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.

Scott- the water pipes from one tank to the other are run in a cut in the
plywood in the aisle. perhaps someone has crimped that line if they replaced any
of the flooring? Ernie-83PT40 in Texas

That would make sense, except it's the line that doesn't run under
the floor that has the problem. It's the street side line.

Thanks

Hi Scott,
Don't have two tanks so can't share your situation.
Some things I might try:
1.) Run water into the bottom of the "T" so it will
go in equal directions.
2.)Restrict the curbside with a smaller hose, fitting,
or check valve.
3.)If possible pipe the overflow from street side to
curbside allowing street side to fill first.
4.)Restrict the air escaping from curbside, it
cannot fill fast if the air is not displaced to
outside the tank.

If you can solve the problem without adding a valve
that you have to turn on and off at each fill-up you
will not only make it eaiser on yourself but eliminate
the opportunity to forget.

Scott,

My 'Bird is identical to yours and I just now finished filling the
water tanks. I stopped filling as soon as there was water flowing
just a little bit out of the curb side overflow, I went in and
checked the street side water tank level, by accessing it through the
small compartment door at the bathroom door end of the street side
bed and by placing a flashlight up against the tank I can see what
the water level is and it is 2 1/2" from the top, I'm guessing that
would be about 90% full.

I always stop filling at this point, so I have no idea how much
longer I would have to leave thee water running out the curbside
overflow to finish filling that last 10%. I might try raising the
right side levelers next time to elevate the curbside tank and
overflow and see if that helps, maybe you can try just the opposite
on yours.

Scott:
I have a side bath as well, but my two suggestions:
- What happens when you turn the water on with less pressure?
- Why not plug the curb side overflow and let it fill the other tank till it
overflows.

Scott
Our 1980 rear bath has 2 fill lines and no sporlan valve as far as I
can tell,there is a ball valve on each fill line. It does draw water
similar to the way yours fills because of the T to the pump. I did
cut a hole in the top of each tank to add water on the road without a
hose, used 8 inch round screw in deck lids. It allows us to clean the
inside of the tanks, also helps to blow out the lines before winter.
I just wish there was a way to keep from losing so much water out the
overflows each time you hit the brakes, every time I stop I leave a
good trail of water out of each tank, I bet thats not what the people
behind me think it is? Sorry to get alittle of topic as usual.

Scott has a good answer to his question, in the question, replace
the T with a Y. I myself would just drink coffee and watch TV until
both tanks overflow.

Irrigation suppliers sell pressure compensating flow valves for drip
irrigation. I've used them inline on drip systems that run down hill
over 200 feet (major PSI variables) with little problem.

http://www.hendricksonbros.com/flwcntrl.htm

the problem with using a ball valve restrictor on one tank is volumn
change expodentialy with increased pressure at given line size. and
using a pressure regulator on the fill to maintain the proper
pressure for the adjusted restriction will only protect the top side
of the math. (just wait for both tanks to blow water)
