Black tank flush ??
It seems like I should be able to hold all my newbie questions and ask all at once, but each time I visit this forum I learn something I should know about. Thank you all for that.
Anyway, my G19FD has a black tank flush hose connection. Can I assume that is an installed internal spray wash or is it more likely to be a fill and drain flush ?
Thanks , Roger

It's more an internal spray wash.
You need to have the sewer connection OPEN when you use the black tank flush feature. Also, having a clear connection similar to this straight one or the elbow ones available, will help you determine when the tank is clean. https://smile.amazon.com/Camco-Sewer...s%2C198&sr=8-2

It is a black tank cleanout port. It would only fill the black tank if the dump valve was closed, typically a no, no. Additionally, the black tank flush is a self contained system and is isolated from all other plumbing.

Thanks Folkes; That is what i was thinking , but felt it good to verify; I can certainly understand NOT having the black tank valve CLOSED; what a problem that could be inside the RV. I have all the parts suggested and will be hooking up for real on Wed for our first trip out; couple nights in Kanab.
Thanks, R

R, Thanks, I'm a New Bee as well, thanks for asking so we all can learn. Enjoy Kanab. Currently am in the Oregon coast. I just emptied the black then grey tanks, but didn't know enough about the flush to use it yet.
I've had some prior older rv "black tank dump" fails, it's not my best skill set yet, but nothing like a fail to learn fast!

Black Tank.
Look into the geo method to ensure a clean tank and sensors,

Kanab - Is that restaurant still on main street with the photos of all the old western movie stars on the walls? Haven't been there since about '08. They said that Kanab was a center for those movies and those folks would eat there when making them.
Sorry for the hi-jack but it seems your question has been answered. One thing I found is that when using the flush inlet if you have too much pressure it's not so good. Not a pleasant odor.

I guess I somewhat go against the conventional wisdom. When I dump our black tank, my next step after dumping is to check the full meter. If it doesn’t show empty, I close the valve and use the tank flush to refill the tank. That is the easiest way to refill and get a full dump to remove objects that might be stuck. OF COURSE you must closely monitor the meter to make sure not to overfill!! As soon as the meter starts to show full, I shut off the flush and dump again. This seems to work really well and generally is a quick way to refill the black tank.

Having not had a black tank flush on my previous Rockwood and having one in my current TT, I can say that I love it. Gets more stuff out of my black tank, than I did with a flush wand and Dual-Flush attachment. And it is so simple to put water back in, after dumping.

Flush black from the inside
After emptying the black, i close it and go inside. I have an old mayo plastic jar cut in half. The cap end fits perfectly into the toilet. The water goes over the jar and into the black tank. I set a timer for 18 minutes and STAY IN THE AREA. I then remove the mayo jar and keep my foot on the flush for about another two minutes. I can easily tell when tank is tippy top ful and stop the gill. Then back outside and redump. Works greT!

I had a good suggestion made to me about the black tank flush. You might try it. After you dump and turn your flush on, let it run for a short time. Then close black tank valve for a short time. Then with the flush still running open black tank valve. I ddo this several times. You be surprised what will come out.

I do the same as grease monkey. Each time it loosens a bit more. Also a clear 90° or a 45° to see the difference. Just don't get distracted and walk away from a closed valve with the tank rinse on.

I set the stop watch on my phone for 2 minutes and dump after that several times. Then let it run open while I do other stuff.

Paul. Likely it’s the Rocking V. It’s been a while and I really don’t remember, but it’s been there for quite a while.

Thanks for asking
Thanks for asking this question. You Tube can be great at informing you or confusing you. I have watched several videos from the "experts" who RV full time on how best to dump and clean the black tank. There are as many methods as there are videos.
I have the Black Tank flush connection on my TT. I think I will follow the most often described method which is dump the tank, close the valve, fill the tank (keeping an eye on the levels), open the valve, repeat until clear. Hopefully, that will give me the best result.
As a relative newbe I too learn a lot from this forum. Thanks for all of the advice and knowledge you seasoned RV'ers give us new guys.

I do the same thing except I don't use the meter to let me know when the tank is almost full. I don't trust the lights enough to do that. Instead, I shut off the water pump and stand in the bathroom with the toilet flush valve open and watched the tank fill so I can see when it is getting close to the top.

I'm not convinced my flush system works that well. I could have a kink in the hose somewhere. When I run it, it seems the outflow is less than it should be.
On my old trailer, I installed an aftermarket flush sprayer, and it was really obvious when it was working.

I hope the above link works. I always dump the tank and use the water meter above to measure how much water is going into the black tank. No guessing on time, no hoping the sensors work, no need to go inside.
For $15.00 it is great peace of mind. I will typicallly flush and refill 3 times before not seeing any paper flushed.

I use the same method, and apply the Geo concept at the end by adding 1 cup of Calgon along with 1/2 cup of Dawn and let it sit till the next dump. This seems to really help keep the sensors clear of debris.

It's possible that the black tank flush is not working the way you want. The solution by 360true and others will help flush that tank efficiently. Filling the tank more than once with water and dumping is going to give you the 'flushing' that you're looking for.
