Removing a geyser means working directly with plumbing and, for gas models, gas line connections — which is why it’s generally recommended to bring in a qualified plumber or electrician rather than treating it as a straightforward DIY job. For anyone with the relevant experience, though, here’s how the process actually works, step by step.
Tools Needed
Before starting, gather: flathead and Phillips screwdrivers, an adjustable wrench, a pipe wrench, a pipe cutter (if pipes are soldered rather than threaded), thread sealant, a drain hose or bucket, and a voltage tester.
Step 1: Shut Off Power or Gas
Cut off the relevant supply completely before touching anything else — electrical power at the breaker for an electric geyser, or the gas valve feeding the unit for a gas model. This is the non-negotiable first step regardless of geyser type.
Step 2: Drain the Tank Fully
Connect a hose to the drain valve at the bottom of the unit and let it empty completely, either into a bucket or outside. A full tank is significantly heavier and more awkward to handle, so draining first makes the physical removal safer and avoids water spilling mid-process.
Step 3: Disconnect the Electrical Connection (Electric Geysers)
Remove the cover plate on the electrical connection box, and use a voltage tester to confirm there’s genuinely no power running through the wires before disconnecting them from the terminal block. Noting how the wires were connected makes reinstallation — whether for a new unit or a repair — considerably easier.
Step 4: Disconnect the Water Pipes
Using an adjustable wrench and pipe wrench, carefully detach both the inlet and outlet water pipes. If the pipes are soldered rather than threaded, a pipe cutter will be needed instead. Keep towels or a bucket nearby for any residual water still in the lines.
Step 5: Disconnect the Gas Line (Gas Geysers Only)
This step should specifically be handled by a qualified technician. The gas line needs to be properly capped once disconnected — an improperly sealed line left open, even temporarily, is a genuine safety hazard rather than a minor oversight.
Step 6: Remove the Unit
Carefully slide the geyser out of its mounting bracket or straps. Geysers are heavier than they look once removed from the wall, so having a second person to help support the weight is worth arranging in advance rather than attempting it alone.
Step 7: Cap and Seal the Connections
Once the unit is out, cap or seal the water pipe connections using the appropriate fittings and thread sealant to prevent leaks — this matters even if a replacement unit is going in shortly after, since gaps in timing can otherwise mean an unsealed line sitting exposed.
Disposal
Dispose of the old unit according to local regulations, which in some areas require water heaters to be recycled or disposed of through a specific process rather than standard waste collection.
If You’re Replacing the Unit
When removal is happening because a new geyser is going in, it’s generally safer to have the same technician handle both the removal and the new installation in a single visit. That avoids any gap where gas or water connections are left capped, or aren’t reconnected consistently between two separate jobs.
How to Safely Uninstall a Gas or Electric Geyser
- Turn off the power or gas supply: Switch off electrical power at the breaker, or close the gas valve feeding the unit, before doing anything else.
- Drain the tank fully: Connect a hose to the drain valve and empty the tank completely to reduce weight and avoid water spilling during removal.
- Disconnect water inlet and outlet pipes: Use appropriate tools to detach the plumbing connections, having towels or a bucket ready for residual water.
- Disconnect the gas line (gas models only): This step should be handled by a qualified technician, who will properly cap the gas line to prevent leaks.
- Remove the mounting bracket and unit: Carefully detach the geyser from its wall mount or stand, with a second person helping to support its weight.
- Dispose of or store the unit safely: Old geysers may contain residual water and, for gas models, should be handled by someone aware of any remaining gas line considerations.
Frequently Asked Questions
Can I uninstall a geyser myself?
For gas geysers, uninstallation involves disconnecting a gas line and should be done by a qualified technician; for electric geysers, disconnecting power and plumbing is more accessible but still carries risk if you're not familiar with the connections.
What should I do before uninstalling a geyser?
Turn off and disconnect the power or gas supply first, drain the tank fully to reduce weight and prevent water damage, and have a plan for safely disposing of or storing the old unit.
Is it safe to leave a gas line capped after removing a geyser?
Yes, as long as it's capped properly by a qualified technician — an improperly sealed gas line left disconnected is a serious safety hazard and should never be left open or loosely capped.
Should I uninstall my old geyser myself if I'm replacing it with a new one?
It's safer to have the same technician handle both the removal of the old unit and installation of the new one in a single visit, ensuring gas and water connections are properly capped and reconnected without gaps.
