Diptube Inspection & Replacement
Step 1. Position the on/off switch of the gas control valve to the “OFF” position and
unplug the water heater from the wall outlet.
Step 2. 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 the water
heater and allow the water heater to drain to a point below the inlet connection
nipple.
Step 3. Disconnect the inlet nipple from the plumbing system.
Step 4. With an appropriate tool such as a pipe wrench, remove the inlet nipple/diptube
from the water heater. Use caution not to damage the pipe threads.
Step 5. Visually inspect the inlet nipple/diptube. The inlet nipple/diptube should be free
of cracks and any blockage. The HydroJet 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 6. Upon completion of inspection or subsequent replacement, reinstall the inlet
nipple/diptube into the water heater. Apply Teflon tape or pipe dope to the
threads and connect the nipple to the plumbing system, resume the water
supply and refill with water.
Step 7. To resume water heater operation, plug the water heater back into the wall
outlet and follow the instructions located on the lighting instruction label or the
lighting instructions located in the Installation and Operation manual.
WARNING
Water heater components and stored water may be HOT when performing the following
