I am updating the plumbing on my 1966 Caravel
, after discovering some leaks in the copper fittings caused by a freeze, and vibrations, etc. (It's old!)
I have at least a partial diagram of what is involved, and wanted to get started but could use some advice about possibly adding more modern safety features that this Airstream wasn't built with. (Are there things I should be adding, like back-flow valves of some sort?) This trailer has no "grey water" capability. Either it's clean or it drains straight to the tank with the toilet waste. I don't think there is room enough to do much about that, although I am open to suggestions about saving water.
What is currently configured seems to be functional insofar as working when hooked up to city water. That much I have tested. There is pressure to the faucets and toilet, and the hot water heater seems to heat up nicely without exploding. Most of the lines are half-inch copper, but some are smaller, and some are simply rubber hoses with hose clamps on them. Is that normal?
In addition, there is misc. plumbing works and a 12v
diaphragm pump in place to take advantage of the fresh water tank, but I have never used it before. I did flush out the tank as best I could a while back, and drained it via the valve installed for that purpose. I'd like to make it safe and fully functional for off the grid use. What I have not tested yet is the 12volt water system. (I need to fix the leaky copper joints first.)
Assuming I can get the power to the pump okay, and the leaking fittings re-fitted, are there any obvious modern safety features I would want to add while I am doing all this for 12v
or city water use?
Take a look at the following illustrations for a guide as to what I am working with.

In the side port, near the city water hookup there is a small pressure release valve in line beyond the larger, more complex intake pressure limiter. I am assuming the pressure release valve that drains to the street is there as a safety feature to take care of the hot water as it expands - or also to let off excess pressure if the larger water pressure intake limiter fails somehow?
thanks in advance, and look for more info as I sort this all out. It's a work in progress!
