One of the most common household plumbing projects is replacing a water heater. Many
potential dangers can result from improper water heater installation.
Removing your old Toilet:
The most common overhead-plumbed water heater hookup .Before you can connect the new
heater, the old one must be removed. First, turn off the gas or electricity to the heater. Open a
hot water faucet to allow air into the system. On a gas heater, separate the vent pipe from the
draft hood. The hood should lift off after you remove the sheet metal screw that holds it. After
checking that the pilot light is out, disconnect the gas line at the heater and cap it. Next, remove
the heater from its water piping. If the pipes are connected with unions–removable threaded
fittings–take them apart with a pair of pipe wrenches. The old heater can now be removed and
disposed of in an approved manner.
