Water

I was wondering / when hooked up to "city water" does the draw of water come directly from that source or is it drawn from your water tank first? What prevents this from filling your water tank? Why have a gravity fill?

I appreciate your help in understanding water systems.

1/ city water is charged to the city water system in your unit.
2/ you can fill the fresh water holding tand from the city water system.
3/ NO the city water does not fill the holding tank first then draw the water back into the unit.

hope this what you were looking for?

You should have a selector valve for filling your holding tank. If this is in the non tank fill position then you are running directly on the city water and not through your tank.

Water

You should have a valve to divert the water flow from your potable water hose to either go to your water tank (you will need to use your onboard water pump) or directly to your plumbing system (pressure supplied by the city or local water well).

It is possible to use both city water and tank water by simply turning on the 12V pump while you are using the city water. Some campers/MH fill the tank and use city water by connecting the hose and turning a valve to fill or to house if you are filling the tank in this fashion you would need to have the pump running to get water inside. Once you turn the valve to house you will be taking water only from the city water supply and the tank will not fill. On others there is a cup/gravity fill that you lay the end of the hose into to fill the tank. The hose would need to be removed and attached elsewhere to use the city water. and using the tank water requires turning on the 12V pump.

Normal plumbing diagram
Tank--Pump--T--Faucets and such

City water inlet has a check valve... Output side of check valve is connected to the "T" above.

There may or may not be a valve that lets you "Quick Fill" the storage tank..

On my friend's 2001 MH, he has to turn the bypass valve under the sink when he uses city. On my MH 1996 I don't.
