Rear Bath Fresh Water Tanks

[Scott Forman]

Hello all,

Wanted to share something I discovered today and also ask for advice.

My 82 FC35RB has two fresh water tanks, one under each twin bed. I
assume all RB's are configured this way. The fresh water fill line
has a 'T' in it under the road side bed, allowing water to flow from
the sporlan valve to both tanks. Since it is a 'T' and not a 'Y',
though, the curb side tank fills faster as it water flows straight to
its fill hose while it must make a 90 degree turn to flow into the
road side bed. This means that on mine, when water starts to flow
out of the overflow under the coach from the curb side tank
(theoretically indicating a complete fill), the road side tank is FAR
from full, maybe ony 20%. This is complicated by the fact that the
tank level indicator probes are on the curb side tank, so they will
show full even if the other tank isn't. This leads me to a couple
questions:

1) Has anyone else noticed this problem? I am wondering if this is
just a bad design on BB's part, or if I have another problem like a
clogged hose.

2) If it is a bad design, my idea is to install a ball valve below
the 'T', so that I can stop flow to the curb side tank while the
other continues to fill. Opinions on this?

I had to let water flow freely out of the curb side overflow for some
time in order to get the other tank full. If you have a RB, you may
want to check how yours works, you may not be getting a full load of
water.
