1. In combination with a water tank of a water heater system, an improved fitting comprising:
- a T-shaped fitting having a bifurcated passage comprised of first and second channels, a fluid inlet, a fluid outlet connected to said inlet, said first channel being connected with said inlet and said second channel being connected with said outlet, said passage including a fluid flow diverting vane extending along said passage to define said channels, said vane extending into said inlet to divert a portion of fluid flowing into said inlet through said first channel into said tank, the remainder of fluid flowing into said inlet flowing directly to said outlet and commingling with fluid flowing from said second channel to said outlet, and temperature sensitive control means in said channels to measure water temperature in said first channel, and to also measure water temperature in said tank.

Abstract
An improved tee shaped fitting for the heating system of a swimming pool. The fitting includes a water inlet and outlet aligned on a common axis and a bifurcated passage joined perpendicular to the axis of the inlet and outlet. The bifurcated passage includes first and second channels defined by a vane, the first channel being connected to the inlet, the second channel being connected with the outlet. The vane extends into the inlet and diverts only a portion of fluid through the first channel to a water heater. The second channel directs water to the outlet where it commingles with the fluid which flows past the diverting vane.

2. The improved fitting of claim 1 wherein said temperature sensitive means includes a device extending from said second channel into said tank to sense the temperature of fluid flowing into said second channel for admixing with fluid from said inlet.
-
3. The improved fitting of claim 1 wherein said vane extends into said tank to prevent short circuiting of fluid from said first channel into said second channel.
-
4. The improved fitting of claim 1 wherein said vane has planar sides, is arcuately shaped and extends from a point on a line parallel to said flow of fluid into said inlet, to a position substantially parallel to the centerline of said bifurcated passage, said arcuate vane having a radius of curvature from 1/8 inch to 1 inch and wherein the thickness of said vane is no more than 1/12 the diameter of the inlet opening.
-
5. The improved fitting of claim 1 wherein the leading edge of said vane extending into the inlet is rounded.
