I have a new-2-me 2007 Feather Sport 165. Everything that I've been able to
figure out works excellently, air, heat, hot water, electricals both 12v an
Unfortunately I've got some very low level non-understanding of how this
water system works. I've got very little experience with plumbing but can do
repairs. For instance the city feed port was loose inside the wall fitting
and leaking a geyser so I figured out how to uncaulk it, *tape* it properly
and put it back together snugly. (I've got a ton of background in
electronics so I can follow pipes and valves and generally figure out where
they go and what they do.)
Believe it or not I'm not understanding if/how the main water tank even fills!!
I *should* be hearing water going in, but I'm not even 100% sure if it's
empty after a system drain.
I see the city water come in and split. One side goes forward and splits
again immediately to the sink cold water and to the drain valve.
It splits again with one line going back probably to the bathroom and
heater and the other side towards the pump.
On the other side of the pump is the tank and the sanitise-fill-hose.
I see the three drain valves for hot and cold water, and one directly from
OK here's where my non-understanding starts.
I can't even tell if there's water in the tank or going into the tank. I
connect to city water and I hear the hose pressurise but hear no further
flow, and if the tank is empty I -should- be hearing flow and splash because
it should take a few minutes to fill a 30gal tank.
So that implies the tank is full.
But if I open the tank drain valve nothing happens nothing drains out.
The drain valves for the hot/cold pipes -do- drain when I open the faucets
so I know I've got something working right.
If I turn off pressure at the city port the faucets work till the pressure
drops, and the pump will kick in, and it keeps flowing implying that the
tank is -not- empty. But I can't mess with this experimenting too long
because I know the grey tank will eventually fill.
I half think there might be some pressure switch that enables/disables flow
under certain conditions but I'm not seeing any odd objects in the lines.
I'm also not understanding the pressurisation aspects of the system.
The water must go through the pump to get to the tank. I can see that
physically. But I also know that the pump pressurises the tank, and that the
tank pressure then delivers the water. That says that the water is passing
through the pump in -both- directions. But that's not making sense to me
because if the pressure is low and the pump is on to pressurise the tank I
don't get it how the tank pressure is also delivering the water at the same
I wish this thing had tank gauges, intend to look into adding that later.
For instance I'm going on a 3-day drive and I would want only about 10gal in
the tank and then fill it after I arrive.
BTW I will be participating more but I need to get this thing ready to travel
next week. (I have all the tools to work on anything on the road too.) For
instance I took pics of a mod to patch the radio/CD AUX input out to
Thanks much. Have a
