Is there anywhere in the  world I can get a simple replacement flap-cap for my freshwater inlet on my  2020 Tab 320?  One of the little thingies broke off (that keeps it secure when opened or closed) and my RV guy says it’s $200 to replace the freshwater inlet when the stupid cap probably cost 50 cents but is unavailable. Just that flat circular flap with the 2 little pieces that secure it in place.

    Possibly you could find and buy a replacement filler port assembly and just use the "flap" part off the new piece.

    You're not the first to look for it. https://tab-rv.vanillacommunity.com/discussion/comment/172075 
    Apparently the part was never available retail and the company has changed hands. Maybe a Nucamp dealer can still rustle the part up. In 2022 it was only $25. If the part is not available replace it with a generic gravity fill from Amazon or etrailer.

    @magicpony These threads show how to replace the "old" flapper water fill with the "newer" screw cap type water fill.

    Every thing depends on how much "give" you might have with the hose behind the installed water fill.  If there is not enough room to maneuver, this might be a harder process than it looks.  It is doable, however.

    Boy! Thanks for this. Ours is barely ever used but it has popped open and then the tank was taking on water. I didn’t know it was in there and when we let it out, it smelled soooo bad. We only have a grey tank, no bathroom, and create a wash station outside the camper. Right now, there is beautiful white duct tape holding it closed, very fancy!
