Black Tank Flush works pretty good..

[jloco]

So right off the bat with my brand new Jay Flight, after I dumped the black tank for the first time, sure enough the gauge was still reading as 3/4 full. I ignored it until I dumped it for the second time at which point it still read 3/4 full. So I decided to give the black tank flush a try for the first time. (I wish I had one on my old TT)
I opened the black tank valve, connected a hose to the flush port, turned on the hose and let it flush for a good 4 or 5 minutes.. I checked the gauge again and it read 'empty'! I was glad to see that it did the job.

I really appreciate the tank flush, too.

You might add a clear elbow to your sewer connection. You can watch the 'stuff' run out during the flush. You may not need to run it 4-5 minutes at each dump.

I haven't timed how long I run the flush until there's no paper or solids, but I'd estimate it's 2-3 minutes each time I dump. Rarely does the gauge read any more than 1/4 full after dumping, but I also use the flush to add some water to the black tank when finished dumping (I really don't know how much I add).

Our old class B didn't have a tank flush or gauges. I wonder how much 'stuff' was stuck in the tank when I sold it?

I've found that I get more 'stuff' out if I close the black tank valve for a minute or two while I"m using the tank flush. Just have to be mindful not to get carried away.

For a minute or two, there is no way I'm filling the whole tank, but it builds enough water on the bottom to help dislodge some of the more stubborn payload.

my 2012 29 RLDS does not have a black water tank flush. I have a clear elbow that I attach and after I drain the black tank I fill it agaim by holding the pedal down for a few minutes and dump again. Then I take my wand and insert it in the toilet and move it around until the water comes out clean. My next trailer will have the tank flush and tinted windows.

Was this a stock Jayco flush or did you add it after. If added who is the maker.

Yeah that is a great idea.

But, like ya say use caution. Reminds me of the story our salesman told me when we bought our trailer. A couple just bought there trailer and the first camping trip they went on they hooked the water supply at their site up to the black tank flush (by accdent) and went on their business for several hours.....

Not really sure why they put those two connections right next to each other in the first place hahahah.

I was part of the optional elite package on my 2016. I believe the elite package is mandatory for 2017 jay flights
