Black water hose: why a garden hose?

[Captcolour]

The difference in the two systems being that the fresh water system is terminated with faucets (pressure builds up - especially when faucets are closed) and the black tank flush is open all the time - minimal resistance and pressure.

Good point! Thanks.

Agree with all the regulars posting. I do not full time yet, but my rig is kept most of the year at our future retirement base camp at the coast. This is my set up.
First hose to the right is fresh water.
Middle hose is to the black water flush (a shorter white hose, marked as black water flush when traveling)
Left hose is a shorty that goes to a separate cleanout that feeds into my dump main (I run as much water as I can when dumping as I have about a 50' run to the street main.

I've been using Zero G's for five years with no problems. I use a blue one that is safe for drinking water and a black one that is just normal. The black I use for the black tank flush. I always put a pressure regulator on the pedestal and a Y connector (with shut offs) on it and connect the hoses as needed. I always screw the ends of my hoses together when they are stored in the RV and have separate storage containers to keep the black and fresh water components apart. I have an older one hanging on the side of the house, gets full Florida sun till noon every day, no regulator, it's a little faded but works perfect. No mold or flakes that I can see in any of them.

You may want to watch this review https://www.youtube.com/watch?v=WalzXF48iac changed my mind about Zero-G.

That's a nice camper canopy you have there.

As for a Zero-G hose "blowing," there is very little pressure in the black tank flush system since the sprayer is always open on the terminal end. I always kept two hoses to run all the way from the park water connection but, this past year, changed my ways. Inside the utility bay I've always had a water pressure regulator and a 90-degree elbow to reduce stress on the city water inlet fitting. I've recently added a lead-free brass Y just before the pressure regulator and got a 3' "metal flex" hose to run from the Y to the black tank flush inlet. I disconnect and drain this short hose at the black flush inlet after each use so, as @FT4NOW said, nothing gets contaminated. It takes me less time now and I don't have to mess with a second long hose. It's especially nice during cold/freezing weather. I'm a happier camper.

Why the metal flex hose to the black tank?

I've had this question since starting to research buying a rig and found no answers yet.

In our purchase, we were given a garden hose that has some kinks in it from being stored in too small of a black water container. It's quite an old hose anyway, so I was thinking of replacing it.

But why does everyone use a standard garden hose for the black water? It's big and bulky and typically less flexible than, say, a Zero-G. Is it the cost? Or will the Zero-G blow if you don't put the regulator on it in some cases (I assume you don't keep your regulator on when you attach your black water hose, right?)?

Second, I see RhinoFLEX advertised heavily but I also hear they are a pain to work with because it's not flexible when cold. I assume this is why the typical garden hose is used compared to RhinoFLEX.

All this begs the question, what's your recommendation for black water/flush hoses and why?

For my black tank flush, I cut about 15 feet from an old garden hose and put a new fitting on the cut end.
I don’t need a 25 or 50 feet hose for that purpose. I’ve used this for two trailers now.

Hi Rob. Love your setup. The added bonus being that the regulator is secured. But a question about the placement of the regulator at the end rather than at the source. Instructions for the regulator say to install at the source. But it looks like you haven't found a difference placing at the other end.

I have mine at the trailer end. Always have What would be the issue?
The water hose can easily handle higher pressure

Just because it was the most flexible really short hose I could fine. It has the bonus of being really well made with good connectors at each end.

Thank you. Where did you get it?
