You just wrestled a 150-pound steel cylinder out of your basement, and now it’s sitting in your driveway like a monument to bad decisions. The new water heater is installed. The old one? Nobody wants it. Your garbage hauler won’t touch it. The alley behind your house is starting to look like a scrap metal yard. You need a place to dump an old water heater, and you need one that won’t cost you a fortune or a fine.
This article walks you through every legal disposal route, what each one costs, and the prep work that makes the whole process easier. You’ll learn which places pay you, which places charge you, and which ones will take it for free. By the end, you’ll know exactly where that tank is going before you lift it again.
One quick note before we get into the weeds: if you’ve got kids around while you’re dealing with this project, a little distraction goes a long way. A book like How to Walk a Dump Truck has kept my own kids busy for a solid twenty minutes while I hauled scrap metal. Not a bad trade.
The Short Answer: Your Five Real Options
You don’t have as many choices as you’d think, but you have more than you realize. Here’s the honest breakdown of where an old water heater can actually end up.
- Scrap metal yard – Pays you by weight, usually $5 to $15 for a typical 40-gallon tank. Best financial outcome.
- City bulk pickup – Free or low-cost in most municipalities, but you’ll wait days or weeks and may need to schedule it.
- Retailer take-back – Many big-box stores and plumbing suppliers will haul away the old unit when they deliver the new one. Often free if you buy from them.
- Private junk haulers – Charge $50 to $150 but handle everything, including stairs. Worth it if you can’t lift it.
- Household hazardous waste facility – Some counties accept water heaters at their transfer stations. Check your local rules first.
Each route has its own quirks. Let’s dig into the details so you don’t show up somewhere and get turned away.
Scrap Yards: The Only Option That Pays You
If you want cash for your old tank, a scrap metal yard is the place. Water heaters are almost entirely steel, and steel has value. The catch is that most yards won’t take a water heater as-is. They need to see the inside.
Here’s the prep work that makes the difference between getting paid and getting rejected:
- Drain the tank completely. Open the drain valve at the bottom and let it run until nothing comes out. Tilt the tank to get the last few cups out. A tank with water in it is a hazard and many yards will refuse it.
- Remove the thermostat and any wiring. These are non-metal components that contaminate the scrap load. A flathead screwdriver pops most of them off in under a minute.
- Cut off the power cord. If you have an electric model, the cord and the heating elements inside need to go. Gas models have a gas valve and burner assembly that should be removed too.
- Call ahead and ask about the anode rod. Some yards want it removed because it’s magnesium or aluminum, not steel. Others don’t care. A quick phone call saves you a wasted trip.
Once you’ve done the prep, weigh the tank on your bathroom scale if you can manage it, or just guess. A typical 40-gallon tank weighs about 120 to 150 pounds empty. At current scrap steel prices of roughly $0.05 to $0.10 per pound, you’re looking at $6 to $15. Not retirement money, but it covers the gas to get there.
One thing I’ve learned the hard way: call the yard before you drive over. Scrap prices change daily, and some yards have different policies for painted steel versus clean steel. A water heater is painted steel, which is a lower grade than the clean stuff. Don’t be surprised if they quote you a lower rate than the sign out front says.
City Bulk Pickup: Cheap But Slow
Most cities and towns have a bulk trash pickup program that handles items too big for the regular bin. Water heaters qualify almost everywhere. The trade-off is timing and rules.
Here’s what you need to check with your local public works department:
- Is it scheduled or on-demand? Some cities have a specific week each month for bulk pickup. Others require you to call and request a pickup date.
- Is there a fee? Many municipalities include one or two bulk pickups per year in your property taxes or utility bill. Others charge $20 to $50 per item.
- Any prep requirements? Some cities require the tank to be drained and the doors removed. Others just want it curbside with no hazardous materials attached.
- Size limits? A standard 40-gallon tank is about 5 feet tall and 2 feet in diameter. That fits within most limits, but larger commercial tanks might not.
The biggest frustration with this route is the waiting. If your city only does bulk pickup on the second Tuesday of the month and you just missed it, that tank could sit in your garage for three weeks. Not ideal, but free is free.
Pro tip: check your city’s website before you drag the tank to the curb. Some cities have gotten strict about what counts as “bulk” and will slap a fine on you for putting out something they consider construction debris. A water heater usually falls under appliance disposal, which is a different category than construction waste.
Retailer Take-Back: The Easiest Route If You’re Buying New
If you’re replacing the water heater yourself, the store where you bought the new one might take the old one. Big-box home improvement stores and plumbing supply houses often have a take-back program for appliances. It’s not always advertised, so you have to ask.
Here’s how it typically works:
- You purchase a new water heater from the store.
- You bring the old one back to the store within a set time frame, usually 30 to 90 days.
- The store gives you a small credit or just accepts it for recycling.
The credit is usually modest, maybe $10 to $20, but the real value is not having to haul the tank to a scrap yard yourself. You’re already at the store buying the replacement, so the trip is free.
One caveat: not all stores participate. The big national chains have inconsistent policies depending on the location and the manager on duty. Call your specific store and ask for the appliance department, not the general customer service line. The person answering the phone at the front desk often doesn’t know the policy exists.
Also, some stores only accept the old unit if they delivered the new one. If you’re hauling the new one home yourself, they might not take the old one. Ask before you buy.
Private Junk Haulers: Paying for Convenience
Sometimes you just can’t do it yourself. Maybe the tank is in a crawl space with a 2-foot clearance. Maybe you’ve got a bad back and no one to help you lift. That’s where junk removal companies come in.
