Water heater replacement is the full swap of a failed or failing heater: shutting off and draining the old unit, hauling it out, setting the new one, and reconnecting water, fuel, venting and safety devices. Most households learn they need one on the worst morning, with a cold shower or a wet utility room. Our licensed plumbers answer the 24/7 emergency line around the clock, and same-day appointments are offered when available.
A good replacement is more than a like-for-like swap. The old install may have skipped an expansion tank, used a short vent run, or left no drain pan. We check those items against the National Standard Plumbing Code, then give you a clear price before work starts.
Heater dead or flooding the utility room right now?
Close the cold water valve above the heater first. If water is pouring out, switch the heater off at its breaker only when the panel is dry and you are not standing in water. Otherwise stay out and call us.
If you smell gas, leave the building and call the gas utility or 911 before you call a plumber. A cold shower can wait, a gas leak cannot. Once the building is cleared, call (732) 466-1098 and tell us the fuel type, tank size and where the leak starts.
Replace now or repair once more
A leak from the tank shell ends the debate, since steel that has rusted through cannot be patched. Water at a fitting, valve or element flange is a different story and often a repair, which is why we look before quoting.
Age, repeat failures and a rusty bottom all push toward replacement. If you are leaning the other way, our page on water heater repair explains which parts are worth saving.
Tank, tankless or hybrid: what each asks of you
The right unit depends on your house, your fuel and your habits. Here are the real trade-offs.
| Option | Fits when | What it costs you |
|---|---|---|
| Standard tank, gas | Venting and gas line already in place | Standby heat loss, a flue to maintain. |
| Standard tank, electric | No gas service or no good flue path | Slower recovery, higher electric load. |
| Hybrid heat pump tank | Space with room for airflow and a drain | More height, noise, cooler surrounding air. |
| Tankless | Big households or tight closets | Gas line and vent upgrades, scale care. |
Choosing tankless often changes the gas line and the vent, so read our tankless water heater page before deciding.

Sizing: 40, 50, 75 and the first-hour rating
Tank size is only half the story. The first-hour rating tells you how much hot water the unit delivers in the first sixty minutes when full and hot, and it is printed on the yellow label.
40 gallons
Fits one or two people with modest demand. Two showers back to back may drain it.
50 gallons
The common choice for a family home. A 50 gallon water heater covers most mixed use without needing a larger closet.
75 gallons
Suits large households or soaking tubs. It needs more floor space and a bigger fuel load.
Match the first-hour rating
Add up your busiest morning's fixtures. If the rating falls short, size up or consider a second unit.
What a proper swap includes beyond the tank
These items are where cheap replacements cut corners.
- Gas line and shutoff check, including a leak test at the new connection.
- Venting inspected for slope, joints and clearances, and corrected if it fails.
- Expansion tank sized and installed on closed systems, with air pressure set.
- Drain pan with a pipe to a safe drain or outdoor termination.
- Temperature and pressure relief valve with a full-size discharge pipe.
- New water connectors and shutoff valve, not reused fatigued ones.
- Old unit removed and hauled away.
Permits and inspection in Neptune Township
Permit rules vary, so ask the Neptune Township construction office what your replacement needs. The office has a Plumbing Subcode Official and an online permit portal. The township's 2018 fee schedule lists $27 per fixture or device, including water heaters up to 99 gallons, and $65 for a heater of 100 gallons and up. Confirm current fees with the office.
Inspections must be requested at least 24 hours ahead, and the township says it performs them within three business days of the requested time. Plan for that gap, because an unpermitted install can create trouble at resale. For planning a brand-new location instead, see water heater installation.
How a replacement day runs
Each step below ties to the heater, not to a generic job list.
Isolate
We close water, power or gas, and open a hot tap so the tank can drain.
Drain and disconnect
A hose carries the water to a drain, then lines, vent and relief piping come off.
Set and level
The new unit goes on the pan, and any failed venting or supply piping gets corrected.
Fill and purge
The tank fills with a hot tap open to push out air, then we check every joint for drips.
Fire and test
We light or energize the unit, check flue draw or element power, and set the temperature in the 120 to 140 degree F range.
Same-day replacement when available
We offer same-day appointments when available, and the emergency line is open at all hours. Availability depends on stock, the unit type and how much venting or gas work the job needs. A standard tank swap is simpler to turn around than a tankless conversion.
We do not promise an arrival time. We do tell you what the job involves and what it costs before work starts, whether you live in Neptune or in Asbury Park.
Warranty, explained in general terms
Tank heaters usually carry a manufacturer warranty on the tank and a shorter one on parts, and labor is often a separate matter. Read the actual terms on the unit you choose, since coverage varies by brand and model. Warranties generally expect proper installation, and some ask for regular maintenance, so keep your paperwork.
What 72 to 140 ppm water means for the new tank
New Jersey American Water reports hardness of 72 to 140 ppm in its Coastal North system, about 4 to 8 grains per gallon, and your street may sit anywhere in that range. Heated hard water drops scale inside a tank.
The payoff: ask your installer about flushing, anode rod condition and a drain valve you can reach. Those small choices stretch the life of the next heater, which matters just as much in Neptune City.
What drives the price of a replacement
Two houses with the same tank size can get very different totals. These are the reasons.
If a leak damaged the home, photograph it and tell your insurer or landlord. Coverage is their call, but we can provide an itemized invoice.
Water Heater Replacement questions in Neptune, NJ
Yes. The 24/7 emergency line is open around the clock, so call (732) 466-1098 at any hour. Tell us the fuel, the tank size and whether it is leaking.
While you wait, close the cold supply valve above the heater and stay clear of wet electrical areas. If you smell gas, leave and call the gas utility or 911 first. We give a clear price before work starts and do not promise an arrival time.
Count the fixtures that run at once on your busiest morning and compare that to the unit's first-hour rating. A 50 gallon water heater is common for families, 40 gallons for one or two people, and 75 gallons for large households or big tubs.
We size it with you on the call, based on the people in the home and the fuel you already have.
Yes, but it is a bigger job. Gas to electric needs a dedicated circuit and may leave the old flue unused. Electric to gas needs a gas line, a flue and combustion air.
We review the panel, gas service and vent path first, then give you a clear price before work starts.
Permit rules vary, so ask the Neptune Township construction office. The township's 2018 fee schedule lists $27 for a water heater up to 99 gallons and $65 for 100 gallons and up. Confirm current fees with the office.
Inspections must be requested at least 24 hours ahead, and the township performs them within three business days of the requested time.
We remove it and haul it away as part of the job. Before it leaves, we check the old unit's label for the model and age, which helps explain what failed and what to ask for next time.
Check your lease and tell your landlord or property manager right away, since the responsibility usually sits with the owner. Take photos and note when the problem started.
With your permission we can speak to the landlord and send a written finding and itemized invoice.
Maybe. Tankless suits large households and tight closets, but it often needs a larger gas line, a new vent and regular descaling, which matters with Neptune's moderately hard water. Compare it against a new tank before you decide.
