Don, I have never had a problem except a belt on my pump. I have not chased down the plumbing or the electrical to the sporlan valve.
Mine works this way. In the electrical hook up bay is a switch that says water fill/off. With the city water hooked up water will go to the fresh water tank with the switch in the fill position. In this position, the water pump will run but will not pump water. In this position, water only goes to the fresh water tank. Place the switch in the off position and the water pump will pump water from the fresh water tank to the facets. With the switch in the off position, I simply hook up shore water and use it. I have never tried it simultaneously as there has never been any reason to.
If yours is like mine, a water pump failure would not preclude the use of shore water. A faulty sporlan valve might.
Hope this helps.

Does any one know an answer to this question. I have a part ordered
for my Shur-Flo water pump & while waiting for it I took the pump out
& tied the in & out side of the water lines of the pump together & I
am on city water right now. After I fill my water tank I put the
switch in the position that you get water at the facet's if the pump
is turned on or it is on city water. Question? Does the water pump
being turned on open & close the sporlan valve or what control's the
valve?
