Typical causes of water temp problems on pilot water heaters
INSUFFICIENT WATER TEMPERATURE
Temperature selector out of place--------------Re-set to desired position
Valves improperly positioned---------Check that bypass valve is closed
Improper air adjustment------------------------Adjust main burner air shutter approximately 1/4 way open
Partial main burner blockage------------------Remove blockage (run bottle brush thru tube...clean ofifice with alcohol)
Improper main burner adjustment------------Re-align main burner and main burner orifice holder (should be 'straight' shot thru tube)
Flame spreader mis-aligned--------------------Re-align or replace main burner (should be parallel to end of tube)
Blocked “U” tube--------------------------------Remove blockage (run bottle brush thru combustion/exhaust chamber)
Also check any hand held shower wands.......turned off at hot/cold knobs and not just on handle.
