Interesting that you should ask this today; i was just examining the water
system i've pulled out of my Trailwind. It was added sometime later,
probably in the '50's, maybe as late as the '60's...
It consists of a Sears 'Home-Art Glass-Lined' tank... 25 gallons or so? not
sure...
and a small 12v dc air compressor which puts out up to 35psi of air
pressure, supplied to the tank through a length of 1/4" copper tubing. It
appears that the tank is filled with water through the same valved fitting
through which the water is supplied to the sinks, etc, which would suggest
that the tank be de-pressurized or the pump turned off while filling.
There is no 'water pump' per se... the small compressor pumps the tank up to
35psi, and when you open a tap, the water is 'pushed' from the tank to the
tap, as opposed to being 'drawn' or 'pulled' by a water pump 'downstream'
from the tank...
It appears that this compressor may have an automatic cut-off at 35psi, so
that it maintains the tank pressure. Don't know, haven't tried it out yet.
