The installed price of a 40 gallon water heater in Lodi has two parts: the tank and everything it takes to connect it safely. Many people compare the tank price and forget the rest, then find the quotes do not match. This guide breaks the job into its parts so you can compare any quote line by line.
We do not print a single dollar figure here, because the number depends on your fuel, your venting and your basement, and a figure that ignores those would mislead you.
A 40 gallon tank suits a household of about two to four people when showers are staggered. It is the size many homes already have, which is why a like-for-like swap is the most common job. If your family has grown, or you run a soaking tub, a larger tank or a different type may serve better.
What a quote should include
A complete installed price covers the work around the tank as well as the tank itself. Ask whether each of these is in the number:
| Line item | What it covers | Ask this |
|---|---|---|
| The heater | The 40 gallon tank, gas or electric | Which model, and what is the warranty |
| Labor | Draining, removing, setting and connecting | Is a second plumber needed to carry it |
| Connections | New flexible lines, shutoff valves, unions | Are shutoffs and unions included |
| Safety parts | Relief valve and discharge pipe | Is the discharge piped to code |
| Expansion tank | Needed on closed systems | Does my system need one |
| Venting or circuit | Flue work for gas, breaker and wire for electric | Does the vent need changes |
| Removal | Haul-away of the old tank | Is disposal included |
| Permit | Fee and inspection if required | Who pulls it and who pays |
When two quotes differ by a large amount, the gap is usually in this table. A low price often leaves out unions, an expansion tank or haul-away. A high price may include a premium tank or work your house does not need.
Gas or electric changes the job
A gas heater needs a gas line, a flue and combustion air. If the existing flue is sound and the connections match, a swap is simple. If the flue is corroded, undersized or routed badly, it must be corrected, and that adds parts and time. A gas heater also needs a leak test after the connection.
An electric heater needs a properly sized circuit and breaker, and the plumber checks that the wiring is in good condition. Electric tanks are simple to swap but cost more to run in most homes, and that matters over a decade. Our installation page compares the types.
Why the 40 gallon label is not enough
Two heaters with the same gallon number can perform differently. The first-hour rating on the yellow label says how much hot water the heater can deliver in a busy hour, and it depends on the burner or element size. A gas 40 gallon tank usually has a higher first-hour rating than an electric 40 gallon tank. Compare that number against your busiest morning, not just the capacity.
Efficiency also varies. A higher efficiency unit costs more up front and less to run. The label shows an annual cost estimate, which helps you compare two models without guessing.

Ask each plumber the same list:
- Is the quote for the exact model, and can I see the label?
- What is included in the price: shutoffs, unions, expansion tank, relief valve and discharge pipe?
- Does it include removing and disposing of the old heater?
- Does the venting or circuit need changes, and are they priced?
- Who handles the permit and inspection, and is the fee included?
- What does the warranty cover on parts and labor, and who honors it?
A plumber who answers clearly is a good sign. Vague answers are a reason to ask again.
When replacement beats repair
A heater with a leak from the tank body cannot be repaired. If the unit is old and has scale, repeated failures or a rusted base, replacement usually costs less over time than another repair. If it is young and a single part has failed, repair is often right. The water heater repair page helps you tell which side you are on.
What Lodi water does to a 40 gallon tank
The Passaic Valley Water Commission's 2026 water quality report for Lodi lists hardness of 106 to 242 ppm at the Little Falls plant, and 42 ppm in the Wanaque water blended in for most customers. Hardness in the upper range leaves scale on the bottom of a tank and on electric elements, which makes the heater work harder and shortens its life.
If you live in Hackensack, Hasbrouck Heights, Maywood or Wood-Ridge, the Veolia Hackensack system reports a highest hardness of 210 ppm.
Practical result: a flush valve and unions at the heater, plus a yearly flush, are cheap protection. We cover customers in Hackensack and Hasbrouck Heights as well, and the same advice applies there. The report is posted by PVWC if you want to check the figures.
What can raise the price on the day
Surprises are usually in the space around the heater:
- A corroded gas line or flue that needs replacing.
- Shutoff valves that will not close and must be replaced to isolate the heater.
- A tight closet that makes removal and setting slow.
- Stairs that require extra labor to carry the old and new tank.
- An outdated electrical circuit that must be upgraded.
A good plumber tells you about these before the job. If something new appears once the old heater is out, you hear about it before more work is done.
Cost questions about a 40 gallon install
Does the cost change if the heater is in the basement or an upstairs closet?
Yes. Stairs and tight spaces add labor, and an upstairs heater needs a drain pan and a discharge line that reaches a safe point. The plumber looks at the location before quoting.
Is a bigger tank always better?
No. A larger tank wastes energy keeping extra water hot. Pick the size that matches your busiest hour of use, and check the first-hour rating.
Can I switch from gas to electric to save on installation?
Sometimes, but electric costs more to run in many homes, and the circuit must be able to carry the load. Compare running cost, not only installation cost.
Is a permit needed for a water heater swap in Lodi?
Possibly. The borough website lists a Building Department page, and the plumber tells you what applies to your address before starting.
Does a hard water supply change which heater I should pick?
It does not change the type, but it changes the care. Ask for service valves, and plan a yearly flush if your water is in the harder part of the PVWC range.
