For years we used conventional sewer hoses, and we had all kinds of storage tubes for
them. Under the rig, on the back bumper, and while they worked, we needed so much stuff to make it work. Some campgrounds have sewer connections that are 6" or 8" above the ground. Now most campgrounds in California INSIST that your hoses are supported in a
"slinky" or some other device to keep them off the ground. Failure to comply will result in a ticket.
So last year I invested a $120 in the Sewer Solution, check out their website at;
www.sewersolution.com
Unit comes with two, 10 foot discharge hoses, and I bought a 3rd length. The unit will also discharge into 1" pvc rigid pipe, and I carry two, 5 foot lengths of this in the basement
with 1" couplers to join it together. In total I can discharge up to 40 feet.
The Sewer Solution uses the simple venturi principle. The unit requires a separate fresh
water hose with a back flow preventer. When the water pressure to the venturi is activated
it literally pulverizes all the contents of your black tank. For normal operation while in
a park, we leave the grey tank valves open, and the drains simply flow in the sewer drain.
The great thing about the Sewer Solution is that it will discharge up to a distance of 100
feet and 3 feet in height.
My entire Sewer Solution kit with the hoses fits into a sealed Walmart tub about 16" by 18
by 18". I always flush with fresh water when finished and there is no smell in your basement, no stinky hoses on your back bumper, etc. No moving parts, no macerator to wear out or hard wire, just a very simple and easy to operate device.
The unit discharges into a thick wall plastic hose with a 3/4" bore, no slinky or other
support needed, and you could drive over this hose and not hurt it.
