Most homeowners replacing a water heater get a surprise: the plumber installs the new one and leaves the old tank sitting in your garage. That’s not the plumber being lazy — most simply don’t offer haul-away as part of the job. So now you’ve got a 150-pound steel tank and no clear plan for it.
Figuring out how to dispose of an old water heater is more involved than tossing it at the curb, but it’s far from complicated once you know your options.
Can You Put It Out for Bulky Item Pickup?
Sometimes — but don’t count on it. Many municipal bulky item programs do accept water heaters, but they often require you to call ahead, schedule a specific pickup day, and drain the tank completely first.
Some programs limit what they’ll take. If you’re in a city with strict bulky item rules, you may hit a wall fast. For example, certain California cities cap how many large items they’ll collect per pickup, which means a water heater might not make the cut alongside other furniture or appliances you’re clearing out.
Check your city’s waste management website before assuming curbside will work. If scheduling is a hassle or your municipality doesn’t accept it, you have better options.
Water Heater Recycling Options
Water heaters are largely recyclable. The steel tank, copper pipes, and aluminum components all have real scrap value. Many scrap metal yards will take an old water heater — some even pay you a small amount depending on current metal prices.
Before dropping it off, drain all the water out and disconnect any remaining fittings. Call ahead to confirm the yard accepts water heaters, since not every facility handles appliances the same way.
Some appliance retailers and HVAC supply stores also have recycling programs, especially if you’re purchasing a replacement unit through them. It’s worth asking at the point of sale.
Selling or Donating a Working Unit
If your water heater still functions but you’re upgrading — say, switching from a tank to a tankless model — it might have a second life. Habitat for Humanity ReStores sometimes accept working water heaters, and Facebook Marketplace or Craigslist can move them surprisingly fast, often free to anyone willing to pick it up.
Be honest about the unit’s age and condition. A 12-year-old heater near the end of its expected lifespan isn’t worth much, but a 5-year-old tank in good shape could genuinely help someone in a pinch.
Hiring a Junk Removal Service
For most homeowners, hiring a water heater removal service is the simplest path. A crew comes to your home, disconnects and lifts the tank, loads it onto their truck, and handles disposal or recycling for you.
The junk removal water heater cost typically runs between $75 and $150 for a single unit, though prices vary based on your location, the size of the heater, and whether any additional items are being removed at the same time.

The real value isn’t just the hauling — it’s that you don’t have to drain it yourself, wrestle it down a flight of stairs, or rent a truck. For many people, that’s worth every dollar.
DIY Removal vs. Professional Hauling
DIY makes sense if you have a truck, a helper, and access to a scrap yard. A 40-gallon water heater can weigh 120–150 pounds empty, and that’s before factoring in tight hallways or basement stairs.
Professional hauling makes sense when you’re short on time, don’t have the right vehicle, or just cleared out an attic and don’t want one more project. If you’re also dealing with an old dryer or other appliances, combining items into one pickup almost always saves money — similar to how disposing of an old dryer works best when bundled with a larger haul.
Quick Checklist Before You Schedule Pickup
- Drain the tank completely — open a hot water faucet inside and connect a hose to the drain valve
- Disconnect the gas line or electrical connection if not already done
- Check if your city’s bulky pickup will accept it and what the scheduling lead time is
- Call your local scrap yard to confirm they accept water heaters
- If hiring a junk removal service, ask whether they recycle or responsibly dispose of the materials
Old water heater disposal doesn’t have to be a logistical headache. Whether you drop it at a scrap yard, donate a working unit, or book a junk and debris removal crew, there’s a straightforward option for every situation. The key is knowing what’s available before the old tank is already blocking your utility room.
