Step 1: Drain It First
Before any disposal method, you must drain the tank:
- Turn off the gas or electricity to the water heater
- Turn off the cold water supply valve
- Connect a garden hose to the drain valve at the bottom
- Run the hose to a floor drain, utility sink, or outside
- Open a hot water faucet somewhere in the house to allow air in
- Open the drain valve and wait — a full tank takes 20–40 minutes to drain
Disposal Options
| Option | Cost | Notes |
|---|---|---|
| Municipal bulk item pickup | Free (by appointment) | Check your city's waste management website |
| Plumber haul-away (with install) | Usually free or $25–50 | Most plumbers include haul-away when installing new unit |
| Scrap metal yard | Earn $10–25 | Must transport yourself; drain first |
| Junk removal company | $75–$125 (minimum) | Most convenient; they carry it out |
| Utility rebate programs | Free + possible rebate | Some utilities offer appliance recycling — check yours |
Check Your Plumber First
If you're having a new water heater installed, ask the plumber or HVAC contractor if they include haul-away. Most do — either for free or a modest charge — because they have a truck and already know the disposal route. This is the simplest option and avoids a second call entirely.
Utility Recycling Programs
Some utility companies run appliance recycling programs that pick up old water heaters, refrigerators, and washers for free — sometimes with a $25–50 rebate. Check your electric or gas utility's website under "appliance recycling" or "energy efficiency programs."
Scrap Metal Value
A standard tank water heater contains steel, some copper in the heating element and fittings, and sometimes brass valves. At current scrap metal prices:
- 30-gallon tank (~60 lbs): $6–15 in scrap
- 50-gallon tank (~100 lbs): $10–25 in scrap
- 80-gallon tank (~140 lbs): $14–35 in scrap
Scrap value is minimal — worth knowing, not worth optimizing for.
Frequently Asked Questions
Can I put an old water heater at the curb?
Many municipalities allow water heaters as bulk item pickups, but you must schedule it — you cannot simply leave it at the curb unannounced. Check your city or county waste management website to schedule a bulk item pickup day.
What is an old water heater worth in scrap?
A standard 40–50 gallon water heater weighs 60–120 lbs and contains steel, copper, and sometimes brass. At scrap prices of $0.10–$0.20/lb for steel, expect $10–25 in scrap value. Not worth a special trip, but offsets cost if removing yourself.
Will junk removal companies take a water heater?
Yes. Most junk removal companies accept water heaters. Expect a minimum charge of $75–$125 for a single water heater. When bundled with other items, the marginal cost is lower.
Do I need to drain the water heater before removal?
Yes. A full 50-gallon water heater weighs 400+ lbs with water. Drain it completely before any junk removal pickup or transport. Connect a hose to the drain valve and run it to a floor drain or outside.
Can tankless water heaters be disposed of the same way?
Tankless water heaters are smaller and lighter but may contain electronic components. Most junk removal companies accept them. Some components may qualify for e-waste recycling. Check with your local recycling center.
