Hi - I'm considering replacing my 10 yo Whisperflo with an Intelliflo, but wanted to know if the inlet / outlet ports line up EXACTLY - there are 2" unions on each side of the whisperflo (top / back ports), but the height dimensions of the whisperflo and intelliflo look like they are about 1/4" off from the engineering drawings, (and the intelliflo doesn't have any of the port dimesions in their engineering diagrams - only the overall size of the unit.)
They look the same from the pictures, but would rather hear from somone who has done the swap.