Companies like 1-800-GOT-JUNK and local independents will come to your house, haul the tank out, and dispose of it properly. The cost varies wildly depending on your location and how hard the pickup is. Expect to pay $75 to $150 for a single water heater. If it’s in a basement with narrow stairs, add another $50.
What you’re paying for is labor and liability. These guys have the dollies, the straps, and the insurance to move heavy objects without wrecking your floor or their backs. If you’ve ever tried to carry a water heater up a flight of stairs by yourself, you know this is money well spent.
The downside is that you have no control over where the tank ends up. Most reputable companies recycle the metal, but some just dump it in a landfill. If you care about recycling, ask the company what they do with appliances before you book them.
Comparison Table: All Five Routes at a Glance
Here’s a quick reference to help you decide which route fits your situation. Costs are estimates and vary by location.
| Method | Typical Cost | Time to Complete | Effort Required | Best For |
|---|---|---|---|---|
| Scrap yard | You get paid $5–$15 | 1–2 hours | High: draining, removing parts, hauling | DIYers who want cash |
| City bulk pickup | Free to $50 | 1–4 weeks waiting | Low: just set it curbside | People who aren’t in a hurry |
| Retailer take-back | Free, sometimes $10–$20 credit | Same day as purchase | Medium: load it in your vehicle | Anyone buying a new unit anyway |
| Private junk hauler | $75–$150 | Same day, scheduled | None: they do all the work | People with mobility issues or tight spaces |
| Household hazardous waste facility | Usually free | 1–2 hours including drive | Medium: load and unload | People whose county runs a transfer station |
Notice I didn’t include “leave it on the curb with a free sign” or “throw it in a dumpster behind a restaurant.” Both are illegal in most places and both are how people get fined. Don’t be that person.
What Not to Do: Three Mistakes That Cost People
I’ve seen plenty of people make a mess of this. Here are the three most common errors and how to avoid them.
Mistake #1: Not draining the tank completely. A 40-gallon tank holds 40 gallons of water, which weighs over 300 pounds. If you don’t drain it, you’re hauling 450 pounds instead of 150. Plus, most scrap yards and city pickup programs will refuse a tank that’s still full. Drain it the night before, let it sit open overnight, and drain it again in the morning. You’ll be surprised how much water comes out the second time.
Mistake #2: Assuming your regular trash hauler will take it. Standard curbside garbage pickup almost never accepts water heaters. They’re too heavy for the automated arms on the trucks, and they can damage the compactor. If you set it out with your regular trash, the hauler will leave it and might fine you for a violation. Call your hauler specifically to ask about bulk items.
Mistake #3: Cutting corners on prep because you’re in a hurry. A water heater that hasn’t been drained, with the wiring still attached, is a liability. Scrap yards will reject it, and some city programs will too. Take the ten minutes to do the prep work. It’s the difference between a smooth drop-off and a frustrating trip to a facility that turns you away.
Frequently Asked Questions
Can I put a water heater in a regular dumpster?
Technically yes, if you own the dumpster or have explicit permission from the dumpster owner. But if you’re talking about a shared dumpster at an apartment complex or a commercial dumpster behind a business, no. That’s trespassing and illegal dumping. Most rental dumpster companies also have weight limits and will charge you extra for a 150-pound steel tank. If you rented a dumpster for a renovation, toss it in. Otherwise, find another route.
Does Home Depot or Lowe’s take old water heaters?
It depends on the location and whether they delivered the new one. Home Depot’s installation service includes haul-away of the old unit, but if you bought the new one in-store and carried it out yourself, the policy varies. Lowe’s has a similar inconsistency. Call your specific store, ask for the appliance department manager, and get a straight answer before you load the old tank into your truck.
Can I sell my old water heater for scrap?
Yes, but the payout is small. A typical residential tank weighs 120 to 150 pounds empty, and scrap steel prices usually land around $0.05 to $0.10 per pound. That’s $6 to $15. You’ll get more if you separate the copper wiring and brass fittings, but those are minor components on a water heater. It’s not a money-maker; it’s a way to avoid a disposal fee.
Is it illegal to leave a water heater on the curb?
In most places, yes, unless you have scheduled bulk pickup. Leaving it on the curb outside of a scheduled pickup day is considered illegal dumping. Fines range from $50 to $500 depending on your city. If you’re not sure about your local rules, call the public works department and ask about bulk pickup scheduling before you drag anything to the curb.
What about the water heater’s insulation and lining?
Most water heaters have a foam insulation layer between the steel outer shell and the inner tank. Scrap yards accept this because it burns off during the smelting process. The glass lining on the inside of the tank is also not a problem for scrap yards. The only things you need to remove are the external wiring, thermostat, and gas components if it’s a gas model. Leave the insulation alone; it’s not worth the effort to remove it.
What to Do Right Now
You’ve got the information. Here’s the action plan, in order of preference.
- If you’re buying a new water heater, ask the retailer about take-back before you pay. That’s the easiest route.
- If you’re not buying new, call your city’s public works department and ask about bulk pickup. Schedule it even if it’s weeks out.
- If you want cash and you’re physically able, prep the tank and take it to a scrap yard. Call first to confirm they accept water heaters.
- If you can’t lift it or it’s in a terrible spot, hire a junk hauler. It costs more, but it’s done in an afternoon.
- Never leave it on the curb without a scheduled pickup. Never put it in someone else’s dumpster. Never let it sit in your yard for a month.
One last thing: if you’re replacing the water heater yourself, take a photo of the old unit’s data plate before you haul it away. The model number and manufacture date are useful if you need to match the new unit’s dimensions or connections. It’s a small step that saves a lot of frustration later.
Now go get that tank out of your driveway. You’ll feel better when it’s gone.
