Tackling water heater removal on your own can be a smart way to save money—if you know what you’re doing. Done wrong, it can lead to leaks, gas hazards, electrical shocks, or even flooding inside your home. This guide walks you step-by-step through the process, explains when to call a pro, and shows you how to stay safe and compliant with local codes while keeping costs under control.
Should You Remove a Water Heater Yourself?
Before you grab your tools, decide whether DIY removal is appropriate for your situation.
When DIY Water Heater Removal Can Make Sense
You may be a good candidate for DIY if:
- Your existing unit is easily accessible (garage, basement, utility room).
- You’re comfortable shutting off water, gas, or electricity.
- You have basic hand tools and can lift or move heavy objects safely.
- You’re replacing like-for-like (e.g., old tank for new tank in same location).
In these cases, removing the old unit yourself can shave a significant amount off the total cost of a new installation.
When You Should Call a Professional
Hire a licensed plumber or HVAC contractor if:
- You smell gas or see signs of a gas leak.
- The heater is in a tight attic or crawlspace.
- You’re switching fuel types (electric to gas or vice versa).
- There’s corrosion on gas lines, valves, or electrical connections.
- Local building codes require a licensed pro for disconnection.
If in doubt, get at least one quote. Safety and code compliance matter more than saving a few dollars.
Safety First: Hazards of Improper Water Heater Removal
A water heater is more than just a big tank. It’s tied into multiple critical systems in your home, and improper water heater removal can create real hazards.
Common Risks
- Scalding and burns from hot water during draining.
- Flooding if the tank or lines rupture or if you skip proper draining.
- Gas leaks and explosions if gas lines are mishandled.
- Carbon monoxide issues if venting is disturbed on gas models.
- Electrical shock or fire with electric heaters.
- Back strain or injury from moving a heavy tank without help.
Always:
- Wear gloves and eye protection.
- Let the tank cool before draining if possible.
- Use two people or a dolly to move the heater.
- Keep children and pets away from the work area.
For gas and electrical safety guidelines, the U.S. Consumer Product Safety Commission is a reliable reference (source: CPSC).
Tools and Materials You’ll Need
Gather everything before you begin the removal process.
Basic tools:
- Adjustable wrench and/or pipe wrench
- Screwdrivers (flathead and Phillips)
- Pliers
- Utility knife
For disconnection and draining:
- Garden hose (for tank drain)
- Bucket or shallow pan (to catch residual water)
- Towels or rags
- Teflon tape (if you’re capping lines)
Safety and moving equipment:
- Work gloves and safety glasses
- Appliance dolly or hand truck
- Straps for securing the tank
Optional but helpful: a helper, flashlight or headlamp, and a wet/dry vacuum for small spills.
Step-by-Step Guide: How to Remove a Water Heater Safely
Follow these steps for a standard tank-style water heater. Always consult the manufacturer’s instructions and local codes.
1. Turn Off Power or Gas
For electric water heaters:
- Locate your main electrical panel.
- Turn off the breaker labeled for the water heater (usually 240V, double-pole).
- Use a non-contact voltage tester at the heater’s electrical connection to confirm power is off.
For gas water heaters:
- Locate the gas shutoff valve on the gas line near the heater.
- Turn the valve so it’s perpendicular (crosswise) to the pipe to close it.
- If your heater has a gas control knob, turn it to OFF or PILOT per the label.
If at any point you smell gas, stop and call your gas utility or a licensed professional.
2. Shut Off the Water Supply
- Find the cold water shutoff valve on the pipe entering the top of the heater.
- Turn the valve clockwise until it stops.
- Open a hot water faucet somewhere in the house (a sink or tub) to relieve pressure and allow air into the lines.
This step prevents water from continuing to fill the tank while you’re removing it.
3. Drain the Tank Completely
Draining is essential for safe and clean water heater removal.
- Attach a garden hose to the drain valve at the bottom of the tank.
- Run the other end of the hose to a floor drain, sump pit, outdoor area, or large container.
- Open the drain valve; use a flathead screwdriver if needed.
- Open the pressure relief valve or a nearby hot water faucet to let air in and speed drainage.
