Subject: PVC grey water tanks...was: Auxiliary fuel tanks for Syncros and
2WDs
When camping, I don't like the hassle of attaching a hose and 5-gallon
bladder to our sink drain (although this is what I do). We often camp in
places where, the following night, some Quidam and his brood might pitch a
tent. So, I'm not keen on letting my scrambled eggs and coffee grinds drain
onto the ground.
I have the idea of a 20 gallon (75-80 liter) gray water tank, and before I
go to the engineering firm of Spanky & Alfalfa I thought I'd check with
y'all.
Here is what I am thinking. I am seeking a box-shaped, translucent
polyethylene (like our water tank) under-floor tank that fills the entire
length and breadth of the space between the outside passenger door and the
passenger main frame rail (about 125cm x 25cm). It would hang on U-shaped
metal straps, using the four floor mounted bolts for the propane tank (in
place for RHD vans).
I imagine it hanging down about 3" below the edge of the van, about as much
as the propane tank. The bottom would have a slight incline to the floor,
that is, it would be about 22cm thick at the front, and about 27cm thick at
the rear. Those dimensions would bring it to about 78 liters, providing for
capture of the entire capacity of the fresh water tank, with a large margin
for slosh. The incline would provide for complete drainage, and would
encourage solids to settle near the drain valve.
At the bottom rear of the tank, there would be a 5cm Thetford waste valve.
At the top-front of the tank there would be a 3/4" inlet hole for wastes
from the sink, and a 1/4 nipple to attach a vent line.
Granted, I could make/have this made, but I am hoping someone has seen
something like this...thoughts?

Not at present. I ordered Daerr's
catalog to find some more details.

Another idea is to use separate
filler necks, like it is usual for
the water tanks which are on same
place and of same design. To get the
fuel into the main tank you only
need to have a regular fuel hose
which is connected to the return
line of the original installation.

I don't know about these, but there
are water tanks made of PVC which will
resist Diesel. But they are not certified
to carry fuel at all.
