I've never wanted to find out. They are so cheap I just replace mine every 3 years or so. Mine is only hooked up when actually dumping. Just observing hose failures.. it "seems" leaks tend to occur most often after expanding the hose. I say that simply because I've seen a number of folks at dump stations go frantic with hose failures and can't imagine they would have hooked up a leaky hose if they already knew it was faulty. KWIM?

I'm quite sure mine would last much longer.. I've just never wanted to find out I used it one too many times.

I've used the Rhino hoses exclusively for 10 or 12 years. The longest I've got out of one is probably 1 1/2 years. I've had a couple of them which didn't last a year.

I think there are two factors which dramatically affect their lifespan. The first is environment. If you're parked in an area where the atmosphere is acidic, the hose deteriorates faster. I found this to be common along the coast of Texas where there are many refineries and other petrochemical industries, lot's of acid rain. The worst atmosphere I've been in was in New Mexico during some of the large fires a few years ago. One of my Rhino hoses lasted about six months, but it had ash on it almost constantly. Isn't ash what lye is made from? IMO, rinsing off the hose periodically may help when in these types of environment.

The other factor would be what you put down your drain. I know when I've used clorox in the toilet, my hose didn't last as long. I've also used caustic materials in cleaning the shower, this also affected hose durability.

We are always close to refiners. That is where my work is. Maybe that why I have such short life out of them

I'm revisiting this thread to answer my own question.  My Rhinoflex lasted just a week shy of 4 years of constant use.  A couple of days ago I noticed a couple of pin holes.  I have a new one on board, so it was time to swap hoses.

I guess I'm the oddball our RhinoFlex failed in less than a year and I didn't really like how it hooked up at the ground sewer connection.

We bought a Valterra Dominator kit and have been very pleased with it.

When the Dominator quits we might go with the WasterMaster.

IMO it  depends on were you are. In Florida for 6  months and exposed to the direct sun ours last about three seasons before

they dry out./

It also depends on your grounds crew. Weed whips and sewer hoses do not get along well. That's why we never left ours connected when not actively dumping.

We're fortunate enough to have large tanks, so filling and dumping is done as needed. The proper hoses are brought out, hooked up, used, and put away. I have two Rhinoflex hoses in case I need more hose to get to the sewer connection, but usually use only one. When they are hooked together I often forget which one was which, so I'm sure that both hoses have been used more or less equally.

Hmm , I've heard of those high dollar hoses . 

We have used the el cheapo brown hose ( more than one when needed ) for 6 years . IIRC , we haven't replaced them yet . But , I can see the one usually used is starting to fade in color , which might indicate it could be losing pliability . No leaks , so far .   When it does start leaking , I'll replace it with the one not used as often and then I'll have to but another brown hose to replace the replacement .  

Those brown hoses replaced the seriously el cheapo black hoses that were in the rig when we bought it . That was just after the first year .

We probably get 5-6 years from our Rhino hose. I don't remember when we replaced it last. We use it once a week to dump and store it away the rest of the time. We use our tanks.

Maybe someone can answer a question that we have always had. Why do people need to hook up the elec, water and sewer each night? Unless it is dumping day, we just use electricity each night and even if we are dumping we put everything away after dumping. I am not talking about small trailers but MHs and big trailers that have plenty of tank capacity.

We like to just get up and go in the morning. Minimize the AM packing up, generally on the road by 8 AM.
