    Another arithmetic question

    OD is 30.73 and ID is 15. Using area exposed to pressure is 3.14*30.73^2/4 minus 3.14*15^2/4 results in 565 square inches. At 80psi that's 45,000 lbs trying to blow out sidewalls. There's also the tread area to consider. The tread width is 9.25 inches. Tread area is 3.14*30.73*9.25 = 892...

    Electric Motor Capacitor Failure

    RCP, Did you use the 680mfd capacitor wore out recommended? If you picked a lower rating, the motor would spin slowly and eventually capacitor would fail or breaker/overload would trip. Since you haven't smelled anything with motor, you still have hope. One item no one has mentioned is the...

    Sort of an electrical question. somewhat long.

    Almost certainly not. A dimmer effectively reduces the voltage to the motor. You probably have an induction motor. If you reduce voltage enough to affect the speed by any significant amount, the motor is less efficient and begins overheating. There are certain exceptions to this but quite...

    Run capacitor?

    The old motor without the brown leads is a shaded pole motor. It does not use a capacitor. Instead of capacitor, it uses shading rings to create the phase shift. Untitled URL Link

    Sump pumps

    The Flotec is a good pump assembled in Wisconsin. Many of the components are manufactured in Wisconsin too. The PSC motor it uses is a better selection for a sump pump than the split phase some others use. (Split phase has high inrush current and inherent reduced reliability due to the...

    60hz

    Don't waste money buying any equipment. With a simple clock with second hand and AC lighting you can tell speed of engine very precisely. Remember AC lighting is flickering at 120Hz or 7200 flickers per minute. (120 Hz because 60Hz sine wave has both a top and bottom half.) Just put a mark on...

    Pittless connector / well help !

    That type of pitless adapter wedges the piece on the pin against the casing. You need to remove the T-Pipe and loosen the bolt underneath it. That bolt pushes that wedge against casing.
