Hot water tanks are anchored by straps or strips of perforated metal called plumber’s tape. These anchors, usually secured to wall studs behind the water tank, keep the tank secure in case of an earthquake. The straps must be disengaged and the gas line and water line shut off before the tank can be removed. The job is fairly simple and is easily accomplished with the proper tools. —San Francisco Gate
Next, you drained the water heater and removed the access panel, then, unfastened the old heating element. You put in the replacement coil, replaced the access panel, unhooked the garden hose, and turned the power or gas back on. After a few hours, you turned on the kitchen faucet only to be disappointed — no hot water. You have to face the sad fact the water heater just doesn’t work any longer. Now, you’ve got to junk the water heater and install a replacement. Here’s how to remove a water heater:
- Disconnect the power. Go to the main electrical panel and shut off the breaker to the water heater, if it’s electric. Then, you can disconnect the electrical wiring. If it’s gas, shut off the supply valve and give it several minutes before you disconnect the gas line. In addition, shut off the water supply and delivery lines.
- Drain the reservoir tank . Though you’ve done this before just a few hours ago, you’ll have to do it all over again. Hook a garden hose to the drain valve and allow the water tank to drain completely so you can move it.
- Disconnect the water lines. Once the water heater is drained, you’ll be able to disconnect the water lines by either unscrewing them or severing them. Be careful with severing the water lines because you’ll need to reuse these or you’ll have to patch or replace them.
- Carefully remove the water heater. You can now carefully remove the water heater. Have a friend or family member help you out, because the appliance will be heavy and awkward to move out-of-place.
