Water pump

[Pete Masterson]

As a normal practice, the water pump should be "off" when you're filling the water tank or when you're on city water. 

On my coach, when I switch to "tank fill" (which trips a Sporlan valve), then the water pump will run continuously -- but not be pumping anything. I suspect that isn't the best for the longevity of the pump.

If I turn on the pump while connected to shore water, then the water comes from the water tank and the shore water doesn't go anywhere. It doesn't seem to cause any problems -- and I've done this a few times when I wanted "better" water pressure. (Note: I have a variable speed Shurflo pump. It provides 65# pressure while the shore water is limited to 45#. From time to time, a "nice" shower with a little more water pressure is desired -- or some dishes are particularly dirty and a little more pressure from the faucet is appreciated.)

Your system may be plumbed differently than mine... (Always a possibility.)

   What you are saying is the sporlan valve only controls the water

going into the tank & when you turn it off you get water from the pump

or city hose.  I thought maybe that is why I had trouble with my pump

is because a sporlan valve should isolate the pump from the city

water.
