What a 40 gallon swap usually covers
A 40 gallon tank is the common size for a small to mid-size home, and it is the one people usually mean when they ask about an installed cost. The price you are quoted should cover more than the tank. It should cover the labour, the fittings and the haul-away of the old unit.
Most swaps follow the same pattern. The water and gas or power are shut off, the old tank is drained and disconnected, and the new one is set, connected and tested. What varies is what the plumber finds when the old tank comes out.
Corroded fittings, a failed shutoff valve or an old vent pipe are common surprises. None of them is certain on your job, but a good quote tells you how each would be handled and what it would add before anyone starts cutting.
- Draining and disconnecting the old tank
- Setting and leveling the new tank
- New flexible connectors and a shutoff on the cold line when the old ones are worn
- A relief valve and discharge pipe where they are missing or undersized
- Venting and gas or electrical connections checked and tested
- Removal of the old tank
Is 40 gallons enough for your household?
Size is the first question to settle before price, because a tank that is too small costs you every morning and a tank that is too large costs you in standby heat. Ask the plumber to size it with you rather than copy the old label.
The table below is a rough guide for talking it through. It is not a sizing calculation, and the U.S. Department of Energy publishes sizing guidance that a plumber can walk you through.
| Household | Does 40 gallons fit? | What to consider |
|---|---|---|
| One or two people, one bathroom | Usually yes | Showers at different times keep the tank from running cold |
| Three people, one or two bathrooms | Often yes | Dishwasher and laundry running during showers can drain it |
| Four or more people, heavy morning use | Often tight | Ask about a larger tank or a unit with a faster recovery rate |
| Large soaking tub or multiple showers at once | Usually no | A bigger tank or a tankless unit may suit the demand better |
If the old heater always ran out of hot water, do not copy its size by default. Tell the plumber how the household actually uses hot water and let the size follow from that.
A like-for-like swap still involves paperwork. According to the New Jersey Department of Community Affairs, replacing a water heater with one of the same capacity is minor work, and the local enforcement agency must be notified.

Want a real number for your basement or closet? Call and describe the heater you have now.
(732) 466-1098What moves the final price
Two homes can buy the same 40 gallon tank and still get different totals. These are the things that change the number, in the order they tend to matter.
Whether your homeowners insurance helps depends on why the old tank failed. Policies often cover sudden water damage but not wear, so ask your insurer before you assume either way. For a real number, call us, describe the heater and the space, and ask for the price in writing before work starts.
Does a New Brunswick water heater swap need a permit?
We have not verified the New Brunswick rule on permits for replacing a water heater, so we are not going to guess. Permit rules for like-for-like swaps differ between towns and can change.
The practical step is simple. Call the New Brunswick building or construction office and ask whether a permit and inspection are required for a water heater replacement at your address. Ask who pulls the permit, and whether any inspection needs to be scheduled afterward.
A plumber you hire should be able to tell you, but it is worth confirming for yourself, especially if you rent or live in a multi-unit building where the owner may need to be involved.

A short checklist before the old tank comes out
A few minutes of preparation makes the visit smoother and keeps the area safe.
One item belongs on that list. The state Department of Community Affairs code alert says a like-for-like water heater replacement still needs a permit through the town, so ask whoever quotes the job who is handling it.
- Find the shutoffsLocate the main water valve and, on a gas heater, the gas shutoff near the unit. Turn the water valve clockwise to close it.
- Clear the spaceMove boxes and stored items at least an arm's length back from the heater so the plumber can work and carry the old tank out.
- Note the old labelPhotograph the rating plate on the old heater. It shows fuel type, size and model, which helps with a phone price.
- Check for water on the floorIf the tank is leaking, shut the water valve and keep clear of any electrical item standing in water. On an electric heater, switch off the breaker if the panel is dry and safe to reach.
- Smell gas? LeaveIf you smell gas near a gas heater, leave the building and call the gas utility or 911 before anything else.

Reading two written quotes side by side
A cheaper quote is not always a smaller job, and a higher one is not always padded. Ask each plumber what is included, and what is listed as extra. Items like the haul-away, new connectors and venting changes are the usual gaps.
If your current tank has failed and you are weighing a different type, a tankless water heater has a different installation scope and a different price structure from a tank swap. That is a separate conversation from this one.
Standby heat is also worth a thought. A tank keeps its water hot all day, so a larger tank than you need quietly wastes energy, while a smaller one runs out. The goal is the size that matches how your household really lives.
Neighbors in Edison and Highland Park ask us the same questions, and the answer is the same. The honest price comes from seeing the tank, the venting and the space, either in person or through clear photos.
Frequently asked questions
Sometimes, if showers are spread out and the dishwasher and laundry do not run at the same time. Heavy morning use often calls for a larger tank or a faster recovery rate, so size it with your plumber.
The difference is usually in scope. Venting, new connectors, code related parts, haul-away and permit handling may be in one quote and left out of the other. Ask each to list what is included.
Many straightforward swaps are done in a part of a day, but venting, access and surprises behind the old tank can add time. Your plumber can tell you more once they see the space.
A phone price is possible when you can give the fuel type, tank size, location and venting. Clear photos of the rating plate and the surrounding space help. The final price is confirmed in writing before work starts.
