Question about General Electric GE SmartWater Household Water Filtration System - GNWH38F
This uint has a Robert Shaw Valve/Thermostat. On the top there is the Shut Off / pilot push to light switch. Next to that there is an adjusting screw that looks as if it was preset because it had a red sealer or paint over it. I can tell that this adjusting screw has been tampered with. The red sealer does not match up. What does this adjust and can it be readjusted?
That is the flow to the pilot lite and no it is not supposed to be readjusted, if anything you should get the numbers off the gas valve and replace it, or depending on the age of the water heater get a new one,

it is important to turn off
the gas supply to the water heater at the manual gas shut-off
valve. This valve is typically located beside the water heater.
Note the position of the shut-off valve in the open/on position
then proceed to turn it off.
2. On the lower front of the water heater locate the combination
gas control valve/thermostat. Depress and hold
the lock tab located under the gas control knob on the right.
Rotate the gas control knob on the combination gas control
valve/thermostat clockwise until "OFF" aligns with the mark on
the front of the gas valve. Once the gas supply has been shutoff,
remove outer door. 3. Using a 1/4" nut driver or socket loosen the two screws securing
the manifold door assembly until they are free. Do not
totally remove the screws and plastic retainer washers from
the manifold door. The screws and retainer washers will be
needed to reattach the manifold door. 4. In this step, the thermocouple, manifold tube, pilot tube and
igniter wire will be disconnected from the combination gas
control valve/thermostat. Using a 7/16" wrench
disconnect the thermocouple (left-hand thread) and pilot tube
(right-hand thread). Using a 3/4" wrench disconnect the manifold
tube (right-hand thread). Carefully pull the igniter wire from
the igniter button.
5. Grasp the manifold tube and push down slightly to free the
manifold tube, pilot tube, and thermocouple from the combination
gas control valve/thermostat. when installation is complete and gas is back on, You should be able to relight the pilot and the functionality of your gas hot water heater should be restored.
