Potable Water Tanks & Pump
 
(Left) The Ronco tanks
arrive by UPS with fittings spin welded in the locations
specified when I ordered them. (Right) The
right hand tank installed under the dinette
bench seat. These are stock tank configurations,
and the cutout was a handy place to install
under seat storage.
 
(Left) The two tanks are
interconnected with 1 1/2" PVC piping. You
can see the gravity fill fittings on the RH
tank. (Right) The LH tank. On top of
each tank is a 3/8" fitting and tubing to overboard
vents.
 
Close up of the fittings
on the forward end of the RH tank and continuing
around to the drain valve and vent fittings
that go down through the floor to daylight.
 
The LH tank outlet is
connected to the 12v Shurflo
Whisper King demand pump, connected to
a pressure accumulator, which is in turn
connected to the supply line that runs back to the
cold and hot water plumbing. Also at this
point is the pressure fill valve (red handle)
and the overboard water system drain valve
(yellow handle). By opening the fill
valve when connected to city water pressure,
you can fill the tanks in a mater of minutes. When
the water comes out the overboard vents,
you are done.
 
(Left) The See-Level capacitive
sending unit mounts on the outside of the tank.
(Right) Close-up of the pump and accumulator. The
accumulator stores pressure from when the pump
runs and then extends the time in between when
the pump has to run again. It is not uncommon to
be able to fill 5 cups of water without
the pump coming on.
 
(Left) The rebuilt electric
water heater "Hub" reborn as the water pump on-off
switch. The original was melted from a short circuit,
so I rechromed the plate, and installed a new indicator
lens and LED bulb, rocker switch and outlet (all
from ebay). (Right) The rechromed potable water
gravity fill port. The patch covers the location
where the old filler was, and demonstrates the
increased capacity of the new tanks. |
