Water heater with sediment agitating inlet bushing

A water heater comprising:

• a water tank, the tank having a cylindrical wall, an upper dome, a lower dome, and defining an interior tank volume between said cylindrical wall, upper dome, and lower dome;
• a cold water inlet positioned near the lower dome;
• wherein the cold water inlet comprises an elongated body, having a first end which extends into the interior tank volume, and a second end which remains outside the water tank and is affixed to the tank, portions of the inlet body defining a blind bore which extends inwardly from the second end towards the first end along a first axis, wherein the first axis is perpendicular to a line tangent to the cylindrical tank wall at the point of intersection between the cylindrical wall and the first axis;
• portions of the body defining an opening extending between the blind bore and the interior tank volume, the opening extending perpendicular to the first axis to define a second axis, the second axis being parallel to the line tangent to the cylindrical tank wall;
• an index mark on the second end, which remains outside the water tank, the index mark aligned with the second axis, so that the position of the opening can be visually aligned tangent to the tank cylindrical wall.

A water heater comprising:

• a water tank, the tank having a cylindrical wall, an upper dome, a lower dome, and defining an interior tank volume between the cylindrical wall, the upper dome and the lower dome;
• a cold water inlet positioned near the lower dome;
• wherein the cold water inlet comprises an elongated body, having a first end which extends perpendicular to the cylindrical wall a short distance into the tank volume, and a second end which remains outside the water tank, and is affixed to the exterior of the cylindrical wall, portions of the inlet body defining a blind bore which extends inwardly from the first end towards the second end along a first axis, wherein the first axis is perpendicular to a line tangent to the cylindrical tank wall at the point of intersection between the cylindrical wall and the first axis;
• portions of the body forming an opening extending between the blind bore and the interior tank volume, the opening extending perpendicular to the first axis to define a second axis, the second axis being tangent to a circle defined by the cylindrical tank wall;
• and
• a drain positioned at a location where the lower dome meets the tank wall, closely spaced from the cold water inlet at a side of the body opposite the opening extending between the blind bore and the interior tank volume.
