Gray water only sewer hose recommendation--320S

Oyaji

Anybody have a recommendation for a gray water only sewer hose (with necessary connections) for a 320S?  (It has a cassette toilet)

I'm almost embarrassed to be asking such a trivial question, but there are so many options for sewer hoses in the market place, and at different price points , I'm stumped.  And my trailer didn't come with the apparently standard freebie hose.  

I only want to buy this thing once!  Thanks.

I use two of these (one for extended reach if necessary). No issues to date. If you're in climates that have extremes keep that in mind as high solar exposure and/or cold tempuratures can shorten the lifespan. Fortunately if it does leak, it's only grey water. No good, but so much better than the alternative!

@Oyaji, we use the rhino hose. Ours is for black and gray. We've had 4 people in a 320 S for 2 months at a time and emptying the tanks was a priority. We've used the rhino hose at 0°F and at 125°F and every temp in between. No leaks, no failures, no problems. I highly recommend it. Btw, it is the first and only gray/black hose we have ever had, as our dealer gave us absolutely nothing as part of our trailer purchase.

I would use the Sewer Solution as it is a much smaller diameter hose. As You will only be dumping your gray water tank. I have used it for both black and gray water with great success.  Look up Sewer Solution. Art

Don’t feel bad!!  I was sitting here wondering the exact same thing as we are picking up our 320 next week!  Thanks for asking the question!!!

I would get on of these and a 10’ or 15’ of 3/4” garden hose. It won’t drain as fast as a 3”. Probably less than 5 minutes. Once in a while you could fill the tank with fresh water and drain it in your yard to get a good flushing action.

+1 for the Rhino-Flex, but be sure you check that the ends are screwed into the hose securely when you use it. I believe it was @Michigan_Mike that was lucky enough to experience the disincorporation if his Rhino while in use... Couldn't have been pretty!

The Sewer Solution I found to use a whole lot of water for its ability to 'macerate', took a lot of time (for solids), and then I was left with more parts to clean. I finally got rid of it.

The smaller diameter hose is easier to stow and clean. Just a little more time at the dump-site. You can timee your dumping at the dump station so there is no-one waiting in line behind you (easy with off-season camping). 

If you're just doing gray water, with no solids, and you want a small diameter hose, I'd go with the waste cap that @Dalehelman referred to.

@Oyaji - be aware that the small, Valterra cap outlet makes for a very slow emptying of your gray water.  That is fine if you are dumping into a portable tank at your campsite, but you may have a long line behind you at a dump station.  We have the Valterra cap used at a campsite and a Rhino Flex used at a dump station.

Wow, I'm liking that Valterra cap idea, at least to start.  As we all know, there isn't a whole lot of storage space on or in a 320S!
