Hello.

Mine is a 1977 23ft transmode made by coachworks as far as I recall. Rear bathroom. 2 loft beds on the passenger side in the rear, fresh water tank below the bed on the passenger side.

Here is my question:

If the Rv is connected with a hose (on the driver side) to city water, and the fresh water tank (below the bed) is full. If I turn on the faucet in the kitchen or bathroom sinks (to get some water to drink) ...am I getting water out of the hose/city water connection (which is constantly on) or am I getting water out of the fresh water tank??

And is there a way to chose (other than shutting off water from the city water hose) ?

I think I know the answer but wanted to get an expert answer please.

Thank you.

Well, I know how my coach works relative to this. When my tank is full and I'm hooked to shore water, if my pump is off, water comes from shore. When hooked up to shore water, the pump should not be on. Pump is for water from the tank when not hooked to shore water. JMHO

Fair enough - just trying to help, since it didn't appear that anybody else was trying to...

In any case - fluid physics aside, my point was that the only way to switch between the two sources would be to manually turn the shore water off...

I suspect that my reply helped more than silence...

Thank you Rob and everyone else.

What I am trying to do is to live in the RV in a place that has Well water which is not fit to drink (I was told it has too much Iron). So I am trying to figure out how to resolve this issue without buying bottled water (I don't like to drink water that has been sitting in plastic bottles for who knows how long).

Thus I asked: If I were to fill the fresh water tank with drinking water and connect the city water hose to the constant water supply for showering and washing. If there is a way to switch easily between the 2 water sources.?? So I can get drinking water as needed without a lot of trouble.

I am new to this GMC RV and living in an RV so I am trying to figure things out.

And would a faucet mounted filter (the type with a cartridge) filters out the Well water to make it drinkable.?

Thanks.

During my 57 years of RVing, including travels in the GMC from Key West,
FL, to Fairbanks, AK, I've used water from every campground we've stayed
in, usually filling the on-board tank from those same sources. I use that
water for washing, coffee making, cooking, bathing, and any other use
necessary.

I periodically sterilize the fresh water tank and the entire plumbing
system with hydrogen peroxide, but I'm not religious about it. I've seldom
noticed a strange taste to the water; when I have, it was due to the water
source, to which locals had become acclimated, but it was merely a taste
problem.

SHE won't drink from the coach, campground, or our home water system,
preferring the absurdity of bottled water (wherever that happens to come
from).

Neither of us has EVER had any illness, nausea or other symptom of
waterborne disease from this camping practice.

Personally, I think there's too much paranoia about water (in the USA) --
just like too much "Political Correctness" in other facets of our lives.

Now if we want to talk about other parts of the world I've visited, my
position is subject to change.
