Besides all that you are putting in positive flow the whole time. Only back flow you get is from the positive side of the Black valve. Just a question?
I read the comment as poster would be using the expandable hose to replace the black hose portion of the sewer solution so it would be carrying black water.

I bought a pair of 25' blue ones.
Kinda emergency purchase.
Going to toss ten in the bucket under the rv. You never know.
I like the size, and they work.

Tried that.....didn't work. Once I opened up the nozzle it didn't have much flow to it.

I have been using an expandable 50 ft hose for about 8 months now with no problems so far. Bought it as a backup hose and decided to see if it would last. Sure is easier to use than a standard garden hose, but don't know what max pressure it will handle or for how long.
Wish I could have found 25 footers.

The original blues ones are one that probably can withstand the higher pressures. Which is sought after. I don't think they make those ones anymore. But the green ones are garbage and poorly made.

Have used both the green ones which are good for about 2 or 3 months before springing a leak, have cut them off and repaired them. I now have the black one and have used it for 2 yrs with no leaks. It could blow the next time I use it and I'll just cut it off and repair it. Don't use it for anything but the black tank flush.

I had a green one with plastic fittings that I bought for black tank flush but used for other yhings. It worked well until it sprung a bunch of leaks one day. I can't say for sure but the leaks may have been caused by a certain German Shepherd's teeth. I will probably get a new one eventually.

I did not say that,......the sewer solution uses a water jet to break up the solids and pump them down the sewer solution waste exhaust hose, that water jet requires a water supply hose hooked up to the sewer solution to have pressure, thus you have the jet,........ that is where I had considered using the pocket hose,.....the "black tank flushing" I mentioned, was talking about the trailer connection where you attach a water hose for additional tank cleaning after draining the black tank,........the sewer solution waste exhaust hose is a 3/4" fabric reinforced very heavy hose, a pocket hose could never be used to replace that hose,...........

I guess its a moot subject now, I hooked up a brand new one today and the female end cracked when I put it on the outside faucet, back to the 3B's(Bed Bath & Beyond),, I tried it, it didn't work, I move on,...............thanks for everyone's input

I have 3 of the 50 ft green ones.
Home: My trailer sits nearly 100 ft from either faucet. It's the end hose to get to the trailer for adding water and cleaning. I even use it to connect to my pressure washer and no problem. The plastic male end shutoff sprays a fine mist so I can't leave it on (shouldn't with any hose anyways).

Camper: I keep two (one still in the package). I haven't used it for sites with full hookups yet (I keep two 25' white hoses for that odd occasion I'm parked too far away). But, where we boondock, the cg has potable water spigots throughout the cg. We've needed 300 ft of hose to get water for the fw tank at times. I had a 75 ft hose I kept in a bucket for those trips. I probably could have 5 or 6 of the pocket hoses in the same space.
