Dip Tube Inspection and Replacement
Step 1. Move the gas control power switch to the “OFF” position
Step 2. Unplug the water heater from the wall outlet.
Step 3. Turn off the cold water supply to the water heater. Connect a hose to the
drain valve of the water heater and route to an open drain. Open a nearby hot water
faucet to vent the water heater for draining. Open the drain valve of water heater and
allow the water heater to drain to a point below the inlet connection nipple.
Step 4.
Disconnect the inlet nipple from the plumbing system.
Step 5. With an appropriate tool, such as a pipe wrench, remove the inlet nipple/
diptube from the water heater. Use caution not to damage pipe threads.
Step 6.
Visually inspect the inlet nipple/diptube. The inlet nipple/diptube should
be free of cracks and any blockage. Hydro-jet slots should be open and free of any
blockage. Any damage, such as cracks, restriction due to deformation, or
unintentional holes are not field repairable and the inlet nipple/diptube must be
replaced.
Step 7.
Upon completion of the inspection or subsequent replacement, reinstall
the inlet nipple/diptube into the water heater. Connect the nipple to the plumbing
system, resume water supply to the water heater, and refill the water heater.
Step 8.
To resume operation, follow the instructions located on the water heater
lighting instruction label. Or, use the lighting instructions located in the water heater
installation and operating manual.
