Blank tank valve stuck

[Paigeb]

About to take out our brand new GD and are dewinterizing. We can’t open the black tank, never been used. Any suggestions?

Mine was same way. Spray with wd 40 or any other penetration liquid and with a pair of vise grips just wiggle the rod back and forth a tiny bit until you can pull it out
Then lubricate

Thanks Canada, we got it operating by removing the plastic handle, slipping a small closed end wrench over the slide, placed washers and then replaced handle screw snug next to washers. I had to tap pretty hard to break it free. It was surprisingly corroded considering it’s a 2021 camper. I’m a bit confused as to why they would use an aluminum slide inside steel shaft. That’s probably the most corrosive combination I can think of.

I wonder why nobody offers electronic valves for the gray and black tanks?

Quite sure some coaches do
I personally wouldn’t want them

Just posted this on another thread.

I had the same problem earlier in the year but was lucky and WD40 freed it up. Based on discussions on this site, I have ordered some ACF-50 (https://www.amazon.com/dp/B000P1C8UO...ing=UTF8&psc=1) to lubricate and plan on doing it regularly to keep it from sticking.

As a side note I ordered the above last Monday at $4 less than it is now. Seems Amazon prices fluctuate with how much is left in stock
