yes, if the valve allows any air leakage, or entry, the pump will come on and off. Ours did this, and Thor replaced the valve, which corrected the problem.....
now I have a new problem that recently came to light.
I noticed several days ago that when I have city water, and move the valve handle to 'city water', it continues filling my tank, as well. I found that if I turn the valve to 'winterize', the city water works fine, with no water to the tank.
I assume the valve needs to be replaced again, but the question is this:
If the 'city water' and 'winterize' both work for incoming city water, what is the need for both?
