Just registered on this forum after finding it to be a very useful resource in learning about my new-to-me 2014.5 AI EXT. Many thanks to the participants of this very knowledgeable and helpful community
In preparing for my first trip (heading to NM first week of December), I've been testing out all the systems. Everything seemed to be working as expected until I got to dumping and flushing the black tank. The on-board tank monitor indicated that the black tank was empty or near empty. When I opened the dump valve and turned on the macerator, almost nothing came out. Here is where things started to get interesting. I wanted to use the black tank flush inlet located next to the dump hose, but when I connected the flush hose, water would not enter into the black tank. I have read on this forum that a likely culprit is an improperly installed check valve. I will have that checked out, but if there is anything else I should check, please let me know.
Since I couldn't fill the black tank this way, I decided to just let the toilet run so that the water from the fresh tank would fill the black tank. When the tank monitor indicated that the black tank was between 2/3 and full, I went outside to dump the black tank. Here is where the second unexpected issue came up. As soon as the black tank valve opened, I heard a rush of water under the coach. Peeking below, I could see water pouring out of the bottom of the coach onto the pavement. Luckily there was no sewage in the tank, but it still created a big cleanup headache as I had to sweep the water into the drain and hose down the pavement.
So, I would like some guidance as to what I should do next, particularly about the second issue. I've done searches online for this and I haven't had any luck coming across anyone describing such a problem with their AI black tank. FWIW, grey tank flush went without incident. Apologies in advance if I haven't included all the relevant troubleshooting info. I'm still quite new at this, so learning as I go.
Thank you in advance,
