Filling fresh water tank on 2014 Vista

[Jht1954]

This is a rookie question because I’m a rookie. We have a 2014 Vista and i need to get this straight. I hook the hose up and turn the water the water on no problem. There’s a switch that says fill tank one way and normal the other way. My concern every time is not sure if the pump should be on or off. The uncertainty is because i blew the pipes inside once and blew the spicket another time. I know to always use a regulator which I do now but I’m not sure if the water pump should be on or off until tank is full. My wife is usually inside and keeps an eye out for pipes blowing. There’s a power switch outside as well as one inside and she can’t remember if she turned the pump on the white filling it when our bathroom spicket blew. So please help me out with this simple problem and then I’ll know for sure what to do. Thank y’all for your time. PS what’s the best water pressure for the water coming in for the 2014 Vista?? Thanks.

I thought 50-60psi tops. I would invest in one of these. You can adjust the pressure.

On mine as long as the valve is in the Fill position it doesn't matter whether the pump is on or not. I do need a 40-50 psi regulator and pump off in order to use the valve in Normal position.

If I leave my pump on while filling the tank, it runs. Because of this I turn it off.

You have two separate but joined systems on water. One is to use when hooked up to a water line. For that It is safer to have a pressure regulator as some systems near mountains may have extremely high pressure. Normally any reg set to less than 50 will be fine. I keep the cheap preset ones and don't worry what to set.
This is a handy one:

On city water, turn the valve to normal when just using the water on hose and fill when you want it to fill the tank. No help needed from the pump so leave it off but do remember to turn the knob back to normal after filling the tank or you will get very low flow at faucets.
The only time you need the pump on is after you have water in the tank, want to use some but are not hooked to city water. Turn the pump on and you likely will hear it pump until it gets pressure up on all the pipes and then stop. When using water the pump will cycle on and off to keep the pressure up and water flowing. We turn the pump off after we are done but it can be left on if you feel like it.
