Sewage Drain Hose

[Reddemab]

He flexible hose that came with our rig doesn't seem to be the best option. Dont the ribs catch debris? Is there a smoother option? Rinse the hose every time I assume?

Make sure there is plenty of liquid in black tank, dump it first, then flush with the grey tank. If you are hooked up to a sewer in a campground, most people leave grey tank open to continuously drain. When black tank is at 3/4ths, close grey tank to build up fluid to 'flush' black tank when you dump it.

Great suggestion, thanks!

Yes they catch stuff, BUT. There is hose that is smooth but it does not accordion/collapse so you have 10 or 20 feet of 3" stiff hose. Clean and you have two options seal it up air tight caps or let it air out. I opted for the later.

The hose maybe cheap they have heavier gage plastic hoses that will stand up better with use also hose slinkeys to keep off the ground surface.

There are several improved versions of 3" corrugated sewer hose (also called a stinky slinky) for RVs. IMO, the better ones are thicker, heavier gauge material that is less prone to leaks, but all of these have ribs and corrugations that are hard to keep clean.

There are also 2 alternatives to the standard 3" corrugated RV sewer hose that I am aware of. One is the macerator pump like the Sani-Con. A macerator needs 12V power to operate.

The second alternative to the standard RV sewer hose is the Sewer Solution. The Sewer Solution needs a source of water to operate. I have been using a Sewer Solution since they first came out around 2000, and it works great and is less expensive than a macerator.

The macerator pump and the Sewer Solution are slower to empty your holding tanks than the stinky slinky. I use my Sewer Solution when we have a sewer hookup at our camp site, but I use my stinky slinky at the dump station because it is faster, and I don't have to worry about having a water source for the Sewer Solution to operate.
