Sewer hose replacement problem

[stlsailor]

I went to empty the gray tank yesterday on my 2017 travel trailer and there were a couple of pinholes spurting water so I quickly shut it off. I bought another hose (Camco, I think) but when I went to put it on late yesterday it was too small in diameter to fit over the couplings to attach to them. I thought sewer hoses were standard. I did notice as I was trying to replace it that the coupling was stamped Valterra. Does each manufacturer have it's own sizes? That seems absurd. What do I need to know to get a replacement hose that fits? I've had RVs for years, but never had to replace a sewer hose before.

They should be standard. I've had many hoses over the years and never found one that was a different size.

That's what I would have thought. But while I've taken the existing hose on and off the fittings several times, this one was simply too small for the fittings to fit over.

Can you show pictures of the fittings?

Should have a standard T1024 3" straight hose adapter .

The first one connected to the clear elbow is the one I tried. The part of the fitting that the hose fits over is simply too large for the size of hose. When that didn't work, I didn't try the other one.


EDIT: I just measured and the inside diameter of the new hose is 3-5/8". It is tryig to fit over an end that is 3-3/4" and it just won't give that much.

Not sure what's going on...
Can you place the 2 parts that don't fit close together and take a photo of that??

The first image shows the fitting that the hose must fit around. The second image shows that while the house should slide over the fitting, the hose is inside diameter 3-5/8" and it won't slide over the 3-3/4" fitting. I tried to use a screwdriver to pop it over but it simply pops out the other side. Just a big too snug.


I wonder about just getting something like a rhinoflex including fittings, but I've read different reports as to whether it will store inside the bumper.

I think your problem is Camco has a different thread/twist to the wires in the hose. 1 brand is left handed and the other is right handed. Had the same problems but I don't remember the name brand of the other hose but Camco was opposed from my original hose.

Good luck -- been there

Thanks. I can't imagine how I got this foolish idea that a sewer hose was a sewer hose was a sewer hose. That would have violated the rule that any project, no matter how simple, requires three trips to the store. I didn't notice that the black fitting had Valterra stamped on it until I went to replace the hose. I suppose I need a Valterra hose. Who would have thought?


Before I head back to the store soon I'm trying to decide whether to try another hosed (Valterra this time) or go with a a whole new system. Replacing hoses is simple when they fit. Finding the time to go back and forth to the store on a trip that is a working trip is a different matter.

I've had good experiences with the Prest-o Fit blue line system. Still on the original hose @ 7 years . Have replaced the connector a couple times. Would recommend it. JMO

I've had to cut the vinyl flap back to the wire to get some hoses to go over the fittings. If that flap folds under (doubles) it will never slip on the fitting. A little silicone spray or plumbers grease helps too.

BTW... Rhino hoses and fittings fit fine in a 4" bumper. You simply index the fitting tabs to fit into the corners of the bumper. I've got a 15' section and two 5' sections in mine as we speak.

Thanks. Will keep that in mind. Will be limited to what I can find in stock here, so will have to see.

In this case the flap wasn't folding under, though your point is well taken as I did notice that happening one time in the past. I never thought of silicon spray.

I see what's happening now. I had the same problem when I bought a new hose. I didn't think it would fit either. It eventually did.

It'll take some struggling, some patience, and maybe a bit of swearing but it'll go. It'll be tight though. Which is probably a good thing considering what goes through the hose.

You might try a heat gun on the hose to get it to stretch over your fittings. That said, I to converted to the Blueline slip on hoses and fittings a few years ago. Good luck.

simple fix get a hair dryer or hot gun heat up hose it will slip on done it many times

This sounds like a good idea. I don't think we brought a hair dryer this trip, and we were already back at the store when I got the last 3 messages. So I went ahead and exchanged it for a Valterra hose and when I got back, voila, it fit perfectly with no problem. Well only a tiny problem if you call it that. It was designed for the rotating clamp with the yellow handle but the store was out. So I used the one from my existing setup along with the ordinary screw type clamp and it all worked fine.


Now, IWriteCode, I expect you're right -- a lot more patience with a bit of swearing thrown in might have done the trick. But much easier with one that fit.


And, Shadows4, I hadn't heard of Blueline before, so I may check them out for the future. How do they work differently? What's their advantage?


So, job now done while there's still sunshine and weather that's a mite warmer!

[jeff64]

If all else fails, a pan of hot water with a little dish detergent for 5 minutes should do it

X2 - It is tight, but will do the trick.
