I just saw this thread and I purchased the same Flo-jet 4406-143, because it was 1/3 the price of the Shurflo that stopped working.
I could not get it to work with my accumulator and then I read in the installations instructions not to use an accumulator, I just uninstalled it and got an Aqua Jet by Johnson Pump.
Now, when I first installed it, it also cycled on and off immediately, though the taps were open.
I took out the water filter element and that cured the problem. The Flo-Jet may have worked then, but it seemed adamant about not using an accumulator, which I do not want to eliminate for the reasons mentioned above.
