules vary with fuel and location. Ask the Union City construction office what your job needs. For gas units, they may require an inspection after the work.
What affects replacement cost
The price is clear before work begins. The main drivers:
Insurance may pay for sudden water damage from a burst tank, but rarely for the heater itself. Photograph the damage, save the old tag and call your insurer before cleanup.

Call (551) 249-3045How a replacement day runs
Same-day replacement depends on stock and schedule.
Call and describe
Say what fuel the heater uses, where it sits and whether it leaks.
Choose the unit
The plumber advises on size and type and states the price.
Swap
Old tank drained and removed, new unit set, connected and vented.
Test
Controls, relief valve and flow are checked, and the old tank is hauled away.
Tank dead or leaking?
Call the 24/7 line. Shut the cold supply and heat source first, then tell dispatch what you found.
After the new heater is in
Mark the install date on the tank and plan to check the anode rod every few years. If the leak soaked a ceiling or wall, leak detection helps confirm the water is gone. Landlords next door in West New York reach the same line.
Water heater replacement questions in Union City
Dispatch answers around the clock. Same-day replacement happens when a matching unit and an open plumber line up. Otherwise we can make the area safe and return.
A leaking tank body means replacement. A failed small part on a young tank usually means repair.
Often, but it needs wiring and sometimes a new circuit. Tell the plumber early.
It depends on water, use and care. The serial number gives age, and the plumber can say how much life is left.
It depends on whether your plumbing is closed. Ask the plumber and the Union City construction office.
Yes. Removal is part of the job, including carrying it out of tight basements.
Still have a question? A dispatcher answers around the clock.