Tips:
- If the tank is full of hot water, let it cool for a few hours or overnight to reduce burn risk.
- Sediment can clog the drain valve; gently tap the hose or use a small screwdriver (carefully) at the valve opening if draining slows.
- Never leave the draining process completely unattended; check periodically for leaks and proper flow.
4. Disconnect Electrical or Gas Connections
Disconnecting an Electric Water Heater
- Remove the access panel on the junction box at the top of the heater.
- Confirm power is OFF with a voltage tester.
- Loosen wire nuts connecting house wiring to heater wiring.
- Separate the wires and cap the house wires with new wire nuts.
- Gently pull the electrical cable away from the heater.
Disconnecting a Gas Water Heater
- Ensure the gas valve at the line is OFF.
- Use two wrenches to disconnect the flexible gas connector from the control valve, supporting the gas line so you don’t stress it.
- Cap or plug the gas line if required by local code (some areas require a licensed pro for this).
Never reuse a damaged or kinked gas flex connector on your new heater—replace it.
5. Disconnect Water Lines
Most modern heaters use flexible copper or braided steel connectors; older ones may be hard-piped.
- Use an adjustable wrench to loosen the nuts on the hot and cold water connections at the top of the tank.
- Have a towel or small bucket ready to catch remaining water.
- If the heater is hard-piped:
- You may need to cut the pipes using a tubing cutter or hacksaw.
- Leave enough straight pipe for reconnection or for your installer.
Mark which line is hot and which is cold if it’s not obvious; this helps during new installation.
6. Disconnect Venting and Other Attachments
For gas water heaters:
- Locate the vent pipe at the top of the heater.
- Remove any screws or fasteners holding the vent in place.
- Carefully lift the vent off and set it aside.
- Inspect vent components for corrosion if you plan to reuse them.
For seismic straps or brackets (common in earthquake-prone regions):
- Remove any screws or bolts securing the tank to the wall.
- Keep hardware if it’s in good condition and compatible with the new unit.
7. Remove the Old Water Heater
Once all utilities and connections are disconnected and the tank is drained:
- Verify the tank is empty by gently rocking it—there should be no sloshing.
- Clear a path to the exit.
- Slide an appliance dolly under the tank; strap it securely.
- Tilt the tank back slightly and carefully wheel it out of the area.
- Use ramps or assistance for stairs or uneven surfaces.
Even empty, a standard 40–50 gallon tank can weigh 100+ pounds. Do not attempt to carry it solo if you’re unsure of your ability.
What to Do With an Old Water Heater: Disposal and Recycling
Responsible water heater removal doesn’t end at your garage door. You need a plan for disposal.
Disposal Options
- Municipal bulk pickup: Many cities offer bulk waste collection for large appliances. Check your local guidelines for scheduling and preparation requirements.
- Metal recycling centers: Water heaters contain steel and other recyclable metals. Some scrap yards may even pay a small amount for the metal.
- Retailer or installer haul-away: When buying a new heater, ask if haul-away of the old unit is included or available for a small fee.
- Landfill or transfer station: As a last resort, take it to an approved disposal site that accepts large appliances.
Before taking it anywhere, make sure it’s fully drained to prevent leaks in your vehicle.
How Much Does Water Heater Removal Cost?
Understanding typical removal costs helps you decide whether DIY or professional service makes more sense.
Typical Professional Removal Fees
- Standalone removal: $75–$200, depending on location and difficulty.
- Removal as part of new installation: Often included or charged as $50–$150 line item.
- Complex scenarios: Hard-to-access locations, code issues, or hazardous conditions can raise costs.
How DIY Saves Money—And Where It Doesn’t
Doing your own water heater removal can save that $100–$200 fee, but keep these potential costs in mind:
- Replacing damaged gas or water lines if you make a mistake.
- Repairing water damage from improper draining.
- Fines for improper disposal in areas with strict regulations.
- Health or injury costs from unsafe lifting or electrical work.
If your main reason to DIY is budget, consider handling only the safe tasks—like draining the tank and moving it to the garage—while letting a pro handle gas and electrical work.
