The built-in storage tube on the Rialta allows for nothing more than about a
6-10 foot long sewer hose and that's only if you can fully compact all of the coils
to squeeze the entire thing into the tube.
Several modifications have been proposed starting first with just an additional
storage tube and ending with the mod to the existing storage tube that will allow
up to 27' of sewer hose to be stored!
I have found that at some campgrounds, the location of the sewer
connection is not compatible with the 10-foot sewer hose that comes with the Rialta.
A 20 foot hose will not fit into the built in storage tube. To get around this
problem, I made up a 26" long tube of 4" DWV (drain-waste-vent) pipe with a cap
in place on one end and a connector on the other that accepts a screw in plug.
It easily holds a 20' sewer hose. I mounted it longitudinally under the right
rear corner of the coach along side of the trailer hitch angle. I used stainless
steel worm-drive clamps to hold it in place. I have posted two pictures in the
photos section of this list.
I originally made up a 5' long tube last year and mounted it
transversely below the trailer hitch. It was a bit of overkill for the length
of hose but I needed it that long in order to get mounting points at each end
of the trailer hitch. Well, this was a bad idea as it hung down too low and would
bottom out on such places as steep driveway entrance ramps to gas stations or
at similar type spots. I re-worked the tube this spring and came up with the current
design, which works fine.

Subject: [Rialta-Tech] Harry Pinchot's Sewer Hose Modification
Back in June of 2003, Harry Pinchot posted a message (#8268)
about his sewer hose modification that increased the length of hose that can be
stored by cutting and then lengthening the tube through the generator compartment
and then routing it up and forward under the back dinette seat.
I had just gotten through my first adventure with dumping the
black and gray and all other colors of interesting stuff on my legs and feet because
of a too-short hose, so the idea had my attention.
I went out and bought all the right stuff, printed out the pictures
and instructions, got additional input and guidance, and fearfully started in
to make it work....last August. I couldn't make it work. I believe I have cut
my full length piece of white 4" PVC more than anyone else trying to get it right...
and I won't be sharing the leftover piece to help someone else... there isn't
Now before Baldy tells me I'm too stupid to own a Rialta and
I should sell... quick before I do any more damage to it... *grin* I would like
to report that today I finished the job. There was a reason it wouldn't work for
me, and I figure it's important enough to mention.
I went to Home Depot to get my 'parts' and after keen observation,
I realized that Harry's 90 degree connector looked a lot different from my 90
degree elbow. His shows a long, graceful sweep. Mine made the turn in half the
space. Looking more closely, I noted that my end cap was flat on top, while his
looks curved. Sure enough, I think that Harry's solution came through Lowes and
their pipe brand is different... and that made a HUGE difference, buying the 45
and 90 degree elbows at Lowes yesterday made it possible to make the turn at the
top rear of the bench that I had been unable to accomplish before.
So the moral of the story, if you want to make the mod that
will let you store 27' of sewer hose instead of the original, get your parts at
Lowes to make it a lot easier on yourself.
99QD with an awesome sewer hose!
What you did was describe the difference between a regular 90
degree "el" and a "long sweep el." The former is used on the venting side of sewer
systems because sewer gas doesn't really mind the sharp turn, while the long sweep
el is used on the fluid side because fluids DO mind. I think HD does have the
long sweep els too, if you know exactly what you want and where it might be. But
you're right, Lowes usually has a broader selection of plumbing fittings.
